A-1 Service Masters are the very very best on Staten Island. Stanley Zahn is a very curtious man and so his worker Joe. I had them replace my Air conditioner and Furnace at the same time 3 years ago. Well today is August 28, 2009, I called Stan and he came with Joe and installed a new hot water heater and they were so professional that I would recommend them over and over again to people I know. Excellent job Stan and Joe I give you a 5 star rating on here (WORLD CLASS). I hope you stay in business for many more years.
