When your HVAC isn’t working as it should, it can make your home uncomfortable and drive up energy costs. Here are some common causes:
- Thermostat issues: Wrong settings, dead batteries, or miscalibration can prevent the system from signaling heat or cooling.
- Clogged air filters: Dust-choked filters restrict airflow, forcing the system to overwork or shut down.
- Obstructed vents or ducts: Closed or blocked vents, or leaky ductwork, interfere with air circulation.
- Electrical or power problems: Tripped breakers, faulty wiring, or power switch issues can stop your HVAC from functioning.
- Refrigerant or heat pump faults: Low refrigerant, failing compressors, or a broken reversing valve (in heat pumps) can prevent proper temperature control.
- Mechanical failures: Worn components like motors, blower assemblies, or control boards may malfunction.
If simple fixes like switching thermostat mode, replacing filters, or checking vents don’t help, it’s time to call a professional for diagnosis and repair.
