comment Is transitioning to all electric heating smart?
@HenryJackson. Good point! I hadn't thought about that.

comment Is transitioning to all electric heating smart?
The oil boiler uses electricity for pumps and possibly draft fan and ignition. Most gas furnaces require electricity as well. Electricity outages are not really a good argument against going all-electric.

comment What is the downside to installing faced fiberglass insulation in a dirt floor crawlspace vs non-faced?
@ojait, yes, putting the rigid foam below the fiberglass is a good solution if you really need a vented crawlspace. The foam is a much better vapor retarder than the paper facing. Nice diagrams and discussion of that and other solutions here: buildingscience.com/documents/insights/…

comment What is the downside to installing faced fiberglass insulation in a dirt floor crawlspace vs non-faced?
@DavidC, I'm not talking about a concrete rat pad. I'm talking sealing the vents and insulating the crawlspace walls instead of the crawlspace ceiling. You could use fiberglass, rock wool, rigid foam, or spray foam (in order of increasing cost), but regardless, an unvented crawlspace will be drier and have fewer moisture issues

comment Clickey clackey bathroom exhaust louver
It is one big flap—you can see the bottom of it in the photo. If you want one that has no potential for clickey clackey, try these: conservationmart.com/…. You'd still need some sort of mesh to keep critters out.

comment Getting R38 in roof with 2x8 rafters
Wouldn't the roof dry to the inside? What climate are you in? You may need more than R-10 in foam to keep the vapor retarder (inside face of foam) warm. See: greenbuildingadvisor.com/blogs/dept/musings/…

comment Changing from 2 ton to 2.5 ton AC
"I have to add Freon every 6 months or so." Seriously? This means you have a refrigerant leak and should probably replace the refrigerant lines.

comment What are the pros and cons of sash vs. tilt and turn windows?
Here's an explanation: "Casement and awning windows offer excellent air infiltration performance because pressure from the wind tightens up the seals. Tilt-and-turn windows, with their dual compression seals and multiple locking points around the perimeter offer equal or better performance. Traditional double-hung windows cannot do as well due to their sliding surfaces where compression seals are not possible. And, horizontal sliders generally have the worst air infiltration performance of all window types." from: wascowindows.com/wp-content/uploads/2014/12/…

Yes, there is variation within each window type, but it is generally true. See efficientwindows.org/otypes.php for a discussion of air leakage of different window types.

comment HVAC Duct options in floor joists
So you have an existing HVAC system. Where are the ducts currently? Are you looking to reroute existing ducts serving the main floor, or are you adding on new ductwork for the basement only?

comment HVAC Duct options in floor joists
Is this an existing home or new construction? You would like to avoid soffits, but is there room for a dropped ceiling?
