Jul, contractor for Ductworks, called on his way to the home, was very prompt, courteous, and engaging. He checked and double-checked the home for vent count to make sure the price quote was correct, and he did not try to pitch sale additional services without me asking first. Jul worked very hard for almost 7 hours to do a great job, multiple times stopping his work to explain progress. Cleanind ducts is not inexpensive, but it's worth the money to hire a company like Ductworks and a contractor like Jul that do the work properly. We were pleased with our choice and would recommend this company.
