Forced Air Central Heating is AWESOME

Well, after several weeks of tinkering with it ourselves, I finally got the DH on board with calling a certified repairman to work on the furnace. 
Liquid Propane is not a gas to be trifled with, if you didn't know.  Being heavier than air, a gas leak can fill a basement with fumes.  From that point, the ignition of the furnace or a water heater, or any number of other things can cause a catastrophic explosion.  The only upside to such an explosion is that it usually "blows itself out", whatever that means in "Volunteer Fire-ese". 
Now, How?, you might be asking, does this apply Beige Recyclables?  Well, in researching the furnace online while we were trouble shooting to find out what its problem was, I discovered that the poor little furnace is actually a Mobile Home furnace.  Oddly enough, made by Coleman, the camping people.  And, yet, somehow it made it's way into the quasi-basement, glorified crawl space of a 1911 Four Square Craftsman farmhouse with about 2500 sf of living space.  Hmmm, I'm thinking my Engineering friends would go pale if asked to do the calculations on that heating load.  So, it's probably a miracle that it has kept us this warm for this long.
And, I am so glad that the repair-guy could find a part to repair it at all, and really thankful that the whole saga added up to a little under $1000 when all was added up.  It could have been so much more.
So, we'll be taking as much advantage of those Insulation Tax Credits as possible.
