Sullivan Bookkeeping Services helps HVAC companies in Prescott Valley track what installs, service calls, and maintenance agreements actually earn — and get through the summer install rush without the books falling behind.

What HVAC Companies Get

Monthly bookkeeping and reconciliations, job costing that separates installs from service and maintenance work, payroll and 1099 filings for techs and installers, and QuickBooks Online setup built to handle the seasonal swings and HVAC businesses deal with every year.

Job Costing Built for HVAC Work

A full system install and a service call have completely different cost structures — equipment, refrigerant, and labor on an install versus a quick diagnostic fee on a service call. We set up your chart of accounts so each job type is tracked separately, so you can see whether your install margins are holding up and whether your maintenance agreements are actually profitable once you account for the labor.

Serving Prescott Valley & Yavapai County

Based in Prescott Valley, we work with HVAC companies throughout Prescott, Chino Valley, Dewey-Humboldt, and greater Yavapai County — everything remote, on QuickBooks Online.

2025-26 Clean Up Offer

Behind on 2025 books after a busy install season? Start with a focused cleanup — categorized transactions, reconciled accounts, tax-ready books, upfront pricing. Most HVAC companies sign up for monthly bookkeeping right after, so next season’s rush doesn’t bury the books again.
