Heating and cooling systems rarely fail politely, and in Redmond, WA, 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.
Warning Signs for HVAC Repair
Spotting the early warning signs lets you act before the problem gets expensive. Keep an eye out for the following clues:
- A humming outdoor unit that never kicks on
- New noises such as grinding, squealing, buzzing, or banging
- Warm air from the vents in cooling mode, or cool air in heating mode
- Water around the indoor unit from a clogged condensate drain
- A breaker that trips whenever the system tries to run
- Frequent on-off cycling while the house never gets to the thermostat setting
- Utility bills climbing while comfort keeps falling
- Weak airflow from the supply registers throughout the house
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 (425) 969-4221 for a fast inspection.
