Modern homeowners rely on their air conditioners to keep their homes cool. When your AC malfunctions, you could find yourself facing extreme discomfort. One problem that you could encounter with your air conditioner is ice forming on the evaporator coil. AC coils freeze when the flow of air through your compressor is restricted. There are a few things that you can do to try and get rid of the ice and get your AC running efficiently once again.
1. Turn Off Your AC
The first thing you should do when you spot ice forming on your evaporator coils is shut down your AC system. The longer the system runs, the more ice will accumulate. It's nearly impossible to access your AC when the evaporator coil is frozen. This means that you won't be able to make any repairs until the ice has melted. By shutting your AC system down, you allow the internal temperature of the compressor to rise. The ice will melt naturally and you can access vital components to make any necessary repairs.
2. Change the Air Filter
Another simple approach to addressing frozen AC coils is changing the air filter. Your AC is equipped with a filter that removes dirt, debris, and other contaminants from the air before it is circulated through your home. These air filters can become clogged over time. A clogged air filter restricts the amount of air that can be pushed through your AC system. The result is an accumulation of cold air inside the compressor. You should change your air filter regularly to help avoid the restriction of air that can cause an evaporator coil to freeze up.
3. Look for a Refrigerant Leak
Your AC system relies on refrigerant to help create cool air. Refrigerant plays a vital role in the transfer of heat between the air pulled into the compressor and the air pushed through your home's vents. Any leaks in the refrigerant lines can compromise this transfer of heat and cause ice to start forming on the evaporator coil. You should conduct a visual inspection for refrigerant leaks if your coils are freezing up.
It's important that you don't come into physical contact with any refrigerant while conducting your search. Exposure to refrigerants could cause serious health problems. Only an experienced HVAC technician should attempt to repair any refrigerant leaks that are compromising performance and causing your AC coils to freeze.
