Furnace Tune-Ups in Asheville, NC

Combustion analysis anchors the visit, and the full checklist surrounds it:

• We perform a full combustion analysis of the system, measuring how completely and safely the furnace burns its fuel.
• We clean the burners and inspect the heat exchanger for cracks.
• The pilot assembly or ignition system gets cleaned and adjusted.
• Burner adjustment for maximum efficiency comes with a check that combustion air levels are correct.
• We test the gas valve and check for gas leaks.
• We inspect the flue pipe and draft diverter so exhaust leaves the home as designed.
• Safety and operating controls are tested and adjusted.
• We lubricate motors, bearings, and fans, check the blower motor and belt, and meter voltage and amperage.
• We check temperature rise and backup heating elements, and we evaluate your air filters.

Combustion analysis measures the gases a furnace produces while burning, which reveals how efficiently and how safely it is operating. A furnace can sound normal and still burn incompletely, wasting fuel and producing carbon monoxide it was never meant to make. The analyzer turns that invisible condition into numbers a technician can act on.

Paired with the heat exchanger inspection, the analysis covers heating safety from both directions: it confirms the combustion itself is clean, and it confirms the barrier containing that combustion is intact. The efficiency adjustments that follow mean the fuel you buy becomes heat in your rooms rather than waste up the flue.

Our technicians are background checked, licensed, insured, and continuously trained, and the combustion analysis is part of every heating tune-up we perform. One call to Bullman covers whatever your heating system needs, from this maintenance visit through furnace repair and replacement if the analysis uncovers a deeper problem.

We are available whenever you need us. Scheduling works online, through the 24/7 chat on our website, or by phone, and members of our maintenance plan receive priority on the calendar.

Your technician reviews last season’s performance with you, then services the furnace and runs it through complete cycles with the combustion analyzer in place. Homes with a heat pump get the heating side checked too, including the backup heating elements. The closing summary covers the measurements, the safety findings, and any recommendations in plain language.

The Bullman maintenance plan includes this heating tune-up and a spring cooling visit, with priority scheduling, parts discounts, automatic reminders, and a membership that transfers if you sell the home. In a full four-season mountain climate, the pair of visits covers the whole year.
