How Much Does AC Evaporator Coil Replacement Cost? [2025 Data]

Evaporator Coil Replacement Cost Breakdown

Beyond the size of the unit, you also need to consider labor costs, ease of access, and the brand of the evaporator coil to determine the total evaporator coil replacement cost. You should also prepare yourself in case the AC repair company tells you other things need fixing, which will increase the cost.

Evaporator Coil Cost by Unit Size

AC units differ in size from household to household. While you may have a 3-ton unit outside your home, your neighbor may be rocking a window unit. This is why some people pay as little as $550 for their evaporator coil replacement, and others pay closer to $2,000.

This cost is only for the unit replacement and does not include labor. Labor costs around $700 on average. If your unit doesn’t state how big it is, you should contact your local air conditioning repair company to help you figure it out.

Labor Cost

Labor for an evaporator coil replacement costs anywhere from $400 to $1,000 depending on the job and service area. Labor tends to cost around the same as the evaporator coil itself because you need a license to handle refrigerant. Refrigerant is a serious chemical compound you don’t want on your skin.

Ease of Access

Where the unit resides in your home makes a difference in cost. In most cases, a unit is an accessible place that makes repairs easy. But if the unit is older or doesn’t make it easy to work in, expect to pay more in per hour labor costs, as the AC repair person needs to shimmy into a tight fit and may need to disassemble more of the unit.

Cost by Style

There are three main types of evaporator coils: A-coils, N- or Z-coils, and slab units.

Additional Costs 

The complement to the inside evaporator coil is the condenser coil. The condenser coil cools the gas the evaporator creates and turns it back into a liquid. They tend to have the same life span, so if your evaporator is on its last leg, you may want to check out your condenser as well. An AC condenser coil replacement costs around $800.

AC Repairs

If you’re particularly unlucky and run into a host of problems at once, there are other common HVAC replacements you may need to invest in.

• Replacing a blower motor costs $475 on average.

• Replacing an AC or furnace control board costs $275 on average.

• Installing a new relay switch costs $225 on average.

Warranty

If your unit is still pretty new, you may be able to get your repairs covered completely under your warranty. Time to pull that warranty page out of the back of the file box or go searching in your emails. Keep in mind that you may have to work with a specific company if you want your repairs covered under warranty, so read wisely. 

SEER Rating

SEER stands for Seasonal Energy Efficiency Ratio (or Seasonal Energy Efficiency Rating) and measures how efficiently your HVAC unit can cool your home. The higher the number, the more efficient the system (and the more you save on electric bills). However, parts and units with higher SEER ratings also come at a higher upfront cost. Just a one-point jump in SEER could mean a $2,000 difference.
