High humidity makes a home uncomfortable. This is because it reduces the human body's ability to get rid of heat. It also creates a conducive environment for dust mite infestation and mold growth, something that then increases the risks of allergic reactions in loved ones. To prevent these negative effects of high humidity, taking measures to keep the humidity levels in your home under control is a must.
As it turns out, something as simple as cleaning your air conditioner filters can go a long way towards helping you do this. Here is what you should know about the relationship between your air conditioning system's filters and humidity control.
Clogged air filters and coil icing
When dirt accumulates on an air filter, it clogs it. This reduces the rate at which warm air passes through the filters. This is a problem since all the air that enters an air conditioner has to pass through the filters. As a result, clogging essentially starves the entire air conditioning system of the incoming air.
The evaporator coil is one of the parts of an air conditioning system that is affected by this air starvation. This is because it essentially depends on incoming warm air to balance off the cooling effect created by the evaporating refrigerant. Having less of the warm air in this area usually leads to a drastic drop in temperatures, something that then causes a layer of ice to form over the evaporator coils.
Coil icing and reduced condensation
The layer of ice that forms over the evaporator coils has insulating properties. It will therefore reduce the rate at which heat is transferred from the passing air to the refrigerant. This eventually leads to a drop in the efficiency with which the air conditioner cools the air.
As a result, any air leaving the evaporator coil won't be as cool as it should be. This is a problem since the air conditioning system usually relies on this cooling process to both reduce the air's moisture-carrying capacity and trigger condensation. The air being dumped into the home will therefore have more moisture than necessary, leading to less-than-desirable humidity levels.
Cleaning your filters to boost the system's humidity control capacity
To prevent coil icing that results from restricted air flow, it is advisable that you regularly clean your air filters. To do this, use a vacuum cleaner to suck any grime and dust particles from the surface of the filters. After you are done, soak them in a water-vinegar solution for a couple of hours before airing them to dry. Doing so will not only get rid of the airflow obstructions, but also discourage growths such as mold from developing on the filters. It will ensure adequate air flow within your air conditioning system and hence reduce the risks of reduced humidity control that results from coil icing.
