HVAC proposal template: how to quote your first system replacement (the price range, the scope, what the quote must include)

Published November 3, 2026 · Prices, the tax credit, warranty deadlines and the federal cancellation rule checked November 3, 2026

• Free. The proposal template comes by email as a PDF, a Word file and a Google Doc.
• Deepsel is our product: free estimate, invoice and scheduling software for contractors (scheduling, quotes, invoicing, card payments). One section, the one before the FAQ, says what it does and doesn't do for this job.
• Price ranges come from Housecall Pro's customer data, which is self-selected, and from what owners say on Reddit. Neither is a survey, and neither can be cut by state.
• Not legal or tax advice. The tax credit, contract and cancellation rules come from IRS, FTC and state pages I read on November 3, 2026.

Quote a system replacement from your own costs: the equipment at what your supply house actually charges you, the materials, the labor hours, the permit, disposal, the first year's tune-up, a reserve for callbacks and your overhead, with a margin on top. Then check it against what other shops charge: Housecall Pro's customer data puts a 2.5-ton heat pump system at $6,200 to $11,275 installed and a 3.5-ton split system at $6,950 to $12,850.² The quote itself names the model numbers and the AHRI match, the scope and what's excluded, the permit, who registers the warranty, your labor warranty, the tune-up, and the deposit and payment terms, ideally as two or three options side by side. And in 2026, delete the federal tax credit line: 25C ended for equipment placed in service after December 31, 2025.²²

The template is a proposal you can fill in and hand over. Page 1 is what you found and the options table (good, better, best). Page 2 is the scope, the exclusions, the permit, warranty and payment terms, and the signature block with the federal cancellation statement. Appendix A is the FTC's notice of cancellation in two copies, and Appendix B is your pricing worksheet, which stays with you. Every number in it is marked as an example.

Why this job. When we read two years of posts from new HVAC company owners, the first system quote was where the numbers ran widest and the job was least familiar.¹ One post sums it up. A newly opened one-man shop near Lexington, Kentucky, quoted $19,500 and wrote: "My price is at 19,500. They act like that's insane. What would you charge?"³ The pages that rank for "hvac proposal template" are mostly design templates and software vendors' sign-up pages. Their titles and snippets promise a layout, not what the job sells for or what has to be on the paper in 2026.

What a system replacement sells for: the measured range

The best public price data I know of is Housecall Pro's pricing page. It's built from "3,648,131 reported HVAC service entries across 102 service categories from Housecall Pro customers over a 12-month period, ending September 2026", with outliers filtered out.² These are the install rows it says come from that customer data:

Three cautions. The data comes from Housecall Pro's own customers, so it's self-selected. The page notes that "System size alone doesn't set the price", because brand, efficiency and what's included vary. And its furnace install row ($2,800 to $7,500) is marked as a third-party national average, not their data, so I left it out.²

The same page splits the 2.5-ton heat pump by region. It doesn't say which states sit in which region:

Owners who state their own install prices are few, and their numbers sit inside those ranges. A three-man family crew south of Boston: "it's rare that we do a full system replacement under $10,000", and an easy basement job is "around 8-9000 just for ease of install".⁴ A side-job installer: "If I do a full system replacement for 10k equipment is usually around 5".⁵ A contractor pricing a single-zone Fujitsu ductless job showed his math: "My cost on all above $2307,00", and "Total installed chat $4080.00".⁶

One homeowner posted a whole contractor quote for a 4-ton replacement on existing ducts in July 2025, and it's a good model of the format. Four options, each with the model number of every piece: a Carrier Comfort air conditioner with an 80% furnace at "$ 9,895.00 less $300 utility company rebate", a Trane version at $10,255, and two hybrid heat pump systems at $13,920 and $16,940 before state and maker rebates.⁷ That's a real shop's pricing, from one quote in one market.

Now look at the $19,500 again. It wasn't a changeout. "No existing system upstairs. I'm running new duct and everything. It's a 2 ton heat pump. Attic has reasonable access but 2 of 7 rooms will be difficult to add duct." The one answer it got before moderators removed the post: "We'd charge that just for the ductwork."³ Compare a quote with the row for the same job, not the cheapest row on the page.

