From one homeowner to another
Manny was very trustworthy and professional. He gave me a very fair price. Within 24 hours he had done his inspection and given me an estimate. It's the first time I talked to an HVAC company that didn't make me feel like I was getting overcharged. One of the other companies I spoke to was trying to charge 6 times the cost. He took lots of pictures and video and explained step by step what was done wrong by the other contractors and what he would need to do to fix it. He was able to do the work the day after I accepted the estimate. He completed all the work in one day. I am confident and very relieved to say that my HVAC system is set up properly.

Evaporator Coil Cost by Unit Size
Evaporator coil replacement costs range from $550 to $2,000, depending on your AC unit's size, making unit size one of the biggest drivers of price. Labor adds around $700 on average on top of the coil cost itself, and if you are unsure of your unit's size, a local air conditioning repair company can help you identify it. Costs vary by unit size as shown below.
| Unit Size | Average Cost in 2026 |
|---|---|
| 2 ton | $550 |
| 2.5 ton | $700 |
| 3 ton | $850 |
| 3.5 ton | $950 |
| 4 ton | $1,000 |
| 5 ton | $1,100 |
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 runs $400 to $1,000 depending on the job and your service area. Because handling refrigerant requires a license, labor rates tend to run close to the cost of the coil itself, and working with this chemical compound without proper training poses a genuine safety risk.
Ease of Access
Where your unit is located in your home directly affects what you pay for labor. When a unit is easy to reach, repairs stay straightforward, but a unit in a tight or awkward space requires the technician to work harder and potentially disassemble more components, which drives up per-hour labor costs.
Evaporator Coil Cost: By Style
The style of evaporator coil your system uses is another key cost factor, with three main types available: A-coils, N- or Z-coils, and slab units. Costs vary by coil style as the breakdown below shows.
| Coil Type | Description | Average Cost in 2026 |
|---|---|---|
| A-coil | Space-efficient design, optimizes heat exchange | $1,300 |
| N- or Z-coil | Improved overall system performance | $1,550 |
| Slab unit | Compact and perfect for smaller spaces | $1,200 |
| Uncased | Simplest installation | $800 |
| Cased | Good for highly customized areas or smaller spaces | $1,000 |
Evaporator Coil Additional Costs: What to Budget For
When budgeting for an evaporator coil replacement, factor in the condenser coil as well, since the two components share a similar lifespan, and an AC condenser coil replacement costs around $800. The condenser coil cools the gas the evaporator creates and converts it back into a liquid, so if your evaporator is failing, it is worth having a technician inspect the condenser at the same time.
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 AC unit is relatively new, your warranty may cover the evaporator coil replacement entirely, so it is worth locating your warranty documentation before scheduling any repairs. Read the terms carefully, since many warranties require you to work with a specific service provider to keep coverage valid.
SEER Rating
SEER, which stands for Seasonal Energy Efficiency Ratio, measures how efficiently your HVAC unit cools your home, and a higher rating means lower electric bills over time. Parts and units with higher SEER ratings carry a steeper upfront price, and a single one-point jump in SEER can translate to a $2,000 difference in cost.
Why You Should Hire an Evaporator Coil Replacement Pro
