I got them in to service my furnace, AC, and replace the AC condensate pump. The guy was here on time, was extremely thorough, took his time, explained things to me, and most importantly, did an excellent job. The air conditioner that was so noisy, I thought it needed replacing, is now quiet and cool, and the furnace fan is much quieter too. When I asked a service guy from a different company about the noisy furnace fan, they said "they get like that" and "might be almost time to think about a new one". I will definitely be using these guys again.