Why your equipment costs more than the shop down the road

A new company often pays more for the same box. An owner who had just opened accounts: "I just started my company and I got accounts opened for different brands and most of their wholesale pricing has been good but Carriers is just insane. They want to charge over $7000 on a 1.5 ton HP from their least expensive "tier" comfort and that just the outdoor unit." A distributor's rep answered: "Wholesale guy here. Standard non dealer pricing. We do it on purpose to not sell to you lol." He added: "If you were to become a dealer, it wouldn't be anywhere close to that."⁹ Another owner's fix was a different supplier: "I can get a ICP carrier brand unit which looks like a carrier without the label for 1.5T 2.2K look for a provider that wants your business."⁹

Here's what that does to a quote. The dealer down the road sells the job at the market price. You can't charge more for the same system, so the extra equipment cost comes straight out of your margin. In the worked example below, a 3-ton changeout priced at $9,495 makes a 15% margin. Put $1,500 more on the equipment line (an example figure) and the same $9,495 loses $75. Keeping 15% would take a price of $11,260: the top of the measured range for a 2.5-ton heat pump, and the upper half for a 3.5-ton system.

So, on the next quote:

• Price the equipment at what you actually pay, not what you think a dealer pays. Then see where the total lands.
• Get prices from two or three supply houses and brands before you commit to one. Quote the brand where your price is good.
• Put a "price good until" date on every proposal. Supply-house prices move, and a quote that sits for two months can go underwater.
• If one brand only sells to you at non-dealer prices, don't try to win that customer on that brand. Offer what you can buy well.

How to price an HVAC install, line by line

Here's every line I'd put in the build, with an example for a 3-ton AC and gas furnace changeout on existing ducts. The numbers are made up to show the arithmetic, so swap in yours. Appendix B of the template has the same lines for all three options.

That lands inside Housecall Pro's measured ranges, and just under the $10,000 the Boston-area crew rarely goes below. If your total comes out far under the range, check the labor first. The easy lines to forget are the second person, the drive to pick up the equipment, the start-up and the paperwork.

A few notes on the lines:

• Labor rate. The US median wage for an employed HVAC mechanic was $29.33 an hour in 2025.¹⁵ That's pay before payroll tax, comp and insurance, so a helper costs you more than that, and your own hour has to carry overhead and profit on top.
• Disposal. EPA's rule: "Any person servicing, installing or disposing of stationary appliances (except the disposal of small appliances) must be a section 608 certified technician."²⁵ Recovering the old charge is part of the job, so price the time.
• Warranty reserve. A one-year labor promise means free trips. One owner's warning to people going out on their own: "Think you'll be getting paid for every call back and component that fails under warranty? Nope."¹¹
• The tune-up. Some owners put the first year's maintenance in every install price. "I always include one year of maintenance on new installs," one wrote in a homeowner's quote thread.⁸ It costs you a visit, and it puts you back at the system in the first year.
• Margin. Housecall Pro quotes ACCA as recommending "a 10% net profit to sustain growth", with the average residential contractor netting about 5%.² A 15% margin isn't the same thing as a 15% markup; our contractor markup guide has the arithmetic and a chart.

One more reason to do the build on paper. A young owner found out after his first big job, a heat pump and duct system: "I underbid the job and barely made a profit."¹⁰

Size it from a load calculation, not the old unit's nameplate

The model code doesn't let the old unit decide. IRC M1401.3: "Heating and cooling equipment and appliances shall be sized in accordance with ACCA Manual S or other approved sizing methodologies based on building loads calculated in accordance with ACCA Manual J or other approved heating and cooling calculation methodologies."¹⁶ Manual J is the heat loss and heat gain calculation for the house. Manual S is picking equipment whose rated capacity fits that load. The code allows some room above the load for multistage and variable-speed equipment and when no unit fits both the total and sensible load.

