Every March, every HVAC owner in the country runs the same campaign: “$89 Spring AC Tune-Up — Book Now Before the Heat!”
Every March, every HVAC owner gets the same 2-4% conversion rate, complains the campaign was a flop, and runs the same thing in September with “$89 Fall Furnace Tune-Up” and gets the same 2-4%.
The offer isn’t broken. The execution is.
What goes wrong in the average campaign
There are five mistakes that most shops make. Fix any one of them and your conversion bumps. Fix all five and you’re running the top-quartile campaign.
Mistake 1: One blast to the whole CRM
The owner exports the contact list, drops it into Mailchimp, and sends one email titled “Spring AC Tune-Up Special — $89 Through April 30.”
That email hits:
- Homeowners who bought a new condenser last fall (don’t need a tune-up).
- Homeowners who are commercial property managers (don’t care).
- Homeowners who bought from you 9 years ago and have probably moved.
- Homeowners on your Comfort Club already (they get tune-ups free).
- Homeowners whose system is 22 years old and is past the tune-up stage.
About 60% of your list is the wrong audience for the offer. The 40% that’s right barely sees the email because Gmail’s inbox tab placement penalizes mass-sends.
Fix: segment. The right list for spring tune-ups is:
- System install year between 2-12 years ago
- Last service over 9 months ago
- Not currently on a maintenance plan
- Residential (not commercial)
- Service area still active
That’s typically 25-40% of your CRM. Run the campaign on that segment only.
Mistake 2: Email-only
We’re past the “email is dead” point. Email still has a role, but for time-bound homeowner offers, the medium that converts is SMS.
A spring tune-up campaign that runs as a 3-touch SMS series + 1 supporting email converts 3-5× the email-only version. Open rates on the SMS will be 97%+. Click-through to the booking page typically hits 14-22%.
Mistake 3: The “$89” is the wrong offer
$89 feels like a deal until you remember:
- Your competitor on Groupon is at $59.
- Your Comfort Club membership at $24/month covers the tune-up free.
- A homeowner doing the math sees $89 every six months = $178/year, vs $288/year for the membership that also gets them 15% off any repair and no overtime fees.
So $89 either feels expensive (vs Groupon) or worse-than-membership (vs your own plan).
Fix: lead with the membership, not the tune-up. The campaign offer becomes:
“Spring is here — our Comfort Club members get their tune-up free this month. Join for $24/month and we’ll do this spring’s tune-up + this fall’s furnace tune-up + give you 15% off any repair this year. Reply YES to enroll. Or reply TUNEUP to just book the $89 tune-up.”
You give the homeowner two doors. One converts to recurring revenue, one converts to a service call. Both are wins. Real-world split tends to be 38% Comfort Club, 27% just-tune-up, 35% no-reply — vs 96% no-reply on the email-only $89 offer.
Mistake 4: Wrong timing
Most shops launch the spring campaign March 15. The right launch date is the second Saturday in February — the moment temperatures hit 55°F in the metro for the first time and homeowners start thinking about AC.
By March 15, your competitors have already booked your customers. Spring tune-up slots in the top-performing shops are 70%+ full by March 1 because they launched six weeks earlier.
Fix: trigger the workflow on a weather signal. The snapshot supports a weather API hook — when your metro hits 55°F for three consecutive days, the workflow fires. You stay ahead of the rush.
Mistake 5: No follow-up
A single SMS gets you the homeowners who were already thinking about it. Touches 2 and 3 are where the campaign earnings live.
- Touch 1 (Day 0): “Spring is here, your AC hasn’t been touched since [last service date]. Book here.” Direct calendar link.
- Touch 2 (Day 5, no response): A different angle — “Heads up, the August heat-wave waitlist filled up last year on August 4. Members skip the wait. Want me to enroll you?”
- Touch 3 (Day 12, no response): Urgency — “We have 14 tune-up slots left this month at the current rate. Want one? [Booking link]”
Touch 1 typically books 6-9% of the segment. Touches 2 and 3 add another 4-8 percentage points combined. That’s how a campaign goes from 3% to 11-15%.
The compounding piece nobody runs
Every homeowner who booked a tune-up through the spring campaign should be auto-enrolled in the fall workflow on September 15. And the homeowner who booked spring AND fall? Auto-route them to a membership pitch in October (“you’d be saving money on the membership at this point — want me to roll your fall tune-up into one?”).
This is the loop that turns a one-off campaign into a recurring-revenue engine. Without it, you’re starting from zero every March.
What the snapshot ships
- The segment query (system age, last service, plan status, service area).
- The 3-touch SMS sequence with the two-door (Comfort Club / just-tune-up) offer.
- The weather-signal trigger.
- The booking calendar with dedicated tune-up windows so dispatch isn’t fighting for slots.
- The auto-enroll-into-fall logic.
- The membership upgrade nudge on customers who hit spring + fall.
You configure once. The system runs the spring campaign in 2027 by itself.
