They're expensive, they really are. I believe that Carolina Heating & Air thinks that they're going to sell me my next air conditioner, but I've got news for them, they're not. I actually purchased a whole house generator from them about four years ago. That thing, wasn't cheap. I signed up for a maintenance agreement for them to come out and service it last year and if I had to have any repairs, they would knock so much off. But they are very, very expensive. So when it comes time to get me a new air conditioner, it's not going to be purchased through Carolina Heating & Air. They are so expensive and they're expanding out into Geothermal stuff and solar stuff. You know what happens when companies expand, the service in other areas start to get slack. It hasn't yet, but I see it coming in the future. They just get too big for their britches, they really do. I was pleased with them, they've got one technician that I ask for every time. He is efficient, he is amenable, he gets the job done and I like him. That's the one I ask for. As a matter of fact, I schedule my appointments around him. If he can't see me, then unless there is an emergency, I just wait until he has an opening in my area. That's how much I like that one technician. It's $500 a year, for the generator and the heating and air conditioning agreement. It's kind of pricey, but you're supposed to get priority service over people who don't have it. I really like that they call you and let you know that they're on their way out. If something should happen and they can't make it in the time frame, they will call you. I really like that. Old folks like stuff like that. Younger folks like it too for that matter because time is very valuable to younger folks.
