Why is my Air Conditioner Freezing up?
There could be a number of reasons for this and here at SunDollar A/C & Heat, we would like to walk you through a few.
Insufficient Air Flow
Anything that restricts the air flow in your unit will cause the system’s evaporator coil to freeze up. There are a few reasons that air may not be flowing efficiently. The most common problem is a dirty air filter.
If you are running your AC unit continuously, we recommend replacing or cleaning the air filter once a month. Other air flow problems include blocked or closed ducts and vents, a faulty fan and/or dirt on the evaporator coils. Evaporator coils need regular cleaning, we recommend this once a season.
Low on Freon
Another thing that causes an AC freeze up is low refrigerant or Freon. This causes a drop in pressure in the evaporator coil which then allows moisture in the air to accumulate and freeze on the coil. Low refrigerant or Freon is caused by a leak. If the cause of your freeze up is a low refrigerant, you need to contact SunDollar A/C & Heat, and one of our certified technicians will assist in the repair. This includes finding and repairing the leak and refilling your refrigerant levels.
Air conditioners are designed to run in a specific temperature range. Most of them will not run well below 60°F. Often a freeze up occurs because night-time temperatures are dropping too low for the unit to function properly. When the air is too cool the pressure inside the system will drop and will cause a freeze up.
