Things Causing High Humidity Levels In Your Home

Updated: Feb 10, 2023

Summer is a time for relaxation and basking in the sun. But when you tire of the heat, you will want nothing more than to retreat to your cool, air-conditioned home. But what happens when your cold house is no less humid than the outdoors? Learn four things causing excess humidity in your home here.

Humidity Level Shows on Sand

1. AC System Is Too Big or Too Small

An air conditioner that is too large for your home may cool it down too quickly, often turning on and off in short bursts, called “short cycling.” Not only can short cycling make your home feel humid, but it will increase your energy bills as well. Consider having an HVAC professional inspect your home’s air conditioning system to determine if it is improperly sized.

2. Frozen Evaporator Coils

Evaporators maintain a temperature below the dew point, causing air to condense on the coils. These coils accept cold, liquid refrigerants from outdoor units to cool and dehumidify the air. If frost covers the coils, they will fail to properly execute these duties, leading to excess condensation being released into the home. If you believe the evaporator coils in your HVAC system are freezing over, call a professional to diagnose and assess the issue.

If you feel confident cleaning the evaporator coils yourself, you can clean them with condensed air or a brush and a couple of minutes of your time.

If using condensed air:

– Point the compressed air across the coil in the opposite direction of the airflow. – For stubborn dirt and grime, place the compressed air nozzle near the bottom side of the debris. – Maintain a consistent airflow across the coil, which will help dislodge buildup without harming the fins.

If using a brush:

– Apply the brush to the coils and sweep dirt accumulations away. – Scrub with the brush to break loose harder-to-remove material. – Opt for soft-bristle brushes, so you don’t damage the fins.

3. Excess Dirt, Dust, and Debris In Your Home

For the same reason that frost is harmful to your cooling system, so is any grime that may accumulate on the machine’s more sensitive components over time. Regularly cleaning your air conditioner will help, but if the issue has become too severe, you may need to call an HVAC company to schedule a professional cleaning.

4. Poor Ventilation

Air barriers prevent air leakage between conditioned and unconditioned spaces. Uncontrolled air flow due to poor ventilation can prove counterproductive to the dehumidifying process, as well as a result in mold and rot. If air escapes from even a small hole in the walls or ceiling and touches a surface colder than 52° Fahrenheit, it will cool and eventually reach its full capacity for storing moisture. Therefore, condensation that causes humidity will appear.
