AC Coil Cleaning(by Sid [MD]) Posted on:Jul 15, 2012 5:01 PM

New landlord to maintenance expenses. Had AC maintenance to a townhouse unit and was told the system needed coil cleaning. Contractor gave me a cost of $326 to clean the coil and said the work would take about two hours and they would have to reschedule to come back to do the work. First, does anyone know if $326 sounds reasonable for a coil clean to an AC, and second does cleaning a coil usually take about two hours to do.

I was really surprised when the contractor told me the work had to be rescheduled for another time. It seems to me, if you are in this business of servicing air conditioners and it is definitely the season for this type of work, I didn't understand why the coil cleaning couldn't have been done at the time of the maintenance service. I assumed the real reason may have been the tech didn't have time for the service -- I don't know.

Does anyone have any experience with this type of maintenance. I'm sure the unit may very well need coil cleaning but does the cost and amount of time for this service sound reasonable?

Thanks for your responses.

Inside coil or outside? Big difference in time and labor depending on which on.

AC Coil Cleaning(by Sid [MD]) Posted on:Jul 15, 2012 5:27 PM

Inside coil

AC Coil Cleaning(by V [OH]) Posted on:Jul 15, 2012 6:09 PM

Inside coil involves much more stuff to remove, this is like lifting the top off the furnace - twist it open somehow and hope everything goes into the drain pan, in my days of residential these get grocery bags blown into the bottom blocking the air flow when somebody takes out the filter and then the unit starts to run, in commercial freezers one bag like this will block/freeze the walk-in cooler for 3 days waiting for all the ice to melt away - take food to other stores or hide in another chiller.

AC Coil Cleaning(by allin [VA]) Posted on:Jul 15, 2012 7:53 PM

He will probably pull the charge and cut the coil to take it outside to clean with spray and hose. If it is very bad then that is the best way. If not too bad then it can be sprayed in place and then let the condensate wash the coil off.

AC Coil Cleaning(by Sue [IL]) Posted on:Jul 15, 2012 7:57 PM

Have had this done twice this summer at two different properties. One was $75 - the price of a service call. The other was $120 because it was more time-consuming to clean- 1.5 hours.

AC Coil Cleaning(by gevans [SC]) Posted on:Jul 16, 2012 5:47 AM

As Allin said, he will likely be pulling the charge, removing the coil, and cleaning it outside. It's the best way to do it, but definitely the most expensive.

Things to consider when setting price:

Is it in the attic or interior? If so, water/cleaner will damage the ceiling, carpet, floor, etc. and the coil should therefore be cleaned outside.

Is it easy access? Some coils pop right out, others you have to remove every screw in the unit to access.

How dirty, and what type dirt? If it's impacted into the coil, you can't do a good job cleaning it in place, it must be removed.


AC Coil Cleaning(by Mary Morey [FL]) Posted on:Mar 13, 2013 1:55 PM

Yes. About $325.00 to $400.00 is the going price to have AC Coils cleaned.

And Yes a planned date is necessary and it does take about two hours or more.

Don't complain about the price. I paid $2,000.00 for a cleaning and they kept telling me I needed more services to be done to it!

Beware of AC Contractors and check first with the Better Business Bureau in your area to see what type Rating they have.

The co. that gave me an estimate said 571.00.Where is mary morey in fl what co did she use.

AC Coil Cleaning(by Martha [TX]) Posted on:Jun 18, 2013 6:37 AM

A coil unit is only a few hundred dollars. It seems a replacement would be a better deal than a 575 cleaning.

How Long Does It Take To Clean Ac Coils

How Long Does It Take To Clean Ac Coils

How long does it take to clean the AC coils?

First, some know if $ 326 is reasonable for a clean AC coil, and second, it typically takes about two hours to clean a coil.

And how much does it cost to clean the AC coil?

AC Coil Cleaning Costs AC coil cleaning as a standalone service costs between $ 100 and $ 400. For the system to be as efficient as possible, you should do it annually and no more than once a month. Cleaning the condenser coil located outside the home is done with the annual air conditioning setting from $ 75 to $ 200.

How can I also know if my AC coil is dirty?

The most obvious sign of a dirty evaporator coil is a general drop in system pressure. If you know the normal pressure for your system, you should be able to determine if the current pressure is below this value. If so, it's probably your fault that the vaporizer is dirty.

