JD Heating replaced my oil tank two weeks ago with a 275 gallon Roth tank. Leon was very professional, explained the work involving the install process and is very reliable. His pricing was very fair and the quality of work was excellent.
I cannot say enough great things about JD Heating! They came to my rescue on such short notice when I had a heating issue in my new home in the Newtown area. Leon, my technician, was amazing—extremely knowledgeable and personable, making the entire process smooth and stress-free. Their prompt response and reliable service have earned them our trust as lifelong clients. I highly recommend JD Heating to family, friends, and especially to anyone in the Newtown neighborhood looking for honest and fairly priced heating solutions. Thank you so much for fixing my issue quickly and efficiently!
