One symptom, many possible causes. That is the central challenge of HVAC repair, and it matters even more in Seattle, WA, where failures seem to wait for the most extreme weather of the year. Equipment that will not start at all might have a failed low-voltage transformer, a thermostat that has stopped calling, a control board that has lost its sequence, or a float switch shut off by a backed-up condensate drain. Equipment that runs but never catches up is a different list: a weak capacitor, a worn contactor, a low charge, a dirty flame sensor, or a clogged filter choking off the blower.
Our two most requested repairs are AC Repair and Furnace Repair. If something has stopped working, start there.
When to Call for HVAC Repair in Seattle
Catching these issues early helps you avoid costly problems. Here are the most common indicators that it's time to call a professional:
- Vents blowing warm when you want cool, or cool when you want heat
- Water around the indoor unit from a clogged condensate drain
- Weak airflow from the supply registers throughout the house
- Higher energy bills with no improvement in comfort
- New noises such as grinding, squealing, buzzing, or banging
- The outdoor unit humming but refusing to actually start
- A circuit breaker that keeps tripping when the system starts
- The system short-cycling on and off without reaching the set temperature
