My AC is Running But My Home Feels Humid — What’s Wrong?

As you may already know, your AC functions like a dehumidifier as it cools. When this process is no longer working as well as it should, then you may experience high levels of humidity in your home, in addition to any other issues such as inadequate cooling or hot spots. This can lead to stuffy and uncomfortable air throughout your home. Call Premier Indoor Comfort Systems today if you’re concerned about the high levels of humidity in your home. We can arrive promptly at your home and assess what might be wrong with your air conditioning system.

Let’s take a look at some reasons why your home might be excessively humid:

  • Frozen evaporator coils:  When you have frost on your coils, it means that they are not able to perform their function. The evaporator accepts cold, liquid refrigerant from the outdoor unit and uses this is to cool the warm air that has been extracted from your home, and then return that cooled air to you. But your coils can’t cool the air if they are covered in frost. Your coils therefore will not dehumidify the air as much as they should, making your home seem muggy.
  • Dirt, dust, and other debris: As with any mechanical system, your AC needs to be kept clean at all times, but this is not always so straightforward. While there is an air filter near your air handler that minimizes the amount of dust, dirt and debris that can accumulate on sensitive components, over time, your system will nevertheless need to be professionally cleaned. In particular, your outdoor condenser coils are subject to environmental conditions, and if they are in any way impaired by dirt or other materials, it makes it difficult for them to dissipate heat into the outdoor air. This disrupts the refrigerant cycle, and can lead to higher temperatures and a lack of dehumidification.

However, keep in mind that your AC is not a dehumidifier. If you find that you have consistently high humidity levels in your home, then you need to take advantage of a whole-house dehumidifier. Call Premier Indoor Comfort Systems today for all of your Atlanta air conditioning needs.
