It's quite easy to check that something is at a particular angle. Just put the appropriately sized block on your level at the appropriate distance, and make your level (with the block) level. Your off-level surface makes a right triangle with respect to an imaginary (or provided by your level) level surface. The level is the "adjacent" side of the angle, ...

It's much easier to check that something is level than to check that something is 6 degrees or 1/4 inch higher. Build it level. Then add a 1/4 inch strip of wood (a length of lath or trim) across the inside edge of the horizontal framing member. You are correct that the sleeve will be sitting on two edges, the added trim strip and the outside edge of the ...

3-phase is slightly more efficient, but not nearly that much for units like this. 3 ton is a very small unit for central air. It is HIGHLY doubtful you (or a tenant) will see any noticeable difference in their bills. Considering the dramatic difference in cost ($700 less), it's a no-brainer to go with the single phase units.

Q1: The coil can get plugged with contaminants. Maybe if it was improperly filled, or water got in through a leak. Both situations tend to be rare. Q2: I'm sure diagnostic equipment exists, but most techs would either just flush it or pull new copper line.

I don't know what it does in terms of which part of the spectrum it blocks (IR or not?). It has done a fantastic job. It colors the view just a bit, though you only really ...

Im not sure what building codes or home owner's restrictions there may be but this is a common solution: There are many types of variations that are tied to houses, stand alone, etc. It is basically a set of posts (or house attachments) with a top plate and vertical boards (pressure treated of course) affixed. This example then has cross bracing so there ...

When in Bangalore, we used to live on the top floor of a 13-storey building and there aren't (m)any trees that reach up that high to block the sun. Your option 1 won't work optimally, simply because the sun moves around too much, and unless you have some mechanism / person moving the cloth around to make sure your entire terrace is in shadow, you'll never ...

You essentially need to stop the sun from hitting the terrace surface by any means possible. A shade structure of some type. Plants help too because they transpire moisture, cooling the air. But if they overly restrict airflow the cooling effect is offset by lack of circulation.

If Option 2 won't be approved and Option 1 will, go with Option 1. It should work.
