Unsure about energy audit suggestions...
I apologize in advance for any length and confusion.
I'll describe the house:
Location is Mid-Hudson Valley NY.
2 story colonial (I moved in about 2004). I think it had been built for someone else in 2003. Appx. 2300 sqft.
Attached 2-car garage, bonus room over garage, unfinished basement.
Central hydro air (oil boiler, indirect tank, air handler in basement & attic).
2006, an addition was built off of garage, resulting in a house that is now "L" shaped.
Being foolishly dumb, when the addition was added, I senselessly stood by as the contracted added yet another air handler system in the (unconditioned) bonus room along with another condenser? outside next to the other 2 units.
Anyway, after hemorraging oil these last few years, I got one of those NYSERDA audits. Here is some of what was recommended...
1. Attic air handler having issues - appx. $1300 diagnose & fix.
2. Replace unit ($6500 plus?)
3. Bigger oil boiler & 1" pipes.
4. Seal, blow cellulose in attic, also spray attic rim joists, add door to concrete stair leading out to bilco door.
I said, hold on! I think I better do some research first. And so I found this site and did some reading.
Oh, and the way the addition was built, part of it has a flat ceiling, the other half a cathedral type ceiling. With recessed lights no less.
I got another attic quote from a contractor who recommended open cell spray in the attic (about 7.5", 3.5" on the attic wall, about the same in bonus room and spray the bonus room floor).
1. There was no mention of spraying the rafters. Should I be concerned about that?
Also, they said they typically cut out the sheetrock from the garage and spray. Why would that be if the bonus room is unfinished? (I can move all my junk out of the room).
2. I asked what about the addition?
He said they could spray the half that they can get access to.
Does that seem sensible? Anyway, after hearing the price, I'm thinking I won't be able to get all that done anyway.
3. In between the attic and the bonus room, there is a sort of crawl space where you can crawl through and jump right down into the bonus room.
The guy said they would seal off (leave it partitioned off) that space such that the attic & bonus room would be separate.
That would leave a unvented attic, a vented space about 6 feet long, an unvented bonus room.
Does that seem reasonable?
