Common HVAC Problems We Solve
HVAC systems are complex, and a single symptom can point to a variety of underlying issues. Our experienced technicians at Res Air LLC. are trained to quickly identify the root cause of your problem. We frequently resolve these and many other common issues for Alpharetta homeowners:
- System Won’t Turn On: May be caused by thermostat issues, tripped breakers, or a problem with the unit’s power supply. We trace the electrical path to find the exact point of failure.
- No Cool or Warm Air: Low refrigerant, a failing compressor, or furnace ignition issues can be responsible.
- Poor Airflow: Often due to clogged filters, malfunctioning blower motors, or duct obstructions.
- Frequent Cycling: Short cycling could stem from an oversized unit, faulty thermostat, or restricted airflow.
- Strange Noises: Grinding, squealing, or rattling sounds often signal loose parts, worn bearings, or compressor trouble.
- Unpleasant Odors: Musty smells indicate mold growth; burning smells suggest electrical or mechanical failure.
- Water Leaks or Puddles: Pooling water usually comes from a clogged condensate drain or frozen evaporator coil.
