Anyone know about Wood Foundations?

!!!RUN!!!

Here's a little story, semi related

When I was doing HVAC service, I had known that a defunct contractor had built some wood foundation houses around here

One day I got a call from the office, some elderly lady claimed her "ductwork was falling apart."

I went over there, and this house just sort of had "that look." REAL low to the ground. So she invited me in, and here, in the hall (single story) is a downflow furnace in a small closet, so far so good

Se takes me over to a living room supply and pulls the register out of the floor. You can see the ground below!!!

(In "gas school" they told us there was a few of them in the Spokamentro area.....said you can always "tell" because the snow is melted away from the house all around, LOL. That's a joke, son, but they are "about" that bad)

All they did was to build a house with a sealed crawl space, this house did not really even have a crawl.....you could not get under there, the joists were 6" above the ground. Just "throw" a downflow furnace in the house, and pressurize the crawl space. Then just cut a hole LOL wherever you need heat.
