About This Market
San Antonio's HVAC market runs hot and heavy. With 100+ degree summers lasting five months and a metro pushing 2.5 million people, demand stays consistent. New construction drives ductwork jobs, but the real money's in replacements - units die fast in this heat. Competition's fierce with 400+ contractors in Bexar County alone. Costs run 10-15% below Dallas/Houston due to lower labor costs, but material prices hit everyone the same. Commercial work pays better but residential volume keeps the lights on. Getting licensed in Texas isn't a joke - TDLR runs a tight ship and the trade exam has a 60% pass rate. San Antonio adds its own permit layers, and inspectors know their stuff. Peak season starts in April when the heat hits, and emergency calls can triple your normal rates. Winter's slow but that's when smart contractors chase new construction and maintenance contracts. Keep your insurance current and your license clean - one complaint to TDLR can shut you down fast.
