Free HVAC flat rate pricing software: what free actually covers
If you searched for free flat rate pricing software for an HVAC shop, you probably saw subscriptions starting around $129+/month and wanted to know whether you can skip them. Sometimes you can. This page sorts out which free options do real work and where free ends up costing more.
Prices below are published list prices as of July 2026. For the paid vendors side by side, see the flat rate software comparison.
What a flat rate book actually needs
Strip away the tablet app and a flat rate book is a list of tasks, each with a cost, the hours it takes, a labor rate, a material markup and a sell price. The math is one formula. Most of the subscription price pays for the task library and the screen a tech shows the homeowner, not for anything a calculator can’t do.
The free options, and what each one does
A spreadsheet. Fully flexible and free. Fine for ten to fifty tasks. It gets painful when prices change, because every edit has to be re-keyed into the platform your techs use.
A starter price book. The free HVAC price book template gives you structured tasks with prices already attached, in a CSV that imports into Housecall Pro. It’s a starting point, so you still adjust it to your labor rate.
Free calculators. The flat rate price calculator runs the per-job math, and the other free tools on the tools page cover hourly rate and parts markup.
Your platform’s own price book. Housecall Pro and similar platforms include a place to store priced tasks. They give you the structure, not the prices.
Some paid vendors may offer trials or free tiers. We haven’t verified any, so check each vendor’s own site rather than trusting a number here.
Where free stops saving you money
The expensive failure isn’t a missing feature. It’s a book full of prices nobody has checked against current costs. Software, free or paid, only stores whatever you or a vendor put in. A shop with an old book and a free calculator still sells jobs below target margin, just with a nicer spreadsheet.

Repricing the book you already have
Check the number before you budget. The New Flat Rate’s pricing page has changed since our July 2026check and we haven’t been able to confirm the new figure, so that price may be out of date. Ask for a written quote before you compare.
A practical order to try things
Load the free starter book, run your numbers through the calculator, and check your current book with the free Margin Leak Finder. If the leaks are small, you’re done and you spent nothing. If they aren’t, the Margin-Right Rebuild reprices every task for $249 one time. Optional continuity software is $299/yr ($199/yr founding). If you’re weighing paid pricing software too, the HVAC price book software comparison covers first-year costs.
The 60-Day Ticket-Lift Guarantee
If your average ticket doesn't go up within 60 days of importing your new price book, we refund the full price — and you keep every file.
Frequently asked questions
Is there free HVAC flat rate pricing software?
There is no free full flat-rate suite, but the working pieces are free: a priced HVAC starter price book, a flat rate calculator for the per-job math, and a margin checker that reads your existing book. For a one- to three-truck shop, those plus the price book inside your field service platform cover most of what the subscriptions sell.
Can I do flat rate pricing in a spreadsheet?
Yes. A spreadsheet with cost, hours, labor rate, markup and sell price per task is a working flat rate book. It stops being cheap when it has to be re-keyed into your field service platform after every price change, or when two people edit different copies.
What do the paid flat rate vendors charge?
Published list prices as of July 2026: Profit Rhino $179+/month, Coolfront $129+/month, and The New Flat Rate $99/tech/month. Final quotes are usually set on a sales call. The New Flat Rate's pricing page has changed since our July 2026 check and we haven't confirmed the new figure, so treat that price as possibly out of date.
Does Housecall Pro include a free flat rate price book?
Housecall Pro includes a price book you can fill yourself, but it gives you the structure, not priced HVAC tasks. You still have to load tasks and set every price against your labor rate and material costs.
When is free flat rate pricing software not enough?
Free stops being enough when the prices inside the book are wrong, because no tool fixes a price nobody checked. If your book was priced years ago, a one-time rebuild at $249 reprices every task to your target margin and you keep the files.
What should free HVAC pricing software include?
At minimum it should hold cost, labor hours, markup and sell price for each task, calculate the margin, and export to a file your field service platform can import. If it can't export, the prices live in the tool instead of your business.
Check your book before you pay for any software
Run your price book export through the free Margin Leak Finder. It works entirely in your browser and shows which tasks sit below your target margin. If the leaks are real, the Margin-Right Rebuild fixes the whole book for $249, one time, backed by the 60-Day Ticket-Lift Guarantee. We open 10 rebuild slots a month.
