As long as your air conditioner is working, you might not think about the coils in your unit at all. However, the coils may freeze without the proper maintenance, which will then render your A/C unit useless until it can be repaired. Here are some things you can do to make sure your coils are able to function without freezing up.
Brush the Coils
One of the best things you can do to make sure your coils and air conditioning unit work well is to brush the dust and dirt off of the coils on a regular basis. This is a relatively simple task that must be done so that the dirt on the coils doesn't cause them to work less efficiently and prematurely fail, causing them to freeze over.
To do this, unplug the air conditioner and use a hard-bristle brush or an old toothbrush to brush the coils and make sure there is no dust or dirt caking up.
The refrigerant in your air conditioning unit cools the air before it travels into your home. If there is no more refrigerant, the pressure inside the unit steadily drops until the coils freeze.
Therefore, it is a good idea to check the level of refrigerant in your unit on a regular basis. Usually the only time there is a problem is when there is a leak somewhere in the system that needs to be repaired.
Clean the Air Filter
The air filter on your unit traps dust and other particles so that you aren't breathing in dirty air. Over time, this filter will need to be checked. However, many people just ignore or forget about the filter. As a result, the filter becomes clogged and causes the entire unit to function less efficiently. Air cannot move effectively, which can cause the coils to become frozen.
To keep air circulation working properly, take steps to check and clean the filter as necessary. If you notice it needs to be replaced due to tears or holes, head to a home improvement store and get a replacement filter for the unit.
Be sure that you use the tips in this article to keep your coils from freezing up on you. If you need help or want a professional assessment of your entire air conditioning system, contact a local HVAC contractor who can offer you A/C service on a regular basis if necessary.
