How Boiler Repair Works When You Call Us
Honest phone triage
Tell us the boiler age and the symptom. We will tell you over the phone if this sounds like a repair call or a replacement conversation. Not every call has to end in a truck roll.
Tech on-site for combustion and water-side diagnosis
We test combustion, draft, water chemistry, section integrity, and controls. Combustion analyzer on every call. CO builds up in enclosed basements, so we check it every time.
Repair path priced in writing
Cast-iron section replacement, circulator swap, controls upgrade, outdoor reset retrofit.
Repair, pressure test, combustion tune
We leave you with a CO reading, a water pressure reading, and a written maintenance schedule so the next winter does not surprise you.

Boiler Repair Questions We Hear from Duluth Homeowners
Common repairs. Cast-iron section replacement. Full replacement cost depends on efficiency tier.
Usually yes. Cast-iron boilers can last 50+ years if water chemistry was managed over that time. We find parts through specialty distributors. Write us off only after we have looked at it.
Yes. A replacement needs permits from City of Duluth Construction Services & Inspections, at City Hall, 411 W 1st Street. Venting into an unlined chimney must be addressed on any replacement, which often means relining. We pull the permit and handle the inspection.
Depends on the home. Older homes built around radiant heat often keep the boiler, because a forced-air retrofit has to fight the way the house was built. Mid-century ranches already on forced-air usually stay that way. We walk through the math with you.
Yes. We handle burner replacement, the chimney liner requirement, oil tank decommissioning, and combustion-air updates. Unlined clay-tile chimneys must be relined because flue gas is acidic on high-efficiency gas burners and eats the tile.
Boiler is oversized for the mild day. Outdoor reset controls fix it by letting the boiler modulate to match outdoor temperature instead of firing full-blast on every call. A retrofit can pay back in fuel savings over a few winters.

They were the second people called, we were without heat for a day and half. After a day and half waiting for the first business to fit us in we called advantage air.They were at our house within 2 hours and fixed our boiler. Great job and great service.
Chase went above and beyond to fix my boiler and water heater that were both leaking. I highly appreciated his kindness, professionalism, diligence, and patience (as he reassured me when I asked multiple times if they were going to explode hah). I will definitely be requesting him for our yearly service check appointments! Thanks, again, for your help Advantage Air and Chase!
Great service! Stopped in last Thursday and had someone in Monday to check and fix our boiler. Bryce was very helpful. Will call again if needed!
