Common Problems That Occurs Due To Dirty Evaporator Coils

You must properly maintain air conditioning units to operate efficiently and last a long period of time. A condenser coil is an important component of an air conditioner. The condenser plays an essential role in the cooling process by condensing the refrigerant and removing heat from the air. 

Regular operation will cause this coil to gather dirt and grime, which will diminish the unit’s performance in the long run. If the condenser coil on your air conditioner is dirty, you can experience various problems. Get in touch with a professional for HVAC installation in Garden Grove.

Why Is Proper Maintenance Important?

An AC with a dirty condenser coil may also lose some cooling ability. Having a dirty condenser coil can lead to a less effective cooling system because it can transfer less heat to the outside air. An AC with a dirty condenser coil may not be able to provide adequate cooling to a structure. 

It may take much longer to achieve the desired cooling in some cases. An average person can clean the outside of the coil, but that is only half the job. Ensure that the condenser coil is clean and free of obstructions by hiring an AC contractor in Garden Grove, CAwith the right equipment and skills. 

An HVAC technician should inspect and clean the entire air conditioner unit annually, including the condenser coil. The technician will inspect all the parts to ensure that they are functioning properly and in good condition. It will help ensure the unit has a long operating life if it receives an annual inspection and cleaning.

Dirty Evaporator Coils: Problems

  • Insufficient Cooling

How has the temperature of the air coming out of the vents changed? In cases of coil buildup, the air conditioner might still turn on, but it won’t perform well. 

Dirt is a barrier to the air, and the metal coils cannot absorb enough heat circulating in the house and through the vents. This way, you can significantly reduce the cooling process.

  • AC is Constantly Running

The thermostat monitors the temperature in your home and communicates to the air conditioner when to turn on. Sounds easy. As it runs in cycles, it can be a problem if the evaporator coil is dirty. 

It keeps running endlessly, trying to do its job – and tiring itself out. The dirtier the coil, the longer the cycles. If this continues for too long, you can damage the whole system.

  • Coils Can Freeze

Your air conditioner’s coils are particularly vulnerable to freezing. What happens if they freeze? Condensation can build up on coils due to dirt buildup limiting the amount of heat it can absorb. 

Ice is then formed from this water. When this happens, your air conditioner can break down, causing you and your family unnecessary expenses and stress.
