How do I unfreeze my AC compressor?
Thaw Out Your AC To thaw the ice out, first, you need to turn the AC’s thermostat off and turn the fan on. Leave the fan on for a few hours to allow the unit to fully defrost. In some cases, it may thaw out after an hour. In other, more extreme cases, you may need to leave the fan on for a full 24 hours.

What to Do When Your AC Unit Freezes Up in the Summer in Two Steps!
- Step One: Thaw it Out. Turn off your AC unit at the electrical breaker and let the ice thaw. Be advised, it could take a whole day for the ice to completely thaw.
- Step Two: Dry the Coils. Once the ice is gone, dry the evaporator coils.
What causes your air conditioner to freeze up?
There are many reasons why your AC unit may be freezing up. A freeze up can also be caused by low refrigerant and improper fan operation. Low refrigerant levels make the coils too cold, and a faulty fan prevents air from moving. Faulty thermostats and drainage problems are often causes of a freeze up.
Why is my AC unit freezing up inside?
When your AC system is low on refrigerant, pressure drops causing the evaporator coil to get abnormally cold. So when returning air hits the coil, humidity/moisture from the air beads ups on the coil and quickly freezes.

What do you do when air conditioner freezes up?
The first thing you need to do is turn off the air conditioner and let it defrost. After it’s had sufficient time to thaw (1-3 hours), turn on just the fan for about an hour. Use this time to change your air filter.
Why does my AC have a frozen coil?
While a frozen ac may be caused by malfunctions or damaged equipment, proper maintenance can help avoid some issues. Keep the evaporator coils clean, as dirty coils can restrict air flow across them. Replace your system’s air filters regularly.
Why is the outside of my air conditioner covered in ice?
Your outside air conditioning refrigerant line is covered in ice—which seems crazy in Arizona heat. So what’s the deal? Chances are, your indoor unit’s evaporator coil is frozen solid and cold liquid refrigerant is flowing to the outside unit through the refrigerant line (which is why it’s covered in ice).
Why does my air conditioner freeze when low on refrigerant?
When your AC system is low on refrigerant, pressure drops causing the evaporator coil to get abnormally cold. So when returning air hits the coil, humidity/moisture from the air beads ups on the coil and quickly freezes. This continues until the evaporator coil is frozen. If you’re low on refrigerant you also have a refrigerant leak.
What happens when the evaporator on an AC unit gets too cold?
The evaporator coil holds refrigerant, which is a liquid or gas that absorbs heat from warm air. (That’s right; AC units don’t really “add cold” to air; they actually “remove heat”!) If the refrigerant gets too cold, the moisture in the surrounding air freezes.
