HVAC ESTIMATE TEMPLATE
Free HVAC estimate template
An HVAC estimate with the equipment named — make, model, tons, SEER2, refrigerant — the matched indoor unit, labor, permit and haul-away on their own lines, a higher-efficiency option, and a deposit that orders the equipment. Free in Word and PDF, with every line explained.
Word and PDF · Free · No email, no sign-up
The short answer
An HVAC estimate names the equipment — make, model, tonnage, SEER2 and refrigerant for the outdoor unit; make, model and AFUE or HSPF2 for the furnace or air handler; “matched” written on the line — and prices labor, the permit and the old system's removal separately, so the homeowner can compare your estimate with the other two on the kitchen table.
Offer the step-up as an option on the same sheet: the two-stage or higher-SEER2 system as “+$X” on its own line. One estimate with an option gets a decision; two estimates get a third phone call.
Around that go your business and license details, the customer and the address, the estimate number and the date it holds until — shorter than usual, because equipment prices move — the day and the technicians, what's included and what isn't (ductwork, electrical, drywall), and how to pay.

LINE BY LINE
What goes on an HVAC estimate
Every line on the template, in order, and what to write on it.
| The line | What to put there |
|---|---|
| Business name, contact, license and EPA certification | Your trading name, phone, email and address, your state HVAC license number and your EPA Section 608 certification — the homeowner is checking all three. |
| Estimate number, date and valid-until date | A number that never repeats, the date, and the date the price holds until — 14 days is common on replacements, because equipment prices move. |
| Prepared for and the system in one line | The customer and the address, then the system: what's being replaced or repaired, tons, fuel and stages, the day and the technicians. |
| The equipment, named | Make, model, tons, SEER2 and refrigerant for the outdoor unit; make, model, BTU and AFUE (or HSPF2 for a heat pump) for the indoor unit, with “matched” on the line. This is the line the three estimates get compared on. |
| Line set, pad, electrical and drain | What you flush and what you replace: line set, pad, disconnect and whip, drain line and float switch — so the price covers the whole install, not just the boxes. |
| Labor | Technicians × days, with what the day includes: remove the old system, set and connect the new one, evacuate, charge, start up and test. |
| Permit, inspection and haul-away | The mechanical permit and inspection on one line, the old system's removal and refrigerant recovery on another — two costs the homeowner should see are real and covered. |
| The option | The higher-efficiency or two-stage system as “+$X” on its own line, so the base price stays clear and the upgrade is a decision, not a second estimate. |
| Tax, total, deposit and how to pay | Sales tax where your state charges it (often on the equipment), the estimated total, the deposit that orders the equipment, when the balance is due, and how to pay. |
STEP BY STEP
How to write an HVAC estimate
From the load calculation to an estimate on the homeowner's kitchen table before the other two companies have left the driveway.
Put your details at the top
Business name, phone, email, address, your state license number and your EPA 608 certification. Save the file once with these filled in.
Number it, date it, set a short valid-until date
The next number in your series, today's date and the day the price stops holding — 14 days on a replacement, because equipment prices change.
Size the system and name the equipment
Run the load calculation, then write the outdoor unit's make, model, tons, SEER2 and refrigerant and the matched indoor unit's make, model, BTU and AFUE or HSPF2 — one line each.
Price the install around the boxes
Line set, pad, whip and drain on one line; labor by technicians × days; the permit and inspection; the haul-away and refrigerant recovery. Then the upgrade as an option.
Add tax, total it, name the deposit
Sales tax where your state charges it, the estimated total, and the deposit that orders the equipment and books the day.
Write what's included and how to pay
The system, permit and start-up in; ductwork, electrical panel work and drywall out. The deposit, when the balance is due, payment plans if you offer them. Send it before you leave the driveway.
How HVAC estimates win the job
Name the equipment. A homeowner replacing a system gets two or three estimates and compares them line by line. “3-ton 15.2 SEER2 condenser, make and model, R-454B” is a line they can compare; “new AC system” isn't — and the estimate that names it is the one they trust with the number.
Offer the step-up as an option, not a second estimate. The two-stage or higher-SEER2 system as “+$X” on the same sheet turns the upgrade into a decision the customer makes at the table. Two separate estimates turn it into a third phone call.
