About This Market
Troy's HVAC market runs hot with steady residential replacement demand and growing commercial work from the tech corridor. Competition is fierce among Michigan's 2,574 licensed establishments, with pricing driven by equipment efficiency ratings, home size, and ductwork complexity. Most residential jobs involve replacing 15-20 year old systems in established neighborhoods, while new construction focuses on high-efficiency units meeting current energy codes. Emergency calls peak during temperature extremes, creating premium pricing opportunities. Getting licensed in Michigan means navigating LARA's bureaucracy and passing their mechanical contractor exam - not a weekend project. Troy's building department runs tight inspections and expects clean installations that meet current mechanical codes. Smart contractors build relationships with local supply houses for competitive equipment pricing and stock emergency parts for common systems. Peak installation seasons are short but profitable if you're positioned right. Emergency service calls separate the profitable shops from the parts changers.
