You sell HVAC maintenance agreements by giving the plan a page that answers what a homeowner asks before paying for service when nothing is broken: when you come (cooling in spring, heating in fall), what the technician checks, what the warranty on their brand says about maintenance, what it costs, and how it renews and cancels. Write those five answers once, and every technician, invoice and email can point to them.
What does a homeowner ask before joining a plan?
A repair customer buys because something stopped working. A plan customer buys a promise about next year, so the page has to make that promise concrete. Read it the way a homeowner would, top to bottom, and check that each question has a plain answer on the page itself, not in a PDF or a phone call:
- When will you come, and will you call me or do I call you?
- What exactly happens at each visit?
- Does this protect my manufacturer’s warranty, yes or no?
- What does it cost per year or per month, and what is not included?
- Does it renew on its own, and how do I stop it?
The rest of this post is how to answer each one. The case for having the plan page at all, and how it fits beside your repair and replacement pages, is in Local SEO for HVAC companies. This is the page itself.
Schedule the visits by the season, in writing
ENERGY STAR’s maintenance checklist gives the calendar in one line: “check the cooling system in the spring and the heating system in the fall.” It suggests planning the check-ups around the spring and fall time changes. Put those two windows on the page by name, and say who makes the first move: “We call you in March for the cooling visit and in September for the heating visit.”
Then list the checks. ENERGY STAR’s list is the one to start from, because a homeowner can look it up and see that yours matches:
| Visit | Checks (from ENERGY STAR’s list) |
|---|---|
| Both visits | Thermostat settings; tighten electrical connections and measure voltage and current on motors; lubricate moving parts; check controls; check the starting cycle so the system “starts, operates, and shuts off properly” |
| Spring (cooling) | Clean evaporator and condenser coils; check the refrigerant level and adjust if necessary; clean and adjust blower components; inspect the condensate drain |
| Fall (heating) | Check gas (or oil) connections, gas pressure, burner combustion and the heat exchanger |
One line belongs to the homeowner, and the page should say so: ENERGY STAR tells owners to “inspect, clean, or change air filters once a month.” If your plan includes filters, say how many. If it does not, say that the technician will show them how, which is also ENERGY STAR’s own advice.
What the warranty actually says about maintenance
“Protects your warranty” is the line most plan pages lead with. Whether it is true depends on the brand in the customer’s yard. Three residential warranties were read for this post on October 21, 2026; other brands were not checked.
| Brand and document | What it says about maintenance |
|---|---|
| Lennox basic limited warranty (Form W900001-01, March 2025) | “Failure to maintain equipment will void this Basic Limited Warranty.” Parts are provided only if the equipment is “maintained by a licensed professional HVAC installer or licensed HVAC contractor” per Lennox’s instructions. At claim time: “Proof of prior maintenance and purchase may also be required.” |
| Trane customer care page | “System maintenance is a requirement for the Base Limited and Registered Limited Warranties.” Trane recommends “maintenance twice a year with a local dealer.” |
| Carrier condensing-unit warranty (ACHPVS-C454-02WAR, August 2026 edition) | Covers defects “under normal use and maintenance”; maintenance “must be normal and in accordance with” the installation instructions and owner’s manual. No sentence asks for proof. The ten-year term depends on registration “within ninety (90) days of original installation.” |
So for Lennox equipment, a plan visit done by a licensed contractor and written down is part of keeping the warranty, and it is the proof Lennox says it may ask for. For Trane, the page says maintenance is a requirement of both warranties and names no contractor or proof rule. For Carrier, the honest claim is narrower: maintenance done to the manual, with a record you can produce if the question comes up.
Lennox gives the owner 45 days. Its warranty says “All warranty claims must be submitted within forty-five (45) days of the applicable product failure date.” A plan member whose compressor fails will want the visit records that day. Keep each visit’s date, the technician, the model and serial number, and what was checked, and say on the page that you keep them.
Write the warranty line brand by brand
Turn the table into sentences the page can carry without promising more than the documents do.
| Instead of | Write |
|---|---|
| “Keeps your manufacturer warranty valid.” | “Lennox and Trane require regular maintenance for their warranties. Our plan visits are done by licensed technicians and recorded, so you have the proof Lennox says it may ask for.” |
| “Required by all manufacturers.” | “Carrier asks that maintenance follow its manuals. Our visit checklist follows them, and we keep the record.” |
| “Warranty-approved maintenance.” | Name the brands you service, link each one’s warranty document, and say which you have read. |
Two more lines belong near the warranty paragraph, because the documents say them and customers do not expect them. Lennox leaves the owner “all trip charges, labor costs, and other costs involved in diagnostic calls.” Carrier excludes labor and “Any cost to replace, refill or dispose of refrigerant.” A warranty covers the part; the plan is where you say what you do about the rest.
Carrier’s own warranty also says the longer term needs registration within 90 days. If you register the equipment for the customer at install, say so on the plan page as one of the things you already did.
Put your price on the page, with the edges
The price is yours, and no figure in this post should be read as a suggestion. What the page owes the reader is the shape of it:
- The annual price, and the monthly figure if you bill monthly.
