How to use this template

The template above is a complete residential maintenance agreement — two tune-up visits a year, membership perks, pricing, renewal, and cancellation terms. To make it yours:

One structural note: most solo shops should start with one plan. If you want tiers later, the standard pattern is a base plan (this template as-is) plus a premium tier that upgrades Section 4 — a bigger repair discount, all diagnostic fees waived, no overtime surcharge ever — and Section 3, with extras like a filter program or minor parts included up to a dollar cap. Edit those two sections to build the premium version rather than maintaining separate documents.

Why maintenance agreements matter for a solo HVAC business

A maintenance agreement is the only product a one-truck HVAC shop can sell that produces revenue while the phone isn't ringing. Everything else you sell requires a breakdown, a callback, or a referral to happen first. The agreement is money booked in advance.

The math is simple, and it compounds. Say you charge $199 a year: 50 agreements is $9,950 a year booked before a single service call comes in — roughly $829 a month you can count on. At 150 agreements it's about $29,850 a year. That's the difference between a dead January and a scheduled January.

The revenue is only part of it:

How to price your agreement

All the numbers here are illustrative — plug in your own costs and rates. Start from what the agreement costs you to deliver: two visits at roughly 1.5 hours on-site each, plus drive time, is about 4 hours a year. At an illustrative fully-loaded target of $120 an hour, that's roughly $480 of your time delivered at retail value.

That's why agreements are priced at a discount to two à-la-carte tune-ups but above your true cost. Say your standalone tune-up is $149: two of them à la carte is $298, so the agreement typically lands around $199 to $279 a year. The gap between the agreement price and the à-la-carte price is justified by the membership benefits — priority service and the repair discount — not by cutting your margin.

Three rules of thumb:

How to sell it on service calls

The close happens at the end of a repair call, at the moment of maximum trust — the system is running again, and you're the person who fixed it. The pitch writes itself: "Today's diagnostic fee was $89 — on the maintenance plan that's waived, and this repair would have been 10% off. It's $199 a year and I come out twice to keep this from happening again."

Three tactics that cost nothing:

The template gets you the signature. The work starts after.

Every agreement you sell is two visits you have to remember to schedule, every year, forever — plus a renewal date, a billing schedule, and a customer who now expects you to call them. At ten agreements, that's a spreadsheet. At fifty, it's the exact evening paperwork the agreement business was supposed to prevent — and one forgotten spring visit is how an agreement customer becomes an ex-customer.

We're building Deskhand — so read this section knowing that — service call software for one- and two-person licensed trade shops, at $49 a month flat. Its recurring jobs feature exists for exactly this document: sell an agreement, and the spring and fall visits schedule themselves onto your calendar every year, with reminder texts to the customer, invoices generated on schedule, and everything synced two-way to QuickBooks.

The honest part: Deskhand hasn't launched yet. The template above is yours regardless — no email, no strings. If the software described here is what you've been looking for, join the early access list — founding members lock in $49 a month for life.

FAQ

Common questions

What should an HVAC service agreement include?

A complete residential maintenance agreement covers ten things: the parties and the property address; a specific covered-equipment list with model and serial numbers; exactly what each visit includes, ideally as itemized spring and fall checklists; the price and billing schedule; the membership perks, such as priority scheduling and repair discounts; clear exclusions stating that it is a maintenance plan — not a warranty or repair plan; the term and how renewal works; cancellation and refund terms; a limitation of liability; and signatures. The template on this page includes all of these. Whatever you start from, have a local attorney review it — several states regulate service contracts and automatic renewal terms specifically.

How much should I charge for an HVAC maintenance agreement?

There is no universal number, but the common approach is to price below the cost of two à-la-carte tune-ups and above your cost to deliver both visits. As an illustration: if your standalone tune-up is $149, two of them would be $298 à la carte, so the agreement typically lands somewhere around $199 to $279 per year for one system, with additional systems priced per system. The gap is justified by the membership benefits — priority scheduling and the repair discount. A monthly payment option, roughly $17 to $23 a month in that example, usually converts better than the annual figure, even though it is the same money.

Are HVAC maintenance agreements profitable?

The visits themselves are modestly profitable at best — and that is by design. The profit comes from everything that surrounds them: guaranteed base revenue that fills the spring and fall slow seasons, repair work discovered during the inspections, replacement jobs when a covered system reaches end of life with you standing there as the incumbent, and retention, because agreement customers do not call around for quotes when something breaks. A book of agreements also makes the business more predictable month to month, and more valuable if you ever sell it, since contracted recurring revenue is what buyers actually pay for.

How do I get customers to sign up for a maintenance plan?

The highest-converting moment is the end of a repair call, when trust is at its peak. Make the offer concrete: waive or credit today's diagnostic fee toward the first year, show what the repair discount would have saved on today's invoice, and explain the priority line — plan customers get scheduled first during heat waves and cold snaps. Beyond that moment, put the plan on every invoice and estimate as a line item, and mention it during every à-la-carte tune-up you perform. You do not need marketing spend to build a book of agreements — you need to make the offer every single time you are already in the house.

Is this template legally binding? Do I need a lawyer?

A signed agreement can form a binding contract, but this template is provided for informational purposes only and is not legal advice — and no template from the internet should go in front of customers unreviewed. State laws differ meaningfully on service contracts, automatic renewal disclosure requirements, cancellation rights, and consumer protection rules, and a clause that is fine in one state can be unenforceable or even a violation in another. Have a licensed attorney in your state review the document once; a one-time flat-fee review is a small cost that covers every agreement you sign afterward.
