Yeah I don't think the person you're replying to has any experience in building control systems. I used to be an energy engineer and I would predict sub-floor

  The point does stand generally though. I have had to replace entire HVACs because the coolant is no longer available or because the cost to replace a certain component is too high because the parts are no longer readily available. I think the only solution is to try to build as minimally as possible. A huge amount can be accomplished through passive heating and cooling (windows placement and size, site location and angle toward prevailing winds and morning / afternoon sun, etc etc). We are too often reliant on technology to allow us to ignore these things and we do so at our peril.

  >experience in building control systems lol. If you mean 'design', you'd be surprised. Admittedly, I'm not aware of the full array of residential heating control systems, but I've sure seen some over-complex ones.
