HVAC Businesses: your books, closed by the fifth business day.
Quick answer
For hvac businesses, TrainedBooks is automatic bookkeeping software that closes your books by the fifth business day. It sorts every bank and card transaction for you with a plain-English reason, shows your real profit and a location-aware tax set-aside (real federal + your state's rates), and prepares a tax-ready package so your tax pro just reviews and files. You review the few flagged items and own an exportable ledger. From $35/mo, with a free start, no card required, and a 30-day money-back guarantee — bookkeeping software, not a tax preparer.

HVAC installers and service companies, from one van to a small fleet. TrainedBooks closes every month by the fifth business day — equipment buys categorized as job costs, maintenance-plan income tracked, and a tax set-aside that follows your seasonal profit instead of flat-lining.
The problem
Install season buries you in equipment purchases, shoulder season goes quiet, maintenance agreements drip in monthly, and warranty callbacks cost real money that never gets counted. Cash flow whiplash makes the books feel unknowable.

Bookkeeping for hvac businesses — FAQ
Install months look rich and shoulder months look broke. Do the books help?
Yes — month-over-month trends and budget vs. actual show the seasonality honestly, and the tax set-aside recalculates on real profit each close so you reserve more in June and less in October.
Can it separate equipment for a job from equipment for my shop?
Each purchase gets a category, a confidence, and a reason — job equipment lands in cost of goods, shop tools in equipment — and anything ambiguous is flagged for a quick answer.
We take deposits before install. How does that show up?
Deposits are categorized as income when they land in the bank. TrainedBooks keeps cash-basis books — which is how most small HVAC businesses file — and your CPA gets the clean packet either way.