Also, you may be wondering how often do evaporator coils need to be cleaned?

In order to minimize energy consumption and reduce energy costs, the airflow logs should be cleaned at least once a year. It is estimated that dirty evaporator and condenser coils can increase the power consumption of the air conditioner by more than 30%.

What if the AC coils are dirty?

What if your air conditioner has dirty condenser coils?

Your home is not cooling properly. As dirt accumulates on condenser coils, it forms a layer on the coils that acts as a barrier between the air blown on the coils and the heat of the refrigerant flowing through them.

Can I clean the air ducts myself?

You don't clean the air ducts yourself, even if you were tempted to, you probably don't have the right tools like special rotating brushes and a powerful vacuum cleaner. You have to hire professionals and the cost is not low.

Help to clean AC coils?

With regular cleaning of the air conditioning, the system is less likely to malfunction because it does not have to work as hard to achieve the desired comfort level. Clean coils help your wallet as your electricity bill is lower. With clean coils, the system runs less and consumes less energy.

Is cleaning sewers a waste of money?

Cleaning every 57 years by a company that doesn't waste money on sewer cleaning can alleviate a number of problems. Proper duct cleaning can reduce the amount of dust that the HVAC system emits into the home. Another reason for cleaning sewers is to renovate a home.

How do I know if my air ducts need to be cleaned?

5 characters You should have cleaned your ducts You haven't replaced your air filter in months. Ventilation logs and hoods show visible dust. You can spot mold in or around the HVAC system. The air flow is not homogeneous from one room to another. Noise is heard in the canal.

How much should an air conditioning system cost?

The average cost of an HVAC installation ranges from $ 100 to $ 200, with prices depending on the size of your home, the type of system you have, the age of the system, etc. The average cost of HVAC repairs. The average cost of an HVAC repair is between $ 120 and $ 1,000 or more.

Is it really worth purifying the air?

Cleaning sewers has never been shown to actually prevent health problems. Studies also do not show with certainty that the amount of particles (e.g. dust) in apartments increases through dirty air ducts. Much of the dirt in air ducts sticks to duct surfaces and is not necessarily found in living spaces.

What is the best air conditioner coil cleaner?

These are the best dry cleaners on the market today. NuCalgon 429108 NuBrite. ComStar 90100 Coil King Cleaner for alkaline coils for external capacitors. NuCalgon 417175 Evap Foam evaporator dish detergent without rinsing. ACSafe foam coil cleaner. Foaming cleaner for CRC coils.

Can I clean the AC coils with vinegar?

Take the spray bottle, vinegar and water. Mix the water and vinegar in the bottle. Shake the solution well and apply it to the evaporator coil and condenser coil. Vinegar does not damage parts and is a very effective cleaner.

Can you use bleach on the evaporator coils?

A vaporizer can remove several liters of water from the air in one day! The condensation will do more than just wash the coils. I always spray the coils with a mixture of bleach and water with a garden sprayer to prevent mold growth. About 1/2 to 1 cup of bleach per liter of water is fine.

Can you spray water on your air conditioner?

No, do not clean the outdoor unit by watering it with the garden hose. Water pressure can bend the fins surrounding the condenser.

Do you want the air conditioning to work all day?

On a typical summer day, the air conditioner can be expected to run for approximately 15 minutes during each cooling cycle. However, if the cool down cycles last 30 minutes, an hour, or all day, then there is very likely something wrong with your system.

Can dirty batteries affect cooling?

A dirty condenser coil affects, among other things, an air conditioning system, reducing the overall efficiency of the unit. A dirty condenser coil has reduced its ability to transfer heat to the outside air, which can result in a less efficient cooling system.

How Long Does It Take To Clean Ac Coils


How Much Do Dirty Coils Cost You?

The short answer is PLENTY! Dirty coils, or anything that blocks the free flow of air into or out of the evaporator and condensing units can cost you in several big ways:

It will cost you more in electrical energy to run all of the system’s components longer and harder, especially the compressor.
Your refrigeration system may not be able to keep up and a too high temperature may prompt you to call for expensive emergency service.

