Dupont Heating & Air Conditioning Ltd

Micheal from Dupont Heating came to clean furnace. He spent about 1/2 hour doing this. He did a check list of everything he did: thermostat operating, checked venting, piping, burners, cleaned blower and checked operating, checked heat exchanger, filters checked. and CO levels He said the furnace was working well and that I did not need a new one for a while. Very satisfield with the work.
