2027 Summer AC Tune-Up Campaign for HVAC: The Sequence That Fills the Schedule

July is not when you sell tune-ups. July is when you do the tune-ups you sold in April — plus the emergency no-cool calls that pay double and wreck your schedule. The campaign below runs March through May and does three jobs: fills the shoulder-season schedule with planned maintenance, converts one-time tune-ups into maintenance agreements, and builds the list you'll reactivate when the first heat wave hits.

The timeline: March, April, May

• March — prep month. Segment the list (below), write the messages, block the tune-up capacity on the dispatch board, stock filters and capacitors. Nothing sends yet.
• April — the campaign. The full sequence fires. Goal: book 60–70% of your summer tune-up capacity before May 1.
• May — the cleanup. Re-message non-responders once, then shift the board to heat-wave readiness. The campaign is over; the schedule is set.

Step 1: Segment the list (March)

One blast to everyone is lazy and it underperforms. Four segments:

• Maintenance agreement members. They're already sold — this is a scheduling message, not a sales message. "Your spring tune-up is due; pick your slot."
• Past customers, no agreement. The core campaign audience. They know you, they trust you, they haven't committed.
• Systems 8+ years old. Pull from install records. These get the "your system is entering the expensive years" angle plus the replacement-seeding message.
• Dead estimates (replacement quotes that didn't close). A tune-up is a low-commitment reason to get back in the door — and in front of that aging system again.

Step 2: The April sequence (copy-paste ready)

Three touches, 10 days apart, text-first. Write them in March, schedule them in April.

Touch 1 — the early-bird (April 1)

Touch 2 — the agreement upgrade (April 11, to non-responders + tune-up bookers)

Touch 3 — the last call (April 21, non-responders only)

Step 3: Capacity planning (the part everyone skips)

A campaign without board space is a promise you can't keep. In March:

• Block tune-up capacity first. Decide how many tune-up slots per day per tech (typically 4–6, since they're 45–60 minutes), and block them on the board for April before anything else books over them.
• Route by density. Batch tune-ups geographically — same neighborhoods, same days. A tech doing 6 tune-ups in one subdivision beats 6 scattered across the county.
• Hold emergency flex. Keep 20% of daily capacity unblocked for no-cool calls. Tune-ups are planned; breakdowns aren't. If the flex goes unused, pull forward the next day's tune-ups.
• Stock the truck. Filters in common sizes, capacitors, contactors, drain-line tablets. A tune-up that finds a weak capacitor should fix it same-visit — that's the upsell that pays for the campaign.

Step 4: The in-home conversion (where the real money is)

The tune-up is a loss leader for three revenue events. Train techs on all three:

• The repair find. Weak capacitor, clogged drain, low refrigerant — documented with photos, priced on the spot, fixed same-visit when possible. "Found it before it failed you in July" is the line.
• The agreement close. Every tune-up customer hears the maintenance plan pitch once, with the math: two tune-ups + priority + discount vs. the monthly price. One ask, no pressure, logged either way.
• The replacement seed (8+ year systems). Not a sales pitch — a status report: "Your system's 11 years old and running fine today. When it goes, here's roughly what replacement looks like, so it's not a surprise." That conversation, planted in April, closes in August when the compressor dies.

Step 5: The heat-wave reactivation (June–August)

When the first real heat wave hits, message the segments that didn't book: "First 95-degree week of the year — our schedule is booking [X] days out. If your AC is struggling, reply NOW and we'll prioritize you." The April campaign built the list; the heat wave is the trigger. Same list, second harvest.

Three mistakes that sink the campaign

• Starting in June. By June you're competing with every other HVAC company's emergency backlog for the customer's attention. April is when they have time to think.
• Discounting without the agreement upsell. An $89 tune-up with no conversion path is just cheap labor. The campaign's profit is in the repairs found, the agreements signed, and the replacements seeded.
• No capacity blocked. Selling tune-ups into a board with no room creates reschedules, and reschedules create cancellations. Block first, sell second.
