Why Is My Air Conditioner Freezing?
As is the case with Florida in the summer, the heat and humidity of the environment are extreme. With this, the most important thing, next to the electricity powering your home, will be your A/C unit, as anyone knows what a house is like without one running. But, you may notice that when the weather is at its worst is when your unit will give out on you, and freezes up. There are several reasons as to why this is happening, and we would like to go through a couple of reasons as to why.
If you’re A/C system is not functioning correctly, it may affect the refrigerant chlorodifluoromethane or R22, and how it behaves within the system. If the pressure in your system changes, then this could cause the R22 to behave differently. As the house’s moist air makes its way over the evaporator, the air’s moisture will condense and freeze on the system’s coils, and ice will form. This ice will act as an insulator and cause the coils to freeze, and not function. To fix this, you should contact Airsource America so a professional can come out and make the proper repairs.
Overused, or clogged up air filters will prevent air from making its way correctly through your unit. This reduction of airflow will lead to your group having to work harder than usual to complete the cooling you want it to. This prevents the right amount of warm air from making its way over your system, and will not be able to stop the condensation forming on the coils from turning to ice.
Dirty coils can cause freezing due to the layer of dirt on top of the coils preventing them from absorbing the water fast enough. Bi-annual checkups from your local HVAC professional can keep your A/C’s coils clean.
As the internal air cools, it becomes denser and does not travel as quickly. The blower fan helps move cold air by transporting hot air out of your home, which the denser cold air moves to replace. Sometimes your blower fan can break, or become damaged during normal operation. When your blower fan is not functioning correctly, that will lead to a significant change in the airflow inside of your air handler. Too much condensation will build up on the coils, and the water droplets will not evaporate or drain properly. Without the hot air moving over the proper parts, a broken blower fan can also cause a refrigerant line to freeze too.
