Got to go look at a home that needed something done for air flow. They got their "free" air balance that came with their new home about 2 years ago. Home is about 3 years old now.
H/O had another company recently do a spring maint who mentioned the need for some ductwork repair to fix the airflow issues. They weren't kidding!
So I kind of heard from the homeowner what the deal was and a half hour in the attic confirmed it.
Just think, our new install guys do this stuff in track homes!
So here's the upstairs air handler. Only two runs coming off of the thing. One run has like 7 registers on it. Some over 50 feet of linear flex duct away!
Look at this cluster f**k! (yes, that's all connected together off of one outlet on the plenum!) They come out of the side of the plenum with I think a 14 inch flex. Then it goes into a series of T-Y's all monkey f**ked together! A few 10 inch runs go right to the master beroom, then a 12 inch run goes over about 15 feet and dumps to another t-y then around about another 15 to 20 feet and hits another t-y to dump to another two registers.
To try to solve their airflow problems the warranty depo attempted to do one of the worst air balances I have ever seen. They must have crimped down about 5 different flex ducts with panduit straps to different degrees.
Pretty damn sad. This call was just to LOOK and see what needed to be done. The call was sent in by the builder actually. I told my suprivisor about it and he is going to handle what to do with it so I guess I don't get to go back and fix it myself. I wasn't going to do anything less than unhook it all, re stretch all the runs, and reconnect it properly with proper t-y's and maybe another home run to the plenum and plus the addition of some much needed duct strap!
Those of you from Phoenix know how this is.