Your equipment may fail prematurely due to the increased strain dirty coils place on its operation. Refrigerant can return to the compressor as a liquid and cause it to fail due to “slugging”. Replacing a compressor is a capital expense that you would probably want to put off until another day.
Unfortunately, cleaning evaporator and condenser coils is one of the most overlooked maintenance jobs there is. Although your coils are always getting dirtier, even right now as you read this, it is much easier in the short run to just ignore the problem and hope it won’t catch up with you. However, given enough time, it always will. The longer you go between coil cleanings and the dirtier they get, the more it can cost you. It is much smarter and cheaper in the long run to institute a regular preventative maintenance program with coil cleaning being one of the top priorities. How often is regular? Cleanings should certainly happen at least yearly and perhaps more often, depending on how dirty the environment is in which the coils are operating.

Having clean coils makes your system more efficient. Evaporator coils pick up heat from the air circulating inside the building. Condenser coils transfer that heat to the air outside the cooled space. Just by having the evaporator and condenser fans operating and pulling air through the coils, dirt and dust is deposited on them. Dirt and dust are poorer conductors of heat than bare metal, so it takes air passing through dirty metal fins that are attached to the coils of the evaporator and condensing heat exchangers for a longer time to exchange the same amount of heat as clean fins. Dust, especially, can build up over time and reduce the spaces between the fins, so that less air is able to pass through the fins with the same amount of fan power. Let the crud build up as badly as the condenser shown above which is just like an evaporator coil covered with frost that chokes off the airflow, the efficiency of your system will suffer due to increased compressor and evaporator run time.

Without accurately testing the electrical energy going into and the heat coming out of your particular refrigeration system, before and after a coil cleaning, it is impossible to state for certain how much those dirty coils are costing you. Based on such testing of several randomly selected residential and commercial systems industry studies estimate that dirty condenser coils alone are costing the owner of a typical commercial refrigeration unit between $220 and $625 a year in electric energy waste. Assuming an average of $400/unit/year that amounts to a total of $9.7 billion annual loss for the estimated 27 million commercial systems in the U.S. That’s a lot of wasted energy and money!

Many energy-related organizations warn of the danger of neglecting coil cleaning. The U.S. DOE advises that “a dirty condenser coil can increase compressor energy consumption by 30 percent.” and recommends inspecting coils a minimum of once per year. Pacific Gas & Electric (PG&E) also suggests an annual coil cleaning to its commercial customers as part of its ongoing efforts to promote energy-efficient HVAC-system operations.

The Federal Energy Management Program (FEMP) did a study that had some specific findings: “A dirty condenser coil that raises condensing temperature from 95°F to 105°F cuts cooling capacity by 7 percent and increases power consumption by 10 percent, with a net (compressor) efficiency reduction of 16 percent. In a 10-ton unit operating 2,000 hours a year, this wastes about $250 per year in operating costs. A technician can clean the condenser coil in about 1 hour, which typically costs about $150. In this example, the payback takes just over 7 months.

To make matters worse, dirty condenser coils are perhaps even less than half the story. That is because there are two types of heat exchangers in almost all refrigeration systems that collect dirt from the air passing through them: condenser coils, located outside the cooled space, and evaporator coils, located inside the cooler. Evaporator fans usually run all of the time, or about twice as much as a typical condensing fan, so they have twice the amount of time to collect dust and dirt from the air passing through the fins. And, unlike air conditioning systems, evaporators for refrigeration systems do not have filters that can be replaced, so the dirt builds up on, and in between, the coils and fins themselves.

While also delivering less air, all types of evaporator fan motors themselves consume more energy whenever the airflow is constricted. The Northeast Energy Efficiency Partnership (NEEP) performed tests in which the airflow through an evaporator unit’s coils was blocked in varying amount by sheets of styrofoam to simulate blockage by dirt and dust, frost, or boxes of product stored too close. They found that an old-fashioned shaded pole motor’s used 104 watts when air flowed freely through the unit, but that it increased 20% when they completely shut off the flow of the air, like what one might see with a totally frosted evaporator. An energy-efficient ECM evaporator motor of the same size fared even more poorly, relatively speaking, by burning 43 watts with clean coils and 60% more, or 69 watts, with the styrofoam covering all of the coils. Blocking the airflow in by 75% and an ECM used 23% more energy. Even blocking the flow of air out of an evaporator by only 50% increased the power consumption of either kind of motor about 16%.

What can we advise from this data?

