Recurring-revenue documentation, ServiceTitan migration, technician retention, financials cleanup, and the KPIs buyers diligence. Sourced. **Author:** Sukhrobjon Ismoilov **Published:** 2026-06-06 **Updated:** 2026-06-06 **Canonical:** https://mainstreetwealth.ai/resources/hvac-exit-checklist This is the operating checklist we run with HVAC owners 12 months before going to market. For a full overview of the trade, see our [HVAC industry overview](https://mainstreetwealth.ai/industries/hvac). For closed-deal patterns, see our [recent transactions](https://mainstreetwealth.ai/case-studies/). The objective of this list is not "hit every box." It is to identify the three to five items where 12 months of focused effort delivers a measurable multiple step. The highest-impact items in each section are listed first. ## 12 months out: financial-records hygiene - **Migrate to ServiceTitan, Housecall Pro, or FieldEdge** if you are still on spreadsheets or homegrown software. Buyers expect SQL-exportable data on customer cohorts, equipment installation history, and recurring-maintenance-agreement waterfalls. - **Engage a Quality of Earnings (QoE) firm** (Aprio, Eide Bailly, or any boutique PE-experienced QoE practice) to produce a sell-side QoE report 6 to 9 months before going to market. The same methodology will be cited by every buyer's diligence team. - **Move from cash-basis to accrual-basis accounting** if you have not already. Most institutional buyers will not accept cash-basis financials. - **Standardize the chart of accounts** so revenue is segmented by category: residential service, residential maintenance agreements, residential install/replacement, commercial service, commercial install, new-construction. - **Reconcile every bank account.** Eliminate unreconciled items. Document any owner-payable or owner-receivable balances. ## 12 months out: recurring maintenance-agreement documentation This is the single biggest multiple lever. Buyers will model the maintenance-agreement book like a SaaS company. Prepare: - **Maintenance-agreement waterfall.** For each of the past 24 to 36 months: starting active agreements, new agreements signed, churned agreements, ending active agreements. - **Customer-cohort retention analysis.** Group maintenance-agreement customers by acquisition year. Show retention rate and revenue per customer per cohort. - **Auto-renewal language audit.** Confirm contract language is enforceable. Some legacy maintenance agreements have no auto-renew clause and are technically year-to-year manual renewals. - **Service-frequency mix.** One-visit-per-year vs. two-visit-per-year vs. quarterly contracts. - **Payment-method mix.** ACH/auto-charge vs. invoice-and-check. Higher auto-charge percentage protects retention metrics. - **Attach-rate trend.** What percentage of installation customers convert to a maintenance agreement at install time? Top operators run >50% attach. For why this matters mathematically, see [how PE values HVAC contracts](/resources/how-pe-values-hvac-contracts). ## 9 months out: licensing and regulatory - **License continuity plan.** State HVAC contractor licenses (CAC in Florida, RMP-equivalent designations in many states) typically must be held by a qualifier on staff post-close. Confirm whether your state allows the seller to remain qualifier during transition. - **Workers' comp X-Mod review.** A clean experience modifier (under 1.0) is a small multiple lift. Above 1.2 is a flag. - **EPA Section 608 certification rosters** for every refrigerant-handling technician. - **OSHA citation history.** Document any citations in the past 5 years and remediation taken. - **DOT compliance** for fleet over 10,001 lbs gross vehicle weight. ## 9 months out: technician and management depth Buyers underwrite the team almost as heavily as the financials. The U.S. HVAC labor market is structurally tight, with **about 37,700 annual openings** projected through 2032 ([BLS](https://www.bls.gov/ooh/installation-maintenance-and-repair/heating-air-conditioning-and-refrigeration-mechanics-and-installers.htm)). - **General manager or operations lead in place.** A non-owner GM running day-to-day removes key-person risk. - **Field-supervisor depth.** Minimum 1 supervisor per 6 to 8 technicians. - **Documented technician training program.** Onboarding checklists, ride-along protocols, NATE certification milestones, manufacturer training (Carrier, Lennox, Trane). - **Compensation transparency.** Hourly + commission structure documented in the employee handbook. - **W-2 vs. 1099 mix.