HVAC maintenance agreement script: lead with two tune-ups a year and warranty protection, then ask for the yes
By Sharrk Team · October 18, 2026
A good HVAC maintenance agreement script leads with two tune-ups a year (cooling in spring, heating in fall) and protecting the manufacturer warranty, then asks a direct yes-or-no question. Sharrk can deliver that offer for you by AI call and text, follow up when a customer says "I'll think about it," and follow up on renewals so agreements don't quietly lapse.
The script below works for a technician at the end of a visit, a CSR on the phone, or an AI voice agent. Every claim in it comes from ENERGY STAR or a manufacturer's own warranty page, so your team can say it with confidence.
When should you offer an HVAC maintenance agreement?
Offer it at the moments the customer already cares about their system:
| Moment | Why it works | Who says it |
|---|---|---|
| End of a repair or tune-up visit | The customer just saw what the tech found | Technician |
| Booking call for a one-time tune-up | They already want maintenance; the plan covers both seasons | CSR or AI voice agent |
| Right after a new system install | The warranty paperwork is fresh | Installer or office follow-up |
| Late winter and late summer | Ahead of the spring cooling and fall heating check-ups | Outbound call or text to past customers |
| 30 days before an agreement expires | Renewal is easier than winning a new member | Office or automated follow-up |
ENERGY STAR recommends annual pre-season check-ups, with the cooling system checked in spring and the heating system in fall, because contractors get busy once summer and winter arrive. That timing gives you a natural, honest reason to call.
What should you say? The core HVAC maintenance agreement script
Keep it short. Three beats: what they get, why it matters, and the ask.
1. Open with what you just did or what they asked for
"Thanks for having us out today, [Name]. Your system is running, and I've noted what I checked on your ticket."
2. Offer the plan in one sentence
"Most of our customers put their system on our maintenance agreement. You get two visits a year: we check your cooling in the spring and your heating in the fall, before the busy season."
3. Give the warranty reason (use the one that matches their equipment)
"It also helps protect your manufacturer warranty. Trane, for example, says system maintenance is a requirement for its base and registered limited warranties, and it recommends maintenance twice a year."
"Lennox's basic limited warranty says failure to maintain the equipment will void it, and Lennox can ask for proof of prior maintenance. Our visits give you that record."
4. State the price and what's included
"It's [price] a month, and members also get [your perks, such as priority scheduling or a repair discount]."
5. Ask for the yes
"Want me to set that up today so your spring visit is already on the calendar?"
Then stop talking. A clear question gets a clear answer.
How do you handle "I'll think about it"?
Most hesitation is about price, timing or not seeing the value. Ask one question, answer it, and set a specific follow-up.
"Totally fair. Is it the price, or are you not sure you need two visits a year?"
If it's price:
"Understood. Think of it as the two tune-ups you'd want anyway, spread across the year, plus [member perk]. Would it help if I texted you the details so you can look them over tonight?"
If it's need:
"ENERGY STAR recommends a check-up every spring for cooling and every fall for heating. The plan just makes sure those happen on time instead of when something breaks."
If they still want to wait:
"No problem. I'll text you the plan details now and check back on [day]. If you sign up before your next visit, we'll put you on the schedule for [spring/fall]."
Write the follow-up date on the ticket or in your system before you leave. "I'll think about it" without a follow-up date is usually a no.
What does the text follow-up look like?
Send it the same day while the visit is fresh. Keep it under three short lines:
"Hi [Name], it's [Tech] from [Company]. Here are the maintenance agreement details we talked about: 2 visits a year (spring cooling, fall heating), [perks], [price]/mo. Reply YES and we'll set it up and book your next visit."
Two to three days later:
"Hi [Name], just checking in on the maintenance plan. Want me to save you a [spring/fall] slot? Reply YES or let me know any questions."
If they reply with a question, answer it. If they ask you to stop, stop.
What do HVAC maintenance agreements cost?
