Troubles You May Run Into With Your AC’s Refrigerant Coils


As the temperatures rise and summer approaches, your air conditioning system becomes essential for maintaining indoor comfort. Within your AC unit, one crucial component that plays a significant role in its performance is the refrigerant coil. These coils are responsible for transferring heat and helping to cool the air circulated throughout your home. However, like any other part of your HVAC system, refrigerant coils can encounter issues that affect their efficiency and functionality, often requiring AC repairs in Katy, TX.

In this blog post, we’ll delve into the troubles you may encounter with your AC’s refrigerant coils.

Understanding Refrigerant Coils

There are two main types of refrigerant coils: indoor coils located in the air handler unit and outdoor coils situated in the condenser unit. Both types play crucial roles in the cooling process, and any issues with these coils can affect the efficiency of your AC system. These coils are typically made of copper or aluminum tubing and are surrounded by thin aluminum fins. As refrigerant flows through the indoor coil, heat from the indoor air is absorbed, cooling the air before it is circulated back into your home. The outdoor coil then does the opposite job of releasing the heat.

Common Issues with Refrigerant Coils

Refrigerant Leaks

Refrigerant leaks are a common problem that can occur in AC systems, often leading to decreased cooling performance and higher energy bills. These leaks can be caused by factors such as corrosion or faulty installation. Signs of a refrigerant leak include reduced cooling capacity, hissing or bubbling noises, and ice buildup on the refrigerant lines or coils. Ignoring a refrigerant leak can lead to further damage to the compressor and other components of your AC system.

Coil Corrosion

Coil corrosion occurs when the metal components of the coils deteriorate due to exposure to moisture, chemicals, or pollutants in the air. Corrosion can weaken the coils and eventually lead to leaks or inefficiencies in heat transfer. Regular maintenance, such as cleaning the coils and changing air filters, can help prevent corrosion. However, if corrosion is detected, prompt action is necessary to prevent further damage.

Coil Freezing

Another common issue with refrigerant coils is freezing, which occurs when moisture in the air freezes on the surface of the coils. This can happen due to restricted airflow, low refrigerant levels, or dirty coils. Thawing a frozen coil and addressing the underlying cause is essential to prevent further damage to the AC system.

Importance of Timely Repairs and Maintenance

Addressing refrigerant coil issues promptly is crucial for maintaining the efficiency and longevity of your AC system. Ignoring these problems can lead to decreased cooling performance, higher energy bills, and costly repairs in the future. That’s why it’s essential to schedule regular maintenance checks with a professional HVAC technician to inspect and service your AC system.
