Waste Oil Doctor has been selling and servicing our waste oil furnaces for over 20 yrs. We have purchased 3 waste oil furnaces from Waste Oil Doctor. Joe and his crew come every summer and maintain all of our waste oil furnaces. I never worry about not having heat in the cold winters of the UP. If there is any issues Joe takes care of it on the spot. I know when he leaves we are set for another heating season.