Why the nameplate fails:

• The old unit's size is what someone picked 15 or 20 years ago, and you don't know how they picked it.
• The house has changed since. New windows, attic insulation, a finished basement or an addition all move the load.
• Oversizing costs the customer. ENERGY STAR tells homeowners that a system that's too large "may not keep your home comfortable because of frequent on/off cycling, causing humidity control problems", that oversized units "tend to have shorter lives" because they short-cycle, and to make sure the contractor sizes it with "Manual J".¹⁸ Your customer may have read that page.
• Heat pumps add the heating side. Mass Save's sizing bonus wants heat pumps "sized to meet 90-120% of the total heating load at the outdoor design temperature, per ACCA Manual J", and a copy of the calculation with the application.²⁰

Nobody in the new-owner threads we read asked about Manual J.¹ That's the reason it's here. One newly licensed tech who had never installed a whole house said "I feel like I can size a house for the right equipment but I have no idea how to build or layout the duct system".¹⁴ Whether your permit office wants to see a load calculation on a straight changeout depends on the town, so ask. Put the result on the proposal anyway (the template has a line for it). It's the strongest answer you have when a cheaper quote has a bigger unit. Our HVAC installation checklist covers when a whole-house calculation is enough and when you need room by room.

The AHRI match, utility rebates and the tax credit in 2026

Put the AHRI reference number on every option

A split system's efficiency rating belongs to the combination, not the outdoor unit alone. AHRI's guidance to homeowners: "Split air conditioning and heat pump systems (with indoor and outdoor units) need to be properly matched", and the rating mark "is only valid for a split system if both the indoor unit and outdoor unit are properly matched". It tells them to "ask your installer for an AHRI Reference Number or an AHRI Certificate of Certified Product Performance", and notes that "the certificate can be used in some areas to obtain a rebate from your utility or local municipality".¹⁹ Look the match up in the AHRI directory before you quote. If the coil you planned to reuse isn't on a certificate with the new condenser, quote a new coil.

Rebates: show them, don't promise them

Rebates are local, and they change. One example from our list: Mass Save in Massachusetts pays 2026 whole-home heat pump rebates of $2,650 per ton up to $8,500, with tons "calculated based on AHRI cooling capacity divided by 12,000 BTUs". The installer has to be in the Mass Save Heat Pump Installer Network. Since October 1, 2026 the application needs a nameplate photo showing the serial number. For whole-home projects installed from January 1, 2027, the rebate drops to "$2,350 per ton, capped at $7,500".²⁰ That last line matters for a quote written in December. For federally funded state rebates, the Department of Energy says only that "Home Energy Rebates are now available in select states" and to contact the state energy office.²¹

On the proposal, show the price before rebates, the rebate you expect as a separate line, who files it, and that the price doesn't change if a program turns it down. The template words it that way.

The federal tax credit is gone for 2026 installs

The IRS lists the energy efficient home improvement credit (25C) as one that "will not be allowed for any property placed in service after December 31, 2025". The residential clean energy credit (25D), which covered geothermal heat pumps, "will not be allowed for any expenditures made after December 31, 2025", and an expenditure counts as made when the installation is completed.²² The IRS's own 25C page still reads "You can claim the credit for improvements made through December 31, 2025."²³

Quotes written before 2026 carried the line. The July 2025 quote above said "*Heat pump system qualifies for Federal Tax credit 25C -30% of job cost up to $ 2,000".⁷ That was true for a 2025 install. Put it on a quote in 2026 and you've promised a customer money they won't get. The template says plainly that the credit ended and that you don't promise any tax credit.

Good, better, best: options on an HVAC replacement quote

Two or three options let the customer choose a price without you cutting one. Housecall Pro's page suggests tiers by efficiency and by "Single-stage, two-stage, or variable-speed" equipment.² The quote the homeowner posted did exactly that, from a Carrier Comfort air conditioner with an 80% furnace up to an Infinity inverter heat pump with a variable-speed furnace.⁷ A layout that works:

• Good: like for like. Same type of system, single-stage, the efficiency your area requires, the same capacity only if the load calculation says so.
• Better (mark it recommended): the one you'd put in your own house. Often two-stage, or a heat pump with the furnace as backup.
• Best: variable-speed, the quietest and most even system, at the top of the range.
• Add-ons, separately: a new line set instead of flushing the old one, a media filter, a surge protector, a condensate pump, return changes. The customer ticks them.

