Furnace Maintenance & Tune-Ups in Salt Lake City, UT

Utah's heating season runs from mid-October through April — roughly six months of daily furnace use. That's 3,000+ hours of runtime per winter, and every one of those hours accumulates wear on burners, blower motors, ignition systems, and heat exchangers. An annual maintenance visit catches the parts that are starting to fail before they strand you without heat on a 5°F January night. In our experience, 80% of mid-winter furnace breakdowns could have been prevented by a fall tune-up.

Altitude is a factor most homeowners don't think about, but it changes how we tune a furnace. Gas pressure settings that work perfectly in Denver or Boise may not be optimal at Salt Lake City's 4,300 feet. During every maintenance visit, we check manifold gas pressure with a manometer and adjust if needed, verify flame characteristics, and measure combustion efficiency with a flue gas analyzer. These aren't steps you'll find on a generic maintenance checklist — they're specific to operating a gas furnace at elevation.

Beyond preventing breakdowns, maintenance keeps your energy bills in check. A dirty blower wheel, a clogged secondary heat exchanger, or a malfunctioning gas valve can quietly reduce your furnace's effective efficiency by 10–15%. Over a full Utah winter, that translates to $200–$400 in wasted gas. Our 30-point tune-up returns your system to factory-spec performance and documents its condition so you can plan ahead instead of reacting to emergencies.

Our technicians follow a structured 30-point inspection and service protocol. We clean the burner assembly, check ignition and flame sensor operation, inspect the heat exchanger for cracks or corrosion, test the blower motor and capacitor, verify thermostat calibration, inspect the flue and venting system, test safety controls, measure temperature rise across the heat exchanger, and check the condensate drain on high-efficiency units. Every finding is documented with photos and shared with you before we leave.

We also assess your air filter, check for duct leaks at the furnace connections, and inspect the gas piping and shutoff valve. If we find something that needs repair, we give you an upfront price and let you decide — no pressure upsells. Most tune-ups take 60–90 minutes and require no follow-up visit.
