Like the other review said, they are very friendly and great to talk to... That is until, you give them your money, and then you can't get in contact with them. They kept giving my wife the run around. And they also told us that we would get free tune ups for as long as we have their heater... apparently you don't, they will just say what they have to in order to get the sale. What a bunch of bull crap! (This website made me edit how the real word I used) Stay away from them!