Every option gets the same scope, warranty and terms, and its own model numbers, capacity, efficiency, refrigerant, AHRI number and price. Write the refrigerant on each one. EPA's May 2026 rule "allows the inventory of residential and light commercial air conditioning and heat pump equipment that was manufactured in the United States or imported into the United States before January 1, 2025, to continue to be installed", so an R-410A system can still show up as the cheaper option.²⁴ Say which refrigerant it uses, so the customer knows what they're choosing.

What the HVAC quote must include

This is the checklist behind the template. Each line is there for a reason you'll meet on a callback or in a dispute.

Register the warranty, and say who does it

Makers cut the parts warranty when nobody registers the equipment. Goodman: "If the unit is not registered within the 60-day window of the installation date, the air conditioner's applicable warranty period is 5 YEARS", against up to 10 years if registered in time; residents of California, Florida and Georgia don't need to register.²⁷ Carrier: "If you register after 90 days, the standard 5-year parts warranty applies with no labor coverage." Its 5-year parts plus 3-year labor option needs a dealer who has signed up for that program.²⁶

Owners see the cost years later. A self-employed tech: "it surprises me how many times I look up a warranty on a system to see that it was never registered and it's always after 5 years but before 10 when the shit fails." The invoices, he added, "always say clear as day 10 year warranty".¹² A company that bought another shop: "all of their sales contracts stated there were 10 year warranties, but it was left up to the homeowners to register it. We ate the cost on a lot of parts."¹² If your quote says 10 years, register it yourself and write the confirmation number on the invoice.

Your labor warranty

Owners who state one give a year. A contractor's own quote line: "register the warranty and one year no charge labor on any install or warranty issues".⁶ The side-job installer: "register their warranty and give them one yr labor guarantee".⁵ Say what happens after the year: the template has a blank for your labor charge on a warranty part. If you become a dealer, read the dealer agreement before you charge labor on warranty work. One tech warned: "If it's under warranty and you charge labor, carrier can revoke your dealer status."¹³

The contract rules: federal, then your state

The federal Cooling-Off Rule. A sale of $25 or more made at the buyer's home counts as a door-to-door sale, "including those in response to or following an invitation by the buyer".²⁸ So a replacement the customer called you about, signed at the kitchen table, is covered. You have to:

• Put this statement next to the customer's signature in bold, at least 10-point type: "You, the buyer, may cancel this transaction at any time prior to midnight of the third business day after the date of this transaction. See the attached notice of cancellation form for an explanation of this right."
• Hand over the "NOTICE OF CANCELLATION" form, filled in, in two copies, and tell the customer about the right to cancel out loud.
• If they cancel, refund their payments within 10 business days.²⁸

Two exclusions matter in HVAC. A repair visit the customer asked for is excluded, but selling them "additional services or goods" on that visit, such as a new system, is not. And a true emergency (no heat in January, say) can be excluded if the customer started the contact and gives you "a separate dated and signed personal statement in the buyer's handwriting" describing the emergency and waiving the three days.²⁸ The rule also doesn't cover a sale you close at your own permanent place of business.²⁹ The template has the statement and both copies of the notice.

Your state. On top of the federal rule, many states set what a home improvement contract must say, how big the deposit can be, and their own cancellation wording. Massachusetts, for example, caps a deposit at "the greater of one-third of the total contract price or the actual cost of any materials or equipment of a special order or custom made nature", and the contract has to tell the homeowner about permits and that pulling them is the contractor's job.³⁰ We've written contract pages for the states on our list: Massachusetts, New Jersey, Virginia, Minnesota, Louisiana, Colorado, Iowa, New York, Idaho, Connecticut, Nebraska, Utah and Arkansas. They were written for home improvement work in general. If your credential is a mechanical or HVAC license rather than a home improvement registration, ask your board whether the home improvement contract law reaches your installs. The federal rule applies either way.

