BUILDING PERFORMANCE DIAGNOSTICS INC

At the time I had the energy audit performed (February 2010) Georgia Power offered a $200 rebate through the Energy Star Program for a home energy audit performed by one of the companies listed on Georgia Power's website. I reviewed and obtained quotes from the five "assessments only" companies (instead of ?assessments and improvements? companies) listed on Georgia Power's website. I picked Building Performance Diagnostics based on my discussion with the owner, Sandy Herrera ? the price quotes from four of the five companies were about the same and were based on square footage of the house. During the call Sandy asked what my goals were for the energy audit and I explained that while interested in energy efficiency, I was more concerned about the draftiness of the house during the winter time. Sandy was very patient in explaining the tests he would conduct for the energy audit, how these tests would identify the causes of the drafty conditions in the house, how long the tests would take (about 5 - 6 hrs), and the report he would create and explain in a follow-up visit. Sandy was fantastic, very professional, knowledgeable, efficient, and thorough. I noticed his equipment was well maintained and he carefully explained everything he was doing, and was very patient in answering all of my layman questions. He even let me use his thermal camera while he did some of the tests so that I could understand how the camera identifies where cold air (February!) was leaking into the house. After Sandy completed the energy audit he immediately scheduled a follow-up visit to discuss the report he would create. Sandy did have to reschedule the follow-up visit once due to running behind schedule on another energy audit, but he called early enough that it had no impact to my busy day and it was no problem rescheduling for a few days later (and he was willing to meet in the evening so that it didn?t impact my long commute). The report Sandy created was very informative and detailed and he spent about an hour and a half reviewing it with me. The report listed the results of the tests he performed, such as ?air exchanges per hour? within the house, as well as the specific points throughout the house that were allowing air to leak in and out. He also had data on how inefficiently my HVAC system and duct work were moving conditioned air around the house and how I could fix that. Sandy also provided one-page ?fact sheets? on things like Radiant Barriers and Air Sealing that were very educational and explained how I could correct the issues identified through the energy audit. All in all I was extremely pleased with Sandy?s work and everything I learned through the energy audit that -- once I fix things -- will make my home more efficient and more comfortable.

They were very good. They were very knowledgeable and thorough. They gave us advice and helped us save energy.

Sandy and his assistant stayed at our home for half a day, arriving when they said they would. They were patient about having to move some furniture to get to some of our hvac ducts for testing. Sandy came back to meet with us in person to go over the results. He has been incredibly generous with his time in helping us evaluate the bids we got, all of which proposed different solutions to our problems.
