How Many Maintenance Agreements Do You Need to Survive the Slow Season?
There's no universal number. It depends on your install volume, your average ticket, and how deep your seasonal dip runs. A shop that installs heavily in spring and fall and barely runs service calls in January needs a much bigger agreement base than one with steady year-round demand.
What's true for every HVAC company is this: without a maintenance agreement base, revenue swings hard with the seasons, and every slow month starts the overhead clock back at zero with less work to cover it. The agreement base is what keeps trucks rolling and techs paid when the phone isn't ringing on its own.
Why the number is different for every shop
A company doing mostly install work with a thin service department has a different problem than a company that's 80 percent service and repair. The install-heavy shop feels the slow season as idle crews and no install leads. The service-heavy shop feels it as a thinner call volume but at least has something to dispatch to.
Average ticket matters too. A shop charging $300 for a tune-up visit needs fewer agreements to hit the same revenue floor as one charging $150. And the depth of your specific seasonal dip, how many weeks run thin and how thin they run, sets the real target. A shop in a climate with a short, mild shoulder season needs less cushion than one with a hard three-month lull.
What the agreement base actually buys you
A maintenance agreement isn't really about the tune-up revenue itself, though that helps. It's about two things that matter more over time.
It gives you a reason to be on the property twice a year without waiting for something to break. That visit is where repair and replacement opportunities get found early, while the homeowner is standing right there, instead of showing up as an emergency call three years later.
It also gives dispatch something to schedule during the slow months. A tech with a route of tune-ups in February isn't an idle cost. That's the difference between carrying payroll through the slow season as a loss and carrying it as billable, if modest, work.
How to size your own target
Start with your current slow-month revenue gap: how far below your average month does your worst month fall. Then work backward from your average agreement ticket to see roughly how many active agreements would close that gap if spread across your slow weeks. Treat that as a starting target. It should move as your install volume and average ticket change.
FAQs
Should I sell maintenance agreements at the point of install or market them separately later? Point of install tends to convert better, since the homeowner is already engaged and the conversation about ongoing care fits naturally with explaining the new system. Marketing to the existing customer base separately still works, but it usually takes a dedicated push rather than happening on its own.
What if my agreement base already exists but the slow season still hurts? Check whether the agreements are actually scheduled and worked during the slow months, or whether they're sitting unscheduled until the customer calls. An agreement base only smooths revenue if dispatch is actively filling the slow weeks with those visits rather than waiting for them to be requested.