When the customer says the price is insane

When a customer balks the way the Kentucky owner's did, work through this before you drop the number:

1. Check the job you're comparing against. His was a new system in an upstairs with no ducts, which is two jobs: a heat pump and a duct system. The one answer he got said the ductwork alone could cost that.³ If yours is a changeout on good ducts in a basement, the measured ranges above apply. If it's an attic, it costs more. The Boston-area crew: "Is it in a crawl space attic? If yes, it's gonna be more money."⁴
2. Ask what they're comparing. A number from a neighbor, a website or another quote? If it's another quote, ask whether it has model numbers, the same capacity, the permit, registration and a labor warranty. If the scope differs, you aren't comparing prices.
3. Walk them through the lines. Customers see a total. Show the scope, the exclusions and what's included that they didn't think about: the permit, the registered 10-year parts warranty, the labor year, the first tune-up.
4. Move them down an option, not your price down. If the budget is real, the Good option or fewer add-ons is the answer. Cutting the price of the same scope teaches them that your first number wasn't real.
5. Let it go if it doesn't fit. The first-install mistake we saw new owners post about was an underbid, not an overcharge. If you priced from your costs and you're inside the range for that scope, the job that doesn't close at that price isn't one you can afford.

Something you can say at the table: "That's the price for this system, done this way, with the permit, the registration and a year of labor. If it's more than you want to spend, here's what changes in the lower option. What I won't do is the same job for less, because that money comes out of the install."

How to use the proposal template

1. On the survey, fill in "What we found": the old equipment, the ducts, the electrical, the gas, the drain and the line set. Do the load calculation and write the result on the sheet.
2. Fill in Appendix B for each option from your own costs. Check each total against the measured range for that size and scope.
3. Look up the AHRI reference number for each option and write in the model numbers, capacity, efficiency and refrigerant.
4. Tick the scope lines that apply, strike any exclusion that doesn't, and fill in the permit, warranty, deposit and valid-until blanks. Check your state's contract page for its deposit limit and wording.
5. Present the options. When the customer chooses, fill in the acceptance block, both sign, and fill in and hand over both copies of the notice of cancellation.
6. After the install, close it out with the HVAC installation checklist: start-up readings, the AHRI certificate, the permit, and warranty registration before the maker's deadline. The HVAC invoice template covers the final invoice with the deposit credited.

Where Deepsel fits

The template is a document on purpose, so it works on your first quote. If you'd rather build and send quotes from your phone, Deepsel handles the customer side. An estimate holds several options (good, better, best), you mark one as recommended, and lines can be optional, so the customer ticks add-ons on the approval page. Price book items carry a price and your cost, and while you build an estimate the owner sees the option's total cost, profit and margin, so you see the margin before you send it. Your shop-wide terms text is copied onto each estimate and shows above the signature, which is where your standard exclusions and warranty lines go, and each estimate carries a valid-until date (30 days unless you change the shop setting). The customer picks an option, ticks add-ons and approves with their name and an on-screen signature. If you take card payments through Deepsel, they can then pay a deposit (a percent or a fixed amount) by card, and it's credited on the final invoice. On Pro, estimate templates save a whole good-better-best changeout so the next one starts filled in, with price book lines taking today's price. Customer equipment records hold type, brand, model, serial, year, filter size, location, tonnage, refrigerant, SEER2 or AFUE, a nameplate photo and a note, plus rows you name yourself. What it doesn't do: no load calculation, no AHRI lookup, no permit field, no install date or warranty registration field on equipment (add a row of your own), and it doesn't produce the FTC's two-copy notice of cancellation, so for a sale signed at the customer's home, hand over the paper notice from the template too. The Free plan covers 30 estimates and 30 invoices a month for your whole team; Pro is $29 a month for unlimited estimates and invoices. Details are on the pricing page.

Frequently asked questions

What should an HVAC proposal include?

