One symptom, many possible causes. That is the central challenge of HVAC repair, and it matters even more in Charleston, 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 never catches up 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. That's the place to start if you need a fix today.
Warning Signs for HVAC Repair
Catching these issues early helps you avoid costly problems. Keep an eye out for the following clues:
- Puddles near the furnace or air handler from a blocked drain line
- Repeated breaker trips every time the heating or cooling kicks on
- Vents blowing warm when you want cool, or cool when you want heat
- Weak airflow from the supply registers throughout the house
- Utility bills climbing while comfort keeps falling
- Unfamiliar sounds from the equipment, like squealing, grinding, or banging
- An outside unit that buzzes but will not start
- Short cycling, where the system starts and stops without ever reaching the setpoint
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. Don't wait, call (843) 268-6960 and we'll take a look right away.
