About This Market

UPDATED APR 2026

Salem's HVAC market runs steady year-round with 720 licensed establishments statewide creating solid competition. Residential replacements dominate the work - older homes need constant furnace and AC upgrades, while new construction stays busy in the southern NH corridor. Costs run 10-15% higher than state average due to proximity to Massachusetts markets and higher labor costs. Emergency calls pay premium rates during temperature extremes. Getting licensed in New Hampshire means passing the state exam and proving your experience - no shortcuts. Salem building department runs tight inspections, especially on gas work. Peak season splits between summer AC failures and fall heating prep. Smart contractors stock common parts for emergency calls and build relationships with local supply houses. Winter emergency work pays best but tests your skills when systems fail at 2 AM in subzero weather.
