South Carolina winters may be milder than the northeast, but when temperatures drop into the 20s and 30s in Greenville, a broken furnace or heating system is a serious problem. First Class Heating & Air provides fast, professional heating repair throughout the Upstate with same-day service and honest, flat-rate pricing.
Our technicians are experienced with all types of heating systems, gas furnaces, electric furnaces, heat pumps, and ductless mini-splits. We diagnose the problem quickly, explain your options clearly, and get your heat back on as fast as possible.
Common heating problems we repair in Greenville homes include failed ignitors, malfunctioning blower motors, cracked heat exchangers, thermostat issues, pilot light problems, and short cycling. We carry the most common parts on our service trucks so many repairs can be completed on the first visit.
Safety is always our priority when working on heating systems. Gas furnaces can develop carbon monoxide leaks from cracked heat exchangers, a potentially life-threatening situation. Our technicians perform thorough safety checks as part of every heating repair to ensure your family's safety.
We serve Greenville, Simpsonville, Mauldin, Greer, Taylors, Spartanburg, and surrounding communities with Emergency heating repair. No overtime charges, no holiday surcharges, just flat-rate pricing you can count on.
Signs You Need Furnace & Heating Repair
No Heat or Insufficient Heat
If your furnace is running but your home isn't getting warm, you could have a failing blower motor, a clogged filter, or a heat exchanger problem.
Strange Noises from Furnace
Banging, popping, squealing, or rumbling noises indicate mechanical problems that will worsen if not addressed promptly.
Yellow or Flickering Pilot Light
A healthy pilot light is blue. If it's yellow or flickering, it may indicate a ventilation problem or carbon monoxide risk, call immediately.
Frequent Cycling On and Off
Short cycling wastes energy and puts excessive wear on your furnace. It's usually caused by a dirty filter, thermostat issue, or oversized system.
Carbon Monoxide Detector Alert
If your CO detector goes off, evacuate your home immediately and call 911 first, then call us. A cracked heat exchanger is a common cause.
