So, I've got this great story, about a guy who bought a house for his sister, yet to be born niece, and himself. It's a long one, and a good one, suffice to say, it's been a long hard road with more bumps in it than I ever could have imagined. Long story short, here's where I'm at...
I didn't know a thing when I bought the place, not even what a floor joist was, turned the heat on for half the month of March with the thermostat down as low as it would go, and the bill was still $260 for half the month! That's when we realized, it has serious issues.
So me and pops started taking a few walls off, revealing the "subtleties" of a house that was built by a diy'er back in 1947 with a few additions here and there. Lets just say we found a few interesting sports pages from the news paper circa 1950s if that gives you an idea of what we found for insulation in the walls. That was one of the first of our discoveries, and the more we took things apart and looked, the more problems we found. Essentially I ended up having to take the house down to the studs of the first floor and left most of the 2nd level floor intact, had to dig up the foundation and fix some things there, modify add beams and beef up the structure and frame up. We framed it over the winter last year, got a roof on it, windows in, and siding on. Since then I've got the plumbing roughed in (did that before the HVAC because there was absolutely no wiggle room for it, 2x6 joists meant everything had to be just right). So now I'm on the HVAC portion, and I've done my best to read as much as possible, attempted a Manual J, have tried to figure out where to place the duct runs and trunks where they make the most sense, and so I loose as little as possible head room in the already low ceiling basement, and try to design the sizing as such as well as I can, but I'm having a really hard time and not doing well with it at all honestly. So, that brings me here, in hope of some sage wisdom and guidance.
Thus far I have bought a used furnace and AC condenser unit. The furnace is an Amana high efficiency 92% pvc venting type. I've installed a concentric kit through the band joist and have it hooked up temporarily without any duct work, but I really don't like firing it because it mainly just heats the crap out of the basement, but that is also keeping the frost at bay down there so it's doing something for now.
Obviously I know that it's going to be nigh impossible for anyone to tell me how to size all of my ducts etc without a lot of information and a floor plan or something to go from. That's not so much what I'm looking for though, although if it's possible, that would be awesome, I have all the data off the top of my head even for square footage of each room, window sizes and U factors, wall R values, and so on. I figured the chances of someone being out there willing to plow through a manual J and D with me were fairly slim.
I've been trying to learn how to do all of this properly, and also how to integrate an HRV system, but again not having a good time of it. I'm also pretty short on money, so buying really expensive college text books or registering for the ACCA and buying their materials probably isn't going to work so well for me. I guess I'm hoping there are resources out there that can actually teach me without having to understand blasted thermodynamics how to size and assemble the plenum and duct work properly and integrate an HRV system.
All constructive input I assure you will be appreciated. Any questions for clarification, ask away. Thank you.
