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.

No. Members already paid for the visit. Send them a reminder to book, and save the offer for past customers who aren’t members.
What should a tune-up email say?
One helpful tip, what the tune-up includes, the price and the deadline. Under 120 words, with a short subject line.
