Should not be voltage issue. I installed those lights+fan from TB, only complain from installer is the hook need to modify.

btw, did you 5) Extend 7 feet master bedroom? Can you show some pics?

And please do update us on final reno cost.

Hi, wanna ask, how do you conceal aircond piping? Have to drill the wall? Sorry, noob here.

You see the original design of the backdoor is oepning inward, there is a reason for that, its for security concern.

Your new backyard door open outwards, which means the hinges are exposed to the outside, burglar can just remove the hinge and your door will come right off...

AC compressors should be on mounting blocks raised from the floor like thus as shown in the last picture.

Hmm, i guess to keep cost low the beam has to stay. It is a structural beam to hold the house, not easy to remove/replace.
Just dont place your  bed under it, bad fengshui

Mainly that and to alleviate from heat stress by avoidance of conduction of excessive heat from the ground.

Same thing. Its always recommended to place the compressor on the riser. The riser should have anti vibration pads as shown in the link given.

Also one more thing, the compressors are placed too close to the wall on its left side for the one the bottom pic I quoted. Its needs space to "breathe" to prevent premature compressor failure due to heat stress. Although York's manual online doesn't show it (but floor support aka risers are shown), Acson's manual does as seen on page 4. Many others will show as does mine too in the manual (pg 35).

Come to think of it, the wall mounted Daikin compressors too. They  are too close under the roof eaves. Usually, I would leave at least 8"-12" clearance from under the eaves.
