Common Problems With Evaporator Coils on AC Units and How To Fix Them

Evaporator coils are an essential part of air conditioning units that play a significant role in the cooling process. Unfortunately, these coils can suffer from common problems that can cause your AC unit to run inefficiently or not at all. But the good news is that there are simple solutions for fixing these issues. This article will explore the common problems associated with evaporator coils on AC units and how to fix them. Keep reading to find out more.

What are evaporator coils?

The evaporator coil is essential to any air conditioner or heat pump system. The evaporator coil on AC unit is the part of the system that cools the air in the home. It’s located inside the air handler and works with the condenser to regulate the temperature in the house. The evaporator coil is filled with refrigerant, a liquid that absorbs heat and transfers it to the outside air. As air passes over the coil, it absorbs the heat from the refrigerant, and then it’s cooled and redistributed throughout the home.

Evaporator coils are a vital part of the system because they help to cool the air inside the home. They also serve to eliminate moisture from the air to prevent the growth of mold and mildew. Without the evaporator coil, the air would also not be cooled. The evaporator coil must be maintained and cleaned regularly for an air conditioner or heat pump system to work correctly. If the coil becomes dirty or clogged, it will reduce the system’s efficiency and even cause it to break down.

What are the most common issues with evaporator coils on AC units

The most common issues with evaporator coils include leaking refrigerant, dirt buildup on the fins, frozen evaporator coil surfaces, and restricted airflow due to clogged filter systems.

Leaking refrigerants can stem from damaged seals around your system’s valves or compressor connections, allowing coolants to escape into other areas of your home’s ductwork. To fix this problem, you must first identify where these leaks are located by using leak detection tools such as infrared cameras or pressure gauges before replacing any faulty parts and recharging your AC unit with new refrigerants according to the manufacturer’s instructions.

Dirt buildup on finned surfaces is another issue that can occur when debris accumulates over time, blocking airflow through the coil surface area and resulting in reduced efficiency and higher energy costs. This problem should be addressed promptly by carefully cleaning out all dust particles using a soft-bristled brush dipped in water while avoiding damage to any delicate tubing inside the system housing itself; afterward, ensure sufficient drainage exists so no further buildups occur going forward.

Frozen evaporators may also affect performance if condensation freezes up on its surface, hindering proper evaporation from occurring during operation. This prevents evaporators from adequately cooling down warmer incoming air temperatures correctly, leading to inefficient running conditions overall. This issue requires immediate attention before permanent damage occurs, as thawing out these components will require additional time beyond just normal repairs alone, depending upon severity level.

It’s essential to have your evaporator coil inspected and cleaned at least once a year to ensure it’s working properly. If the coil is not properly maintained, it can cause the air conditioner to become inefficient and may even lead to costly repairs.

Overall, common problems with evaporator coils on AC units can be serious and costly. However, these problems can be fixed and avoided with the right knowledge and maintenance. Regular maintenance of the evaporator coils is essential for avoiding expensive repairs and keeping your AC unit running at its best.