Raise the evaporator temperature by efficiently moving as much air through the evaporator coils. This can be done by regularly (at least annually) cleaning the evaporator coils, straightening any bent fins, being sure that the coils are completely unrestricted, and not blocking the flow of air into or out of the evaporator.
Lower the condenser temperature by efficiently moving as much air through the condenser coils. This can be done by regularly (at least annually) cleaning the condenser coils, straightening any bent fins, and not blocking the flow of air into or out of the condenser.

So the question is: When was the last time you had your coils cleaned?

AC Coil Cleaning

Subsequently, one may also ask, how often should evaporator coils be cleaned?

To minimize energy usage and reduce utility costs, the A/C coils should be cleaned at least once a year. It is estimated that dirty evaporator and condenser coils can increase the energy usage of your air conditioning system by over 30 percent.

Secondly, how much does it cost to have your air conditioner cleaned? Average AC & Furnace Cleaning CostsInspecting and cleaning just the furnace costs $100 to $300 or up to $500 if you include an AC unit. Cleaning an AC unit alone runs $50 to $200. Duct cleaning services include any parts of these that air passes over, including the blower, fan and heat exchanger.

Secondly, how long does it take to clean AC coils?

AC Maintenance Cost by Task

Some tasks could be added to your AC service. These add-ons range from as low as $25 for a thermostat replacement to as high as $1,000 for duct cleaning. These additional tasks may be recommended after the inspection portion of your AC maintenance and are likely necessary to improve function and prevent larger problems. Below are some of the most common add-ons and what you may anticipate paying for them.

AC Maintenance Cost by Task: Evaporator or Condenser Coil Cleaning, Air Filter Replacement, Thermostat Replacement, Drain Line Cleaning, Refrigerant Recharging, or Air Duct Cleaning

AC Coil Cleaning Cost

The price of AC condenser or evaporator coil cleaning is $45 to $350. The evaporator coil is located in the unit inside the home. Its job is to cool the heat from the indoor air. The second coil is the condenser coil, which is inside the outdoor unit. The condenser coil moves energy in and out of the home. Both these coils are vital to the operation and efficiency of your system. When they become clogged with dirt or debris, it lowers the output of the system or even causes it to break down. Some HVAC companies include this service during their maintenance visit without additional charge. You should inquire with your HVAC company to determine their policy.

AC Filter Replacement Cost

Replacing a filter costs from $75 to $195. Home AC filter replacement is by far the most crucial step to maintain the integrity of your system and provide a long life. Clogged filters can lead to poor airflow, which can damage parts and lead to breakdowns. Homeowners are encouraged to change their filters every month. Your technician will check and replace your filter if necessary as part of their routine maintenance visit.

MERV rates the amount of dust and particles allowed through the filter. Choose a filter with a MERV rating of at least 11 to 16 for your home. Lower MERV ratings result in lowered energy efficiency and may not provide the allergy protection necessary for all members of your household.

Dirty Home AC Filter Being Replaced

AC Thermostat Replacement Cost

Replacing a thermostat 1 run between $150 and $480. There are many AC thermostats: programmable electronic, touchscreen, smart thermostats that range from $130 to $300, and voice-control. Gone are the days of the dial thermostat where you moved a small wheel to choose your temperature. Thermostat replacement can be a common occurrence both during maintenance of an AC unit or the repair process. Thermostats can break, which can fail to signal the system properly, causing it not to respond when needed.

Professional Replacing AC Thermostat

AC Drain Line Cleaning Cost

Your technician may inform you that you need your drain line 2 cleaned, which costs between $75 and $200. As dirt, allergens, and debris circulate through the evaporator coils, they can become clogged by moisture and buildup. Eventually, this debris travels through the drain line, where it inhibits the flow of water leaving the system and eventually creates a clog. A clogged line inhibits function and results in rust in the system.

AC Drain Line that Needs to Be Cleaned

Home AC Recharge Cost

A home AC recharge costs $200 to $500, including checking the freon level in the home AC. Freon 3 is the coolant in your air conditioner. It is normally a lifetime supply unless leaks or repairs allow the freon to leave the unit. To recharge the freon, the contractor first checks the temperature with a pressure gauge. Once it is determined you need more freon, a tank of freon is hooked up to your system’s pressure ports and fills the system with the freon needed.

A licensed contractor must perform this procedure because laws are in place to protect the environment. After 2020, no freon will be produced as it is harmful to the environment. Newer systems have already made the switch to a new product called Puron. Older systems before 2010 will be replenished with recycled freon and eventually phased out. Most homeowners cannot obtain freon legally because you need a professional certification to do so.

