Why is my air conditioning freezing up at night in San Antonio?

Solved: Why Is My AC Freezing Up At Night in San Antonio
In the heart of San Antonio, where the summer heat can be relentless, a functioning air conditioning system is a necessity. However, you may find yourself waking up in the middle of the night, drenched in sweat, only to discover that your AC unit is frozen solid. This is a fairly common problem that can have several different causes. Let’s explore why your AC might be freezing up at night and how you can prevent it.

Common Causes of AC Freezing
Low Refrigerant: The evaporator coil in your AC unit contains a small amount of liquid refrigerant that evaporates to cool the air. If your AC is low on refrigerant, it can cause the coil to freeze up, leading to inefficient cooling and higher energy bills.

Dirty Condenser Coil: The condenser coil in your AC unit helps remove heat from the air. If this coil becomes dirty or clogged with debris, it can’t do its job properly, causing your AC to work harder and potentially freeze up.

Faulty Blower Motor: The blower fan in your AC system circulates warm air into the ducts and redistributes cool air throughout your home. If the blower fan or its motor fails, the heat transfer process halts, causing the evaporator coils to freeze.

Thermostat Issues: If your thermostat is set too low or is located in a drafty spot, it can cause your AC to work harder than necessary and potentially freeze up.

Improper Installation: If your AC unit isn’t installed correctly, it can lead to several problems, including freezing. This includes issues like failing to insulate the evaporator coils or not leveling the AC unit properly.

Worn Out Parts: Over time, parts in your AC unit can wear out and break down, causing your AC to freeze up. This includes crucial parts like the compressor, fan motors, and evaporator coils, as well as filters and gaskets.

Damaged Ductwork: Damaged or leaky ductwork can cause your AC to work harder than necessary, leading to freezing. It can also cause cool air to escape, making it difficult for your AC to maintain a comfortable temperature.

The Solution
If your AC unit has been freezing up, don’t panic. Start by checking the thermostat and making sure it’s set to the correct temperature. Try cleaning the condenser coils and replacing any worn-out parts. If your AC unit continues to freeze up, it’s time to call in the professionals.
