HVAC Proposal Example: A Complete Sample You Can Copy
A complete HVAC proposal example for a furnace-and-AC changeout: equipment, scope, itemized pricing, rebates, allowances, warranty split, and payment terms, filled in and ready to adapt.
Published July 14, 2026
Most HVAC proposal advice tells you what sections to include. It's harder to find a finished one you can actually copy. Below is a complete example proposal for a residential furnace-and-AC changeout, the most common job most shops quote, written the way it should read when it lands in a homeowner's inbox. Every section is filled in with real-shaped numbers and specifics. If you want the reasoning behind each part instead of the finished document, that lives in how to write an HVAC proposal that wins the install.
The example is a $11,200 job: replacing a dead 80% furnace and a 13-SEER condenser with a two-stage 96% furnace and a 16-SEER2 system in a 2,100 sq ft two-storey house. Swap the numbers for your own; the structure is what does the work.
The example, section by section
Why this example wins where a one-line bid loses
A competing quote for the same job might say “replace furnace and AC: $9,800.” It's cheaper on paper and it loses more often than you'd think, because the homeowner can't tell what they're buying. The example above wins on four specifics the lump-sum bid hides: the named equipment (a two-stage 96% furnace is not the builder-grade 80% the cheap bid may be quietly quoting), the Manual J that proves the system is sized rather than guessed, the commissioning steps that separate a real install from a set-and-run, and the written change-order clausethat turns “surprise” costs into agreed ones. Those are the same details a good proposal tool forces you to include.
Adapt it to your job type
The eight sections hold for any HVAC job; what changes is the weight. A commercial or RFP install needs submittals, bonding, and phasing, worked through in the commercial HVAC proposal template. When you want to present tiered pricing, the good, better, best HVAC proposal shows how to lay out three options so the middle one sells. A straight repair or service quotecan drop to a one-page format, the same shape the job quote generator produces.

Frequently asked questions
What should an HVAC proposal include?
Eight sections: a system overview, equipment listed by brand and model number, the scope of work including commissioning steps, itemized pricing, rebates and financing, allowances and exclusions, the warranty split (manufacturer parts, compressor, and labour), and payment terms with a signature block.
How long should an HVAC proposal be?
One to three pages for a residential changeout. Long enough to name the exact equipment, count the scope, state exclusions, and split the warranties; anything longer usually buries the total.
What makes an HVAC proposal win against a cheaper bid?
Named equipment (so the client can verify what they're buying), a Manual J load calculation that proves the system is sized rather than guessed, listed commissioning steps, and a written change-order clause for surprises.
Should rebates go in the proposal?
Yes. List the qualifying manufacturer and utility rebates with amounts and say who files the paperwork. A visible rebate section routinely closes deals a bare price cannot.
