Heating and cooling systems rarely fail politely, and in Renton, WA, a breakdown usually arrives on the hottest afternoon or the coldest night of the year. What surprises most homeowners 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.
Our two most requested repairs are AC Repair and Furnace Repair. That's the place to start if you need a fix today.
Warning Signs for HVAC Repair
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:
- Unfamiliar sounds from the equipment, like squealing, grinding, or banging
- The outdoor unit humming but refusing to actually start
- Puddles near the furnace or air handler from a blocked drain line
- Higher energy bills with no improvement in comfort
- A circuit breaker that keeps tripping when the system starts
- Warm air from the vents in cooling mode, or cool air in heating mode
- Frequent on-off cycling while the house never gets to the thermostat setting
- Weak airflow from the supply registers throughout the house
