Although it may seem strange for an air conditioner to develop ice in the middle of summer, freezing is actually a common HVAC issue. Ice forms when the evaporator coil becomes too cold, allowing moisture in the air to freeze instead of draining away.Restricted Airflow
Poor airflow is one of the leading causes of a frozen AC system. Common reasons include:- Dirty air filters
- Blocked supply or return vents
- Closed registers
- Dust-covered evaporator coils
- Failing blower motors
Low Refrigerant Levels
A refrigerant leak reduces system pressure, causing the evaporator coil temperature to drop below freezing. Besides ice accumulation, you may notice:- Longer cooling cycles
- Hissing sounds
- Higher electric bills
- Reduced cooling performance

Warm Air From Vents
