HVAC Maintenance Agreements: Build the Offer, Price It from Your Costs, Automate Renewals

Why this matters

Repair spikes and install seasons leave you feast-or-famine. A maintenance agreement turns one visit into a scheduled relationship: you get predictable spring/fall work, and the customer gets priority and a clear list of what’s included. We don’t publish industry “attach rate” percentages here. Step 7 is how you measure your shop.

Step 1: Write what you will and won’t cover

Open a one-page doc before you touch pricing.

Include (be specific):

Number of visits per year (example structure: 1 heating visit, 1 cooling visit)
Equipment covered — make, model, serial, location — listed on an attachment, not “all systems at the property”
Task checklist per visit (filters if included, coil cleanliness check, drain, electrical connections, thermostat operation, safety controls). For commercial-style rigor, align your checklist with ANSI/ASHRAE/ACCA Standard 180 rather than inventing tasks from memory; obtain the standard from ASHRAE/ACCA.
Any priority scheduling promise you can actually keep
Any repair discount you can actually honor

Exclude (say it out loud):

Refrigerant, major parts, compressors, heat exchangers — unless a premium tier truly includes them
Duct alterations, mold/remediation, code upgrades, permits
Damage from storms, abuse, or DIY work
After-hours emergency labor unless that tier pays for on-call reality

If a tech can’t explain the exclusion in one sentence, rewrite it.

Step 2: Price from your visit cost, not a blog number

Do this math on a spreadsheet:

Minutes per visit (realistic, including windshield time you allocate to the job)
Burdened tech cost per hour (wage + payroll taxes + workers’ comp + benefits you actually pay)
Truck / consumables you include (filters, tablets, rags — whatever the plan pays for)
Overhead slice (office, software, insurance) allocated per visit
Margin you need after all of the above

Cost per visit = (hours × burdened rate) + consumables + overhead slice
Plan price = (cost per visit × visits per year) + value of extras (priority, discount) × your margin factor

Build three tiers so the middle offer is the one you want to sell (basic tune-ups only → standard two-visit → premium with priority + stated repair discount).

Do not copy dollar amounts from vendor blogs into your price book. Those figures are someone else’s market and cost structure. If a CSR asks “what’s normal?”, answer with your cost sheet.

Step 3: Draft the agreement sections

Your attorney finalizes wording. Your draft should already contain:

Section	What belongs there
Parties and property	Legal names, service address, your license number
Equipment schedule	Make / model / serial / location for each covered unit
Scope and checklist	Visits per year + task list
Exclusions	Parts, refrigerant, code work, etc.
Price and payment	Annual vs monthly, due dates, late fees if lawful
Term, renewal, cancel	How auto-renew works, how to opt out, refund rules
Liability / claims	Per attorney
Signatures	Customer + authorized company signer

Plain-language tip: put a one-paragraph “In short” summary above the legal text so the homeowner knows what they bought.

Step 4: Write the one-paragraph sales ask

Techs sell this at job completion and after install, when trust is highest. One script, memorized:

We put every system we install/repair on a maintenance plan so it gets a spring and fall visit on the calendar. The [Standard] plan is [price] for the year and covers [visits + checklist highlight]. It also gets you [priority / discount — only if true]. I can set the first visit before I leave so you don't have to remember. Want me to enroll this system?

Rules:

No fake scarcity (“only 3 spots left this month”) unless it’s operationally true
No invented savings percentages
If the customer says no, note it and move on — the follow-up sequence can ask once later

Step 5: Load it into your software

In Jobber, Housecall Pro, ServiceTitan, or your CRM:

Create the plan as a recurring service or membership product
Attach the checklist to the job type
Require card-on-file or invoice terms you actually enforce
Train CSR + techs on which tier to recommend by default (usually the middle)

Test: sell one plan to yourself or a friendly customer and walk the renewal date.

Step 6: Automate reminders and renewals with AI-drafted copy

Use AI to draft, then edit into your voice:

Write three short customer messages for [Company], an HVAC shop.
1) Text, 7 days before a scheduled maintenance visit. Under 300 characters. Include [First name], [Visit date window], [Tech name]. End with Reply STOP to opt out.
2) Email, 30 days before annual plan renewal. Under 120 words. Restate what's included in [Plan name]. No invented discounts. Include [Renew / manage link].
3) Text, day-of-renewal if not renewed. Polite, one ask, under 300 characters. Reply STOP to opt out.
Do not invent prices, percentages, or deadlines I didn't provide.

Automation rules:

Stop when they renew, cancel, or reply
No late-night texts
Human handles price complaints and cancellations

Step 7: Track your own attach and renewal numbers

For 90 days, log:

Tune-ups / installs completed
Plans offered
Plans sold (attach = sold ÷ offered)
Renewals when due (renewed ÷ up for renewal)

Those four numbers beat any blog benchmark. Adjust the sales ask and tier packaging based on your data.

FAQ

How much should I charge for an HVAC maintenance agreement?

Charge enough to cover your fully loaded cost per visit (tech wages, burden, truck, filters/consumables you include, overhead allocation) plus the profit margin your shop needs. Third-party blogs publish example tiers; treat those as someone else's math, not a benchmark for your market. Run your own numbers.

Is a free internet template enough?

Templates are a starting outline, not a finished contract. Payment terms, auto-renewal, cancellation, liability limits, and license disclosures are state-specific. Have a local attorney review what you actually send customers.

Should I call it a membership, agreement, or contract?

Use whatever your attorney and brand prefer. Many shops say 'maintenance plan' or 'membership' in customer-facing talk and keep the legal title clear on the signed document. Be consistent so CSRs and techs say the same thing.

Can AI write the legal agreement?

Use AI to draft plain-language explanations, checklists, and reminder emails. Do not let AI invent legal clauses you then sell. Final legal wording goes through your attorney.
