comment Can I vent a portable air conditioner inside?
According to thermodynamics, the room will heat up by the amount of electrical energy dissipated as heat by the air conditioning unit. So while you will have cold air blowing on you, it will progressively get warmer as the rest of the room heats up. "There's No Such Thing As A Free Lunch - TNSTAFL"

comment Framing a window directly through a post in post-and-beam construction?
You're removing a vertical support from the structure. What are the proposed jack studs sitting on that will reliably transfer the beam load into other vertical support posts? The wall framing is not a support structure in this construction and if those jack studs are merely planted on the floor plate without a post beneath where each side contacts it, you're merely creating a cosmetic application that gives a facsimile of framed construction support without the support. Looks pretty...

comment water flow difference between 1/4 turn and multi turn shut off valve
Port size needs to equal pipe ID size. I've seen what essentially is a 1/2" id port on a 3/4" pipe valve. Throw it at the store's purchasing agent, being sure to leave a dent. The worst are the ball valves you get for use with garden hose. The ball valve port may be only 3/8" on a 5/8" hose, stinks if you're on gravity feed irrigation.

comment Why are GFCI systems typically in the receptacle instead of in the breaker?
In the US at least, GFCI started out as a retrofit, easiest done in the outlet box specific to the need. I've seen a 20A breaker service two bedrooms and a bathroom. The house before that was fused, can still use GFCI outlets.

Dent means the hammer is moving, but something's blocking the nail from feeding into position.

comment Can I convert a 240V dryer to 120V?
The heating element will barely glow, unless your dryer actually is dual voltage with a split element and jumpers for the voltage switch. Half the voltage, twice the current then.

comment 3/4 slip to male fitting does not match garden hose outlet
Garden hose outlet (what the hose attaches to) is 3/4 MHT (non-tapered thread). Not sure how the question matches the description, but 3/4 NPT (tapered thread) will not work with 3/4 MHT/FHT (straight hose fitting thread)

comment We have used Filter sand for construction , Is there a problem in this sand?
Sharp sand, completely washed of all organic content. Anything else and you have weak concrete. If you didn't spec it before the concrete mix, you just have to accept the consequences, except in countries with building standards, at which point you will be getting in equipment to rip out everything where the substandard concrete pour happened. Try being the idiot contractor that did this to Walmart locally, one less concrete company in the area as remediation bankrupted them.

comment Do I need to level the outdoor AC cooling unit?
The wood or plastic would be fine, the bottom of the outdoor unit is a pressed metal frame that the shock mounts attach to. Leveling the base is all that's necessary. If you're worried about contact area, just use a wider wedge. The shock mounts isolate the hermetically sealed compressor unit from the base for noise reduction and absorbing the startup kick.

comment Will KILZ® contain black mold?
From their product description: KILZ MAX Clear contains a mildewcide that helps protect against growth of mold on the primer and is not intended to provide mildew protection on the substrate. => Mold or Mildew Covered Surfaces: KILZ MAX Clear should not be applied to a surface containing mold or mildew; it should not be used to cover up mold or mildew. Wash the area with a mildew remover, rinse with water and allow to completely dry before coating.
