One symptom, many possible causes. That is the central challenge of HVAC repair, and it matters even more in Portsmouth, NH, 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 clogged filter choking off the blower.
Most of our service calls are for AC Repair and Furnace Repair. Start there if your system isn't running right.
When to Call for HVAC Repair in Portsmouth
Recognizing the warning signs early can save you time and money. Keep an eye out for the following clues:
- Water around the indoor unit from a clogged condensate drain
- The outdoor unit humming but refusing to actually start
- Higher energy bills with no improvement in comfort
- Repeated breaker trips every time the heating or cooling kicks on
- Short cycling, where the system starts and stops without ever reaching the setpoint
- Barely any air coming out of the vents
- Unfamiliar sounds from the equipment, like squealing, grinding, or banging
- Air at the registers that is the wrong temperature for the mode you selected
Early Action Saves Money
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. Call (857) 767-3372 at the first sign of trouble.
