If you’ve noticed that your air conditioner has been freezing up at night, you’re not alone. This is a common problem that many homeowners experience, especially during the summer months. Learn about the top 5 Reasons Why Your AC Is Freezing At Night and what you can do to prevent it from happening yourself or by calling the pros at SWAN.
Reason #1: Insufficient Air Flow
The first reason why your air conditioner may be freezing up at night is due to dirty air filters. When your air filters get dirty or clogged up, it restricts the airflow through your AC, this may cause the evaporator coil to freeze up. To prevent this from happening, it’s important to change your air filters regularly, ideally every 30 to 60 days.
Reason #2: Low Refrigerant Levels
One of the most common reasons why an air conditioner freezes up at night is due to low refrigerant levels. When your AC doesn’t have enough refrigerant, it can’t absorb enough heat from your home, causing the coils to freeze over. If you suspect that your air conditioner has low refrigerant levels, it’s important to contact a professional HVAC technician to inspect and recharge your system.
Reason #3: Outside Temperature
The temperature outside can play a significant role in causing your air conditioning to freeze up at night. When the outdoor temperature drops, your AC’s evaporator coil can become too cold, causing moisture to freeze on the coil and eventually block airflow.
o prevent this from happening, it’s important to have regular maintenance performed on your AC and ensure that it’s properly sized for your home and the local climate
Reason #4: Defective Blower Motor
A defective blower motor can also cause your air conditioning to freeze up at night. If your blower motor is not functioning properly, it can’t circulate air through your AC system, causing the evaporator coil to become too cold and eventually freeze up.
If you suspect that your blower motor is defective, it’s important to contact a professional HVAC technician to diagnose and repair the issue.
Reason #5: Stuck Contactor
Finally, a stuck contactor may be causing your air conditioner to freeze up at night. This happens when the contactor, which is responsible for turning your AC on and off, becomes stuck in the on position, causing your AC to run continuously and eventually freeze up. If you suspect that your contractor is stuck, it’s important to contact a professional HVAC technician to inspect and repair it.
How to Prevent Your Air Conditioner from Freezing at Night
Now that you know the top 5 Reasons Why Your AC Is Freezing At Night, here are some tips on how to prevent it from happening:
1) Change your air filters regularly to ensure that your AC is getting enough airflow.
2) Keep all of your air vents open and unobstructed to ensure that your AC is circulating air properly.
3) Have your AC’s coils cleaned regularly by a professional HVAC technician to prevent them from becoming dirty and clogged.
4) Have your thermostat inspected and replaced if it’s malfunctioning or not functioning at all.

What To Do If Your AC Freezes
Turning off your air conditioner and allowing it to thaw should be your first course of action if it freezes. Attempting to use your AC when it’s frozen can harm your system and result in expensive repairs. Check your air filters to discover whether they’re dusty or blocked after your AC has thawed. If they are, swap them out for fresh ones.
