Boiler service calls in Minneapolis homes
A lot of Minneapolis still heats with water. Four-squares, duplexes and bungalows built before 1940 often kept their boiler when the neighbors converted to forced air, and many of those are cast-iron units that have run for decades. The calls follow the season: radiators cold at the top from trapped air, a relief valve weeping because the expansion tank lost its air charge, a circulator that hums without moving water, and steam pipes that bang after a basement remodel knocked a main out of pitch.
When a boiler needs replacing, the first question is steam or hot water. Hot-water systems can move to a modulating condensing boiler vented in PVC, which leaves the water heater alone in the old chimney and may call for a liner. Steam systems need a steam boiler. Pipe wrap in houses this old can contain asbestos and gets tested before anyone cuts.

What does boiler work cost in Minneapolis?
Repairs are a written flat-rate price before any work. A boiler tune-up falls in our $129–$349 maintenance range, confirmed when you book. Replacing a gas boiler runs about $4,000–$9,000 nationally (HomeGuide, 2026), not our price; see the boiler replacement cost guide. For what drives a quote locally, see HVAC cost in Minneapolis.

Boiler service in Minneapolis: questions
Does a new condensing boiler in Minneapolis leave the water heater needing a chimney liner?
It can. A condensing boiler vents in PVC, so the old chimney is left serving only the water heater. A chimney sized for two appliances can then be too big and too cool for one, and exhaust may condense or draft poorly, so a liner is often needed. We check the draft and the chimney's condition before quoting and list any liner as its own line.
Does old pipe wrap on a Minneapolis boiler have to be tested for asbestos before a repair?
In houses built before 1940, pipe wrap can contain asbestos, so any wrap that would be cut or disturbed gets tested before anyone touches it. If the test is positive, work on that section stops and we tell you, so a qualified abatement contractor can handle it before the repair continues.
