Signs You Need Professional Evaporator Coil Cleaning
- Reduced cooling capabilities
- Frost on coils
- Takes longer to cool down
- Musty smell
- Higher utility bills
Evaporator coils are an essential part of a functioning air conditioning machine. Air conditioners use a fan to blow air over metal coils filled with refrigerant. The refrigerant inside the coils cools the air as it blows over.
When the AC evaporator coils become too dirty, it is difficult for the air conditioner to function correctly. In this blog post, HVAC experts discuss three warning signs that air conditioner coils need to be cleaned.
Evaporator coil cleaning can improve the efficiency of the air conditioner. This helps the AC cool the house faster while using less energy. Keeping the evaporator coils clean also lengthens the lifespan of the air conditioning unit and prevents corrosion.
Reduced Cooling Capabilities
The evaporator coils, condenser coils, and other air conditioning components must work together to cool the air for the home. When the coils get too dirty, there can be a significant loss of cooling function. Evaporator coil cleaning can lead to immediate improvements in cooling performance.

Frost On AC Coils
One of the obvious visual signs of dirty evaporator coils that homeowners may notice is frost forming on the AC. The reason why ice and frost form on AC units is that dirty evaporator coils can affect the temperature of the refrigerant. The condensation freezes over on the coils when the refrigerant temperature drops too low.Frost on the AC coils is a bad sign. The ice on the evaporator coils can reduce cooling capabilities and prevent the air conditioner from working. Homeowners should get in contact with a local HVAC specialist when they first notice signs of frozen evaporator coils. The problem can worsen over time as dirty coils can begin to corrode.
Takes Longer to Cool Down
The air conditioner will run for longer cycles when it cannot cool the home efficiently. It takes more time to cool down the house when the AC is struggling with reduced cooling capabilities due to dirty AC coils. Homeowners may notice that it seems like their air conditioners are always running.
The system running for longer cycles is bad for multiple reasons. The longer the cycle, the more energy the air conditioner consumes, and the higher the power bill may be at the end of the month. It also reduces the air conditioning system's lifespan by placing unnecessary wear and tear on the parts.
