It’s not fun to see ice accumulating on the outside of your HVAC unit. But this is a common problem that you can safely attempt to repair on your own, depending on what’s causing it.
To understand why your HVAC unit is freezing up, read on!
4 Reasons Why Your HVAC is Freezing Up
- Poor airflow
A dirty air filter can restrict airflow to the coil, causing the temperature of the cold air to keep dropping until it freezes.
To avoid this problem, change air filters at least once a month, and check if there’s dirt or debris around the unit that may block airflow.
Aside from dirty air filters, it’s worth checking if the evaporator fan is spinning too slowly or not spinning at all. The fan motor may need to be serviced.
Clogged or leaky ductwork also results in poor airflow, so it has to be cleaned and sealed.
- Dirty evaporator coils
The evaporator coils inside your unit will get caked in layers of dirt and grime over time. You can clean the evaporator coils on your own, as long as you’re careful enough not to bend any of the coils or fins.
- Faulty thermostat
A thermostat displays the current indoor temperature, sending signals to your system to turn on and off accordingly.
A faulty thermostat may cause the unit to run too long or too cold. An overworked unit may develop frozen coils if left unchecked.
Recalibrating it or installing a new thermostat should fix the issue.
- Low refrigerant levels
If the refrigerant is low, the coil gets too cold. This lowers the pressure inside the coil, allowing moisture to accumulate and ice to form. If you see a buildup of ice on the evaporator coils, it’s a sign you may be low on refrigerant.
For your own safety, this issue is best handled by a qualified, licensed HVAC technician. They’ll have to confirm the refrigerant level and add more refrigerant if needed. Having the entire unit checked for leaks is also crucial to prevent refrigerant loss in the future.
