If something prohibits the warm air from blowing over the coils, this causes the evaporator coil to allow the refrigerant to cool too much, causing it to fall below freezing and ice over. Or if the refrigerant pressure is wrong inside the coils, then your system’s coils can become too cold and can quickly freeze up.

What do you do when your condenser is frozen?
If your AC unit is frozen, take steps to unthaw the unit and let the coils dry. To do this, simply switch your thermostat to 'off' and your fan to 'on. ' This will minimize further damage and let you get a better view of what's happening to your machine.
Is it normal for AC condenser to freeze up?
As you may have guessed, your air conditioner unit freezing up on a hot day is not normal. If this happens, there's no need to panic. Often the issue can be solved with a little troubleshooting. If the AC unit is left frozen for too long however, you may find yourself with a bigger problem.
Why is my AC condenser freezing up?
Refrigerant lines can kink, fans can stop moving, filters can become clogged, and things can leak. Any of these things causes a drop in pressure, allowing the refrigerant to expand too much and become too cold. Refrigerant is also an essential part in ensuring a regulated temperature throughout your machine.
8 Reasons Why Your Ac Is Freezing Up
What causes your condenser to freeze up?
If something prohibits the warm air from blowing over the coils, this causes the evaporator coil to allow the refrigerant to cool too much, causing it to fall below freezing and ice over. Or if the refrigerant pressure is wrong inside the coils, then your system's coils can become too cold and can quickly freeze up.
Why does condenser freeze up?
If the refrigerant level is too low, then the coils will become too cold and start to ice up. Low levels of refrigerant are typically caused by a leak in the system which must be sealed. If you are running your AC system when the outside air is cooler than 62 degrees Fahrenheit, then icing can occur.
How do I keep my AC condenser from freezing?
Change Your Air Filter The leading cause of a frozen HVAC system is a dirty air filter. The air filter cleans the air circulated into your home. As your AC system runs throughout the summer, the filter catches dirt, pollen, dust, and other allergens. This can restrict airflow and could lead the HVAC coils to freeze.
What To Do When Air Conditioner Freezes Up: Air Conditioner Tips For Summer
How do I keep my condenser from freezing?
- Have the refrigerant level checked. - Change the filter monthly. - Keep the supply vents open. - Have the fan speed increased. - Have the thermostat checked out. - Inspect the condensate drain weekly. - Make sure any window units you have are angled correctly.
How do you unfreeze a condenser?
- First, turn your air conditioner off at the thermostat. - Then, change the fan setting from 'auto' to 'on. ' - The fan will slowly defrost the system. - Once your air conditioner is ice-free, you can turn it back on and reset the fan to auto (This may take an hour or more).
Why Does The Evaporator Coil Freeze (And How To Diagnose It)
What causes an AC condenser to ice up?
If your system has low refrigerant levels or is leaking refrigerant, ice can start building up on your air conditioning system. When your system has little refrigerant, it can't work effectively, and the reduced pressure could result in nearby water vapor freezing up on the surface of the coil.
How long does it take for a condenser to unfreeze?
It can take up to an 1 hour or 24 hours to unfreeze your air conditioner. It all depends on the extent of the ice buildup. As you're waiting for the unit to thaw, you should keep an eye out for: An overflowing drain pan.
