Boilers in Proctor’s Older Homes
Proctor grew up around its rail yard on Thompson Hill, and plenty of its houses date from those early decades. According to the U.S. Census Bureau’s American Community Survey 2024 5-year estimates, about 26 percent of Proctor’s homes were built before 1940 and the median year built is 1968. Houses that age are where hot water and steam boilers with cast iron radiators still do the heating.
Most Proctor homes burn natural gas, about 75 percent by the same Census figures, so most boilers we see here are gas fired. Some are newer condensing or combi boilers that make the hot water too. Each type fails in its own way, so we start by finding the actual fault in the loop, not just the cold room you noticed.
We repair circulator pumps, zone valves, expansion tanks, aquastats and controls, and we bleed and rebalance loops so every room heats. When a repair stops paying, we price a high-efficiency or combi replacement next to the repair. More on our boiler work is on our boiler repair page, and everything we do in town is on our Proctor page.

Boiler Repair Questions We Hear from Proctor Homeowners
Yes. The City of Proctor requires a permit before anyone installs, alters, repairs or replaces a gas, mechanical or plumbing system, under the Minnesota State Building Code, and its Building Safety Division does the inspections. City Hall is at (218) 624-3641. On a replacement, we pull the permit.
Often. Cast iron boilers last a long time when the water side has been looked after, and many parts are still made. We tell you straight when it is time to replace.
Usually not in an older Proctor house. Forced air means running ductwork through a house built without it. A repair, or a modern boiler in the same spot, is the usual answer. If you want cooling too, ask about a ductless heat pump.
It can work well. Condensing boilers save the most when the water they send out runs cooler, and many older radiator systems have plenty of radiator for the house. The part that needs checking is venting: a condensing boiler vents differently, so the old chimney is usually not reused as it is.
Hard. NOAA’s 1991-2020 normals for Duluth International Airport, the closest long-record station, average about 9,115 heating degree days a year, a January low around 2°F and about 38 nights below zero. A service visit before the heating season catches worn parts early.
Sometimes, through your gas utility. The programs and amounts change each year, so we check what applies when we write your estimate.

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!
