“Pest control's 85% annual retention vs. HVAC's 65–70% service agreement renewal is the primary driver of the multiple premium. Retention rate is earnings persistence — and buyers pay directly for it.”
Why Pest Control Commands Higher Multiples Than HVAC
Both pest control and HVAC provide recurring home services, but pest control businesses consistently command higher SDE multiples than comparable HVAC businesses. The reason is not revenue size — it is revenue retention mechanics. Pest control recurring revenue is driven by ongoing pest pressure: the customer's home has ants, roaches, or termites now, and will continue to have them without regular treatment. The service continues because the pest problem continues. HVAC service agreements are driven by maintenance need — customers renew them when they believe the equipment is at risk, but many HVAC customers allow service agreements to lapse without incident. The annual retention rate for pest control recurring customers (75–90%) consistently exceeds HVAC service agreement renewal rates (60–75%).
The Retention Rate Multiple Relationship
The multiple buyers pay is a function of earnings persistence — how likely is it that this year's earnings will recur next year? Higher retention = higher persistence = lower risk = higher multiple. A simple illustration: a pest control business with 85% annual retention and a 5-year customer lifetime has a much more predictable earnings stream than an HVAC service agreement business with 65% renewal rates. The buyer of the pest control book can model earnings 3 years out with reasonable confidence; the HVAC buyer faces more uncertainty in each successive year. This difference in earnings predictability is reflected directly in the multiple premium.
HVAC Service Agreement Quality Variation
Not all HVAC service agreement books are equal. HVAC businesses with: high service agreement penetration (40%+ of revenue from service agreements); multi-year agreement terms (2–3 year agreements with auto-renewal); comprehensive coverage (parts, labor, and efficiency tune-up included); and residential customer base with above-average income (higher renewal willingness) — these HVAC books approach pest control recurring revenue quality and trade closer to the pest control multiple range. HVAC businesses with low service agreement penetration or predominantly replacement and installation revenue trade at lower multiples reflecting the project-revenue discount.

The Combined Pest and HVAC Buyer Market
Home services platforms — PE firms building diversified residential service companies — are one of the few buyer categories that value pest and HVAC together at close to full multiple for both service streams. These platforms are building toward 'total home services' models where a single customer subscribes to pest control, HVAC service agreements, plumbing inspection programs, and other recurring services. For sellers of combined pest and HVAC businesses, identifying home services platform buyers (vs. single-service pest control buyers) is critical to achieving full value for the HVAC component.
