One symptom, many possible causes. That is the central challenge of HVAC repair, and it matters even more in Spartanburg, SC, 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 filter clogged badly enough to starve 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
Catching these issues early helps you avoid costly problems. Keep an eye out for the following clues:
- Short cycling, where the system starts and stops without ever reaching the setpoint
- A breaker that trips whenever the system tries to run
- Puddles near the furnace or air handler from a blocked drain line
- Weak airflow from the supply registers throughout the house
- The outdoor unit humming but refusing to actually start
- Vents blowing warm when you want cool, or cool when you want heat
- Unfamiliar sounds from the equipment, like squealing, grinding, or banging
- Rising utility costs even though the house feels worse
Early Action Saves Money
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. Don't wait, call (864) 215-4948 and we'll take a look right away.
