An HVAC service agreement template, in short, covers: who the parties are, the equipment covered (make, model, serial), how many visits and what each includes, the price and billing schedule, member benefits, exclusions, the term and renewal, how to cancel and get a refund, access and safety, liability and signatures. Copy the 14-clause outline below, fill in your terms, and have a local attorney review it.

A maintenance plan sells on a sentence (“two tune-ups a year, priority service, 15% off repairs”) but it's enforced on paper. When a customer thinks the plan covers a new compressor, or wants a refund in month eleven, the agreement is what you both read. This guide gives you a residential HVAC service agreement outline with wording to adapt, the exclusions that matter, and the 2026 auto-renewal rules. It's a starting point, not legal advice: contract and consumer law vary by state. For setting the price itself, see how to price HVAC maintenance plans.

Key takeaways

List the equipment. Make, model and serial for each system covered; a plan without an equipment list covers whatever the customer remembers.
Say what a visit includes, or point to your tune-up checklist, and what it doesn't.
Discount, don't cover. Most residential plans include maintenance and a repair discount, not parts and labor on failures; say so plainly.
Auto-renewal needs care: the FTC's click-to-cancel rule was vacated in July 2025, but California's automatic renewal law (stricter since July 1, 2025) and other state laws still apply.
Make cancelling as easy as signing up, with a clear refund rule for prepaid plans.
Get it signed or accepted in writing, and keep a copy of what the customer agreed to.

What is an HVAC service agreement?

An HVAC service agreement is a contract in which you perform scheduled maintenance on a customer's equipment for a set fee, usually with member benefits like priority scheduling and repair discounts. Contractors call it a maintenance agreement, service plan, membership or club; the contract is the same. It's different from a manufacturer's warranty (which covers parts that fail) and from an extended labor warranty (which covers repair labor). Mixing those up in the wording is how disputes start.

What should an HVAC service agreement include?

Clause	What it settles
Parties and service address	Who the agreement is between and where the equipment is
Equipment covered	Which systems, by make, model and serial; how many
Scheduled visits	How many visits a year, which seasons, and how they're booked
Scope of each visit	What a tune-up includes, by reference to your checklist
Member benefits	Priority scheduling, repair discount, waived diagnostic fee, and any limits
Price and billing	Yearly, monthly or per visit; what happens if a payment fails
Term and renewal	Start date, length, and whether and how it renews
Cancellation and refunds	How to cancel, and how prepaid fees are refunded
Exclusions	What isn't included, so nobody assumes it is
Repairs found during visits	Quoted separately; nothing done without approval
Customer responsibilities	Access, pets, filters between visits, reporting problems
Liability	Limits of your responsibility, pre-existing conditions
Transfer	Whether it moves with the house or the owner
Signatures and acceptance	How the customer agreed, and the date

Replace the brackets, delete what doesn't apply, and have an attorney in your state review the result before you use it:

1. Parties. This agreement is between [Business legal name], license [number], [address, phone] (“Contractor”) and [Customer name] (“Customer”) for the property at [service address].
2. Equipment. This agreement covers the following equipment only: [system 1: type, make, model, serial]; [system 2 …]. Equipment added later is covered only if listed in writing.
3. Visits. Contractor will perform [two] maintenance visits per year: one cooling visit between [March and May] and one heating visit between [September and November]. Contractor will contact Customer to schedule each visit.
4. Scope. Each visit includes the tasks on Contractor's maintenance checklist for that season, attached as Schedule A, and a written report of findings and recommendations. [Standard 1-inch filters are included.]
5. Member benefits. While this agreement is active and paid, Customer receives: priority scheduling ahead of non-members for repair calls; [no diagnostic fee] during regular hours; and [15%] off Contractor's standard repair prices. Discounts don't apply to equipment replacement [or to work already discounted].
6. Price and billing. The fee is [$X per year, paid in advance] [or $Y per month, charged on the [date] of each month] [per system]. If a payment fails and isn't made within [14] days, benefits pause until it is.
7. Term and renewal. This agreement starts on [date] and lasts [12 months]. [It renews automatically for another 12 months at the then-current price unless either party cancels. Contractor will notify Customer of the renewal date and price [15 to 45] days before renewal.] [Or: It does not renew automatically.]
8. Cancellation and refunds. Customer may cancel at any time by [replying to any text from Contractor, using the cancel link on Customer's account page, emailing [address] or calling [number]]. Prepaid fees are refunded pro rata for the unused term, less the standard price of any visits already performed [and discounts already received].
9. Exclusions.

