I used Howard Katzman to conduct a home energy audit. He was timely, thorough, and answered all of my questions. We were originally going to get 2 new HVAC systems, but after working closely with Howard and using his results and recommendations, we only had to get one new HVAC and spent our limited resources on insulation and other home improvements to save on energy costs. He also took care of all of the paperwork to process our GA Power credit. He was great to work with and I highly recommend him.
