Customer Testimonials

No company in the field of building energy science is more conscientious and consumer oriented than you, and few know what it takes to make a building perform as it should.
- David, Lake Lure, NC
I’ve had numerous meetings with building inspectors and contractors, and all are amazed at the quality of your system and convinced that this technology is the pinnacle of the future of HVAC systems for residential projects.
- Jerry, Mebane, NC
We’ve used your systems on three different projects and the results have been astounding! There has been a significant reduction in our heating and cooling cost at our beach house. More importantly, the temperature is uniform throughout the house, regardless of the season, and the house has a clean, comfortable feel. The days of hot upstairs bedrooms in the summer are over.
- Tom and Frieda, Wilmington, NC
Since purchasing the home, I’ve been impressed with the quality of HVAC system, insulation and energy consumption. Our 6,000 square foot home is 100% electric and very cost effective ─ with a 67% reduction in electric consumption after your work. We love the house, admire its efficiency and are overly impressed with SED’s commitment to customer service, quality, and professionalism.
