An air conditioning system may run into a lot of problems that keep it from cooling down, but there’s one thing you may not expect to reduce cooling power: ice. After all, air conditioners use refrigeration to cool down the home, so wouldn’t ice be of benefit? But your air conditioning should never freeze up, as this inhibits its ability to absorb heat. Let’s go over the heating process a bit to see why ice is a problem, and look at how to solve it.
How Ice Builds Up
Refrigerant is the medium that allows for heat exchange. As it changes into a gas at the inside coil, refrigerant absorbs the heat from the air that blows past it. Heat releases at the outside coil as refrigerant changes back to a liquid. The heat absorption indoors cools down the coil, which may also form drops of water from water vapor in the air.
If there is not enough warm air blowing past the coil, it may freeze. This could be due to a dirty air filter (so change yours every 1-3 months!) or it could be because of a problem with the fan motor. It may also be low level of refrigerant keeping the coil from allowing refrigerant to absorb heat. The major problem with ice is that it prevents the coil from absorbing additional heat, reducing the overall effectiveness of the system.
How to Clean It
Many homeowners attempt to clean the ice off themselves, but you should never do this on your own. Scraping off frost yourself is often advised against as it can damage the coil extensively, and it still will not solve the source of the problem. Thawed ice can even affect the system itself, so consult with a technician before taking any steps. A technician will find the underlying cause of the issue, so the problem won’t just happen all over again.