- What each visit includes, linked to the checklist above.
- What the plan discounts on a repair, if anything, as a percentage or a flat figure.
- What it does not include: parts, refrigerant, after-hours calls, or whatever your plan leaves out. Both warranties read here put filters and lubricants on the owner’s side, so say whether yours does.
- Whether one plan covers one system or the whole house.
A table with one column per tier is easier to read than three paragraphs. Keep it to two or three tiers; each extra one is another thing the technician has to explain at the door.
Write the renewal line next to the price, not under the button. The California statute below asks for the terms “in visual proximity” to the request for consent, and a customer comparing two companies reads the price and the renewal together anyway.
Renewal and cancellation: what goes before the button
Reviewed on October 21, 2026: California’s Automatic Renewal Law and the federal Restore Online Shoppers’ Confidence Act. Other states were not checked.
California, Business and Professions Code §17602. It covers a plan that “is automatically renewed at the end of a definite term for a subsequent term.” Before the customer agrees, the page shows, clearly and conspicuously and “in visual proximity” to the request for consent, that the plan continues until they cancel, the cancellation policy and the recurring charge. “Clear and conspicuous” means larger type, a contrasting type, font or color, or set off by symbols. After sign-up, the business sends an acknowledgment that the customer can keep, with the terms and how to cancel. For a term of a year or longer, a notice goes out “at least 15 days and not more than 45 days before” renewal, and an annual reminder states the charges and the means to cancel. A plan bought online must be cancellable “exclusively online, at will.” Proof of consent is kept for at least three years, or one year after the contract ends, whichever is longer. The 2024 amendments apply to contracts entered into, amended or extended from July 1, 2025.
The article exempts service contract sellers and administrators regulated by the Bureau of Electronic and Appliance Repair under Business and Professions Code section 9855 and following. Whether your plan is one of those was not checked; ask a California lawyer before relying on it.
Federal, 15 U.S.C. §8403. For anything sold online with a negative option feature, the seller “clearly and conspicuously discloses all material terms of the transaction before obtaining the consumer’s billing information,” gets “express informed consent” before charging, and “provides simple mechanisms” to stop recurring charges. The FTC’s broader 2024 negative option rule was vacated by the Eighth Circuit on July 8, 2025; the statute was not part of that case.
The page wording that follows from both, for a plan sold online:
- “This plan renews every 12 months at [price] until you cancel.”
- “We’ll email you between 15 and 45 days before it renews.”
- “Cancel any time at [link], or call [number].”
Selling it from the rest of the site
The plan page does the explaining, so the selling can happen anywhere a customer already is. Link to it from the bottom of every repair page and every replacement quote, with one sentence about the next visit’s season. Put the link in the invoice email after a repair. When a technician finishes a spring visit, the record they write is the proof a Lennox owner may be asked for, and the maintenance a Trane owner’s warranty requires; telling them so at the door is a better close than a discount.
Plan members are also the customers to ask for a review after a visit, because they have seen you twice. How to ask without breaking Google’s rules is in how to ask for Google reviews. If you offer separate plans for commercial and residential customers, give each its own page; how many service pages explains when a job earns its own.
LocalBiz does not take payments, run subscriptions or send renewal notices. Billing, the renewal email and the cancel link stay with your payment or field-service software. What LocalBiz does is build the website and draft the plan page with the sections above, the visit checklist, the warranty lines for the brands you name and a place for your price and renewal terms, then link it from your repair and replacement pages. The price, the brands and the terms come from you.
Count the first year by page: sign-ups that came from the plan page, from a repair page and from the invoice email, then renewals twelve months later. If your plan page is ready to write, a site that builds it with the rest of your pages is where to start.
Frequently asked questions
Does an HVAC maintenance plan keep a manufacturer's warranty valid?
It depends on the brand, so say which. Lennox’s basic warranty says failure to maintain equipment will void it and that proof of prior maintenance may be required. Trane says system maintenance is a requirement for its base and registered warranties. Carrier’s condensing-unit warranty asks for maintenance per its manuals but names no proof. Quote the brands you install, not the industry.
When should the two maintenance visits be scheduled?
ENERGY STAR says to check the cooling system in the spring and the heating system in the fall, and suggests planning the check-ups around the spring and fall time changes. A plan page that names those two windows tells the customer when you will call, and gives your office a calendar to book against before the first heat wave and the first cold night.
Do I have to send a reminder before an annual HVAC plan renews?
In California, for a plan with a term of one year or longer that renews unless the customer cancels, Business and Professions Code section 17602 requires a notice 15 to 45 days before it renews, plus an annual reminder with the charges and how to cancel. Other states were not checked for this post, and one exemption may apply, so ask a lawyer where you operate.
Should the plan page show a price?
Yes, and the figure is yours to set. Show the annual price, the monthly figure if you bill monthly, what each visit includes and what it does not. The Lennox and Carrier warranties leave labor, filters and refrigerant costs to the owner, so say plainly which of those the plan discounts and which it does not.
