When Your Home Is Humid, An Air Conditioning System Failure Could Be To Blame
On a hot day, a steady flow of cool, dry air from the air conditioning system is usually what people need to stay comfortable. So, when the air is cool but humid, the air conditioning unit will fall short of accomplishing this goal. As you might imagine, moist air blowing from a cooling unit is an indication that something is wrong.
Evaporator Coils
As the name suggests, the primary purpose of the evaporator coils is to remove excess moisture. During the cooling process, the heat and moisture from the uncooled air that passes around these coils are essentially absorbed by the evaporator coils. However, sometimes these coils can freeze.
In a frozen state, the evaporator coils will be unable to absorb the heat and moisture. As a result, the moisture-rich air would be sent directly into your home. If your evaporator coils are frozen, the air that flows through your home will likely also not be cooled, so you will have two issues on your hand.
Condenser Coils
The condenser coils play a similar role in the cooling process—they are also used to absorb heat and moisture from the air, which is then released outside your home. Over time, it is not uncommon for these fixtures to collect dust on their surface.
In short, when the coils are dirty, their ability to absorb efficiently is reduced. Since these coils cannot absorb heat and moisture, it also means that they cannot release them outside, so the inside of your home will likely become hot and humid. A repair technician can correct the issue, but regular maintenance can also help reduce this dust buildup.
Thermostat Sensor
The thermostat is basically an on/off sensor for the air conditioning unit. With cooling, when the temperature increases above the setting, the unit will kick in to lower the temperature. A part of this cooling process also involves removing excess moisture from the air.
For this reason, if the thermostat is not working correctly, the unit may not power on when necessary. This problem could mean that you have more warm, moisture-rich air circulating through your home. In this case, the temperature sensor must be repaired or replaced.
Contact an air conditioning repair professional if you have this issue to restore comfort in your home. Whether it is one of the listed issues or something else, a professional technician can help resolve the problem.
