Whole-House Approach

GreenHomes America offers home improvement solutions that increase in-home comfort, health, and safety and significantly reduce energy usage and utility bills. We apply building science principles and sophisticated diagnostic equipment to quickly pinpoint causes of common problems and prescribe cost-effective solutions that resolve them permanently. 

What sets GreenHomes apart from the many other residential building contractors starts with our innovative use of an integrated, whole-house approach to home performance and energy efficiency.  Our trained certified staff use state-of-the-art diagnostics to find the real problem, we work with you to put together the project that makes the most sense for you and your family, our own in-house technicians install the work--whether you need a furnace, windows, or insulation and air-sealing, and we "test-out" at the end of the project to verify the results.

Our unique HPC methodology allows GreenHomes to go beyond the usual HVAC and specialty contractor guesswork and quickly and accurately solve a home’s comfort and energy efficiency issues.  With our unique methodology built on strict adherence to quality, process, technology, education, and standards, GreenHomes raises the bar on service delivery for the entire industry by consistently providing high quality service to every customer, every time.  And we back this up with industry-leading guarantees.  Ask one of the more than 10,000 families we've helped!
