You should have your AC coils cleaned regularly by an AC repair pro to keep your air conditioning system running smoothly. Our guide will show you how much AC coil cleaning costs.

AC Coil Cleaning Cost Factors

Your air conditioning unit has two types of coils: condenser and evaporator coils. You should clean both AC coils at least once per year to prevent clogging and grime buildup. Your total AC coil cleaning cost comes down to several factors, including the type of coil, cleaning method, size of your AC unit, and labor. Here’s what you can expect to pay for AC coil cleaning:

Types

Your AC unit has two types of coils: condenser and evaporator. These coils tackle different sides of the cooling cycle in your AC system. Here’s what you can expect to pay to clean each coil:

Type of CoilAverage Cleaning Cost
Evaporator coil$100–$700
Condenser coil$75–$200

Cleaning Method

Your chosen AC coil cleaning method will also affect your total bill. Consult your AC repair pro to determine the best option for your system.

Cleaning MethodAverage Cost RangeDescription
Cleaning in place$100–$400A pro uses compressed air to clean coils without removing them
Removing and cleaning coils$400–$700Deep-cleaning method requiring a pro to remove coils and clean by hand
AC acid wash$300–$350Deepest clean where a pro removes coils and uses acid to immediately wash away stubborn buildup

AC Unit Size

There are 10 types of air conditioners that come in many shapes and sizes. Some are easier and faster to clean than others, causing prices to vary. For example, window AC units and portable air conditioners are easier to clean because they are smaller with more centrally located coils. However, you can anticipate paying more for cleaning central air conditioners, ductless mini-split units, and heat pumps because they use larger coils, which are more challenging to access. 

Labor

You can expect an AC repair pro to charge an average of $175 per hour or between $100 and $250 per hour for labor. Your total labor cost will depend on the condition and accessibility of your unit and coils. Shop around and get price quotes from at least three local AC professionals to find the best fit for your project.

How Often Should You Clean AC Coils? 

You should invest in AC coil cleaning at least once per year during your annual maintenance visit. If you live somewhere with a lot of foliage or air pollution or you’re near the coast, your pro may recommend more frequent cleaning of your outdoor coil (every six months or less). 

Cost of Common AC Coil Cleaning Add-Ons

While you’re having your AC coils cleaned, you might want to consider adding on an annual or bi-annual maintenance plan, along with other preventative measures, including:

DIY AC Coil Cleaning vs. Hiring a Pro

You can DIY coil cleaning yourself if you have prior professional experience working with AC units. You’ll save on labor costs, but you’ll need to purchase a fin cleaning brush ($5 to $25), a microfiber cloth, a coil cleaning solution ($5 to $20), and a vacuum hose attachment. However, working with AC units is a complex and potentially dangerous task, especially due to the risk of accidental damage to your system. 

That’s why we recommend hiring an AC repair company near you to ensure the job is done correctly, especially if your coils are extremely grimy and need professional cleaning. AC pros have the skills, tools, and experience to restore your coils to their best condition and complete the job efficiently and safely.

Frequently Asked Questions

Yes, AC coil cleaning is definitely worth it. Cleaning your AC coils ensures your AC unit will function efficiently for the long term. Dirty and grimy AC coils make your unit work harder to cool your home, resulting in higher electric bills. Additionally, having your coils professionally cleaned regularly will reduce the possibility of extensive maintenance and repair costs.

You should have your AC coils cleaned once per year. To keep your AC unit in tip-top shape, consider cleaning your coils twice yearly—before and after air conditioning season. That way, the pro will remove any dust, dirt, and debris that has built up over the winter and catch new grime that accumulated during the summer. Additionally, if you’re handy, you can tackle any in-between cleanings yourself with a special fin comb.

There are several tell-tale signs that your AC coils need cleaning, including:

  • You’re getting higher electricity bills.

  • Your home doesn’t feel as cool as it usually does.

  • Your AC unit is running longer than usual to cool your home.

  • Your home is more humid than usual.

  • The coil is covered in frost while running.

Here’s how AC professionals will clean your AC coils:

  1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

  2. Remove the faceplate.

  3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

  4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

  5. Use the vacuum hose to suck up any extra debris.

  6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

  7. Let the solution sit for at least 15 minutes.

  8. Gently wipe away loosened grime and debris with a microfiber cloth.

  9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.
