What Does an Evaporator Coil do in my AC System?

An evaporator coil plays an important role within an air conditioning system. It acts as a heat exchanger by subtracting the hot air within a home and transferring it to the exterior condenser unit, which cools the air inside a home.

During the heat extracting process, the evaporator coil also works to simultaneously dehumidify the air, making it easier for you to breathe and relax in your home.

Running through the evaporator coil are coolants such as Freon or Puron. Puron is composed of newer elements and is more energy efficient than Freon. You can typically find Puron in all new installed systems. Choosing Puron coolant might even save you more money on your utility bills.

As these coolants move through the evaporator coil (typically made of copper), they evaporate, drawing hot air into the coil and transferring it outside.

Common Issues with Evaporator Coils

Dust and Dirty Build-Up: As natural household dirt, dust and debris collects on the evaporator coil, it creates a buffer between warm air and the coolant within the coils. You may notice your AC system is not producing cool air anymore. If you smoke inside your home, tobacco smoke can increase the debris build-up on the evaporator coil.
Blocked Drain Causes Leaking: On hot days, the evaporator coils carry condensation droplets. Normally these water droplets collect into the pan and drain way. A clogged drain can cause the pan to overflow and leak water.
Frozen Coils: While it might seem odd that your evaporator coils can freeze even when it’s not cold outside, the coolant has a different freezing point than water. Frozen coils don’t produce cooler air — instead the frozen state prevents the coils from properly transferring heat to the outside of your home.
Cracked Coils: Cracks in, on or around the evaporator coils can cause them to malfunction, causing the unit to not properly cool your home.
Evaporator Coil Leak: If you notice refrigerant pooling at the base of the indoor parts of your AC system, you may have an evaporator coil leak.
General Wear and Tear: Just like other household appliances that work to keep you and your home at its peak functionality, over time the evaporator coil can become run down. Your AC may begin making loud usual noises, blow hot air instead of cold air or cycle on and off frequently.

How Right Now Gets It Done

Evaporator Coil Services in Boise, Idaho FAQs

What does an evaporator coil do in an air conditioning system?

The evaporator coil is a key component of an air conditioning system that absorbs heat from indoor air. As warm air passes over the coil, refrigerant inside absorbs the heat, cooling the air before it circulates back through the home. If the coil becomes dirty or damaged, the system cannot cool efficiently.

What are the signs of a bad evaporator coil?

Common signs of evaporator coil problems include warm air from vents, weak airflow, frequent system cycling, ice buildup on refrigerant lines or the indoor unit, unusual hissing noises that may indicate a refrigerant leak, and rising energy bills. Prompt service can help prevent further system damage.

Can a dirty evaporator coil affect energy efficiency?

Yes. A dirty evaporator coil restricts heat transfer, forcing the air conditioner to run longer to cool the home. This increases energy consumption and puts additional strain on the system. Professional cleaning can restore efficiency and improve cooling performance.

How often should an evaporator coil be cleaned?

Evaporator coils should be inspected annually during routine AC maintenance. Professional cleaning is typically recommended every one to two years, depending on indoor air quality, pets, and filter maintenance habits.

Can an evaporator coil be repaired, or does it need replacement?

Minor issues such as surface dirt or small leaks may be repairable, but significant corrosion, refrigerant leaks, or damage often require replacement. A professional inspection can determine the most cost-effective and reliable solution.
