Why Is My AC Creating So Much Humidity?

High Humidity in Granite City, IL

An effective air conditioner is a necessity for hot summers. However, humidity caused by AC units is a major problem for homeowners. Many people who purchase a cooling system expect humidity levels to naturally be controlled by the stabilizing of air temperature. But, many AC units simply can’t achieve this.

An AC unit’s main function is to absorb heat from the indoors and transport it outside, naturally lowering the indoor air temperature. An air conditioner draws moisture from the air when it pulls thermal energy to its evaporator coils. Water that condenses around the coils because of this is ultimately pumped out through a drain upon being collected by the AC unit’s fan. In this way, the air conditioner actually acts as a dehumidifier. It’s usually when this process isn’t working correctly that humidity becomes a problem.

Reasons Your AC’s Natural Dehumidification Process Might Be Malfunctioning

The first thing to check when trying to determine why your air conditioning system is making your house so humid is whether or not the evaporator coils are frozen. If the coils are covered in frost, they not only can’t cool the air efficiently, but they also can’t dehumidify the air. This causes your home to become muggy at a rapid rate.

Second, check for any dust, dirt, and debris. An AC unit can only function properly when it’s clean. Although there should be a filter built into the air conditioner already, debris buildup over time can cause significant damage to the AC unit’s internal processes. When one aspect of its function is out of whack, it will more than likely affect other functions, including the ability of the system to pump water out of your house sufficiently.