For a system replacement: your license number and contact details, the customer and install address, what you found (the old equipment and the load calculation result), one to three options with the model number of every piece, the capacity, efficiency, refrigerant and AHRI reference number, the price of each option before rebates, the scope that comes with every option, what isn't included, who pulls the permit, who registers the manufacturer warranty and by when, your labor warranty, the first year's tune-up if you include it, the deposit and when the balance is due, the date the price expires, and both signatures. If the customer signs at home and the price is $25 or more, the FTC's Cooling-Off Rule also wants a cancellation statement next to the signature and a notice of cancellation in two copies.

How do you price an HVAC install?

Add up the equipment at your own supply-house cost, the materials, the labor hours times your loaded hourly cost, the permit, disposal and refrigerant recovery, the first year's tune-up and a reserve for warranty callbacks. Add your share of overhead, then divide by one minus your target margin (for a 15% margin, divide by 0.85). Then check the total against what shops charge for the same size: Housecall Pro's customer data puts a 3.5-ton split system at $6,950 to $12,850 installed and a 2.5-ton heat pump system at $6,200 to $11,275. If you land far under, recheck your hours and your materials list.

What is the average markup on HVAC equipment?

There's no measured average I'd trust. Owners on Reddit give pieces of it. A side-job installer wrote "If I do a full system replacement for 10k equipment is usually around 5", so equipment was about half his price. A contractor pricing a single-zone ductless job had $2,307 in equipment and materials and quoted $4,080 installed. I'd price from your own costs and a target margin rather than a markup on the box, because labor, the permit, the tune-up and callbacks all ride on the same job. Our contractor markup guide shows how a markup turns into a margin.

How much does it cost to replace an HVAC system in a 1,500 square foot house?

Square feet don't set the size: the load calculation does, and two houses of 1,500 square feet can need different tonnage. Once you know the size, Housecall Pro's customer data for the 12 months to September 2026 gives these installed ranges: a 2.5-ton heat pump system $6,200 to $11,275, a 3.5-ton split HVAC system $6,950 to $12,850, a 4-ton split AC system $5,500 to $11,965. Its regional table for the 2.5-ton heat pump runs from $4,960 to $10,780 in the Northern Rockies and Plains up to $7,500 to $14,000 in the Northeast. It's data from Housecall Pro's own customers, so it's a benchmark, not a survey.

Is the 25C tax credit still available for HVAC in 2026?

No. The IRS says the energy efficient home improvement credit (25C) "will not be allowed for any property placed in service after December 31, 2025", after the July 2025 tax law moved its end date up. The residential clean energy credit (25D, the one geothermal heat pumps used) ended for expenditures after the same date. Take the tax credit line off any old quote template. Utility rebates and some state programs still exist, so check what applies at the address.

Is an HVAC quote template the same as an estimate template, a bid template or a proposal template?

Close enough. In home service work, quote and estimate both mean the price you're offering. Proposal usually means a quote with options and terms the customer signs, which is what a system replacement needs. Bid is used more for commercial and new construction work priced from plans against other contractors. Whatever you call it, once the customer signs it, it's your contract, so the scope, the exclusions and the payment terms matter more than the name at the top.

Do I need a Manual J load calculation for a like-for-like changeout?

The model code says equipment is sized that way: IRC M1401.3 sizes heating and cooling equipment by ACCA Manual S from loads calculated with ACCA Manual J or another approved method. Whether your permit office asks to see one on a straight changeout varies, so ask. Rebate programs may ask anyway: Mass Save's heat pump sizing bonus needs a copy of the heating load calculation. And the old unit's nameplate only tells you what someone picked years ago, for a house that may since have new windows, insulation or an addition.

How much deposit should I take on an HVAC install?

Enough to cover the equipment you buy before the job, inside your state's limit. Massachusetts caps the deposit on a home improvement contract at the greater of one-third of the price or the cost of special-order equipment; our state contract pages list the other states' rules. If the sale falls under the FTC's Cooling-Off Rule and the customer cancels within three business days, you refund the deposit within 10 business days of their notice, so think twice before ordering equipment you can't return inside that window.
