I understand, I'm just pointing out drawbacks others might find. Different buildings, ya know? Changing the balance of the system is what keeps everybody fighting. When you do that, you change the air flow to all the branches on your leg of the system. The guy in the next room is trying to figure out what went wacko so he blocks off part of his registers because now they are blowing twice as hard. Paperwork is leaving the desk on it's own. They have adjustments on all the ducts and they are in the ceiling. They don't let just anyone mess with them. That's why they don't put adjustable registers on. Be sneaky and re balance the system. The next air guy out ther will think the last guy did it even if he notices anything. They changed the heating ducts at the ski resort and the guy with the locker that got heat, didn't have it anymore. I said some thing about tapping into the ducts in the ceiling and he got Joe, our union tinknocker friend, (Joe is FAST), to put a duct in. The dummies put a 6 inch line in probably because that's all Joe had laying around and didn't throttle it enough. I guess the guy whose office got cold complained. Caught!!! Do what you want Fred but get the building guys to help you, under the table. wink, wink, nod, nod KR On Thu, Jan 13, 2011 at 10:24 AM, Fred Sturm <fssturm at unm.edu> wrote: > On Jan 13, 2011, at 10:44 AM, Keith Roberts wrote: > > Cutting off the return air is probably the fastest way to create a >> heating/air system that needs the repairman to be there for big $$$$ and >> will shorten the life of the system costing replacement bucks.
