Heating and cooling systems rarely fail politely, and in Vacaville, 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

- New noises such as grinding, squealing, buzzing, or banging
- Utility bills climbing while comfort keeps falling
- Weak airflow from the supply registers throughout the house
- A breaker that trips whenever the system tries to run
- Water around the indoor unit from a clogged condensate drain
- Frequent on-off cycling while the house never gets to the thermostat setting
- Vents blowing warm when you want cool, or cool when you want heat