** Most HVAC technicians should be W-2. A heavy 1099 mix invites IRS reclassification risk in diligence. - **Average tenure schedule.** Headcount table by department with start dates, target retention >85% on field staff. ## 6 months out: operational data and KPIs Buyers benchmark HVAC operators on a tight set of operational KPIs: - **Revenue per service technician.** Target $700K+ for platform-quality. - **Average ticket.** Target $1,500+ on residential service. - **First-call close rate** on replacement-quote calls. Target 35%+. - **Maintenance-agreement attach rate** on new installations. Target 50%+. - **Service-call dispatch density.** Stops per technician hour, miles per stop. - **Capacity utilization.** What percentage of technician capacity is currently filled? Buyers pay more when there is organic growth runway in existing routes. - **Truck and equipment audit.** Documented fleet maintenance schedule, fleet age profile, planned capex. ## 6 months out: revenue concentration and customer mix - **Top-10 customer concentration.** Above 15% is a flag; above 25% is a meaningful multiple discount. This is most often a commercial-customer concentration issue. - **Geographic concentration.** Revenue by ZIP / county / metro. Buyers prefer balanced concentration over a single-county business. - **Channel mix.** Direct organic, Google Local Service Ads, Angi, retail referral partnerships, manufacturer-partner co-marketing. - **Lead-source concentration.** Diversification protects the multiple. - **Service vs. install vs. new-construction mix.** Service-led shops trade higher. ## 3 months out: deal-prep and management presentation - **Confidential information memorandum (CIM).** Drafted by your sell-side advisor. Include the maintenance-agreement waterfall, cohort analysis, route-density data, technician roster, and management-team profile. - **Management presentation deck.** Slides for management meetings with shortlisted buyers. Include growth strategy, capex plan, and integration philosophy. - **Anonymized teaser.** One-page summary distributable to buyers under NDA. Used to filter the universe before disclosing identity. - **Buyer list.** Validated against our [HVAC buyer list](/resources/hvac-buyer-list). - **Insurance review.** General liability, professional liability, auto, workers' comp - confirm policies are renewable and properly bound. ## At LOI signing: diligence preparation When the buyer signs an LOI, the diligence sprint begins. The full request list is in our [HVAC due diligence checklist](/resources/hvac-due-diligence-checklist), but the key documents to have queued and ready: - Last 3 fiscal years of financial statements + interim YTD - Sell-side QoE report - Customer schedule with revenue, tenure, and category - Technician roster with EPA 608 / NATE / state license details - Lease agreements for all locations and yards - Top-25 maintenance-agreement contracts - Insurance certificates - HR file: handbook, comp plan, organizational chart ## The 25C credit cliff: why timing matters in 2026 The federal **25C Energy Efficient Home Improvement Credit** that drove a meaningful share of recent heat-pump and high-efficiency-system replacements **expired December 31, 2025** ([IRS](https://www.irs.gov/credits-deductions/energy-efficient-home-improvement-credit)). Two implications for HVAC sellers preparing for 2026 to 2028 close dates: 1. **Pull-forward demand.** Some 2024 to 2025 replacement revenue was tax-credit-driven. Buyers will normalize that out of forward-projected EBITDA. 2. **Service revenue is now more important.** Without the credit tailwind, recurring maintenance and replacement-cycle revenue is what protects the multiple. Owners with diversified service-led revenue mix are insulated; pure-install shops are not. If your business has been heavily install-driven and 25C-credit-enabled, the cleanest move is to spend 6 to 12 months strengthening the maintenance-agreement book before going to market. ## The clean takeaway - **The 12-month checklist is mostly about recurring revenue.** A book at 40%+ maintenance agreements with documented cohort retention is the single largest delta between mid-band and top-band multiples. - **License continuity is the second-biggest avoidable risk.** Sellers who are the only state-licensed qualifier should plan a transition before going to market. - **Diligence-ready data > pretty data.** Buyers do not need a polished CIM if your underlying data is unreconciled. They need exportable transaction-level data they can run through their own QoE process. - **A specialized advisor pays for itself.** The list above is what we run for sellers we represent.
