Your AC's last tune-up was {{months_since_service}} months agoHi {{client_name}},
Quick heads-up from your calendar, not ours: it's been {{months_since_service}} months since we last serviced your system, and {{city}}'s first 90-degree week usually lands around {{first_hot_week}}.
That's when our schedule fills with emergency calls — and when a worn $40 part turns into a $900 breakdown on the hottest day of the year.
A {{tune_up_price}} tune-up now takes care of it.
Here's exactly what's included, so there are no surprises:
- Full 21-point inspection ({{checklist_link}})
- Refrigerant levels checked and coils cleaned
- Capacitor and electrical connections tested
- A straight answer on how your system is doing — and nothing sold that you don't need
Right now we can get you in within 2-3 days. Once the heat arrives, that wait stretches to two weeks.
Next step: Pick a time that works for you here: {{booking_link}}
Or just call or text us at {{phone_number}} and we'll find you a slot — mornings and afternoons both open this week.
Stay comfortable,

When To Send This Email
Trigger
A past residential customer is 11-18 months from the last cooling-system service and has not booked a spring tune-up.
Timing
Send 4-6 weeks before the local historical first 90-degree week, during the shoulder-season scheduling window.
Frequency
Send once, then one checklist-led follow-up 7 days later if no appointment is booked.
Timing note
Use actual local weather history and current appointment lead time; never invent a heat wave or schedule shortage.
Why This Email Works
Personalization Notes
- Populate months_since_service from the completed-job record, not a guessed date.
- Replace first_hot_week with a locally defensible seasonal reference and remove it if the data is unavailable.
- Link the operator's real inspection checklist and use the current tune-up price and booking capacity.
Platform Setup Steps
Trigger
Last completed cooling-system service date reaches the configured pre-season interval and no future tune-up appointment exists.
Segment
Residential customers with a completed AC service, valid email consent, and no open complaint or active booking.
Delay
Queue 4-6 weeks before the local cooling season; suppress immediately when an appointment is created.
- Map last service date, system type, city, and booking status from the service record.
- Insert the current checklist, price, booking link, license number, and truthful appointment lead time.
- Assign replies to the service coordinator and create a booking task when a customer requests help.
Stop conditions
- Stop when the customer books, replies, opts out, or enters an active service workflow.
- Suppress contacts with unresolved complaints, invalid service history, or missing consent.
- Do not send the follow-up if the seasonal timing or current capacity claim is no longer accurate.
Compliance / Risk Notes
- Use only verified prices, license numbers, service dates, checklist items, and schedule availability.
- Avoid stating that maintenance prevents every failure or guarantees energy savings, warranty coverage, or equipment life.
- Honor consent and opt-out requirements and suppress customers with an unresolved service issue.
Subject Line Variations
- Your AC's last tune-up was {{months_since_service}} months ago
Service-history specificity makes the reminder feel earned.
- Before {{city}}'s first hot week: your AC checklist
Use when the checklist is the strongest trust asset.
- Spring AC appointments are open in {{city}}
Use when service history is unavailable but the seasonal segment is verified.
Mistakes To Avoid
- Manufacturing a heat wave or two-week wait
False urgency damages trust and can make the promotion deceptive.
Use instead: Use current capacity and a defensible local seasonal window, or remove the urgency sentence.
- Calling every tune-up a breakdown-prevention guarantee
Maintenance reduces risk but cannot eliminate equipment failure.
Use instead: Explain what is inspected and frame early detection as a possibility, not a certainty.
