Furnace Tune-Ups in Greenville, SC

Safety testing leads the checklist, and documentation closes it:

• We test carbon monoxide levels, the direct measurement of heating safety.
• We clean and adjust the burners and inspect the heat exchanger.
• We clean the pilot assembly and inspect the flue pipe and gas valve, checking gas pressure at the valve.
• We replace your disposable filter with a pleated filter, included in the visit.
• We test and adjust the safety and operating controls and check thermostat operation.
• We check the blower motor and belt, safety test and tighten all wiring, and lubricate motors, bearings, fans, and circulator pumps.
• We measure temperature rise and check fan speeds.
• We flush the condensate drain, visually inspect the duct system, and set marked dampers to their heating position.
• We test your smoke detectors, check humidity, and leave a report card on the equipment’s condition with any recommended repairs.

A furnace burns fuel inside your home, so the first question every heating season is whether the combustion stays where it belongs. The carbon monoxide test answers that question with a number, and the heat exchanger and flue inspections confirm the hardware behind the number. We test your smoke detectors on the same visit because working alarms are the last line of the same defense.

Once safety is established, the efficiency work pays its own way. Clean burners, correct gas pressure, verified fan speeds, and an accurate temperature rise mean the furnace converts fuel to warmth the way its ratings claim, and the pleated filter keeps the blower breathing freely through the season. Annual service also helps satisfy manufacturer warranty requirements.

Our standard is to fix it right the first time, and our tune-up is built to make that possible: trained technicians, recorded measurements, video documentation, and a written report card you keep. You get a photo of your technician and an on-the-way message before arrival, and upfront pricing presented before any recommended work begins.

Every job carries a one-year workmanship warranty, and callbacks within 30 days are free of charge. If the tune-up finds a failing part, our furnace team handles the repair, and one call covers it all: heating, cooling, plumbing, electrical, and generators under one roof. Booking is available online, by phone, and through 24/7 website chat.

The technician reviews your notes from last season, services the furnace through the full checklist, and runs complete heating cycles while testing carbon monoxide levels. We also service heat pumps, so tell us about every system when you schedule. You finish with the report card and upfront pricing on whatever the furnace needs, and you decide what to approve.

The Carolina Comfort Club is our HVAC maintenance plan, with two tune-ups a year, one for heating and one for cooling, plus priority service, reduced dispatch fees, and savings on repairs.
