One symptom, many possible causes. That is the central challenge of HVAC repair, and it matters even more in Haverhill, MA, 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.
The repairs homeowners call us about most are AC Repair and Furnace Repair. If something has stopped working, start there.
Warning Signs for HVAC Repair
The sooner you notice these red flags, the easier and cheaper the fix. Watch for these telltale signs:
- Utility bills climbing while comfort keeps falling
- Repeated breaker trips every time the heating or cooling kicks on
- Warm air from the vents in cooling mode, or cool air in heating mode
- The outdoor unit humming but refusing to actually start
- Frequent on-off cycling while the house never gets to the thermostat setting
- Unfamiliar sounds from the equipment, like squealing, grinding, or banging
- Puddles near the furnace or air handler from a blocked drain line
- Airflow at the registers that feels weak in every room
