More like no duct design... Hi Guys-Quick back ground of what I'm dealing with:
Purchased an older home with a new addition almost 2 years ago. The original home is early 1900s while the addition is 5 years old. During the addition, a new high efficiency furnace was installed and the installers modified the existing duct "work". Here are my issues:
1-Return in Kitchen
2-Returns in completely packed closets
1-Return in laundry/slop sink room
1-6"x12" Return in dining room
1-6"x12" Return in master bedroom
1-4"x24" Return in new addition (which is a closeable diffuser type)
1- 6"x 12" Return in new addition upstairs
Some how the 4"x24" (96 sq in) RA is supposed to provide enough air to the 5-4"x15" (300 sq in) diffusers in the surrounding area. The other supplies in the home have ducting that are exposed to the attic air (I live in WI BTW) or are placed away from windows and cool spots. A majority of those RAs use the outside wall stud spaces as the duct work, which aren't even close to being sealed and they have both high and low voltage wiring running parallel and perpendicular in them. Even more mind boggling is the lower portion of the new addition has no RA/SA ducts to it so in summer we have mildew growing on our furniture (yes i started dehumidifying down there).
4/6 RAs are out of code in more than 1 way. They are not modifiable because of the old wall make ups without major renovation involving a ton of lead containing debris. Nor is there enough of them to supply the SAs with air without taking air in of the wall cavities.
5/12 SAs are in terrible spots or exposed to unconditioned space.
Even my thermostat is in the south room with the most windows.
I'm angry that "heating professionals" such as these still function and get good reviews even through all of their stupidity. Luckily I am a solar installer/designer and have a decent handle on hydronics/new ducting.
My end all question is: Should I just abandon the heating system, sell the furnace, install low temp hydronics, and go with whole home controlled ventilation? I'd much rather. Piping is much easier to balance and install in a home such as this.
PS no flack for not seeing this before purchasing the home. Every home in this local/price range either has this kind of poor duct design/remodeling or had a 1920 steam boiler with 4000 lbs of asbestos wrapped pipes.
