Air conditioning is essential to your well-being and comfort in Ingram, TX. The last thing you want to deal with in the middle of the sizzling hot summer season is a broken air conditioner. A common issue is a frozen up AC unit. Here are three possible causes of why air conditioners freeze up and some tips on what you can do to prevent this from happening.

1. Dirty Air Filter

Air filters trap dust and debris in your home’s air. When the filters get clogged, they hinder airflow across the evaporator coil. The refrigerant in the evaporator coil isn’t able to absorb heat from your house’s air, so it keeps getting colder. Moisture from the warm air condenses and freezes onto the coil, resulting in ice buildup. Be sure to check and replace the air filter every month.

2. Debris Buildup on Evaporator Coil

Dust and debris can build up on the evaporator coil even if you do change the filter once a month. Filters only trap large particles, and layers of small particles will accumulate on the coil over time. The best way to prevent a dirty evaporator coil is to schedule an annual AC maintenance visit each spring.

3. Refrigerant Leak

A low refrigerant level causes low pressure in the air conditioning system. What’s left of the refrigerant isn’t able to move through the coils. It remains in place and keeps getting colder. Frost and ice develop on the evaporator coil and copper tubing between the indoor and outdoor unit. Only certified HVAC technicians can diagnose and repair a refrigerant leak.
