Ask any HVAC technician in San Francisco and you will hear the same thing: equipment seldom breaks down on a mild day. It waits for a heat wave or a hard freeze. What makes repair tricky is that very different faults look identical from the thermostat. If the system runs but cannot hold temperature, the cause could be a weak run capacitor, pitted contactor points, a refrigerant leak, a fouled flame sensor, or just a filter packed so tight that airflow collapses. If it will not start at all, look to a float switch tripped by a clogged condensate line, a dead transformer, a faulty thermostat, or a control board that no longer sequences the equipment.
The repairs homeowners call us about most are AC Repair and Furnace Repair. If something has stopped working, start there.
Signs You Need HVAC Repair in San Francisco
Recognizing the warning signs early can save you time and money. These are the signals our technicians see most often:
- Air at the registers that is the wrong temperature for the mode you selected
- An outside unit that buzzes but will not start
- Higher energy bills with no improvement in comfort
- Weak airflow from the supply registers throughout the house
- The system short-cycling on and off without reaching the set temperature
- Water pooling around the indoor equipment, often from a clogged condensate drain
- Unfamiliar sounds from the equipment, like squealing, grinding, or banging
- Repeated breaker trips every time the heating or cooling kicks on
