What the Data Tells Us
IBISWorld publishes a 2026 heating-and-air-conditioning contractor estimate and 2021-2026 CAGR for a category covering installations as well as service work. The ongoing year is not a completed observed total. Census location-size data include plumbing and exclude nonemployers.
ServiceTitan's 2019-2021 heat-wave analysis separates call and revenue effects within a vendor cohort. Its summer study window and named dispatcher case do not establish national seasonal revenue share or scheduling-challenge prevalence.
Published commercial diagnostic fees, maintenance subscriptions and individual repair tickets cover different work and cannot establish national emergency-versus-planned revenue ratios.
The broader homeowner survey concerns hiring influence, not HVAC booking-channel preference. Named contractor workflows show possible uses without establishing industry adoption.
Named contractor results reflect bundled operational changes. Routing documentation describes estimated travel and job ordering without isolating a causal productivity effect.
The broader consumer survey includes late-arrival frustration. Published tracking and reminder policies do not measure complaint or missed-appointment reductions.
ServiceTitan found a 14.1% average off-hours share of inbound residential HVAC calls in June 2025 in its participating contractor cohort, supporting the value of after-hours booking access without establishing a national annual rate.
