I had a great experience with Energy Savers of Columbus Georgia. We purchased an HVAC unit from them in the past. The unit was making a lot of noise and stopped working. It was one of those days where it was about a hundred degrees outside. I called their shop and they quickly sent a technician. He was friendly, immediately diagnosed the problem, discussed the possible solutions, and then fixed it. He knew what he was talking about and I was glad to have it fixed. I would recommend their service.
