comment How is the Air Conditioning wiring supposed to connect to my furnace?
@melissa edit your post and click the image button, or upload it to an image-hosting service like imgur.com and post the link as a comment.

comment looking for a timer to open and close a circuit
Keywords to find readily-available and easy-to-integrate timers with separate outputs are "dry contact timer" or "pool pump timer". These are available as mechanical and digital timers with all kinds of different features.

comment Can I wire 3 switches to 3 devices through conduit with a single hot and ground?
Small clarification: You still have to follow NEC wire color rules (eg, NEC 200.6) in a conduit. Very basic summary: Grounded (neutral) conductor must be white or gray (or marked), and Equipment grounding conductor must be green or bare (if used), and conversely, those colors can't be used for ungrounded (hot) conductors.

comment Water pressure regulator bad?
Is this a regulator on a city supply, or is it a pressure switch on a well system and/or pressure pump?

comment Need another 240v breaker
The photo I posted is a Murray triplex breaker, available at (at least) one of the huge box chain home improvement stores. The one @kekito linked replaces an existing double pole (so you get two double poles), the one I posted replaces two single poles with two single plus a double pole. Just depends on existing panel layout what makes the most sense.

comment How do I repair a broken polystyrene part?
I don't remember exactly, but I think it broke originally by falling off a TV 4' or so to the ground. The stress of moving around only broke the epoxy repair I did. Good point on reinforcing though. I did come across modelling glue as a good option for polystyrene, but my main worry with it would be the strength on a high-stress connection, which is why I asked here.

comment Can I replace 1 volt lights with 2 volt lights?
I am pretty sure everywhere you've said "volt" you actually mean "watt". Red LEDs typically require at least 1.7 volts, and white require 3 to 3.5 V to even turn on; as far as I can tell 1 volt LEDs do not exist. Most range hoods are hardwired to 120V mains, and the vast majority use 120V standard edison screw-base bulbs (though some may take 12 volt MR16 bi-pin socket bulbs). Please confirm what you have (wattage, voltage, socket, and maybe provide pictures and/or model #s of the existing bulb and hood) and we can answer properly.

comment Can I put an outlet inside of a wall?
@JPhi1618 Because you have to worry about voltage drop. Alarm wire in particular is usually 22 AWG -- after about 15', a 5V source at 1amp will be 4.52V, which is the minimum the USB spec allows for. I know from experience this can have a big effect: with a 10" Tab S connected to a 10' cable and leaving the screen on 24/7, after a few days, it would actually run out of battery. Changing nothing but the cable to a 6' solved this problem. Using off-the-shelf PoE avoids the need for DIY voltage regulator circuitry and/or hacked together cables.

@ThreePhaseEel Sorry, old habits die hard. I really did mean MC (even my picture was MC). Edited.

comment Why is a steel security door safe if they can break the glass, slide their hand in, and unlock the door?
A burglar won't realize this lock is a double-cylinder until they've already broken the window and reached in. At this point, they've already committed a felony, so there's a good chance that they're just going to continue trying. The point is: if you are looking for deterrence, this isn't it. If you are looking for actual safety, this is one step of many that you'd have to take to actually seriously harden your house.

comment How do I fix squishy tiles in shower floor?
You should check around that vent for water damage to the subfloor as well, especially if you can see the floor from below. I'd imagine it's difficult to prevent water from getting into the vent being right beside the shower like that. It may take years, but if the subfloor gets damaged it will eventually loosen the tiles around that too. Shame when contractors/people do stuff like this: it looks great when it's first done, but if it isn't waterproofed underneath, it'll all get destroyed over time.

comment Fix drywall around outlets
@DMoore I guess what I was thinking was about minimizing the seams. I would rather mud and tape a 16" (stud-to-stud) than a 4' or 8' seam from a full sheet. You wouldn't get the advantage of the flat joint (with the recessed edge) from the existing drywall so it would essentially be like a butt joint either way. Obviously if it's close to a door/corner/floor/whatever, just go that distance and avoid a seam entirely. Fewer/shorter seams == good.

comment How to connect garage outlet circuit to power source
NEC requires major appliances (including dryers) to have a dedicated circuit. So if there is (or could be) a dryer on this circuit already, you can't use it for garage circuits. A new circuit on a tandem breaker is the better solution both safety-wise and functionally. A tandem breaker is ten's of dollars.

comment Why is the vent pipe in the basement and not the roof?
No matter what you should cap that off: it's direct entry for sewer gasses (like methane) into the basement. Right next to what looks like a gas water heater. That needs either a cap or to be done properly (P-trap, vent).

comment Connecting a pump to wall socket using a transformer
Note that to meet code (nearly, if not everywhere), any exposed metal on something connected to mains power must be grounded (earthed), to protect people in case the insulation fails. Your pressure switch looks like it has a plastic housing, which is maybe why it doesn't have a ground connection, though there is still a metal fitting for the pressure side. I've never seen one that doesn't have a ground, but so long as it's UL-listed you should be okay. If it is some foreign no-name brand cheapy you're probably safer to just connect it on the low-voltage side.

comment Fix drywall around outlets
I think you could replace stud-to-stud and at least a foot above and below the switch. If it's near an existing seam then might be better just to go right to that seam -- so could very easily end up replacing half a sheet. That said, personally, before I resigned to the fact that I both hate and am bad at drywall (when I still did it myself), I'd probably opt for a combination of mostly "easy" and "half-ass" in this situation.

comment Method to catch multiple mice?
Dealing with the source and food supply of the mice would be more effective. The sooner you do that, the fewer mice you'll have to trap. Just pointing out that while individual traps can be a pain, it should be pretty short-term. There's an average of 6-8 babies per litter, which should give you an idea of how many you should expect to catch. They can also breed between 5 and 10 litters per year, which is why it's important to cut off entrances and food ASAP. :)

comment Water softener beads in the system
Likely not: there wouldn't be enough flow. I added instructions on draining the tank. Sorry, hadn't thought about the hot water tank.

comment Is stainless steel water piping more durable than copper?
What is the water supply? Have you had any testing done on it? If it's a private supply, what type of treatment do you have on it? Curious that only 'one' pipe is having this issue. Is there something specific to that room that could be corroding the pipe?

What makes copper healthy? What makes stainless unhealthy?
