Heating and cooling systems rarely fail politely, and in Mountain View, CA, a breakdown usually arrives 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.
The repairs homeowners call us about most are AC Repair and Furnace Repair. Start there if your system isn't running right.
When to Call for HVAC Repair in Mountain View
The sooner you notice these red flags, the easier and cheaper the fix. Here are the most common indicators that it's time to call a professional:
- Puddles near the furnace or air handler from a blocked drain line
- The outdoor unit humming but refusing to actually start
- Frequent on-off cycling while the house never gets to the thermostat setting
- Barely any air coming out of the vents
- Rising utility costs even though the house feels worse
- Grinding, squealing, buzzing, or banging you have not heard before
- A circuit breaker that keeps tripping when the system starts
- Warm air from the vents in cooling mode, or cool air in heating mode
Early Action Saves Money
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. At the first hint of a problem, call (650) 220-0820 for a fast inspection.
