In recent years, home improvement centers have dramatically changed the residential building market in terms of product sales and installation, most notably in the cabinet and countertop, flooring, and roofing segments. Now, in an increasingly competitive market, they have targeted both residential and commercial sales, installation, and service markets as an area for growth and expansion. This movement has both current and potential impact on the construction industry. This study examines trends and drivers that will impact future scenarios, specifically for the HVAC industry and the union segment of the trade. The research was developed through a combination of interview and surveys with HVAC industry stakeholders and an in-depth literature scan of private and public documentation, trade press, and industry reports.