Contractor Recharging Home AC Unit

AC Duct Cleaning Cost

Duct cleaning costs range from $350 to $1,000. Ducts are cleaned by vacuuming out all the dust and debris from the ducts located in the house. The buildup can cause allergies and make your system less energy-efficient. In addition, your AC will need to work harder, and more repairs will be needed. You should have your ducts cleaned every three to five years or more often if someone in your home suffers from severe allergies.

AC Maintenance Cost by Type of Unit

The AC unit type influences how much you will pay to have it serviced. You can pay anywhere between $50 and $400 for maintenance, depending on the type of system. The price varies because each type of unit has its own specific parts required for functioning. Additionally, different units require different types of cleaning and maintenance and refrigerant levels. Below are the costs you can expect to encounter for each type of unit:

Maintenance Cost of a Portable AC, Window AC, Central Air, Packaged, Swamp Cooler, Geothermal, or Ductless Mini Split Unit

Maintenance Cost of a Portable AC, Window AC, Central Air, Packaged, Swamp Cooler, Geothermal, or Ductless Mini Split Unit

Portable AC Maintenance

A portable AC can be moved from room to room or mounted on the wall. The maintenance cost is $50 to $85. A portable AC is similar to a window unit and has some of the same problems. When it comes to maintenance, your technician will change your filter, drain the water, clean the exterior and check for any parts that may need repair. Annual maintenance is sufficient for most portable units

Window AC Maintenance Cost

Window AC systems are fairly uncomplicated and only require an annual tune-up at the cost of $50 to $100. During your maintenance visit, the technician will inspect and clean the evaporator coils that likely have built up dust throughout the year. They will clean or replace the filter and check the coil fins, making sure they are clean and straight.

Central Air Maintenance Cost

It costs about $85 to $150 to service a central air system. Maintenance of your central air system should be done once a year to keep it operating efficiently and reduce your risk of a breakdown. Maintenance involves a thorough inspection of parts, such as belts, bearings, and the motor. Your technician will clean or replace your filter. During the process, they clean the dirt and debris off of all the components. Once this is complete, they check the refrigerant and adjust the levels, if necessary. During the inspection of your outdoor unit, they will remove any debris from your fins and straighten any that may have become bent.

HVAC Package Unit Maintenance

Packaged HVAC Units cost a little more to maintain than an AC unit on its own, running between $90 and $200. These systems have both the heating system and AC system in one unit. Your technician will perform the same tasks as they would for a central AC unit. But they will check the components of the heating system since they are one unit.

Swamp Cooler Maintenance Cost

Maintenance on a swamp cooler 4 runs between $100 and $150 and should be done annually. These units are not meant for humid, hot environments. They require a cracked window and a steady supply of water. The maintenance on these units is minimal compared to others but often includes pad replacement in the cost, leading to an overall higher price. In addition to pad replacement, your technician will empty, clean, and inspect the drain pan.

Geothermal AC Maintenance

Geothermal systems can be more costly than others to install, repair, and maintain. On average, maintenance costs run between $175 and $350. These systems usually go long without needing repairs, but having annual maintenance ensures the system operates at peak efficiency. Maintenance involves filter changes, inspection, cleaning, and lubrication.

Ductless Mini Split Maintenance Cost

Maintenance costs of ductless systems can be more expensive, running between $200 and $400. Ductless systems operate without ducts, eliminating any duct work problems or the need to have them inspected. Yet, the fact that ductless systems have separate indoor units means that each one needs to have maintenance performed during the technician’s visit. During the visit, they will inspect and clean the exterior unit, change filters, and apply a fungistat or bacteriostat to prevent the growth of bacteria in the system.

AC Maintenance Plan Cost by Frequency

The cost of your maintenance plan depends on the frequency of your visits. Prices range from as low as $75 per visit to as high as $250 per visit. Regular maintenance extends the life of your AC unit. Regular tune-ups could cost less if you have an air conditioner maintenance plan. You can choose an option that best meets your needs, from annual tune-ups to quarterly plans.

