About This Market
Detroit's HVAC market runs on replacement work—aging housing stock and industrial buildings drive steady demand. With 2,574 licensed establishments across Michigan, competition is solid but not cutthroat. Residential jobs dominate, focusing on furnace and AC replacements in homes built 1940s-1980s. Industrial work around the auto sector provides higher-value contracts but requires specialized expertise and higher insurance limits. Material costs hit hard here due to supply chain issues, and customers expect financing options. Peak season splits between summer cooling emergencies and fall heating prep—smart contractors book maintenance contracts to smooth out the seasonal swings. Michigan's licensing requirements are straightforward but enforce them strictly. Get your mechanical contractor license through LARA first—no shortcuts. Detroit's permit process is reasonable if you know the inspectors and pull permits properly. The city's been cracking down on unlicensed work, so keep your paperwork clean. Winter emergency calls pay premium rates, but summer AC failures are where you make your numbers. Focus on maintenance contracts with commercial accounts—they pay on time and provide steady work year-round. Know your refrigerant regulations cold; EPA violations will shut you down fast.
