Common furnace issues we fix

If you're seeing any of these in winter, call.

Most Atlanta-area furnace failures fall into one of six patterns. Here's what to look for and what we typically find.

Furnace running, no heat

Usually a failed igniter, flame sensor, or gas valve. We diagnose with a combustion analyzer before recommending a fix vs. replace.

Won't ignite or short-cycles

Most often a dirty flame sensor, control board issue, or pressure switch. Common, fast to fix when caught early.

Loud bang on startup

Delayed ignition — gas builds up, then ignites all at once. Burner cleaning + heat-exchanger inspection needed before damage spreads.

Cold air from vents

Could be thermostat, blower motor, or zoning. Diagnostic in person — sounds and behavior tell us a lot before we open anything.

Yellow burner flame

Flame should be blue. Yellow means incomplete combustion → CO risk. Stop running, open a window, call us. Don't sleep with it on.

Burning smell on first run

Common for first run of the season as dust burns off. If smell persists past 30 minutes or smoke appears, turn off and call.