Cost per Visit of a Quarterly, Semi-Annual, or Yearly AC Maintenance Plan

Cost per Visit of a Quarterly, Semi-Annual, or Yearly AC Maintenance Plan

FrequencyCost per Visit
Quarterly$75 - $150
Semi-Annual$100 - $200
Yearly$150 - $250

AC Quarterly Maintenance Plan

A quarterly maintenance plan costs between $75 and $150 per visit and provides you with four visits throughout the year. Visits will be broken up with one each season. Each visit costs less than other plans as the major maintenance projects will only be done once or twice a year. Coil repair and straightening will likely be done in the spring, and lubrication of the parts will likely be done in the fall. Every visit will include a thorough inspection, cleaning, and filter replacement, and one or two other maintenance tasks that should be done throughout the year. This plan is a good option for those with older systems that are more likely to have efficiency problems

AC Semi-Annual Maintenance

AC semi-annual maintenance runs between $100 and $200 per visit and includes a visit in the fall and spring. Aside from the normal inspection, cleaning, and filter replacement, these visits often include a refrigerant check and replacement at each one, if necessary. It will also include a cleaning of the outdoor unit and repair of exterior unit fins, if necessary. This option is great for units still under warranty as it can help you catch repairs while in the warranty period.

AC Yearly Maintenance Cost

Yearly AC maintenance plans are the most common and run between $150 and $250 per visit. These plans are sufficient if your system is not too old and has not had many repair issues. An annual visit includes all items on the tune-up list and helps keep your system running as efficiently as possible. Since these plans are only once per year, they will likely include both the maintenance of your AC unit and heater.

AC Service Cost

Servicing an AC unit can become a lengthy and complicated process. Unless you have extensive knowledge about the operation and repair of an AC unit, it is probably best to hire a professional. It can take anywhere from an hour to several hours to service the unit, depending on the amount of dirt buildup, unit size, and how easily accessible it is. In addition, if the system requires any repairs, this adds to the time spent on the service call. Routine maintenance is usually done at a flat rate of between $75 and $300. This cost includes the AC diagnostic cost. If the call turns into a repair situation, expect to pay $60 to $75 for the AC technician’s hourly rate plus parts.

Another consideration is an extended maintenance plan. Suppose your system is out of warranty, an HVAC unit, or over ten years old. In that case, you may want to purchase a plan that includes priority service, any home AC diagnostic costs, discounted services and cleanings, refrigerant recharges, winter checks (off-season discount), inspections, and tune-ups. An extended service contract costs $175 to $450 annually. The cost depends on the type and length of the contract. If you are concerned that your system may require extensive repairs, a maintenance plan is a wise choice.

On average, you can expect to pay between $100 and $150 to have an AC unit inspected. It is recommended to have your AC unit inspected at least once a year, even if you aren’t having problems. This helps keep the unit functioning as efficiently as possible. If you have a regular maintenance agreement, the inspection cost will usually be covered in the plan.

Besides regular inspections, you may need to have your system inspected if you feel that the output is less or notice your energy bills are higher than expected. It is also a good idea to have a unit inspected when deciding whether or not to purchase a home to make sure there are no surprises when you move in.

During the inspection, your technician thoroughly examines all of the system components to make sure they are clean and working properly. They will also check for any possible hazards and ensure all of the safety features are functioning properly. Finally, they will check the components connected to the unit, such as the flues, vents, and ducts, to see if they are built up with dirt and debris. After the inspection is complete, they will make recommendations for cleanings and needed repairs.

What Does an AC Tune-up Include?

Tasks included in an AC tune-up vary according to the professional you hire and the type of system you have. Here is a standard checklist for a tune-up:

  • Clean or replace air filter (if the unit has one).
  • Check the airflow of the evaporator coil and use a special cleaning agent to clean the coils.
  • Flush the drain lines to combat mold and mildew.
  • Inspect and test all electrical wiring connections, check the safety and appropriate rating, and test capacitors, valves, and fan blades.
  • Check the blower motor to ensure amps and voltage are working correctly.
  • Clean and test all duct work and check refrigerant level.
  • Test and calibrate the thermostat. Measure temperatures coming from all returns.
  • Lubricate all moving parts. Check all bearings for wear and tear.
  • Inspect the caulk 5 on a window unit.
  • Inspect and repair the electrical parts. Measure amp and voltage draw on the condenser.
  • Look for worn or loose motor belts or pulleys and repair where appropriate.
  • Remove any debris in or around the compressor, condenser, and fan. Brush any bent coil fins back into shape.
  • Check airflow of blades and blower wheel.

