11 Questions Every HVAC Proposal Software Vendor Should Answer in the Demo

You're 3 demos in, and every tool on your shortlist looks the same. Each one has clean screens, the same row of options, and a dashboard full of green arrows, and every vendor says onboarding is quick. Some HVAC proposal software helps your comfort advisors sell. Some only looks good on a conference room screen. The difference shows up at the kitchen table, so here are 11 questions every vendor should answer before you sign.

In a 2025 survey of 422 homeowners, only 31% ranked upfront cost as their top priority, so a tool that only shows a price leaves most of the decision out.

Bring the same sample home to every demo and make each vendor build on it live: say, a 19-year-old AC and heating system, a 3-ton load, and an upstairs bedroom that never cools.

1. What does the homeowner see first?

The homeowner should see what the technician found in this house, with photos, tied to each option. If all they see is a total, everything after becomes a defense of it.

Make them show you: "Open a finished proposal on a tablet and show me the first screen exactly as the homeowner sees it."

Good answer: Findings from this home in plain language, tied to what the homeowner said, because feeling heard builds trust.

2. How fast can a seller build 5 options in the home?

A seller should build 5 options in minutes. If it takes 15, they lock in one system early and keep talking to buy time, and one option is an ultimatum. Several real options let the homeowner shop. Asked what stood out about the contractor they chose, 36.2% of homeowners said the contractor gave them control over the decision.

In ACCA's study, contractors showing 4 or more options averaged a 52% close rate, versus 42% for those showing 1 to 3. Proposal data points to roughly 5 to 6 for HVAC.

Make them show you: "Build 5 priced options on my sample home while I time it, then change one."

Good answer: Options built in minutes and modified in seconds, pulled from your pricebook. Each step up is better on what homeowners weigh.

3. Can the homeowner toggle add-ons live?

Yes, and "What if we add the air cleaner?" should change the price and monthly payment on screen. 32.9% of homeowners valued proposals that let them add or remove items, and a tablet proposal can do that live where a printed bid can't.

Make them show you: "Hand me the tablet so I can add a surge protector and a 10-year labor warranty, then remove one."

Good answer: Every number updates without anyone doing math.

4. Does it lead with financing every time?

It should, on every option, without the seller having to remember. In ACCA's Contractor of the Future study, contractors offering financing averaged a 49% close rate, versus 38% for those that didn't, yet only 37% offer it on every job. Contractors who lead with a monthly payment instead of the total finance 42% of sales on new and replacement systems, versus 21% when they lead with total price.

Make them show you: "Open the proposal the way a seller would. Does financing lead on all 5 options by default? Now add an add-on and show me it carry through."

Good answer: Financing leads by default, every time, on every option. Ask whether the price can change by payment method, and whether financing fees can be recovered.

5. Can the homeowner sign on the spot?

Yes, the homeowner should be able to sign at the table, and the signature should capture the chosen option and leave them a clear record. The FTC's Cooling-Off Rule covers many in-home sales, so check current FTC and state rules for cancellation notice.

Make them show you: "Sign my sample proposal and show me what the homeowner receives."

Good answer: The homeowner can see what they chose and what they signed.

6. Does the quote stay live for follow-up?

The quote should stay live after the seller leaves, because many replacement deals aren't decided at the table. Software that emails a PDF and forgets pushes follow-up into personal text threads nobody else sees.

A live quote is a link the household can reopen, with the same options and toggles. Prompt follow-up stood out to 39.1% of homeowners, and a quote that can't carry the decision tends to stall.

Make them show you: "Send the sample quote to my phone. I'll open it and change an option. Show me what the seller sees."

Good answer: The seller sees the open in real time and what was viewed, texts come from a business number, and a manager sees every open quote in one list.

7. What does a manager see?

A manager should see how each seller compares, because a company close rate hides the gap between them.

Make them show you: "Show me how my sellers compare, then open one proposal and show me what the homeowner did."

Good answer: Each seller's numbers side by side, a score on each proposal, and a record of what the homeowner looked at.

8. How does it integrate with our field service software?

A sold proposal should land in your field service software with no retyping. If someone has to retype it, they'll skip it on a busy Friday.

Make them show you: "Sell my sample proposal, then show me where it lands in our field service software."

Good answer: The sale appears with no retyping, and the vendor can tell you which platforms it supports.

9. How are your interests aligned with ours?

Find out whether the vendor wins only when you win.

Make them answer: "Am I limited in who can use it? If our results slide, do you feel it too? Or will I only hear from you ten months from now, when the contract is up for renewal?"

Good answer: A worked example in writing at your sales volume, and a plain explanation of how their incentives line up with yours.

10. What does onboarding look like?

The plan should run week by week, with named owners and time for sellers to practice. A tool your comfort advisors abandon in week 3 costs more than the license.

Make them show you: "Walk me through weeks 1 to 4. Who sets up the pricebook, who trains the comfort advisors, and when does the first live job happen?"

Good answer: A written plan for weeks 1 to 4 with a date for the first live job. A good vendor will also flag coaching needs early, like sellers talking too much.

11. Can we talk to a shop a couple of years ahead of us?

Yes, a vendor should connect you with a shop a couple of years ahead of you in their growth. It shows whether a tool that works for 3 trucks holds up at 40 sellers across 3 locations.

Make them answer: "Can you connect me with a shop a couple of years ahead of us?"

Good answer: A real introduction. Ask how they measured close rate before and after, what broke in the first month, and whether sellers still use it on every job.

An HVAC proposal software scoring sheet for every demo

Score each question from 1 to 5 during the demo, because afterward every tool blurs together.

• 1: The vendor couldn't show it, or showed slides instead.

• 3: They showed it live, with workarounds or on their own demo data.

• 5: They showed it on your sample home, live, and a seller could do it alone tomorrow.

Weight questions 1 through 6 double; a tool that wins the back office but loses the kitchen table won't move your close rate.

FAQ

What's the difference between HVAC estimating software and proposal software? Estimating and HVAC quoting software price the work. Proposal software turns that price into options a homeowner can browse, change, and sign.

Should my comfort advisors sit in on demos?

Yes, for at least one. Your best comfort advisor will spot in minutes whether a tool slows them down.

How many vendors should be on the shortlist?

Three is usually enough. Run all 11 questions on the same sample home with each.

Is HVAC sales software worth it if many deals close later?

Yes. If the quote stays live and sellers know when homeowners reopen it, follow-up stops living in personal text threads.
