You installed the generator — then never contacted the customer again. The reminder campaign that turns installs into service plans: annual texts, pre-storm test runs, and the battery upsell everyone forgets.
System 7 from the Leveraged Owner Starter Pack
A whole-home generator is a $10,000+ machine that sits idle 360 days a year — and fails on day 361 because nobody maintained it. The installer who sold it has a moral and commercial obligation to keep it running, and a reminder system turns every past install into annual recurring revenue. Here's the campaign: the service-plan text, the pre-storm test run, and the battery upsell. For the install-side follow-up, see generator installation estimate follow-up. Keep every service visit locked in with appointment confirmation texts.
Generators need annual service — oil, filters, valve check, full load test. The reminder text sells the service plan, not the single visit:
Annual generator service reminder:
"Hi [Name], [Business] here — it's been about a year since your generator was serviced. A generator that sits unmaintained is the #1 reason they fail when the power actually goes out. Our annual plan covers the full service, the load test, and priority dispatch if it ever faults — [price]/year. Want me to get yours scheduled? Reply GEN and I'll set it up. Reply STOP to opt out."
Sell the plan, not the visit — "priority dispatch if it ever faults" is the line that converts, because every generator owner has imagined the outage where it doesn't start.
Concrete takeaway: the annual text sells the service plan with priority dispatch as the closer. Plans beat visits for retention and revenue.
Storm season is the second trigger — and it's time-bound, which makes it urgent. Send 2–3 weeks before peak storm season in your market:
Pre-storm test-run text:
"Hi [Name], [Business] here — storm season is [X] weeks out. Quick checklist before it hits: (1) run your generator's manual test cycle this week — if it faults or won't start, tell me now, not during the outage; (2) check the battery terminals for corrosion; (3) make sure the area around the unit is clear. If the test cycle throws any error, text me a photo of the display and I'll diagnose it. Reply STOP to opt out."
This text is pure service — no pitch. That's deliberate: the goodwill it builds is what makes the annual plan renewal automatic, and the fault reports it generates are service calls.
Concrete takeaway: pre-storm text is pure service, no pitch. The fault reports it surfaces ARE the revenue — and the goodwill renews the plan.
The most common generator failure point is the battery — a $150 part that kills a $10,000 machine. Batteries last 2–3 years; nobody tracks that except you:
Concrete takeaway: tag the battery date, text at 30 months. The cheapest part prevents the most expensive failure — say so plainly.
While you're building the program, add the transfer-switch inspection to the annual service — it's the component homeowners never think about:
Concrete takeaway: name the transfer-switch test in the plan. Documented circuits, re-verified yearly — renovations change the load picture.
The modern standby generator phones home — cellular or Wi-Fi modules report exercise results, battery voltage, and fault codes to an app. Most installed generators don't have monitoring enabled, and most owners don't know it exists. The upsell is simple: "For [amount], we add remote monitoring — we see the same alerts you do, and we call you before a dead battery becomes a dead generator in an outage." Prevention, sold as vigilance.
The real product isn't the module; it's the watched service behind it. Offer monitoring as a subscription: monthly fee, you watch the alerts, annual service included, priority dispatch in outages. The customer buys peace of mind; you buy recurring revenue and a dashboard showing every generator in town that's about to fail. When the alert fires, the service call is already sold — you're calling to schedule it, not to pitch it.
Lead with the battery story, because it's true and it's vivid. The number-one cause of generator failure in an outage is a dead battery — a $200 part that kills a $12,000 investment. Monitoring catches the voltage drop weeks early. "Your generator's battery is dying" is a text the customer is glad to get, and it's the call that proves the subscription's worth every year it fires.
Concrete takeaway: quote remote monitoring on your next five generator services and track take-rate. The dead-battery story closes it.
At 30 days, check the monitoring quotes: how many went out, and did the dead-battery story get told? The upsell is new enough that techs will skip it without a prompt — put the monitoring line on the service checklist so it's offered by default, not by memory. Track the take rate from day one; it's the number that decides whether this becomes a program.
At 60 days, review the first alert responses. Did any monitored unit throw a battery or fault alert, and did the call go out same-day? The first "we caught it" story is the proof of the whole program — document it, get the customer's permission, and turn it into the testimonial that sells the next twenty subscriptions.
At 90 days, look at the subscription base: how many monthly monitoring plans are active, and what's the churn? Early churn usually means the value wasn't explained at sale — the customer thought they bought a gadget, not a watched service. Tighten the sale language around "we watch it for you" and the retention problem mostly disappears.
