Your AC’s evaporator coil plays a vital role in a comfortable summer. As part of the indoor unit, it’s responsible for regulating temperatures inside your home. When something goes wrong with this component, it can cause a variety of issues that may require some deep HVAC troubleshooting. Here’s a closer look at this part and when to contact an air conditioning contractor to replace it.

The Role of the Evaporator Coil

In simplest terms, evaporator coils are designed to absorb the heat inside your home along with humidity in the air. When the coil is compromised in some way, the air conditioner can’t efficiently cool down the house.

Inside the coil is refrigerant, a cold substance that pulls the heat and moisture away from your home. Then it travels to the outdoor unit, where the absorbed heat is dispersed to the outside air. 

Key Reasons to Replace It

If the evaporator fails, you may notice that there’s very little cool air blowing throughout the home. That’s usually reason enough to contact an air conditioning contractor, but you should also be concerned if you detect an unusually sweet odor when you run the AC. This occurs when the refrigerant in the coil leaks.

Leaks can occur over time, usually because a coil is corroded due to constant exposure to the refrigerant. The weaker the coil, the more likely it is to lose its integrity and fail, eventually causing the fluid inside to seep out.

When to Replace Instead of Repair

While you may want your air conditioning contractor to repair the problem, it’s usually more efficient and cost-effective to replace the evaporator coil entirely than to patch a leak and recharge the refrigerant.

In some cases, your technician may recommend replacing the entire AC if it’s especially old. In that case, investing in a replacement coil may not be an efficient step because the AC may not last for much longer.
