Free Calculators for HVAC Maintenance Plan Shops
Two working calculators for the numbers that decide whether a maintenance plan base makes money and whether your crew can actually deliver the season you sold.
Maintenance agreement pricing gets set by what the shop down the road charges, and then nobody checks the math again for five years. Meanwhile loaded labor cost went up, filters went up, drive time got longer as the service area spread out, and the plan that carried thirty percent margin quietly stopped carrying any. The first calculator here rebuilds that number from the parts you actually control.
The second calculator answers the question that shows up every March. You sold a certain number of spring visits, you have a certain number of technicians, and the window between your start date and the first ninety degree afternoon is shorter than it feels. Put your real numbers in and see how many stops the season holds before the overflow becomes a scheduling problem your customers notice.

The 90 Day HVAC Maintenance Renewal Runbook
A stage by stage checklist that takes one month of expiring agreements from a messy list to renewed members with booked tune-up appointments.
Why these tune-up calculators are open to anyone
Most residential HVAC owners already do this arithmetic on the back of a work order at nine at night. Loaded technician cost times the on-site minutes at the house, plus the windshield time between one tune-up stop and the next, plus the media filter you hand over twice a year, all set against the annual agreement price. None of it is hard math. It just gets done once every four or five years, usually right after a spring that felt busy and paid badly. So both calculators run here with no account, no email address, and no call from anyone.
They are worth something on their own even if you never look at the rest of this site. Finding out that a seventy five minute tune-up plus twenty five minutes of drive time costs more than your plan price assumes is enough to change what you charge at the next anniversary date. Finding out how many stops a crew clears in a working day tells you what week the spring booking push has to start. Write both numbers on your pricing sheet and use them with whatever you already run your agreement book on.
Turn those figures into a booked season
A delivered cost per visit and a season capacity number only matter if something acts on them. SeasonTuneUp sorts the agreement book by anniversary month, starts renewal outreach while there is still calendar left, and gets spring cooling and fall heating visits on the schedule before the first hot week takes your phone. Bring your own inputs and we will run your book through it live.
