I am beyond pleased with the work Scott McDowell did on our furnace. He was honest, super happy to answer questions, and quick and efficient. And with tight funds here, he worked out a fantastic price for what we required. I’ve gone through RSJ before, and I absolutely would choose them first again, if necessary.

Our basement needed duct added to rooms that in initial build were not done. RSJ did a great job extending and adding duct where needed allowing for basement to be finished, and to get a more evenly distributed flow of air though our basement.

Scott was amazing. So kind and considerate. Fixed my tricky problem with ease. My old home
Boiler heat was giving me problems but he figured it out. I appreciated him and I’ll be having him out again if the time comes! Highly recommend this company and Scott!
