Note: This page covers repair, installation, and evaporator coil replacement cost for central air conditioner and heat pump systems only. It does not cover complete hvac systems, or components like a compressor or complete ac unit and coil.
Evaporator coils commonly fail sooner than almost any other component of a home HVAC system. While many will argue the reasoning for failure, everyone agrees that if you don’t properly clean and maintain your system every year, it will eventually result in a buildup of dust, soot and other airborne particles that will block air flow and lead to failure. While a properly maintained AC and evaporator coil will last 10-15 years or longer, an improperly cared for system could fail you as quickly as 1-3 years. In addition, not having the condensate drain line cleaned each year can result in water buildup, that will corrode the coil and increased failure rates as well as reducing the life of your furnace, if the coil drain pan overflows and drips into it.
This Costimate will help you estimate the cost of replacing the AC evaporator coil in your home cooling system. We’ll cover different types of coils for both central air and heat pump systems, as well as other work that may need to be done at the same time your coil is replaced. If you’ve already learned your evaporator coil has reached the end and your central air conditioner is more than 8 years old, you should consider comparing the cost of ac unit and coil replacement at the same time, since both components need to be matched for efficiency and proper operation.
Evaporator Coil Cost Factors
The evaporator coil is a key component in the operation of your central ac, and it must be matched to the outdoor condensing unit in both size (btu capacity) and refrigerant type. The factors below will have the greatest impact on cost of AC evaporator coil replacement.
The AC Brand, and Why it Affects the Cost of a Coil Replacement
The brand of your central ac unit has a large impact on the cost of just about any type of repair. In the case of an ac coil replacement for example, Goodman uses A-Coils (pictured above) on their central air systems, which are readily available, common in size and shape, and cheaper to manufacture. Carrier, Bryant and several others use an N-Coil design, which has more surface area and thus more costly to manufacture. The evaporator coils with Trane, American Standard and other leading brands are likely matched to your unit for efficiency requirements, so they may need to be more specific models than say a Goodman, York or more affordable brand.
While you’re not required to use a brand specific company to replace your out of warranty coil, you may be required to do with with a warranty replacement. Keep this in mind when you speak to a technician if your central air is still under warranty.
Cost of Installation Supplies
In addition to the coil itself, you may also have to incur these additional costs when replacing an evaporator coil.
Not every town requires a permit to replace the evaporator coil since its considered a repair, versus system replacement. If however, you were replacing the outdoor condensing unit or furnace at the same time, there is a much higher probability you would need a permit and inspection. Check with your local code enforcement office, or ask your contractor.
Permits and Inspection
Installation Cost and Time
Most evaporator coil replacement estimates will be based on a flat rate. If the coil is under warranty, the manufacturer will pay the cost of the coil itself, but you will still responsible for the labor costs for the contractor. In these cases, the contractor may charge hourly, versus flat rate.
Completed Installation Time
In many cases, the coil can be changed by one lead installer. However, in jobs where sheet metal work, additional furnace repairs or other factors complicate the repair, you will find 2. In almost every evaporator coil replacement I have been a part of, there were two workers who handled the job.
Evaporator coil replacement is a job best left to a professional heating and ac contractor. You might be able to handle the mechanical portion of removing and replacing the coil itself, but brazing, evacuating and reclaiming old refrigerant and charging the complete system and new coil with refrigerant all require special tools, skills and certifications.
Trying to save money by installing your own evaporator coil might be an attractive thought. Aside from buying all the right tools to do the job correctly, you could easily end up causing damage to the outside condensing unit, thus eliminating any savings at all. I’m a handy guy, and this is a pro job every time! There is a good walkthrough and discussion at Houzz on this topic.
