Why is my house so humid?
Let’s take a look at some reasons why your home might be excessively humid: 1 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. 2 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.
