One of my really good friends got into business over the summer and bought a brand new hydro master, direct drive from Jon Don. I've been very impressed with the business he has been able to generate. He is avoiding all of the mistakes I've made over the years. He is about the third person I have put into the carpet cleaning business. He has done all of the right things as far as heating his truck in the cold winter months, two heaters running at night. So, today he calls me from a customer's home and says his heat exchanger was shooting water all over the place. We were able to assist him in getting the job done and retaining the customer. The problem I see that it was never told to him that there is a dog house containing all of the major componets- heat exchanger, pump, etc. that was getting no heat from his heaters and all of the cold air from the outside. If he would have removed his dog house, he would have been fine. Why was this not disclosed to him???? Guess who gets to eat the cost?? Wrong IMO!
