Troubleshooting Evaporator Coil Issues: Tips and Tricks for Homeowners


If you’re experiencing problems with your air conditioner, it may be due to issues with the evaporator coil. The evaporator coil is a vital component of your AC system that helps cool and dehumidify the air in your home. If there are problems with the evaporator coil, it can lead to decreased cooling efficiency and even complete system failure. Here are some tips and tricks for handling evaporator coil repair:

Check the Air Filter

The air filter traps dust, dirt, and other contaminants from entering your AC system. Over time, it can become clogged and restrict airflow to the evaporator coil. This can cause the coil to freeze up or not function properly. Regularly check and replace your air filter to prevent issues with the evaporator coil.

Remove Debris

The evaporator coil is inside the air handler unit, typically in the attic or basement. It’s important to keep this area clean and free of debris to ensure proper airflow to the coil. If there’s excessive dirt or dust buildup, it can also cause freezing and decreased cooling efficiency. Regularly vacuum or sweep around the air handler unit to prevent any issues with the evaporator coil.

Check for Refrigerant Leaks

Refrigerant is the substance that helps absorb heat from your home’s air and cools it down. If there’s a leak in the refrigerant line, it can cause problems with the evaporator coil, such as freezing or decreased cooling efficiency. If you suspect a refrigerant leak, it’s best to call a professional HVAC technician to inspect and repair the issue.

Clean the Coil

Over time, the evaporator coil can accumulate dirt, dust, and other debris, which can affect its performance. It’s recommended to have your evaporator coil professionally cleaned at least once a year. This will help improve its efficiency and prevent potential issues that may arise from a dirty coil.

Monitor Humidity Levels

High humidity levels can also cause problems with the evaporator coil. If there’s too much moisture in the air, it can lead to excess condensation on the coil, which can result in freezing or decreased cooling efficiency. Consider using a dehumidifier if your home consistently has high humidity levels.

Inspect for Bent Fins

The fins on the evaporator coil help with heat transfer and airflow. Over time, they can become bent or damaged, which can cause issues with cooling efficiency. It’s important to regularly inspect the fins and straighten them if necessary to ensure the proper functioning of the evaporator coil.

Remember that some troubleshooting tips may require the assistance of a professional HVAC technician. If you’re unsure or uncomfortable with performing any maintenance or repairs, it’s best to leave it to the experts to avoid causing further damage. Book a service today!
