How much does AC coil replacement cost

The more technical term for AC coil is evaporator coil. While how it works is a bit complex, its task is really simple: to keep the temperature inside your room cool.

So if your air conditioner isn’t blowing cool air, chances are your evaporator coil is worn or damaged. And you’d therefore need to replace it so you can feel fresh and comfortable again soon.

In this guide, we’ll tackle how much AC coil replacement costs, the factors that can affect it, and if DIY repair is a good idea.

The Cost of Replacing Your AC Coil

The Cost of Replacing Your AC Coil

Replacing your AC coil with a new one differs in costs mainly based on your air conditioner size. The heavier or bigger your AC is, the higher you will spend.

In general, an evaporator coil can be bought from $600 to $2,000. Here are the AC coil prices for their respective air conditioner sizes.

2 tons$550
2.5 tons$675
3 tons$825
3.5 tons$925
4 tons$1,000
5 tons$1,075

Note that this price range is only for the coil unit and you have to typically shell out an additional $700 for labor.

Factors Affecting the Price of AC Coil Replacement

Factors Affecting the Price of AC Coil Replacement

Besides your air conditioning size, other factors can push up the service price. These include the evaporator coil brand, labor, and ease of access.

Let’s explore them a bit below:

  • Brand

Of course, it’s best to get an evaporator coil that’s manufactured by the same company. This ensures peak performance and efficiency for your AC.

However, this isn’t always possible since the coil may be unavailable in your area. But the good news is that there are lots of brands you can go for out there that sells for a competitive price!

Prices for them range from $100 to $475. Among the lower-end brands are Aspen, ADP, and Bryant, whereas higher-end ones are Rheem, Carrier, and Lennox, to name a few.

  • Labor

We mentioned earlier that the average cost of labor for AC coil replacement is $700. But the cost can vary from $400 to $1,000 depending on your chosen contractor.

As you may notice, it costs more or less like getting an AC coil unit. That’s because the tradesmen need a license to carefully handle the refrigerant.

  • Ease of Access

Ease of access to your air conditioner also matters. If it is fairly easy to install the new AC coil, then you won’t have to pay extra for this.

Having said that, if the technician has to bring in special tools to get to your unit or if the process is complicated, the cost of repairing your air conditioner will be higher.

  • Other Old or Damaged Parts

As it often happens, your AC coil may not be the only part that needs replacing. Other parts like the motor, relay switch, and control board may need to be changed as well.

Here are the typical prices of these parts:

Relay switch$225
Control board$275

Fixing AC Coil by Yourself

Well, first you need to be a licensed refrigerant handler to be able to repair your AC legally.

That’s because refrigerants are harmful chemical compounds that can cause serious health conditions if you are exposed to them or have touched them.

As such, it’s always best to leave this work to an HVAC professional. As not only will you be safe, but you can also enjoy your cool restored air conditioner sooner.
