Before you sign
- Ask for the load calculation. The size should come from a room-by-room calculation (called a Manual J), not the size of the old unit.
- Ask what's included. Equipment, labor, permit, removal of the old unit and the startup readings, each named. Six questions worth asking.
- Read the model numbers. They say what you are actually being sold. How to read them.

How much does boiler replacement cost?
As of October 18, 2026, the middle quote for a boiler replacement in our dataset was $10,100, across 9 real quotes homeowners received in 7 states. Half of them fell between $8,350 and $13,600, and the full range ran from $7,650 to $29,750.
Why do quotes for the same kind of system vary so much?
These are quotes, what a contractor proposed, not final invoices, and scope varies: some include a thermostat, a permit or removal of the old equipment and some do not. In this group the highest quote was 3.9 times the lowest.
Where do these numbers come from?
From 9 real quotes homeowners received, dated February 2026 to August 2026, either shared through our Quote X-Ray or published openly by the homeowner. Cost-model estimates never count, and a group is only shown once it holds 5 quotes.
How to read these numbers
- These are quotes, what a contractor proposed, not final invoices.
- The middle price is the median: half the quotes were lower and half higher. It moves less than an average when one quote is unusually high.
- 9 quotes is a real sample, not a survey. Prices differ by region; the state pages show the states with enough quotes.
- The quotes are dated from February 2026 to August 2026.
