Residential AC Evaporator Coil Replacement Cost

Replacing a home air conditioner’s evaporator coil costs $1,000 on average with a typical range of $600 to $2,000. About 40% of the bill comes from labor, or $400 to $1,000. Warranties range from 5 to 12 years and cover the price of materials. Prices fluctuate based on the brand you own and your regional cost of living differences.

The evaporator coil collects heat from the air inside your home as the refrigerant in the lines evaporates from a liquid to a gas. It’s blown outside to the condenser coil to release the heat outdoors and repeat the process. For units with a heat pump, the heat simply travels the opposite direction (from outside in) using the same process.

Evaporator vs. Condenser Coil Prices

Condenser coils tend to cost 20% to 30% more than an evaporative style. But it depends heavily on the type and brand you get. Some evaporative types can match or exceed similarly sized condensers.

These are the two main components of your AC system and have slightly different costs. Including labor and parts, the run:

AC Coil Leak Repair Cost

Repairing a coil leak costs $250 to $1,600 or more. It’s about the same as simply replacing the entire part. Sometimes, you might only have to spend a couple hundred more to replace the entire unit. If you find a leak, discuss your options with your HVAC pro.

Average Cost to Replace Home Evaporator Coil by Style

The cost to replace your evaporator coil runs an average of $1,200. You’ll find three main styles:

  • A-coils simply looks like a tent. It’s got two pieces in a triangle shape. Most homes have this.
  • N-coils cost 15%-25% more for the same size of “A” or Slab types.
  • Slab units are flat and used in horizontal units that don’t take up much space.

Residential Evaporator Coil Replacement Cost by Brand

Carrier$400-$1,300
Trane / American Standard$200-$1,300
Goodman / Amana$250-$900
Lennox$200-$2,000
ADP$200-$1,000
Rheem / Ruud$300-$1,300
Bryant$250-$1,000
TempStar$200-$1,100
Aspen$250-$700
York$250-$1,200
Payne$250-$1,000

Although many of these companies share ownership, such as Rheem and Ruud, it’s important to match your brand and model exactly when buying a new part. Mismatched brands can lead to lower cooling efficiency and sometimes early failure.

Cased vs. Uncased Evaporator Coil Prices

Cased coils run anywhere from 25% to 75% more than uncased types.

  • Uncased: $200-$1,400. Come without a case of any type so they must fit within the current setup or need a modification to fit.
  • Cased: $350-$1,750. Come with a pre-fit case to keep air flowing through and not around the coolant pipes. Easier to install but higher upfront price.

DIY or Hire an HVAC Professional?

You should always hire a professional to replace the coil. Not only do you need a license to handle refrigerant, but most warranty replacements require the use of a licensed HVAC professional. If you install the wrong type or in the wrong configuration, at the very least you’re looking at an inefficient system. At the worst, you might end up with a $1,000 paperweight.
