Full-System Diagnosis
We find the actual fault, not just the symptom, and show you what we found.
Parts on the Truck
Igniters, motors, thermocouples, and common boards ride with us. Most repairs finish same-visit.
Boiler Expertise
Radiator and in-floor systems are half this region's housing stock. We speak fluent boiler.
Safety Check Included
Heat exchanger, CO, and venting checks on every call, because your family breathes this air.
Clean Work, Every Time
Boot covers on, mess gone. The only sign we were there is a warm house.
Honest Replace Advice
If replacement beats repair, you see both numbers with financing options. Your call, not our pitch.
Six ways a furnace asks for help
Short cycling
Kicks on and off every few minutes instead of running steady heat cycles.
Yellow burner flame
A healthy gas flame burns blue. Yellow or flickering means combustion trouble.
Cold rooms, hot rooms
Uneven heat usually points at airflow, not the thermostat.
A bill that keeps climbing
Same thermostat setting, bigger bill: the system is working too hard.
Banging, screeching, rumbling
New noises are parts wearing out. They do not fix themselves.
CO detector chirps
Shut it down and call right away. Carbon monoxide is the one we drop everything for.

Neighbors who made the same call
"Had a cold climate heat pump installed with gas furnace backup. I received 3 bids and Advantage Air had the best price without artificially lowering it with rebates. They were on time, removed the old oil furnace, coordinated all the electrical work, and did a great job explaining the new technology."
No-heat calls, answered from two shops
Asked from a lot of cold kitchens
We answer 24/7 and dispatch from both Superior and Duluth, so we are not fighting the bridge to reach you. No-heat calls in a Northland winter jump the line.
Our honest rule: if the repair costs more than a third of a new system and the furnace is past 12 to 15 years, we show you both numbers and let you decide. No scare tactics either way.
Yes. A big share of older Twin Ports homes heat with hot water, and our techs repair and replace boilers every week. Radiators, in-floor heat, combi units, all of it.
You approve an upfront price before any work starts. If a replacement makes more sense, GreenSky and Optimus financing can spread the cost into monthly payments.
