Ask any HVAC technician in Sammamish and you will hear the same thing: equipment almost never 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 failing 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.
Warning Signs for HVAC Repair
Spotting the early warning signs lets you act before the problem gets expensive. Here are the most common indicators that it's time to call a professional:
- Grinding, squealing, buzzing, or banging you have not heard before
- Utility bills climbing while comfort keeps falling
- Weak airflow from the supply registers throughout the house
- A circuit breaker that keeps tripping when the system starts
- Short cycling, where the system starts and stops without ever reaching the setpoint
- An outside unit that buzzes but will not start
- Puddles near the furnace or air handler from a blocked drain line
- Air at the registers that is the wrong temperature for the mode you selected
