Estimating automation for HVAC: follow-up and unsold-estimate recovery on your platform
Your comfort advisor writes a good proposal and then the week happens. Financing never gets re-offered, the good-better-best never gets re-sent, and the unsold estimate sits in a status nobody filters by. We automate the follow-up off your estimate status, put the callback on your advisor's desk each morning, and build custom sales tools only where your platform genuinely can't do what you want.
What changes for your sales desk
3 things that decide this
- 01Every estimate gets followed up on a schedule your advisor would follow if they had the time: a text, a financing reminder, a 'what changed' nudge, and a callback list at 8am.
- 02Financing gets offered twice, not once. The second offer is where a lot of replacements close, and it's the one nobody remembers to make.
- 03Your advisor still makes the call. We make sure the right call is on their desk with the context attached, and that the unsold backlog is a number you can see.
From proposal to sold, and what each step writes back
This is the station of the HVAC chain that estimating automation owns, with the two on either side of it for context. Pick your platform.
Station 01 · The estimate goes out
- Today
- Your advisor builds the proposal in the platform or a pricebook tool, sends it, and logs it. From here the follow-up depends on memory and a free afternoon.
- What we automate
- Your estimate status becomes the trigger. A text confirms receipt and offers a time to talk; a financing option goes with it, not after it.
- What stays human
- Writing the proposal itself stays human. Good-better-best is a judgement about the home and the homeowner, and it stays your advisor's.

Station 02 · The follow-up sequence
- Today
- If the homeowner goes quiet, the estimate goes quiet too. Nobody re-offers financing, and seasonality decides whether it ever closes.
- What we automate
- Timed touches off the status: a reminder, a financing reminder with the monthly figure, a 'what changed' nudge when the weather turns, and a callback list on the advisor's desk each morning with the history attached.
- What stays human
- Your advisor still makes the call, ringing the ones the sequence surfaces, with the context in front of them, instead of scrolling a list.

Station 03 · Sold, or closed-lost, on purpose
- Today
- Estimates stay open forever, so the backlog number means nothing and nobody knows what the recovery rate is.
- What we automate
- An estimate that gets no response after the sequence is closed-lost with a reason, so the backlog is real and the recovery rate is a number you can watch month to month.
- What stays human
- Your sales manager decides the rules, how many touches, how long, what counts as lost, and the system only runs what they decided.

Four things that recover estimates your desk doesn't have time for
Follow-up off the estimate status
A text, a financing reminder, a 'what changed' nudge and a callback list, all triggered by the status already in your platform. There's nothing for anyone to remember.
Financing, offered twice
That second offer is where replacements close, and it's the one nobody remembers to make. We make it automatically, with the monthly figure, at the moment the homeowner is weighing it.
The advisor's morning list
Eight estimates, the history on each, the reason the sequence flagged it. Your advisor calls the right ones instead of scrolling the whole pipeline.
Custom sales tools, only where needed
Most shops need automation around the estimating they already do. A few need a tool the platform can't offer: a financing comparison the homeowner can play with, a replacement-vs-repair calculator. We build those only when the audit shows you need them.
Your platform's estimating is fine. The follow-up is what's missing.
ServiceTitan, Housecall Pro, Jobber and the pricebook tools around them are good at building and sending a proposal. They're much thinner on what happens after: the reminder cadence, the financing re-offer, the seasonal nudge, the closed-lost discipline that makes your backlog number mean something. Most shops fill that gap with an advisor's memory and a quiet Friday.
That gap is what we automate, and it's the easiest win in the whole HVAC chain because the proposal already exists. Where a shop genuinely needs a sales tool the platform can't offer, we build that too, but we'll tell you on the audit if you don't.
- 01Triggered by the status already in your platform; nothing new to key in.
- 02Your rules for touches, timing and what counts as lost.
- 03Your advisor keeps the call; the system keeps the calendar.
“They will treat your vision like their own and build it that way.”

Some of the systems we have shipped
- AuditFree. We read your estimate backlog: how many are open, how old, and how many ever got a second touch.
- DiagnoseWe map the path into your board and sit with your desk for an afternoon.
- BuildFixed price from the diagnostic. Tested on your real numbers and real jobs.
- RunMonitoring, a named engineer, and the first two months of maintenance free.
Best fit: five or more trucks, a CSR desk, and a platform you've outgrown in places. Not a fit: a one-truck owner-operator. You can stop after any stage; the audit report is yours either way.
Before you book
01Does this work with the estimates we already build in ServiceTitan, Housecall Pro, Jobber or our own pricebook?+
Yes, because it runs off the estimate status your platform already records. Your sequence triggers when an estimate is sent, pauses when it's sold, and closes it when your rules say it's lost. We confirm what your account exposes during the audit, before anyone estimates the build.
02Will it spam our homeowners?+
No. You set the touches and the spacing, and the sequence stops the moment the homeowner replies or books. A sensible cadence is three or four touches across two to three weeks, with a seasonal nudge later. It's the cadence your best advisor would follow if they had the time.
03Can it re-offer financing?+
That's exactly what it's for. A second financing offer, with the monthly figure, goes out at the moment the homeowner is weighing the decision, and it's the offer nobody on the desk remembers to make. Where your financing provider has an API we connect it; where they don't, the offer carries your current terms as a link.
04What does the advisor actually see?+
A short list each morning: the estimates the sequence has surfaced, the history on each, the reason it's on the list. They call those, and only those. Everything else in the pipeline carries on in the background without them scrolling through it.
05How do we measure whether it worked?+
Two numbers you probably can't see today: the unsold backlog, now real because lost estimates get closed with a reason, and the recovery rate on estimates older than two weeks. We don't quote you an expected percentage; we baseline your own shop on the audit and watch it move.
06Is this the whole of what you do for HVAC companies?+
No, this page is only the sales layer. The phone, dispatch and the field, and the money and membership side are their own layers. Our hub page walks the whole chain; this one is estimates.

Your audit call is with an engineer who has read call logs and job boards like yours. Bring last month's numbers if you have them, and we'll work from those.
- NDA before the first conversation.
- No pitch on the call. A report you could hand to another firm.
- Fixed price after the diagnostic, so the number isn't a guess.
