walked into a mess this afternoon. another company installed a 6 Ton and 2 Ton geothermal heat pump in a dog kennel. they have the 6 ton zoned in 4 different areas ultimately taking care of the kennel side. the 2 ton is for the offices. they are complaining about smell getting into the office areas. They say the have fresh air setup. I go outside and locate the roof penetration where the so called fresh air is coming from to attempt to aid the kennel area from odor. I then go into the attic and find this 16 inch roof penetration is hooked right into the supply duct. exhausting 16 inch round duct of supply air 45 degrees outside right out the roof.
would anyone suggest this so called fresh air set up on the return, or just abandon roof penetration and go with a make up air unit to just constantly circulate outside air in the kennel section.
this was a 32,000 dollar project supposedly and this is what he got.
some of the jacklegs in this area need a butte whooping
