Why Does My AC Keep Freezing?

Why Does My AC Keep Freezing

Wondering why your air conditioner suddenly turns into an icy wonderland or starts blowing warm air? We’ve got you covered with some insights.


Several potential reasons could be causing this, each with solutions that range from simple fixes you can do yourself to more complex repairs requiring professional assistance. In some cases, the damage might be irreparable, and you might have to consider getting a new AC unit.


Leaky Coolant: Your AC uses a coolant to cool down the air in your home. If there’s a leak in the coolant system, the remaining substance can condense and freeze, leading to your AC freezing up. While professionals can temporarily patch up the leak and refill the coolant, it might be a sign that you need to start thinking about a replacement.


Blocked Air Filters: When your AC can’t draw in enough air due to clogged filters, condensation can accumulate and freeze. This can leave you sweating on hot days. The good news is that this is one of the easier issues to address. Regularly changing your air filters can prevent this from happening again.


Faulty Blower Fan: A damaged or malfunctioning blower fan can disrupt the airflow within your AC unit. This prevents warm air from reaching the condenser coil, which can then freeze up. When this happens, your entire AC system might stop blowing cool air throughout your space.


Damaged Air Ducts: Air travels throughout your home through the air ducts, so if they are damaged or blocked, it can restrict airflow. Without efficient airflow, warmer air can’t pass over the AC unit coils to prevent them from freezing up.


Air ducts can become damaged simply from age and rust, or they can get blocked by dirt and debris buildup or even pests.


Faulty Condensate Drainage: For your air conditioner to work like a champ and keep you cool on the hottest summer days, the vapor inside the machine needs a way out. When it doesn’t escape, it can freeze inside the machine—which means a frozen air conditioner and an overheated homeowner. That’s why good drainage is critical.


Understanding these common reasons behind a frozen AC can help you diagnose the issue and decide whether it’s something you can handle on your own or if you need to call in the experts. And remember, regular maintenance can often prevent these problems from occurring in the first place, keeping your home comfortably cool.
