Every HVAC contractor knows the pattern. The first 90-degree day hits and the phone goes nuclear. Everyone needs AC service right now. You're triaging, sending techs to the worst cases first, and telling everyone else to wait. Meanwhile, the customers who would have happily booked a tune-up in April never called because they forgot.
The contractors who avoid this chaos don't have bigger crews or better equipment. They have a system that starts in February.
February and March: Build the list
Pull every customer from last summer's service calls. These are your tune-up candidates. Their system is a year older, and they already trust you. Send them a text in March: "It's tune-up season. We've got openings in May. Want us to lock in your spot?"
The key is the timing. March is early enough that they haven't started thinking about AC yet, but late enough that they'll say "sure, why not." By May, they're too busy to care. By June, they're calling you with a broken system.
April: Confirm and schedule
Follow up with everyone who didn't respond in March. A second touch a month later catches the people who meant to reply but forgot. This is also when you start filling specific time slots. "We've got you down for Tuesday, May 14, between 9 and 11. Does that work?"
A specific time slot gets more confirmations than "when works for you?" because it reduces decision fatigue. The customer just has to say yes or propose an alternative.
May: Execute with a full calendar
If you did February through April right, May is a smooth, profitable month. You've got a calendar full of tune-ups, your techs have predictable routes, and you're not in panic mode.
This is also when you start the review pipeline. Every tune-up customer gets a text the same day: "Thanks for choosing us. If we did right by you, a quick Google review helps us a lot." Those reviews compound into better map pack rankings, which means more calls when the real heat hits.
June through August: Handle the rush
When the emergency calls start flooding in, you want two things: a calendar that's already generating revenue from tune-ups, and a system that catches every call — including the ones that come in at 9pm or while your tech is on a roof.
The contractors who survive summer without burning out are the ones who built the pipeline in spring. Everyone else is just reacting.
The checklist
- February: Pull last year's service call list. Segment by system age.
- March: Send first tune-up outreach via text. Offer specific May dates.
- April: Second touch to non-responders. Lock in time slots.
- May: Execute tune-ups. Trigger review requests after each job.
- June: Emergency calls start. Make sure every missed call gets an instant text back.
- July-August: Survive. Then start the whole cycle again in September for heating season.
The difference between a summer you survive and a summer you thrive through is about 90 days of prep. Start early.