Flat-price the install, hourly for diagnosis. HVAC pricing has the US ranges for tune-ups, repairs and installs and the service-call fee; a replacement estimate is a flat price with the equipment and the labor on separate lines, and a diagnostic visit is the service-call fee plus the repair as a separate estimate.
Name the refrigerant and the rules around it. In the US, anyone who handles refrigerant must hold EPA Section 608 certification (a federal rule), new residential systems made since 2025 use lower-global-warming refrigerants such as R-454B or R-32 rather than R-410A under the EPA's refrigerant transition rules, most states license HVAC contractors, and nearly every city or county requires a mechanical permit to replace a system. Put the refrigerant on the equipment line and the permit on its own line, and check your state and city for the rest.
Rebates on their own line. If your utility offers a rebate for the model you're installing, show it as its own line — either taken off the price or marked as the customer's to claim — and check the rebate's rules before you promise it.
Tax. In the US, whether sales tax applies to an HVAC replacement — the equipment, the labor, both or neither — depends on your state and sometimes on how the estimate is written: in Texas, for example, a customer sees sales tax on a residential job's materials only when the estimate separates materials from labor. Keep equipment and labor on separate lines and check your state's revenue department or your accountant. Outside the US the rule is the other way around: in Australia and New Zealand a GST-registered business gives a consumer a price that includes GST, and in the UK and EU a VAT-registered business shows the VAT and quotes consumers a price with it included. Confirm the details with your accountant.
Send it from Zarla and get it accepted online
A Word estimate is a fine way to start. The slow part is everything after you send it: waiting for a reply, wondering whether they opened it, and retyping every line into the invoice when they say yes.
If you build your HVAC website with Zarla, quotes are in the same dashboard. Build the quote from your own price book — one price, or up to three options side by side with the one you'd pick marked Recommended, and any line as a checkbox extra. Send it as one link, by email. Your customer picks an option, ticks any extras, types their name to accept, and gets a copy; Zarla drafts the invoice for exactly what they chose, with any deposit you asked for, and the job moves to Won. The quote template is already in your brand: your website's logo, colors and fonts, set once for every quote and invoice. On a paid plan, with your Stripe account connected, that invoice carries a pay-now button, so the deposit comes in as soon as you send it.

HVAC estimates: common questions
Your business, contact, license and EPA 608 details; the customer, the address and the system in one line; an estimate number, the date and a short valid-until date; the outdoor unit by make, model, tons, SEER2 and refrigerant; the matched indoor unit by make, model, BTU and AFUE or HSPF2; line set, pad, electrical and drain; labor; permit and inspection; haul-away and refrigerant recovery; the upgrade as an option; tax where it applies, the estimated total and the deposit; then what's included, what isn't, and how to pay.
An estimate is your best calculation of what the job will cost, given what you can see today; the final price can move if the work turns out different. A quote (or a fixed price) is the price you will charge for the work described. A bid is a quote submitted against someone else's specification, usually in construction. Say which one your document is in its title.
Yes — on one sheet. The base system is the estimate; the two-stage or higher-SEER2 system is an option line showing the difference. Three full estimates make the homeowner do the arithmetic; one estimate with options makes the choice obvious, and most customers pick the middle.
Fourteen days is common on a replacement — equipment prices and availability move faster than labor rates — and 30 days on repairs and small jobs. Print the date: a customer who comes back after it can be re-quoted at today's equipment price without an argument.
Enough to cover the equipment you order — commonly a third to a half of a replacement — with the balance due at start-up. Repairs under a few hundred dollars usually take no deposit; the service-call fee is paid on the visit.
Most HVAC companies estimate a replacement free and charge a service-call or diagnostic fee for a repair visit, often waived if the customer books the repair. Say which before the visit, and show the fee on the estimate as waived when it is.
Yes. The HVAC estimate template on this page downloads free as a Word document and a PDF — no email address, no sign-up. Edit it in Word or any app that opens Word documents, or print the PDF and fill it in by hand.
Not from a Word file — the customer replies by email or phone, and you type the job into an invoice later. To get a yes in one tap, send it from quoting software. If your HVAC website is on Zarla, the quote tool is in the same dashboard: your customer opens one link, picks an option, ticks any extras and types their name to accept, and Zarla drafts the invoice for what they chose — which, on a paid plan with Stripe connected, carries a pay-now button. Jobber, Housecall Pro, Wix and Squarespace send quotes customers accept online too.
