About This Market
Hammond's HVAC market serves a mix of older residential stock and industrial facilities near the steel mills. Summers hit hard here with humidity off Lake Michigan, driving steady AC demand. Winter heating loads are significant. Competition is moderate with about 25-30 active contractors serving the metro area. Costs run slightly below Chicago but above rural Indiana due to union presence and industrial work. Hammond sits in Lake County with stricter environmental regs than downstate. You'll need your Indiana contractor license - no shortcuts. City permit process is straightforward but they inspect everything. Peak season runs May through September when everyone's AC dies at once. Industrial clients pay better but expect 24/7 availability. Residential work is bread and butter but price-sensitive. Winter heating emergencies keep you busy when others slow down. Know your way around older boiler systems - lots of houses here still run them.
