BEWARE: While installing a new Combination Boiler/Hot Water Heater, Stan Perkoski was careless/negligent and (1) destroyed my basement carpet by spilling grease/home heating oil, (2) broke/damaged/stained numerous basement ceiling tiles, (3) left one end a live 120 volt wire exposed and unattached in the heating room, and (4) damaged the chimney cover. After all that, they did not install a gas line to the stove and the boiler did not work properly. They are horrible and do not stand behind their work!!! DO NOT USE!!!
