Problems With a Dirty AC Evaporator Coil

May 30, 2024

The evaporator coil plays a crucial role in the performance of your AC system. When dirt and debris accumulate on this component, its efficiency reduces. Below, we will discuss signs of a dirty AC evaporator coil in Huntsville, AL.

High Levels of Indoor Humidity

The AC component that absorbs excessive humidity in your indoor air is the evaporator coil. After the coil absorbs the moisture, the moisture collects in a drain pan and makes its way outside through the drain line.

When the evaporator coil is too dirty, it struggles to absorb enough moisture. Consequently, this moisture remains in the indoor air, making your home uncomfortable.

Excessive moisture in your indoor air also allows biological growth to flourish in your home. These contaminants release spores that lower the indoor air quality; hence, you should have the coil cleaned as soon as possible to eliminate the moist environment that allows these pollutants to thrive.

Hot and Cold Spots in Your Home

The refrigerant draws heat from your indoor air at the evaporator coil. If there are impurities coating the evaporator coil, the refrigerant cannot draw enough heat from your indoor air. Since the system manages to cool only a small portion of your indoor air, your home ends up with inconsistent temperatures.

Your AC System Runs Constantly

Typically, your air conditioner stops working after achieving your temperature demands. However, a system with a clogged evaporator coil never stops running because it struggles to achieve the temperature you set on the thermostat.

Your System Has a Frozen Evaporator Coil

When the refrigerant fails to absorb enough heat from your indoor air, it remains cold. The evaporator coil also remains cold. These low temperatures make the moisture coating the evaporator coil freeze.

Having your evaporator coil cleaned regularly enables your system to maintain a comfortable indoor environment for your family. Call Sensigreen Heating, Cooling & Insulation whenever you need professional air conditioning services.
