Heating and cooling systems rarely fail politely, and in Somerville, MA, 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.
Most of our service calls are for 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:
- A humming outdoor unit that never kicks on
- Short cycling, where the system starts and stops without ever reaching the setpoint
- Unfamiliar sounds from the equipment, like squealing, grinding, or banging
- Barely any air coming out of the vents
- Water pooling around the indoor equipment, often from a clogged condensate drain
- Utility bills climbing while comfort keeps falling
- A circuit breaker that keeps tripping when the system starts
- Warm air from the vents in cooling mode, or cool air in heating mode
Act Before It Gets Worse
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. Call (857) 767-3378 at the first sign of trouble.
