HVAC runs hot and cold with the seasons, mixes parts and labor on every ticket, and often carries maintenance agreements that need tracking. We keep your books clean through all of it, so your cash flow and profit stay clear year round.
Clean books are the difference between running your hvac business on real numbers and running it on guesswork. We give you accurate, up to date bookkeeping and clear reporting, so every decision, from pricing to hiring to your next investment, rests on what is really happening in your business, not a rough estimate at year end.
Why it is different
An HVAC company can be slammed in summer and quiet in winter, so cash flow needs careful tracking to survive the slow months. On top of that, every job blends parts and labor, and maintenance agreements bring revenue that has to be recognized over time.
We separate parts and labor, track your parts inventory, handle service agreement revenue, and keep technician payroll clean, so your profit by job and your seasonal cash position are always clear.

Cash flow tracked and planned around your busy and slow seasons.
Maintenance agreement revenue tracked and recognized correctly.

HVAC accounting guide
An HVAC company runs two businesses at once: install jobs with big material costs, and service and maintenance work with small tickets, trucks full of parts and recurring agreements. Your books need to show the margin on each, or the busy season hides the jobs that lose money.
Track revenue and direct costs separately for new installs, replacements, repairs and maintenance. Installs often look large on the P&L but carry equipment costs that squeeze the margin. Service calls are usually more profitable per hour. Job costing each install, and tagging service tickets by type, shows where the money is really made. Check any job with the free profit margin calculator.
When a customer prepays for a one-year maintenance plan, you have not earned it all on day one. Under accrual accounting the payment goes to deferred revenue and is recognized as the visits are performed or over the plan term. Booking it all as income upfront overstates profit in the month you sell plans and understates it later.
Parts on trucks and in the shop are inventory until they are used on a job. Recording every parts purchase straight to expense makes job costs and margins unreliable. A simple periodic count by truck, or inventory tracking in your field software, keeps cost of goods sold accurate.
Commissions and spiffs paid to technicians belong in job or direct labor costs, not overhead. Warranty and callback work costs real labor and parts even when you can’t bill it, so track it separately to see its true cost.
States treat HVAC differently. In some, an installation is a real property improvement and the contractor pays sales or use tax on materials. In others, the parts on a repair invoice are taxable to the customer. Getting this wrong across many small invoices adds up, so we set it up by state from the start. See our sales tax guide.
Field service software such as ServiceTitan, Housecall Pro or Jobber syncs to QuickBooks Online. We clean up that sync so invoices, payments and fees match the bank. See QuickBooks bookkeeping.

It depends on the state and the type of work. Some states treat installations as real property improvements, where the contractor pays tax on materials. Others tax parts billed on repairs. Check your state rules or ask your bookkeeper to set it up correctly.
