So sold a G100 to a guy to replace his 16-17 year old Woodmaster, no problems there, he sold his old Woodmaster to a kid for a $1000 bucks. I’ve talked to the guy numerous times, been by his house and seen all of his vehicles, everything is meticulously maintained. Only issue I seen with the Woodmaster is needs a new door seal.
So, my uncle happened to be at the guys house that bought the Woodmaster, they had talked to me before about hooking it up. Phil was replacing the septic line from the house to the tank as it was orange burg pipe and was clogged with tree roots.
Soon as I pulled in regretted to dealing with this, house has the old thick fieldstone basement walls, one wall in the basement has been replaced with block from tree roots pushing on it, that is inaccessible as it has porch on the outside. Ground is so hard and dry Phil was about standing the mini on it’s nose trying to dig, so no way am I hand digging under the porch to run the pipe. Only other accessible wall is thru the crawl space of course. So looks like I’ll be breaking the new diamond coring bit out for this one.
Now for the real issue, basement is low, real low, even with only reaching the standard Lappin height of 5’9” I still whacked my head a few times on the floor joists. They just had room to get the A coil in above the furnace, then to top it off looks like they connected the A coil then ran the return duct as there is exactly zero room to work. The guy I’ve been talking to has several rental homes as well and their HVAC guy already has em dead set against a HX in the return, and the way thats set up won’t be easy either unless I literally mount it in the furnace cabinet.
So back to doing several smaller HX’s in the trunk lines, except even those are a cluster f*ck. One 8x18 trunk heading east, one 8”x8” heading north then three 6” rounds heading west and south. The three rounds are attached directly to the main that houses the A coil. Actually found a 8”x8”, so thats not an issue. No such thing as a 8”x18”. So will have to cut the duct out on two sides, fit a 12x18 then blank in around whats not in the duct. For the 3 rounds I figure to build another 8x18 trunk line, get it the required distance from the A coil then hook the rounds back in and blank another 12”x18” HX in so both large trunks are the same.
Now for the fun part, figured to use a mono flo T to split off to the large HX’s. After that I’m not sure whether to bring both returns back together, then use another mono flo T to feed the 8”x8” HX. The other thing I figured to do first is to see how many 6” rounds come off the 8x18 trunk, if it’s more then I might just take the return from the HX feeding the three 6” ducts and run that to the 8x8 HX since it won’t have the airflow thru it that the other has.
My sense of direction didn’t fail me though. Owner of the place wasn’t even sure what wall we were looking at once in the basement. I knew even in a strange basement where north was. I told him think about it this way, we came in the side door, walked thru the living room, turned right into the kitchen, turned right into the hallway, turned right to the basement stairs, turned right again once in the basement, so there for we were facing the same direction we started.
