How Much Does an AC Coil Replacement Cost?

Owning an air conditioning unit means the inevitable reality of maintenance costs and AC condenser repair expenses. One of the most common expenses is the need to replace the coils within your AC unit. If you’ve found yourself in need of new coils, use this guide to get an idea of what they cost and what new coils mean for your AC unit.

How much does it cost to replace an AC evaporator coil?

AC evaporator coil costs can vary based on several factors. For the most part, customers can expect to spend anywhere from $700 to $3,000 on the replacement. This estimate includes the costs associated with both the parts and labor for a total average cost of around $1,500. When calculating the price, it can often change according to the size and type of unit you have. 

Do repair costs differ between HVAC types?

In short, yes they do. Similar to cars, AC evaporator coil repair costs can differ depending on the type of AC unit you have in your home. The components of a central air conditioning unit can be distinctly different from those of a ductless system. An AC condenser coil or evaporator coil repair cost is also going to change based on the manufacturer and where you buy it. 

Other factors influencing AC evaporator coil replacement cost

In addition to the type of system, there are a few other factors that can impact the cost of your coil replacement, including:

  • Unit size: The overall size of the unit has a direct impact on the total cost of installing new coils. Larger units require larger coils to get the job done effectively, which means a higher premium.

  • Labor: The experience of your technician can also impact the cost they assess when fixing your HVAC system. Additionally, costs may be inherently higher or lower depending on the state the business is located in.

  • Accessibility: Some costs get higher due to the accessibility of the unit. If your air conditioning system is not easily accessible, prices for working on it can increase. 

  • Brand: The brand of your air conditioner can also have more expensive components by default.

Benefits of replacing your AC evaporator coil

So, why should you replace your evaporator coils? For one, keeping up with the lifespan of your coils can extend the life of your air conditioner and help improve the overall energy efficiency of the unit. Additionally, when the coil is working as it should be, it puts less stress on the rest of the air conditioning components. 

When does an AC coil need to be replaced?

Several common reasons for an AC coil replacement can include leaks, signs of corrosion, and less-than-optimal performance. So, if you notice a leak or an unusual noise coming from your unit, chances are the coil may need some attention. 

Repairing vs replacing your AC evaporator coil

Determining whether or not to repair or replace the AC coils strongly depends on the severity of damage to the unit. For small leaks, a repair may be all that’s needed. For clear signs of corrosion or multiple leaks, it may be safest to replace the faulty component.

How long does an AC evaporator coil last?

The lifespan of your evaporator coil will depend on a few different factors. How often does the unit run? How frequently do you keep up with parts inspection and maintenance? What type of environment are you in? However, the average evaporator coil should last anywhere from 10 to 15 years, on average.

Hiring a pro vs DIY AC coil replacement

It’s a common question: should you hire a pro or DIY your AC repair job? Depending on your situation, here are some considerations to think about before making a decision:

DIY AC coil replacement

While DIY maintenance can save you on your AC evaporator coil repair costs, it takes technical knowledge and the proper set of tools. Inexperience could not only cause further damage, but it could also void existing warranties.

Professional AC coil replacement

While there’s more out-of-pocket costs, you can rest easy knowing the job was done well and done properly to prevent further issues down the line. 

What to look for when hiring a professional HVAC service

Looking for a technician? Verify that your technician is certified, has a positive reputation, and a number of good reviews. Having a warranty and providing detailed documentation are also things to look for when hiring a professional HVAC service

AC evaporator coil vs condenser coil replacement

Before making any changes, it’s important to know the type of coil that needs replacement. Below we’ve outlined the two primary types of coils:

AC evaporator coil

The evaporator coil is located inside the indoor unit of your AC system and absorbs heat from the indoor air. 

AC condenser coil

The AC condenser coil is located on the outside unit and rejects absorbed heat into the outside air.
