If your air conditioner is freezing up, it’s a sign that something isn’t working as it should. Ice buildup on your AC unit can lead to reduced cooling performance, higher energy bills, and even long-term damage if left unaddressed. Understanding the causes of this issue can help you take the right steps to fix it and prevent it from happening again. Here are six common reasons why your air conditioner might be freezing up.

1. Restricted Airflow – Dirty air filters, blocked vents, or a failing blower motor can reduce airflow, causing the coils to freeze.

2. Low Refrigerant Levels – A refrigerant leak can lower pressure and temperature in the system, leading to ice buildup.

3. Dirty Evaporator Coils – Dust and debris on the coils prevent proper heat absorption, making them too cold and causing freezing.

4. Thermostat Issues – A malfunctioning thermostat may cause the AC to run continuously, overcooling the system.

5. Drainage Problems – A clogged condensate drain can lead to excess moisture buildup, which can freeze on the coils.

6. Outdoor Temperature Too Low – Running your AC when it’s too cool outside can cause the refrigerant to drop below freezing, leading to ice formation.

Regular maintenance and timely repairs can help prevent these issues and keep your AC running efficiently.  Choose Newair Heating & Cooling for reliable air conditioner repair and maintenance in Mentor.
