2. Low Refrigerant Levels
When the refrigerant level in your AC unit is low, it can cause the coils to freeze. The refrigerant helps to cool the air, so when it’s low, the unit has to work harder to keep the house cool, which can cause the coils to freeze.
If you think your AC unit is low on refrigerant, you should call a professional to check it. They can add more refrigerants and get your AC unit to work correctly.
3. Clogged Condenser Coils
If you wonder why your HVAC system is icing up, one possible reason is that the condenser coils are clogged. The primary function of coils is to release heat outside, and when they’re unable to do that effectively, it can cause your AC unit to freeze up.
To prevent this, keep the area around your condenser unit clear of debris like leaves and dirt.
If you think your condenser coils might cause your AC unit to freeze up, contact a professional HVAC technician for help. They can clean the coils and get your system back up and running.
4. Defective Thermostat
The thermostat is vital for turning the AC unit on and off. If it is defective, it may cause the AC unit to freeze up.
If you think your thermostat may be the problem, you can try replacing the batteries or adjusting the settings. If that doesn’t work, you’ll need to call a professional to have it replaced.
