I have used HVAC Warehouse for the past five years, and my total satisfaction is what keeps me coming back. The first time, I was a novice and didn't know what I was looking for, but the sales manager showed me the options and helped me find what I needed. I am pleased with my hot water heater, and the three mini splits cool my house quite nicely. When he comes out, Richard asks to use my little ladder, so he doesn't have to bring his big one. It's a nice personal interaction. I have never had a problem scheduling with them, and just called them last week, in fact! I understand they are offering plumbing services now, too, so when I need those, I'll be calling HVAC Warehouse to come out.
