Jason was a life saver at 1:00 am to drive in a rain storm to calm my worries of a possible gas furnace smell. After examining all the furnace parts he concluded I was safe and the awful smell was not connected. He then assured me he would require another tech to come in the morning and do more inspections.. After more searches it was decided the smell was coming from a dead animal outside and coming thru a crack in my basement wall. The animal has not been found as yet but will be removed in the next couple of days..
Thank you Harker Heating for all your help.