Price your own plan from your costs and market. For reference, here are two published plans from real companies (examples only, checked October 18, 2026):
| Example plan | Published price | Visits per year | Other inclusions listed |
|---|---|---|---|
| Champion Air "ChampionCare" | $23/month, first system | 2 (one AC, one heating) | No diagnostic fee, 15% off repairs, priority scheduling |
| CenterPoint Energy Home Service Plus Maintenance Plan | $31.95/month, one home | 2 (heating season, cooling season) | Water heater tune-up, dryer vent and bath fan cleaning |
Both plans are built around the same two seasonal visits ENERGY STAR recommends, which is why "two tune-ups a year" is the clearest way to open your offer.
How do you handle renewals?
Renewals are the easiest sale in the business, but only if someone actually asks.
- 30 days before expiry: call or text with a simple renewal ask: "Your maintenance agreement renews on [date]. Want to keep your spring and fall visits on the calendar?"
- At the last visit of the term: the tech mentions renewal in one sentence.
- After expiry: one more call and text. "We noticed your plan ended. Want us to restart it before [season]?"
Track every agreement's end date. A list of expiring members each month is the simplest renewal system there is.
How does Sharrk handle this?
Sharrk can run your maintenance agreement offer and renewals as a Strike or a Hunt:
- Strike: automatic multi-channel follow-up with timed steps by AI call, text, AI text agent, email, ringless voicemail and video text. It branches on call results and replies, and stops when the customer asks to stop, replies, or has a real conversation. It sends between 8am and 8pm by default. If you use Jobber, your Jobber clients sync into Sharrk as leads and Jobber events can start Strikes.
- Hunt: an outbound campaign to a list, such as past customers due for a spring tune-up or members whose agreements expire next month, using AI calls, a power dialer and voicemail drops. Hunts need your business to have the customers' consent to contact them, and AI outbound calls need a signed consent attestation plus approved texting registration. See our guide on whether it's legal to call leads with AI voice.
Mako, Sharrk's AI assistant, builds all of this from plain English. Tell Mako "call my past customers in March and offer our maintenance agreement, and leave a voicemail for anyone who doesn't pick up," and it builds the Hunt, shows each change on an Apply card, and lets you Undo anything.
On inbound calls, Sharrk's AI voice agent answers 24/7, uses your knowledge base (services, pricing, FAQs, hours, service areas) to explain the plan, books the visit, and live-transfers to your team when a person should take over. Every call is logged with a transcript and recording. See how this works on our AI receptionist for HVAC page and in our HVAC answering service guide.
Sharrk Core is $99 a month with every feature live, no contracts and no setup fees. You can start free and build your first offer with Mako, or book a demo.

Frequently asked questions
What is the best way to pitch an HVAC maintenance agreement?
Lead with two tune-ups a year (cooling in spring, heating in fall) and warranty protection, then ask a direct yes-or-no question. ENERGY STAR recommends those seasonal check-ups, and manufacturers such as Trane make maintenance a warranty requirement.
Does skipping maintenance void an HVAC warranty?
It can, depending on the manufacturer. Lennox's basic limited warranty says failure to maintain the equipment will void it, and Trane says system maintenance is a requirement for its base and registered limited warranties.
How often should an HVAC system get a tune-up?
Once a year per season: ENERGY STAR recommends checking cooling in spring and heating in fall. Trane recommends maintenance twice a year with a local dealer.
How much do HVAC maintenance plans cost?
Published examples run about $23 to $32 a month. Champion Air lists $23/month for the first system and CenterPoint Energy lists $31.95/month, both with two visits a year (checked October 18, 2026).
What should I say when a customer says "I'll think about it"?
Ask whether it's the price or the need, answer that one concern, and set a specific follow-up date. Text the plan details the same day and check back two to three days later.
Can Sharrk run maintenance agreement offers and renewals?
Yes. Sharrk can run the offer as a Strike (timed AI call, text and email follow-up) or as a Hunt to past customers, which needs your business to have the customers' consent to contact them.
