"Sam Marsala was very good at diagnosing my furnace trouble, the fix was simple to my relief. My water heater was on its last legs. Sam diagnosed the trouble and we had Sam install a new Raheem water heater. He was very quick to respond to my needs and explained very clearly the trouble found. Installation was really done neatly and he left the work area very clean. I am more then satisfied with the work, product and technician. Well done."
