HVAC tune-up email templates for fall and spring

The time to fill the board with tune-ups is six to eight weeks before the season turns, while you still have room. A three-email sequence to past customers is a simple way to do it, as long as it gives a real reason and a real deadline. This prompt writes all three.

What to get right

  • Start early. Six to eight weeks before heating or cooling season, before emergency calls crowd out maintenance.
  • Give a real reason. Catching a cracked igniter or a weak capacitor before the first cold night or heat wave. If your manufacturers’ warranties call for regular maintenance, say so.
  • One offer, one deadline. A price and an end date you’ll actually keep.
  • Different list, different email. Members get a reminder to book, not a discount pitch for something they already pay for.

How to use it

  1. Pull past customers who aren’t members, and members, as two separate lists.
  2. Fill in the season, the offer and the deadline.
  3. Add reasons for a tune-up your techs would stand behind.
  4. Run the prompt and schedule the three emails about a week apart.
  5. Have the office call anyone who opened but didn’t book.

A tool that can help
