If your home has central air conditioning, one potential problem it can have is frozen coils. This is often due to a problem with the refrigerant line, which causes temperatures to fall below freezing. While you may think that frozen coils will only make the air cooler, it actually has an opposite effect where the air gets warmer. The coils are unable to remove the heat from the air in your home, and then release that heat outside. If you find yourself with frozen coils, here is what you are able to do about it.
Turn Off The Air Conditioner
Shutting down your air conditioner should be the first thing you do when you have frozen coils. Try giving the entire system a rest so that the ice can naturally thaw out on its own. This can take a few hours, and it is best to not disturb the ice in fear of causing damage to the coils. As tempting as it may be to chip away at the ice, there is a huge risk of making the problem worse if you puncture the refrigerant line.
There will be water dripping from the coils in the blower unit, so get out a mop and be ready to clean up some water that is dripping out of the unit.
Check Air Flow
Ice can build up on the coils due to an airflow problem within your HVAC system. You can inspect the unit for potential problems and try to fix it. Start by looking at the air filter, since a filthy filter could be trapping all the cold air around the coil, which causes it to freeze. Swapping out the air filter after the coils thaw could fix this problem.
The coils could also be covered with debris from years of use. Consider cleaning the coils on your own, or reach out out to an HVAC professional to handle the cleaning for you.
Check For Refrigerant Leaks
Sometimes the problem with frozen coils is due to a lack of refrigerant in the system, which can be caused by a leak in the refrigerant line. An HVAC professional can put a special dye in to the line to help locate the source of the refrigerant leak, and repair the line for you. The system will then need new refrigerant put into it so that it is at the proper level of pressure to operate, which can all be done in one visit.
