The Spring Tune-Up Campaign: How HVAC Contractors Can Fill April and May With One Automated SMS Sequence
A done-for-you playbook for turning your customer list into 30-50 booked AC tune-ups before the first heat wave.

Every HVAC contractor in Ontario knows the same brutal truth about spring: there is a six-week window between mid-April and the end of May when AC tune-up demand peaks, and whichever company fills its calendar first wins the entire season. The contractors who go into that window with a half-empty April calendar end up burning marketing dollars on Google Ads to scramble for last-minute jobs. The contractors who prepare a proper customer-base campaign in March walk into April fully booked, with a queue building into June. The difference between the two outcomes is rarely the quality of the work — it is whether the owner has an automated outreach system or is still doing it by hand.
Here is the exact spring tune-up SMS sequence we run for HVAC contractors in Hamilton, Burlington, Oakville, and the broader GTA. We call it the "3-Touch Spring Trigger" and it consistently books 30-50 tune-ups for a contractor with 800-1,500 past customers in their database. The whole thing runs on autopilot once it is configured, and the only manual work the owner does is confirming the bookings as they land on the calendar.
**Touch 1 — The Soft Reminder (third week of March).** This is the warm-up message and it goes to every past customer who has had any service in the last 36 months. The copy is intentionally low-pressure: "Hi [First Name], it is [Owner Name] from [Company]. Just a quick heads-up that AC tune-up season is starting and our calendar fills up fast in April. Want me to lock in a spot now? Just reply YES and I will send you a few times." That is it. No discount, no pricing, no fluff. About 8-12% of recipients reply within 48 hours, which for a 1,000-contact list is 80-120 instant conversations.
**Touch 2 — The Specific Offer (first week of April).** This goes only to non-responders from Touch 1, and it switches to a concrete incentive: "Hi [First Name], spring AC tune-up special at [Company] this month — $129 (normally $179), includes full system check, coil clean, refrigerant top-up, and a written report. We have a few spots left on [Day] and [Day]. Reply BOOK and I will send the link." The price anchor and time scarcity push a different segment of customers off the fence — typically another 5-8% reply, which on the same 1,000-contact list is another 50-80 conversations.
**Touch 3 — The Last Call (third week of April).** This is short, urgent, and goes only to remaining non-responders: "Hi [First Name], last chance for spring AC tune-up pricing at [Company] before May. Calendar is 80% full. Reply YES if you want one of the remaining spots." This typically converts another 2-4%, which adds 20-40 more conversations. Across all three touches you have generated 150-240 real conversations from a single 1,000-contact list, of which 40-60% become booked tune-ups. That is 60-140 booked jobs from one campaign that took 20 minutes to configure.
The automation handles the parts that would normally crush an owner doing this by hand. When a customer replies YES, an AI workflow takes over the conversation: it confirms their address, checks your real-time calendar, offers two or three open slots, books the appointment, sends a confirmation, and schedules a reminder SMS 24 hours before the visit. The owner never touches it unless the customer asks a complex question ("my system is 15 years old, should I just replace it?") in which case the AI tags the owner with full context. The owner spends their time doing actual tune-ups, not playing scheduling tag.
There are a few critical details that separate campaigns that print money from campaigns that flop. **Sender identity matters.** The SMS has to come from a number the customer recognizes — ideally the same business line they have texted before, or a clearly labeled 10-digit local number. Generic short codes get ignored. **Owner first name matters.** "It is Mike from Northern Comfort" converts 2-3x better than "This is Northern Comfort." Customers reply to people, not businesses. **Timing matters.** Send between 10 AM and 2 PM on weekdays — never evenings, never weekends. Homeowners are at work, see the message, and respond from their desk.
**Compliance is non-negotiable.** Every message must comply with CASL since you are using existing business relationships. That means clear business identification in the first line, an unsubscribe option ("Reply STOP to opt out") in the footer, and you cannot include the campaign anyone who has previously unsubscribed. We also recommend pacing the send — don't blast all 1,000 contacts in one minute. A 30-60 minute drip-send keeps your messaging volume below carrier spam thresholds and keeps deliverability above 95%.
The economics on this campaign are absurd in the best way. A spring tune-up runs an average of $129-179 in the GTA, and the average tune-up customer generates another $400-600 of upsell within 12 months (filter replacements, duct cleaning, the eventual furnace or AC replacement). So 80 booked tune-ups from a single April campaign is roughly $11,000 in immediate revenue and another $35,000-50,000 in downstream lifetime value. The total cost of the campaign is the SMS sending fees (about $40-80 for 1,000 contacts across three touches) plus the AutomateLocal subscription. ROI typically lands between 80x and 150x on the campaign itself, and the workflow is reusable for fall furnace tune-ups in October.
This campaign works best when it is layered onto your existing automation stack. If you are also running [missed call text back](/blog/missed-call-text-back-ontario-contractors) you will catch every spring inbound call that goes to voicemail. If you have [database reactivation](/blog/database-reactivation-strategies-contractors) running quarterly you have already warmed up the list. And if you have an [AI receptionist](/blog/ai-receptionist-small-business-guide) handling the booked-appointment confirmations, the entire season runs without the owner ever touching the office phone.
If you are an HVAC contractor in Hamilton, Burlington, Oakville, Niagara, or anywhere in the GTA and your spring calendar still has gaps, this campaign is the fastest way to fill it before competitors flood the market with Google Ads. [Book a 15-minute demo](/contact) before the end of March and we will load your customer list, write the three-touch sequence in your brand voice, and have it ready to launch the week of your choice. Most contractors see their first booked tune-up within two hours of the first send going live.
