Reasons Your Air Conditioner Causes Humidity


Nothing beats sitting in your recliner with the air conditioner running in the background on a hot, muggy summer evening. But there’s a catch. Yes, the temperature inside your home is slightly lower than outside. On the other hand, the air in your home feels just as sticky as the 80% humidity outside. Even if your air conditioner is working hard to keep your home cool, you may notice that the indoor humidity is rising. Does this sound like your house? If this is the case, AC humidity may be the source of the problem.

The Sources of Higher Humidity

One of the most common causes of increased humidity in your home is the installation of an air conditioner. Air conditioners are intended to remove moisture from the air, but if not correctly installed, they can add moisture to the atmosphere. Air conditioners that are too small for their rooms will run continuously, never getting a chance to remove all the moisture from the air.

ACs that are too large will cycle on and off so frequently that they will not have enough time to remove all the moisture from the air. That is why it is critical to have a professional AC installation company come out and assess your AC needs before installing your AC. They will be able to determine the proper size of the AC for your home and ensure that it is properly installed so that it does not cause higher humidity levels in your home. Other factors to consider when the humidity in your home rises.

  • The condensation on your AC coils is excessive. When coils get too cold, they can frost over, obstructing airflow and causing problems evaporating moisture from indoor air, resulting in higher humidity levels in your home.
  • The air conditioner is not properly draining. A small pan collects the condensation as the window air conditioner removes moisture from the air. A hose or tube is then used to drain the water. If this system becomes clogged, water will back into the unit, causing it to work inefficiently and increasing humidity levels.
  • Your ductwork leaks. If your ductwork has cracks or holes, humid outside air can leak in and mix with your home’s cooled air, raising overall humidity levels. A professional HVAC technician should repair any leaks as soon as possible.
  • The air conditioner filter needs to be changed. A clogged filter can restrict airflow and force the unit to work harder than it needs to, raising humidity levels. Check and replace your filter regularly.

The Best Indoor Humidity

Although humidity levels will vary depending on personal preferences, your home’s relative humidity is recommended to remain below 50% when outdoor temperatures exceed 50°F. Anything above 50% causes issues for you, your family, and your home. Dust mites and mold spores thrive in high-humidity environments, potentially causing family health issues. High humidity can also cause moisture to collect on windows, doors, and even your wood furniture. It can cause severe damage over time.
