Boiler replacement cost in Minneapolis
Quick answer
Published Twin Cities estimates vary widely: Angi lists Minneapolis boiler replacement at about $3,200–$13,200, while local contractors publish roughly $5,500–$9,100 for a like-for-like gas boiler and $9,100–$15,600 for a condensing (95%+) upgrade. These are published references, not a guaranteed price; boiler type, venting and piping change your total.
A condensing boiler usually needs new PVC venting and a condensate drain, which is much of its price premium. CenterPoint Energy lists a $300 Minnesota rebate for a qualifying replacement boiler of 85% AFUE or higher installed during 2026. The federal 25C tax credit ended for improvements after December 31, 2025. This is educational information, not HVAC, tax or financial advice.

What most people miss
Ask for a heat-loss calculation, not the old boiler's size
Many older Minneapolis homes have oversized boilers from decades ago, and insulation or window upgrades since may have lowered the heat load. A room-by-room heat-loss calculation can justify a smaller, cheaper boiler that runs more efficiently.
How this price is built
Boiler equipment
Brand, model, input BTU, AFUE, and whether it's a standard, condensing or combi (heat plus domestic hot water) unit.
Venting and chimney
Condensing boilers vent through PVC and need a condensate drain. A standard boiler may reuse the chimney, which may need a liner. Ask what happens to a water heater sharing the chimney.
Near-boiler piping
Pumps, zone valves, expansion tank, air separator and primary/secondary piping. Steam and hot-water systems are priced differently.
Permit and inspection
A mechanical/gas permit from the City of Minneapolis. Angi lists a Minneapolis boiler replacement permit at about $132; confirm current fees.
Rebate paperwork
Who submits the CenterPoint rebate and whether the model is listed on the AHRI or ENERGY STAR directory as the rebate terms require.
What makes a quote high
Oversized replacement
Matching the old boiler's size without a calculation can cost more upfront and in fuel.
Rebates counted twice or misquoted
Ask for the program name and amount. Don't assume an electric utility rebate applies to a gas boiler.
Bundled system flush and extras
Flushing, new radiators or indirect water heaters can be legitimate but should be priced separately.
Emergency mid-winter pricing
If the boiler still runs safely, get two or three written quotes before it fails.
Itemised versus vague
A quote you can evaluate looks different from one you can't. This is what to look for, line by line.
| Item | A quote you can judge | A quote you can't |
|---|---|---|
| Equipment | Model, BTU, AFUE, type | High-efficiency boiler |
| Sizing | Heat-loss calculation shared | Same size as old |
| Venting | Venting, liner and condensate listed | Install included |
| Permit | City permit pulled and inspected | Not needed |
| Rebate | Program, amount and who files | Rebates available |
Questions to ask before you approve
- What model, BTU and AFUE are you quoting?
- How did you size it?
- What venting, chimney liner and condensate work is included?
- Which near-boiler parts are being replaced?
- Who files the CenterPoint rebate, and does this model qualify?
Message to a Twin Cities boiler installer
Copy these lines as they are. Politeness plus specifics gets answers.
- 1.“Please quote the exact boiler model, BTU and AFUE.”
- 2.“Share how you sized it.”
- 3.“List venting, chimney liner, condensate and near-boiler piping work.”
- 4.“Include the permit and say who files the CenterPoint rebate.”
When a high price is legitimate
A higher-than-expected price isn't automatically a bad one. These are the situations where it's usually justified.
- Condensing boilers need new venting and a condensate drain.
- Steam systems and old cast-iron radiators can need extra piping work.
- Combi boilers include domestic hot water and cost more than heat-only units.
- Basement access and asbestos-wrapped old pipe can add labour or abatement.

Common questions
How much does a new boiler cost in Minneapolis?
Published Twin Cities ranges run from about $3,200–$13,200 (Angi) to $5,500–$9,100 for like-for-like gas boilers and $9,100–$15,600 for condensing upgrades from local contractors. Compare the same equipment across quotes.
Are there boiler rebates in Minnesota in 2026?
CenterPoint Energy lists a $300 rebate for a qualifying residential replacement boiler of 85% AFUE or higher installed between January 1 and December 31, 2026. Check current terms before relying on it.
Is the federal tax credit still available for boilers?
No. IRS guidance says the Energy Efficient Home Improvement Credit (25C) applies to improvements placed in service through December 31, 2025.
Should I switch from a boiler to a furnace?
Converting means adding ductwork, which usually costs far more than replacing the boiler. Ask for both quotes if you're considering it.
