About This Market
Louisville's HVAC market runs steady year-round with 1,335 licensed establishments across Kentucky competing for work. Summers hit hard with high humidity driving AC demand, while cold winters keep furnace work flowing. Residential replacement jobs dominate, but commercial work from healthcare facilities and manufacturing keeps larger contractors busy. Costs run middle-of-the-road compared to coastal markets, with equipment availability and local competition keeping prices reasonable. Material costs and supply chain issues have pushed prices up 15-20% since 2020. The market supports both small residential shops and larger commercial outfits, with enough work to go around during peak seasons. Getting licensed in Kentucky means dealing with the Division of Plumbing, not a dedicated HVAC board. You need four years experience or completed apprenticeship before you can even sit for the exam. Louisville Metro runs their own permit system, and inspectors know their stuff - don't try to cut corners. Peak season means May through September for cooling, but smart contractors build relationships for year-round service contracts. Insurance requirements are reasonable, but make sure you're covered properly. The biggest challenge is finding skilled techs - labor shortage is real here like everywhere else.
