comment Should a 12V DC dimmer switch produce 24V AC on the output?
I'm confused about what you're measuring, e.g. how can the output product both DC and AC? But if your "dimmer switch" is taking DC as an input and outputting AC than it's really an inverter, not a dimmer. I'm not sure you have the right pieces for a DC lighting setup.

comment Is it possible that my GFCI receptacle is bad?
Note that you can have multiple GFCIs on a circuit without having them be "in series", as bib calls it. There's not enough information in the question to know how the wiring is done.

comment Staining already stained wood
There are no shortcuts in sanding. If you skip around with the grits too much you will just create more work for yourself. Pick the right grit for the level of removal you need, then work your way up until the surface is as smooth as you want.

comment Cleaning a very dusty garage
I always use the filters and have never thought much of it. Periodically I'll clean the filter by putting it in a garbage bag and banging it on the ground to release debris. I replace the filter once a year or so on general principal, although I can't say I've ever noticed much of a difference in suction.

comment Extremely long dryer vent line, non efficient dryer
I think it's likely the run is too long or obstructed. In addition to being a nuisance, an improperly-vented dryer is a serious fire hazard. @JimmyFix-it's answer below has a link to a very helpful chart. You will need to figure out exactly how long the vent is, how many bends it has, and what it's made of.

comment How much concrete is required to hold 125 lbs/sqft permanently?
@Sophit: If the soil is so poor that the entire floor is sinking, you may have to deal with that first. Even a 1' thick concrete slab will sink if the soil can't support the weight.

comment Undersized AC - Options?
It's a little late now, but the "ton" rating is how much heat the units can remove from the air. 5 tons is 5 tons, there's no modification for "efficiency". A new, efficient 5 ton unit might use less electricity than an old 5 ton one, but they should cool the same.

comment Why did polyurethane make wood feel coarse?
I usually use a foam brush, with good results. The trick with foam brushes is to not squeeze them—just dip them in the can and then dangle to drip off a little, don't drag them across the can edge. That's a sure way to introduce air bubbles.

comment Truss Spacing and Sheathing Type
Determining the load-bearing capacity is the job of the engineer. Presumably he would not have offered an option with 24" spacing if it was unsuitable.

comment Truss Spacing and Sheathing Type
Why did the engineer give you 3 options? You might ask him/her if there are other cost ramifications besides just the trusses. I would think the engineer should give you the single most efficient design that meets your needs, there shouldn't really be any choice about snow loads or weight-bearing ability.

comment Insulation options for narrow ceiling space
@wallyk: Nope, R value is a ratio but it's not unitless: it's the ratio of how much energy gets through a certain amount of area based on the temperature difference, in the US the units are ft2-°F-hr/BTU (and units for U value are the inverse).

comment My electric oven runs 200C too hot. What can I do?
How are you measuring the temperature? Cheap bimetallic oven thermometers can be very inaccurate.

comment Help connecting cat5e cables for home networking
@Tester101: you might be right, although without looking at the markings on the side of the cable it's really hard to tell. CAT 3 can have 2, 3, or 4 pairs. "CAT 5" and "CAT 5e" are often used interchangeably to mean CAT 5e, but some old buildings do have real CAT 5, which is not capable of gigabit ethernet.

comment Why does my GFCI receptacle trip when anything is plugged in?
@user23728: If the GFCI trips when sometime is plugged directly into it, then I would start by disconnecting everything downstream. Then test is. Then reconnect just one outlet, etc.
