I was not satisfied with the quality of workmanship with the new ducting for several reasons. 1. The ducts coming out of the plenum were squished against one another, choking off air flow. 2. The straps from which the ducts hung cut deeply into the ducts, significantly cutting off air flow. 3. The ducts did not travel directly from the plenum to the outlets but bowed significantly with excessive slack. 4. The ducts were not sealed to the plenum. I called the office manager, Tommy, to express my dissatisfaction with the workmanship. He sent installers out to reinspect it (while taking many photos). Both the installers and Tommy assured me the ducts were installed correctly. I knew that I was not getting air flow from all my ducts but I did not know why. I contracted with an insulation company to reinsulate my attic. After inspecting my attic, they informed me that, in addition to my above concerns being valid, the ducts had not been installed correctly. Instead of connecting from the plenum to a Y intersection where it would branch out to two outlets, a large diameter duct connected directly from the plenum to one outlet with a smaller diameter duct branching off backwards from that larger duct to a second outlet, which explained why I was getting tremendous air flow from some outlets and none from others. The ducting was arranged this way twice, affecting four outlets. The insulation contractor informed me that whoever installed my ducts did not know what they were doing and that it had to be fixed before they could reinsulate my attic. When I explained that One Hour manager, Tommy, viewed his installer's photos and insisted that the ducts were installed correctly, he offered to speak to Tommy in person. After meeting with Tommy, Tommy stated to him that he would call me to schedule a time to fix the problems. I waited over a month to hear from Tommy without hearing from him. I finally called him and scheduled a time for the installers to redo the ductwork. The lead installer who came out told me he was embarrassed by the work the original installers had done and that they were no longer with the company. He reworked the ducts to address my concerns but he refused to seal the ducts to the outlets because he said that was existing work. Maybe so but that metal to metal still leaks air and it would have gone a long way to show that One Hour wanted to do everything it could to make it up to a customer after delivering such shoddy work. I had to pay the insulation company to seal the ducts to the outlets. What really bothers me is that both the installers and the manager, Tommy, repeatedly insisted that the work done was properly performed and correct. It was only after another professional addressed Tommy face to face with photos of the deficient craftsmanship that he acknowledged it. Then, after waiting more that a reasonable length of time for the One Hour manager to call me, I had to call him to force correction of the deficient workmanship. In addition to this, when a One Hour inspector came by for the winter inspection, he informed me that something to do with the heating vents (or pipes?) were too small. This was One Hour's own man telling me this but, of course, Tommy insisted that they were within code. Another thing - during the worst of a cold spell our brand new One Hour furnace broke down leaving us without ANY heat overnight when temperatures dropped to below zero. A brand new heater breaking down when you need it most!? This is quality? I have totally lost faith in One Hour management to be honest and to deliver quality workmanship without being forced. I would never recommend One Hour to anyone. I regret ever having done business with One Hour.
