During the summer, when it’s hot and humid, you may rush home to enjoy the Arctic blast of your high-performing cooling system. However, it’s not so pleasant to come home to a frozen air conditioner that can no longer keep your home and its occupants comfortable. Don’t lose your cool, the HVAC pros at MightyServ can break the ice and restore your comfort.
So, why is your AC freezing up? Our team will get to the bottom of your polar predicament and make the necessary AC repairs. In the meantime, here are some of the causes behind your air conditioner turning into an ice cube.
Frozen Air Conditioner Causes and Solutions
To avoid high AC repair bills and prevent your AC freezing up, apply the preventive measures below.
1. Clogged Air Filter
A clogged air filter is typically to blame for your AC freezing up. Dust and dirt build up and prevent proper air flow. As a result, your refrigerant over cools the air and freezes the condensation that collects on your air conditioner. Oddly enough, this can also cause the AC to blow warm air.
Preventive Measure: Clean your air filter monthly. For best results, change it at least every three months. This can save you money on your energy bill and prolong the life of your unit.
2. Low Refrigerant
Low refrigerant levels can also cause your evaporator coil to freeze. Our NATE-certified technicians can check your coils for holes, cracks, and leaks.
Preventive Measure: Call MightyServ immediately if you suspect a leak. Turn off the AC until we arrive. Once there, our team will make the necessary AC repair and restore a chill environment to your home.
3. Drainage Issues
Drainage issues are another leading cause of frozen AC components. Loose drainage pipes can cause water leaks that later freeze up.
Other causes of drainage-related freezing include:
- Clogged drainpipe
- Loose drain line
- Debris inside the drain line
Preventive Measure: On particularly humid days, make sure the water is draining properly from your AC. Contact our team to clear the drainpipe and make any other required AC repairs.
4. Thermostat Levels
If you set your thermostat on low temperatures, it leaves your AC constantly running. It can also transform your cooling unit into an icicle. However, there’s an easy fix for that.
Preventive Measure: Avoid overuse of your AC. For example, do you really need to keep it on at night or can you open a window or use a fan instead. Of course, you’ll want to leave your AC running when it’s dangerously hot outside. However, with thoughtful usage, you can prevent expensive AC repair or replacement due to your AC freezing up.

5. Fan Malfunction
If your fan isn’t working properly, it can freeze your AC. Check the fan to see if it’s moving. If the blades move slowly or produce a rattling sound, something isn’t right.
Preventive Measure: An improperly installed fan can cause condensation to build up. So, watch for signs of excess moisture that can lead to frozen coils. Someone from our team can perform the necessary AC repair or replacement of the fan and other impacted components.
