Why is my air conditioner freezing up?

Finding chunks of ice on your air conditioner in the middle of summer can be an unpleasant surprise. An air conditioner can internally freeze no matter the outside temperature. Unfortunately, sometimes the ice is not visible and when the ice builds up over time, the unit can sustain serious damage.

A regular maintenance routine performed by a certified technician is crucial to ensure your AC unit is in peak shape. Technicians affiliated with HVAC 911 are licensed professionals invested in making sure your air conditioner is in reliable working conditions. They can perform both emergency services to fix your frozen AC unit and regular maintenance to prevent a variety of problems. 

Issues with the evaporating coils 

One potential cause of an air conditioner freezing is a problem with the evaporator coils, which are full of extremely cold refrigerants. When warm air blows across the coils, it activates the Freon inside of them, which ultimately creates the cool air that blows out of your air conditioner.

If something prohibits the warm air from blowing over the coils, this will result in an excessive cooling of the unit’s coils caused and cause ice to form.

How to solve the problem 

Without proper knowledge, trying to repair your own AC unit can cause more costly problems. Call HVAC 911 and be referred to a licensed HVAC contractor who can work on such emergencies and help get your air conditioner unfrozen and running.

You can also call HVAC 911 and be referred to a licensed HVAC contractor to schedule a yearly inspection on your system. This will significantly reduce potential problems before they become more severe and costly.
