The air conditioner evaporator coil is a critical component of your AC system, responsible for removing heat from the air and cooling your home. However, like any other part of your air conditioner, the evaporator coil is prone to wear and tear. In this article, we’ll discuss some of the most common issues that can arise with the evaporator coil and what you can do to address them.

Note: issues with the evaporator coil should not be taken lightly as it handles refrigerant and is one of the most expensive parts to replace in an air conditioner.

1. Dirty or Clogged Evaporator Coil

A dirty or clogged evaporator coil can cause your air conditioner to function less efficiently, leading to higher energy bills and reduced cooling performance. Eventually, this could lead to the AC unit running constantly or a complete system failure. If you notice that your AC system isn’t cooling your home as well as it used to, a dirty evaporator coil may be to blame.

2. Frozen Evaporator Coil

If your evaporator coil freezes over, your AC system will stop working altogether. This can occur if the coil becomes too dirty, if the refrigerant level is low, or if there’s an issue with the blower fan. To fix a frozen evaporator coil, you’ll need to turn off your AC system and let the coil thaw completely before calling a professional to diagnose the underlying cause of this freeze-up.

3. Corrosion or Leaks

Over time, the evaporator coil may develop leaks or corrode, leading to a loss of refrigerant and reduced cooling performance. If you suspect that your evaporator coil is leaking, you’ll need to have it replaced by a professional HVAC technician. A repair is almost never an option with evaporator coils. This should be taken care of as soon as possible; refrigerant is extremely dangerous and can lead to long-term health problems.

4. Improper Size

If your air conditioner’s evaporator coil is too small, it may not be able to cool your living space effectively. Conversely, if the coil is too large, it may cause your AC system to short cycle, leading to reduced efficiency and increased wear and tear. This issue only arises if your evaporator coil has been replaced and the wrong size was installed. You’ll need to have a professional HVAC technician recommend the appropriate size for your evaporator coil.

The evaporator coil is a critical component of your air conditioner, and any issues with it can lead to reduced cooling performance and increased energy bills. If you suspect your evaporator coil is dirty, frozen, leaking, or improperly sized, address the issue as soon as possible.