How Often Should You Get Your AC Serviced?

You should have your AC unit serviced at least once a year. However, HVAC technicians may steer you to bi-annual maintenance in some areas. If you live in hotter climates, your system will likely get much more use, leading to earlier wear and tear. Having service twice a year helps you stay on top of minor repairs before they turn into major problems. Bi-annual service can catch any possible defects within the warranty period.

Technicians also recommend that older units have bi-annual service to help them operate as efficiently as possible and reduce the risk of breakdown.

AC Maintenance Cost Factors

AC maintenance cost factors vary according to several circumstances, including:

  • Size and efficiency. The larger your system, the more maintenance will cost. However, if your efficiency is higher, utility costs should be lower, which balances out the maintenance cost.
  • How old the unit is. The older the unit, the higher the chances you will need repairs and replacement parts.
  • Repairs needed. The number of repairs can increase the cost of a simple tune-up substantially. For example, in a central air unit, unclogging a condenser line costs $100 to $150, while a new condenser is $475 to $600. Window unit repairs may consist of a capacitor replacement of $150 or a fan motor costing $325.
  • Time of year you have the work done. During the hotter months, it is more expensive to get AC maintenance done. You may wait longer because AC companies are busy with repairs. Expect to pay $90 to $140. Winter tune-ups cost $75 to $90.
  • Regular maintenance. If you have been doing regular, preventative maintenance, such as changing/cleaning your filter, keeping debris away from the outside unit, and vacuuming out your vents, you are less likely to need repairs.
  • Accessibility. If your equipment is not easily accessible, the rate may be higher. If the technician has to cut down overgrown foliage or move things around to get to the unit, you could be charged a prep fee for the time it takes ($60 to $75 an hour).

Benefits of AC Maintenance

There are many benefits to having your AC unit regularly serviced. For newer units, it helps you catch potential problems while they are still covered under the warranty period. For older units, it keeps them functioning as long as possible. But no matter the age of your system, regular maintenance helps you keep your system running as efficiently as possible, save you on energy bills, and help you catch problems while they are still minor.

How to Save Money on Your Air Conditioning Bill?

Everybody likes to save money. Saving on your electric bill can be accomplished by simply changing some habits. Open the windows on cooler days and keep drapes and blinds closed to keep the heat or cold out when appropriate. The closer your indoor temperature is to the outdoor temperature, the less your system will have to run.

Use auto modes with a programmable thermostat to ensure your system only runs as needed. Programmable thermostats keep the air from running when you are not at home and kick on about an hour before your arrival. Many AC systems include an ‘eco’ mode. This setting allows your compressor to increase the fan speed while choosing a temperature that is two degrees higher than the thermostat setting. The room will still feel just as cool, but your energy bill will go down.

Another way to save energy is to circulate the air by keeping your fans running. This is true even during the winter. Ceiling fans have a setting for winter circulation.

You can reduce the overall heat in your home. Using energy-saving light bulbs and avoiding using the oven on hot days, you can reduce the amount of energy used to cool your home. The heat from a clothes dryer makes the house hotter. Make use of the great outdoors and hang your clothes outside.

Additional AC Maintenance Tasks

When you schedule your air conditioner tune-up, be prepared for additional costs, particularly if you have not had it serviced in a long time or if the system is older. These costs are most often associated with repairs that need to be made to ensure that your system is safe and continues to function efficiently. In addition to repairs, your technician may have to perform a more extensive cleaning, especially if you have not had your system checked in years. Below you will see some of the most common additional costs you may encounter after your system has been inspected.

Emergency AC Maintenance

Emergency calls can cost $135 to $200 per hour to have your AC system serviced. Calls are deemed emergency calls if a technician has to come out aside from normal business hours, either on the weekends, evenings, or holidays. While most emergency AC repairs can wait until normal business hours, certain repairs warrant emergency attention, such as refrigerant leaks or problems with the motor. For homeowners in areas with high temperatures, sometimes discomfort can be a motivating factor for an emergency AC maintenance call. No matter the problem, it is best to shut your system off and wait for your technician to arrive to avoid more severe or dangerous problems.

