The US HVAC market hit $134 billion in 2025 and is projected to cross $145 billion in 2026 according to IBISWorld. Four forces are driving this and all four favor a new entrant. First, the federal Inflation Reduction Act is still pushing heat pump tax credits of up to $2,000 per household plus stacked state rebates in 17 states.
Second, the average age of US residential HVAC equipment crossed 14 years in 2024 per the Department of Energy, meaning the original wave of stimulus-era high-efficiency systems is hitting end of life right now. Third, the EPA phasedown of HFC refrigerants accelerated in January 2026, replacing R-410A with R-32 and R-454B as the residential standard and making older system repair more expensive.
Fourth, the Bureau of Labor Statistics projects 6% job growth and 37,700 annual HVAC openings through 2032, leaving room for new operators to take share. This guide walks through exactly what it takes to launch a profitable HVAC business in 2026, from passing your EPA Section 608 universal exam to landing your first 20 service calls to building a $400K+ first-year operation.
