Your market
doesn't care
who your agency is.

HVAC maintenance agreements run $150 to $500 per year nationally, with most healthy operations pricing between $200 and $350. The agreement itself is rarely a profit center — the return shows up in the repair pipeline, replacement conversion, and customer retention from the maintenance customer base. Here is the tier structure that holds up, the modeled per-agreement margin math, and how to price the program for your market.

Industry-typical HVAC callback rates run 1-2% at top shops, 3-5% at acceptable shops, and 8%+ at broken-process shops. The harder problem is definition — the same operation can look like a 1.5% callback rate or an 8% callback rate depending on what you count. Here is the breakdown of every callback type, the modeled cost per callback, and how top operations actually track and reduce them.

Housecall Pro publishes pricing. ServiceTitan and FieldEdge do not. The first costs $59-$149 per month for small teams. The second runs an estimated $125-$398 per user per month plus $5K-$25K to implement. Here is the honest TCO at 3, 8, and 20 technicians, what each platform actually does, and the hidden costs nobody mentions in the sales pitch.