14. Acceptance. Customer agrees to this agreement, including the renewal and cancellation terms above, by signing below or accepting online. Date: [ ] Customer: [ ] Contractor: [ ]

What are the rules for auto-renewing service agreements in 2026?

Auto-renewal is where service agreements most often break consumer law. The federal picture changed in 2025: the FTC's “click-to-cancel” negative option rule was vacated by the Eighth Circuit on July 8, 2025, and in March 2026 the FTC started over with an advance notice of proposed rulemaking; there's no new rule yet. State laws still apply. California's automatic renewal law, as amended for contracts made or extended on or after July 1, 2025, requires, among other things:

Clear and conspicuous renewal terms before the customer signs up, and the customer's affirmative consent to them.
An acknowledgment with the terms and how to cancel.
A notice 15 to 45 days before renewal for plans with a term of a year or more, and an annual reminder for annual plans.
Notice of a price change 7 to 30 days before it takes effect.
Online cancellation, through a prominent link or button or a termination email, if the customer can sign up online.
Records of consent kept for at least three years.

Other states have their own auto-renewal rules. The simplest safe pattern: say the renewal terms next to the signature, send a reminder before every renewal, and let customers cancel by text, email or a link.

How is a commercial HVAC service agreement different?

A commercial agreement adds an asset register (every unit, its location and condition), a visit frequency per asset, response-time commitments, after-hours rates, filter and belt schedules, reporting for the facility manager, and a price-adjustment clause for multi-year terms. Survey the site before you quote; an unknown rooftop unit priced as a residential split system loses money all year.

Mistakes that cause disputes

“Covers your system” in the sales copy when the agreement covers maintenance only.
No equipment list, so a second system or a new heat pump is suddenly “included”.
Refrigerant left unmentioned. Say whether any is included.
Renewals with no reminder. A surprise annual charge is a chargeback and a bad review.
Visits that never get booked. If the customer paid for two visits and got one, refund or reschedule; don't let it lapse.

Where CrewRobin fits

CrewRobin's maintenance plans set the number of visits (1 to 12 a year) and bill yearly, monthly or per visit, on every plan. Each visit is added as a job 14 days ahead so it actually gets booked, and customers see their plan, upcoming visits and invoices on their own private page. You save a checklist per job type for the tune-up scope, and repairs found on a visit go out as a quote the customer approves and signs online. Keep the agreement wording itself in your own document. See how it works for HVAC companies.

Frequently asked questions

What is included in an HVAC service agreement?

Usually one or two scheduled maintenance visits a year, a written report, priority scheduling, and a discount on repairs. Most residential agreements don't cover repair parts, refrigerant or replacement; the agreement should list what is and isn't included.

Is an HVAC maintenance agreement a warranty?

No. A maintenance agreement pays for scheduled service and member benefits. A manufacturer's warranty covers defective parts, and an extended labor warranty covers repair labor. Keep the wording separate so customers don't confuse them.

Can an HVAC service agreement renew automatically?

Yes, but state automatic renewal laws apply. California, for example, requires clear disclosure and consent before sign-up, a reminder 15 to 45 days before an annual renewal, and easy online cancellation. The FTC's federal click-to-cancel rule was vacated in July 2025.

How do refunds work if a customer cancels a prepaid plan?

A common approach is a pro-rata refund for the unused term, less the standard price of visits already performed. Write the formula into the agreement so there's nothing to argue about.

Do I need a lawyer for an HVAC service agreement?

It's wise. A template gets you most of the way, but consumer protection, auto-renewal and liability rules vary by state, and a local attorney can check yours in an hour or two.
