[Greenbuilding] New HVAC unit

[Bob Klahn]

Bobbi,

An after thought; if you get significant rainfall there, you might want 
to go with the blowing fiberglass (they call it "Spider Blown" here) for 
the exterior walls.  I prefer cellulose but if there is a chance of 
water getting into the wall, the cellulose can store a lot, with the 
first warning often being rot of the framing or wood siding.  Under the 
aluminum, that could get extensive before you realized.

You probably can't (don't want to) work with that yourself.  Nasty 
stuff, imho.  In that case, really make sure the contractor gives a 
thoroughly specific contract - and then meets it.

Given the age of the house is would still be a full plaster interior, at 
least in this area.  A good crew should be able to unlock the aluminum 
siding (what's minor damage? You are planning to remove it anyway- 
eventually) but you'll probably have to fight to get them to also lift 
the plank siding rather than drilling and plugging it.  Who wants to 
spend that kind of money on a polka-dotted house??

A good crew can drill and tube through the interior wall and patch their 
holes invisibly.  On an old hose the baseboard may be tall enough to 
hide the holes, if it's pulled and restored.

Sorry, now it's insomnia...
