One symptom, many possible causes. That is the core challenge of HVAC repair, and it matters even more in Marysville, 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 falls behind is a different list: a weak capacitor, a worn contactor, a low charge, a dirty flame sensor, or a filter clogged badly enough to starve the blower.
The repairs homeowners call us about most are AC Repair and Furnace Repair. Start there if your system isn't running right.
Warning Signs for HVAC Repair
The sooner you notice these red flags, the easier and cheaper the fix. Watch for these telltale signs:
- Puddles near the furnace or air handler from a blocked drain line
- Vents blowing warm when you want cool, or cool when you want heat
- Unfamiliar sounds from the equipment, like squealing, grinding, or banging
- Rising utility costs even though the house feels worse
- Barely any air coming out of the vents
- Repeated breaker trips every time the heating or cooling kicks on
- The system short-cycling on and off without reaching the set temperature
- A humming outdoor unit that never kicks on
Don't Wait for a Total Failure
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. Don't wait, call (425) 969-3340 and we'll take a look right away.
