If your air conditioning unit is freezing up, you’re not alone. A frozen evaporator coil is a common problem for homeowners in Southwest Florida, especially during the hottest months of the year. At Gilman Cooling and Heating, we help customers fix frozen AC units quickly and efficiently. Here’s what causes your AC to freeze up—and what you can do about it.
1. Low Refrigerant Levels
One of the most common reasons an air conditioner freezes is low refrigerant. When refrigerant levels drop, the pressure inside your AC system decreases, causing the evaporator coil to become too cold and form ice. This usually happens due to a refrigerant leak or improper installation.
Solution:
If you suspect a refrigerant issue, it’s best to contact a licensed HVAC technician. Gilman Cooling and Heating offers expert AC diagnostics and can repair refrigerant leaks or recharge your system safely.
2. Restricted Airflow
Poor airflow is another major cause of AC freezing. If air can’t move freely through your system, the evaporator coil can drop below freezing and accumulate frost. Common airflow problems include:
- Dirty air filters
- Clogged evaporator coils
- Blocked air vents
- Faulty blower fans
Solution:
Start by replacing your air filter and checking for any visible blockages. If your system is still freezing, our team at Gilman Cooling and Heating can perform a thorough inspection and airflow optimization.
3. Malfunctioning AC Components
Sometimes, broken parts inside your AC unit can trigger freezing issues. Faulty components such as compressors, expansion valves, or blower motors can disrupt normal operation and lead to ice buildup.
Solution:
If cleaning and basic maintenance haven’t resolved the issue, it’s time for professional help. Our certified HVAC technicians at Gilman Cooling and Heating can diagnose the problem, replace any defective parts, and get your system running smoothly again.
