The short answer:
- The agreements plan is the price that matters. Housecall Pro puts maintenance agreements on Max ($329 a month), Tradify on Plus, GorillaDesk on Pro, ServiceM8 on Growing, and Service Fusion on Pro or as a $149 a month add-on to Plus. ServiceTitan keeps memberships in The Works.
- Our pick for a 5-tech HVAC shop: ServiceM8 Growing, about $8,568 a year with card fees. ServiceM8 charges by jobs a month with unlimited users, so a fifth technician costs nothing extra.
- Card fees are the bigger number. At 50 invoices of $400 a month, Housecall Pro’s 2.99% online rate comes to $598 a month, more than its Max plan.
- 4 apps that run agreements publish no price: ServiceTitan, Workiz, FieldEdge, Simpro. You only find out the cost on a sales call.

ServiceTitan, FieldEdge and Workiz
These three sell through a demo, with no published price. ServiceTitan prices per technician and keeps memberships in The Works; Workiz keeps agreements on Ultimate; FieldEdge lists basic agreements on Select and advanced ones on Premier. See what ServiceTitan charges and what to ask on the call, and FieldPulse’s contract terms if it’s on your list.

Common questions
What is the best software for HVAC?
For a small HVAC shop, the best fit is the cheapest plan that runs maintenance agreements. At our 5-tech example, that is ServiceM8's Growing plan, because it charges by jobs a month, not by technician. ServiceTitan, FieldEdge and Workiz also run agreements but publish no prices, so you can only compare them after a sales call.
How much does HVAC software cost?
With maintenance agreements included, published plans start at $79 a month (ServiceM8 Growing, unlimited users). Housecall Pro needs its Max plan, $329 a month for up to 8 users. Card fees on your invoices usually cost more than the software. ServiceTitan, FieldEdge and Workiz quote a price after a demo.
Is there any free HVAC software?
ServiceM8 has a free plan for 1 user and 30 jobs a month, but maintenance agreements start on its Growing plan. Most other apps offer a free trial instead: Jobber and Housecall Pro for 14 days, with no credit card.
Does Jobber have maintenance agreements?
Jobber's pricing page doesn't say which plan includes service or maintenance agreements; we checked its plan table again on October 26, 2026. If agreements matter, ask Jobber which plan has them before you buy.
