Heating and cooling systems rarely fail politely, and in Concord, CA, a breakdown tends to land on the hottest afternoon or the coldest night of the year. The tricky part is how many different failures produce the same symptom. A system that runs but never reaches temperature might be fighting a weak run capacitor, a pitted contactor, a low refrigerant charge, a dirty flame sensor, or nothing more exotic than a filter so clogged the blower is starving for air. A system that will not start at all could be a tripped float switch on a backed-up condensate drain, a failed transformer, a bad thermostat, or a control board that has stopped sequencing the equipment.
Most of our service calls are for AC Repair and Furnace Repair. If something has stopped working, start there.
Warning Signs for HVAC Repair
Recognizing the warning signs early can save you time and money. Keep an eye out for the following clues:
- A humming outdoor unit that never kicks on
- Utility bills climbing while comfort keeps falling
- Grinding, squealing, buzzing, or banging you have not heard before
- Frequent on-off cycling while the house never gets to the thermostat setting
- Water pooling around the indoor equipment, often from a clogged condensate drain
- A circuit breaker that keeps tripping when the system starts
- Air at the registers that is the wrong temperature for the mode you selected
- Weak airflow from the supply registers throughout the house
Act Before It Gets Worse
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. If you notice any of these signs, call (925) 205-6501 for a prompt inspection.
