HVAC proposal template (contractor-tested)

Note on this template. This isn't a Word document you download. It's the actual structure that survives the most field testing from real HVAC contractors. Copy it into whatever tool you write proposals in today — Word, Google Docs, the back of a napkin — and you'll have a proposal that's better than 80% of what gets emailed to homeowners.

The template below is six sections. None of them should take more than two or three sentences. If yours run longer, you're writing more than the customer will read.

A separate guide covers how to write each section well and what to leave out. This guide is just the structure.

you accept.]


ACCEPTANCE

By signing below I accept this proposal and authorize
the work described.

Signature: _______________________  Date: __________


[Your company name] • [Your phone]
License # [your license]

That's the whole thing. One page. Maybe one and a half if you have many line items.

How to fill each section without overthinking it

The point of having a template is that you stop making creative decisions every time you write a proposal. Below is how to fill each section quickly.

The header

Set this once, save it, and never look at it again.

• Company name, address, phone, email, license number
• Use the same logo and typeface every time
• License number isn't optional in most US states. Print it.

Cover paragraph

The fill-in-the-blanks version that works for nearly any repair:

"Hi [first name] — thanks for [having me out / your call]. As we discussed, [one-sentence summary of the problem]. This proposal covers [what you're going to do]."

That's it. No "thank you for considering [Company Name] for your HVAC needs." Just confirm you understood what they need.

Scope of work

Three sentences max. The pattern:

"We will [primary action — the main repair or install]. Then we'll [secondary actions — verifications, checks, anything you do to confirm the fix held]. [Optional: anything you'll discuss before doing it.]"

Example:

"We will install a new 1/3 HP condenser fan motor and replace the dual run capacitor. Then we'll verify suction and discharge pressures and check the contactor for pitting. If the contactor needs replacing we'll let you know before we install it."

Itemized estimate

Show every part with a real description, a real quantity, and a real unit price. Round nothing.

Don't:

Repair                     1    $589.00    $589.00

Do:

Dual run capacitor 45/5 MFD                1     $149.00    $149.00
Condenser fan motor 1/3 HP, 1075 RPM      1     $389.00    $389.00
Labor (1.5 hr @ $95/hr)                  1.5     $95.00    $142.50
─────────────────────────────────────────────────────────────────
                                  Subtotal              $680.50
                                  Tax (6.25%)            $42.53
                                  TOTAL                 $723.03

The detailed version reads as transparent. The vague version reads as hiding something.

Terms

This is where most contractors copy a page of legal language from somewhere and get it wrong. The shortest version that does the actual work:

"All parts we install are warrantied for 90 days. Labor on the same repair is included for 30 days. If we discover additional issues during the work that would affect the price by more than $50, we'll stop and discuss them before continuing."

"Payment is due upon completion. We accept cash, check, Visa, MasterCard, and Discover."

Two paragraphs. That's it. Have an attorney review the warranty language if you're worried about it. Don't copy the warranty terms of the part manufacturer — those don't apply to your labor.

Acceptance

Make it easy for the customer to sign.

For paper proposals: a signature line and a date.

For digital proposals: a typed signature box with a checkbox confirming they've read the terms. Both digital methods are legally sufficient for residential HVAC work in nearly every US state, but check your state's specific rules if you're doing significant capital work like full system installs.

Footer

Just your company name + phone + license number. Makes the proposal self-contained — if a customer prints it out and hands it to someone else, they can still reach you.

Where to keep the template

A few places work:

1. A saved Google Doc you copy each time. Simplest. Has the downside of "copy → paste → edit → forget to update the customer name in three places."
2. A Word document with merge fields. Better than 1 if you do enough proposals to justify the setup. Real merge fields hate you back when you change the wording.
3. A proposal tool. Houses the template once, fills in the customer info from a single form, generates a PDF. This is what software like Quazlow does.

The right answer is whichever you'll actually use. A template you maintain is better than a tool you abandon.

When the template doesn't fit

Some jobs don't fit a six-section template:

• Full system installs. Add an equipment specification section between scope and line items.
• Maintenance plans. Don't use this template at all — use a contract.
• Commercial work. The acceptance terms get longer; the scope often runs to multiple pages.

For everything else — service calls, single-part replacements, common repairs — six sections is enough.

The faster way

If filling out a template still takes 20-30 minutes per proposal, you're spending too much time on something a tool can do in 60 seconds.
