Boiler Repair and Installation
Thousands of Minneapolis and St. Paul homes built before 1950 heat with a boiler and radiators. We repair them, maintain them and replace them with people who understand hydronic heat.
- Hot water and steam systems
- Cast iron and high-efficiency condensing boilers
- $89 diagnostic, waived with repair

Boiler heat is quiet, even and comfortable, and a well-kept boiler can outlast two furnaces. It is also a different trade from forced air. Circulators, zone valves, expansion tanks, air separators, pressure relief valves and steam traps all need someone who works on them regularly.
Signs your boiler needs attention
- Some radiators hot, others cold
- Banging, gurgling or kettling noises
- Pressure gauge creeping up or relief valve dripping
- Water on the floor around the boiler
- Pilot or burner will not stay lit
- Radiators need bleeding again and again
- No heat on one zone
- Rust streaks or soot on the jacket

Replacing an old boiler
Many original boilers in the cities are far larger than the house needs, because they were sized for uninsulated walls and open windows. A right-sized modern boiler burns noticeably less gas. High-efficiency condensing boilers reach 95 percent AFUE, though they need the right radiator temperatures and venting to deliver it. We will tell you honestly whether condensing makes sense for your system or whether a quality cast iron boiler is the better buy.
Want air conditioning in a boiler house?
No ducts is not a problem. Ductless mini-splits add cooling room by room without tearing into plaster, and you keep the radiator heat you like.
What affects boiler costs
- Hot water or steam. Steam systems have more components to service
- Cast iron versus condensing, and the venting each needs
- Number of zones and the controls
- Asbestos on old piping, which must be handled by a licensed abatement firm before work
- Whether you add an indirect water heater to the boiler

Boiler Repair & Installation FAQ
How long does a boiler last?
Cast iron boilers commonly run 20 to 30 years or more. Condensing boilers typically last 15 to 20 with annual service.
How often should a boiler be serviced?
Once a year before the heating season. We clean the burners and heat exchanger, test combustion and check the pressure, expansion tank and safeties.
Why are my radiators banging?
In hot water systems it is usually trapped air or a failing circulator. In steam systems it is usually water sitting in a pipe that has lost its slope, or a bad trap or vent. Both are fixable.
Do you work on steam?
Yes, including one-pipe and two-pipe steam systems in older Minneapolis and St. Paul homes and apartment buildings.
