One symptom, many possible causes. That is the core challenge of HVAC repair, and it matters even more in Raleigh, NC, 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 never catches up 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.
Our two most requested repairs are AC Repair and Furnace Repair. Start there if your system isn't running right.
Warning Signs for HVAC Repair
Catching these issues early helps you avoid costly problems. Here are the most common indicators that it's time to call a professional:
- Water around the indoor unit from a clogged condensate drain
- Grinding, squealing, buzzing, or banging you have not heard before
- A humming outdoor unit that never kicks on
- Rising utility costs even though the house feels worse
- Warm air from the vents in cooling mode, or cool air in heating mode
- Repeated breaker trips every time the heating or cooling kicks on
- Frequent on-off cycling while the house never gets to the thermostat setting
- Airflow at the registers that feels weak in every room
