A clogged air filter restricts airflow and forces your HVAC system to work harder. Poor airflow can lead to:- Reduced cooling performance
- Frozen evaporator coils
- Higher energy bills
- Uneven indoor temperatures
Refrigerant Leaks
Low refrigerant levels are one of the most common causes of warm air. Refrigerant absorbs heat from your home, and without the proper charge, cooling efficiency drops dramatically.Signs of a refrigerant issue include:
- Warm air from vents
- Hissing sounds
- Ice buildup on refrigerant lines
- Long cooling cycles
