An air conditioner is designed to cool your house, but it is not to designed to cool your house until it freezes up. If you notice that the outside of your unit or the interior coils have frost or ice built up on them, then you are dealing with a freezing issue. As a homeowner, it is a good idea to not only check for this issue regularly but to also understand what causes this particular problem and how to remedy the situation. Keep reading to learn more.
One of the most common reasons an air conditioning unit will freeze is because the air filter is dirty or clogged up. Therefore, you should check the air filter and see if it needs to be cleaned or replaced. By ensuring the filter remains clean, you can help ensure the flow of air is not restricted and the AC unit continues to run smoothly year-round.
Restricted Air Flow
A dirty filter is not the only reason there may be restricted air flow. Once you inspect the air filter, take the time to check the supply registers and return grilles to ensure they are not dirty themselves, closed, or obstructed in any way.
If your thermostat is set to a low temperature, particularly over an extended time period, it is possible for the air conditioning unit to freeze up. If this happens to you, you will want to adjust the thermostat to a more moderate temperature.
Dirty Evaporator Coil
Over time, the evaporator coil can accumulate dirt and debris. When this happens, problems can arise. Ultimately, the best thing to do is have the system inspected and cleaned on a regular basis, which will ensure that the evaporator coil is cleaned regularly. However, if the coil gets dirty in between having preventative cleanings, a professional will need to be contacted.
Your system may be freezing as a result of a refrigerant leak. There can be an assortment of reasons that you have a leak, including issues with the fittings, valves, and joints. Regardless of what is causing the refrigerant leak, it is an issue that will require the attention of an HVAC professional. Depending on the age of your air conditioning system and the extent of the issue, repair may not be the best course of action. Instead, it may be recommended for you to replace your system.
