Your tune-up customers aren't gone.
They're just one season late.
Customer retention software built for HVAC contractors.
HVAC customer retention software can use permitted tune-up, agreement, and equipment-history data to identify cadence drift and prepare targeted outreach. Retention IQ combines Book Value, Drift Radar, Voice Training, and completed-return attribution. Source-system fit is confirmed during the managed launch.
AC tune-ups should be every spring. Heating tune-ups every fall. Filters quarterly. A 12-year-old system is a replacement conversation. Your customers know all of this — but life gets busy, they skip a season, and they show up at the competitor with the better reminder system.
See which customers are moving away from expected service cadence, review the evidence, and approve the next action within the configured campaign workflow.
Pay for verified completed returns. Retention IQ charges a per-return fee (banded by industry — see pricing) when an attributed customer return is verified as completed — not for a click, cancellation, no-show, or uncompleted booking.
What a 90-day plan could look like.
Formula-driven scenario for a typical 1,200-customer HVAC shop with $179 average tune-up ticket and $4,800 average system-replacement ticket. These values are editable assumptions, not customer outcomes.
ServiceTitan / Housecall Pro export uploaded. Customer history parsed. Equipment install dates and maintenance agreements indexed.
Customers 11+ months past last tune-up surface. Per-customer message classifies on-schedule vs. lapsed vs. system-age conversation.
Maintenance agreement renewals at 60/30/7 day pre-lapse fire. Equipment-age (10–15 yr) replacement conversations stage.
Day-end reports show recovered tune-up, IAQ attach, and replacement-quote revenue traceable to specific messages.
Scenario notice: Illustrative inputs only: the displayed rates and service values are planning assumptions, not observed Retention IQ customer results or HVAC benchmarks. Replace them with measured source-system, reachability, completion, and job-value data.
Every job has a follow-up window. We're watching it for you.
We know roughly when each customer's next service is due — and we reach out before they Google "HVAC near me" because the AC stopped cooling.
Fire late February. Book before the first 90° day jams your schedule.
Fire early September. Catch the customer before the first cold snap.
Pluggable into a subscription. Pulls work forward and trims call-volume on dirty-coil failures.
Equipment age tracked from install record. The "before it fails on a holiday" conversation gets staged early.
One problem you can see. One you can't.
About 40% of past customers are dormant right now.
They called you once for a fix two summers ago. The unit's working. They never thought about you again. Then their neighbor's HVAC guy hung a magnet on their fridge and now that's who they call. We bring them back before that happens — with a spring tune-up reminder that lands in their inbox the week the temperature swings.
Shoulder seasons run 30% under peak utilization.
April and October are dead in most shops. Techs get sent home. Trucks sit. The pattern — utilization quietly slipping in shoulder weeks — nobody notices until it's already the month's P&L story. We surface it tomorrow instead of next month.
The quotes you already sent and never heard back on.
Every shop has a folder full of estimates that went out and went quiet — the $6,800 system swap the homeowner "needed to think about," the compressor job they meant to schedule. They didn't say no. They got busy. Closing a job takes 8–12 touches; most shops stop at one. Retention IQ watches your unsold estimates and runs the follow-up you never have time for — from data already sitting in your field-service system.
Industry data across 160,000+ HVAC follow-up campaigns shows roughly 6 in 10 stale estimates answer a structured SMS-plus-email sequence.
Rehashing unsold quotes already in your FSM system books work at a fraction of the cost of chasing a brand-new lead.
The gap between one follow-up and a full sequence is the difference between a lost quote and a booked install.
Unsold estimates can represent meaningful pipeline, but the value is specific to the shop, ticket mix, and close rate. Retention IQ can surface deferred estimates from the agreed data source and prepare the next touch for review without presenting a generic revenue promise.
Open the app. See who's due today.
"Hey Mike — it's about that time again. Your AC tune-up from last April puts us right on schedule. Got Tuesday and Thursday open this week. Want me to swing by? Tom"
"Hi Linda — heads up that your Gold maintenance plan renews July 22. You still have one visit included this term — want to use it before then? I have a few openings the week of June 24. No rush, just wanted to keep you ahead of it."
Drafts use the permitted customer history available to the campaign. Production delivery is activated only after the sending system, consent evidence, suppression rules, and opt-out handling are verified; the customer controls campaign approval.
Speaks your service catalog, not "business in general."
It knows a heat-pump customer in the Carolinas needs a different cadence than a gas-furnace customer in Minnesota. It knows IAQ add-ons land best 30 days post-tune-up. You don't have to teach it.
Service-category tracking
- Tune-ups & maintenanceSpring AC and fall heating. Per-customer cadence, climate-zone adjusted. Combo-package customers tracked together.
- Maintenance agreementsGold/silver/basic, monthly/annual, single-system/dual. Pre-lapse outreach at 60/30/7 days.
- Indoor air qualityFilters, UV lamps, humidifiers, ERV/HRV. Tracked on replacement cycles, sold as cross-sell after a clean tune-up.
- Equipment age & replacementInstall records tell you when the 10-year conversation should happen. We stage it before the failure call.
- Repair-to-replace conversionRepair history flags customers whose next service call should be a replacement quote, not another patch.
Operator intelligence
- Per-tech scorecardsService techs, install techs, lead techs, apprentices — each with benchmarks specific to their role. Fair across the board.
- Cross-sell that isn't pushyTune-up customers ready for an IAQ upgrade. Repair customers approaching replacement age. The engine knows which pairings actually convert.
- Off-season demand smoothingApril and October open weeks get prioritized in outreach. The engine pulls tune-ups forward into idle capacity instead of into August chaos.
- Maintenance plan modelingTest what restructuring your Gold plan or adding a Platinum tier would do to MRR before you announce it.
- Discount guardrailsIf a customer is on schedule, we don't suggest a coupon — they're coming anyway. If they're 18 months late, we might. You set the rules.
No rip-and-replace.
We connect in one of two ways: a weekly CSV export, or a direct integration where available. Your dispatch and invoicing stay exactly as they are today.