AC Preventative Maintenance Cost

General maintenance keeps your system clean and functioning properly. In between service calls, change out or clean the filter monthly and keep the area around the condenser free of debris, plants, trees, and shrubs. A programmable thermostat ($25 to $85) monitors the temperature and keeps the system from running unnecessarily. If you are a little mechanically inclined, you can clean the coils and fins on the outside unit and the vents inside the house regularly.

There are many parts in the AC, but the most important part is cleaning or changing the AC filter regularly. It is suggested that you do this monthly or quarterly, depending on the amount of dirt and/or allergens in the air. Other things that prevent excessive dirt and debris are to keep trees and shrubs away from the outside unit, clean the vents and intake regularly, and flush with a bleach solution. This regular maintenance avoids straining your system.

Inverter vs Non-Inverter AC Maintenance Cost

The cost for maintenance on an inverter AC unit is between $150 and $250. A non-inverter unit runs around $125 to $200. These units are more expensive than traditional central units to maintain because it requires more cleaning, and the parts are a little more difficult to reach. The price is higher for inverter units due to the more complicated compressor, which takes longer to inspect and clean.

The primary difference between these and traditional systems is that your traditional system will run your blower at a fixed speed and be controlled by an on and off switch that your thermostat can trigger. Inverter and non-inverter units have the power going constantly based on the demand for cool air.

Both types of systems have similar maintenance tasks. You can expect your technician to change the air and bacteria filters, clean the cooling fins and coils, apply an antifungal spray, and flush the drain lines.

Both inverter and non-inverter systems are extremely efficient and great for small spaces. The primary difference between the two is that a non-inverter cannot regulate the compressor speed.

A non-inverter system runs on high until the desired room temperature is reached. This can make it extremely noisy to operate.

Other benefits of these two systems include their ability to control heat and humidity and their variety of installation options. The main drawback is their cost.

Enhancement and Improvement Costs

Exposed Duct Insulation

Insulating your ducts helps your unit run more efficiently because it keeps the heat out and the cool in. Duct armor is a rubberized liner that goes inside of the duct via spraying. The cost is high at $2,000 to $10,000.


A MERV 8 rating is a good rating. However, for better dust filtration, a MERV 11 to 16 air filter is recommended.

  • How do you know if your central air needs freon?

Signs you need freon include ice forming on the outside unit, the unit is not cooling the house, any hissing sounds coming from the unit, or warm air coming out of the vents.

  • How often should you have your AC serviced?

While bi-annual service provides you with the best chance of catching possible repairs before they become major problems, annual maintenance on most systems is enough to keep them running efficiently. If you choose bi-annual service, it is best to have one in the spring and one in the fall. If you choose annually, spring will be your best option.

  • Which air filter is best?

Choosing an air filter is important because it helps the system run the best it can. The basic recommendation by professionals is to find a filter with a high MERV rating, around 11 to 16. MERV refers to the amount of dust and dirt allowed through the filter.

  • What does AC maintenance include?

AC maintenance includes a thorough inspection of the system components, filter changing or cleaning, a system cleaning, and a check of all safety protocols. Depending on the system, adding refrigerant may also be part of the process.

  • Will an AC fan run if the compressor is bad?

Yes, the fan will run if the compressor is bad. However, if the AC fan is working, there may be another problem unrelated to the compressor. This could include a faulty thermostat, coils, or filter that needs to be cleaned, a capacitor or relay switch that needs replacing, or other issues.

  • Is annual air conditioner maintenance necessary?

An air conditioner consists of many moving parts. If the unit is regularly serviced, there is less chance those parts will become broken or inoperable. There are no guarantees the system will last longer. However, the chances go up when it is properly maintained.

  • Do pleated air filters restrict airflow?

Many arguments say pleated air filters restrict airflow. However, most professionals agree that pleated filters are a great choice for those with allergies or who are more concerned with trapping dust and dirt.

  • What causes a central air unit not to cool?

There are many possible reasons that an air unit is not cooling. You can perform several checks yourself before calling in a professional: check to see if the filter needs to be changed, check the outdoor unit to make sure it does not need cleaning, and check the thermostat and make sure it is on auto and not in the ‘on’ position. Also, make sure the circuit breaker did not trip. If none of these seem to be the problem, it may be best to call a professional.

  • Can a dirty air filter cause a high electric bill?

A dirty filter can make it more difficult for your unit to operate and cool correctly. Therefore, it has to work harder and run longer to reach the temperature you want. This creates a higher electric bill.
