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 LeakingOn 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 CoilsWhile 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 CoilsCracks 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 TearJust 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.

F.A.Qs
Frequently Asked Questions
The evaporator coil is a critical component of your air conditioning system responsible for absorbing heat from indoor air. As warm air passes over the coil, refrigerant inside absorbs the heat, cooling the air before it circulates back through your home.
If the evaporator coil becomes dirty, frozen, or damaged, your AC system cannot cool effectively. Right Now Heating, Air Conditioning & Plumbing provides professional evaporator coil inspections, cleaning, repair, and replacement to restore system performance.
Common signs of evaporator coil problems include:
-
Warm air coming from vents
-
Weak airflow
-
Frequent system cycling
-
Ice buildup on refrigerant lines or the indoor unit
-
Unusual hissing noises (possible refrigerant leak)
-
Higher-than-normal energy bills
If you notice any of these issues, prompt service can prevent compressor damage and more costly repairs.
Yes. A dirty evaporator coil restricts heat transfer, forcing your air conditioner to run longer to reach the desired temperature. This increases energy consumption and system wear.
Professional coil cleaning from Right Now Heating, Air Conditioning & Plumbing helps restore efficiency, improve cooling performance, and lower monthly utility costs.
Evaporator coils should be inspected annually during routine AC maintenance. In most homes, professional cleaning is recommended every 1–2 years, depending on factors such as indoor air quality, pets, and filter maintenance.
Regular tune-ups help prevent dirt buildup that can lead to frozen coils and reduced system lifespan.
Minor issues such as surface dirt or small leaks may be repairable. However, significant refrigerant leaks, corrosion, or coil damage often require replacement.
Right Now Heating, Air Conditioning & Plumbing performs thorough diagnostics to determine the most cost-effective solution and provides transparent recommendations before any work begins.
The cost of evaporator coil replacement varies depending on system size, coil type, and warranty coverage. While it can be a significant repair, replacing a failing coil can restore cooling efficiency and prevent compressor failure—which is typically much more expensive.
Our team provides upfront pricing and financing options to help homeowners make informed decisions.
