Check energy efficiency programs to find a preferred contractor. For example, the San Francisco Energy Watch Program has a list of preferred contractors. These contractors have been evaluated for green efficiency and meet professional criteria standards set by the program to be included on their website. This site can help a homeowner update their home for energy efficiency with heating and cooling. Visit your state's environment protection site or a green business directory to locate a preferred contractor.
Research options on Internet sites that list preferred contractors that have been evaluated by a third-party company. For instance, the Owens Corning Roofing website and ServiceMagic.com offer background-screened preferred contractors for a variety of services. For example, you can find a preferred plumbing contractor or roofer. These sites are designed to give consumers confidence and save time in finding quality licensed contractors.
Find a preferred contractor online from customer reviews posted online with their contact information. Angieslist.com is a great example because this site provides insight into the customer experience. Furthermore, their responses give you an opportunity to reach out to ask additional questions by simply clicking a button to contact them. This allows the prospective client to assess their own preferred contractor with first-hand feedback.
