INDUSTRY RESULTS · NOT OURS
What reactivating past customers did for other HVAC shops.
These are other companies’ published case studies, not Second Season results. We have no client results yet. Each one shows HVAC shops making money by re-contacting customers they already had. All numbers are self-reported by the vendor or agency that published them, checked against the live page on Oct 29, 2026.
Four public case studies, with links.

What they have in common.
- They started from the shop’s own customer list, not new leads.
- The best-responding groups were warm ones: unsold estimates (5.5% response in the Superior Air study) and customers with aging equipment.
- Campaigns were timed to the season: pre-fall tune-ups and heating checks.
How to read these numbers.
Vendors publish their best results. Most of these used SMS and voicemail as well as email, and some ran alongside ads or call answering, so the numbers are not a forecast for an email-only campaign. Second Season runs email only. That is why our sprint has a profit-based refund guarantee for eligible shops instead of a promise of revenue.
