Good tint has high IRR and TSER. 3M stuff should be good, I use 3M for front windscreen only and it already cut alot of heat for the car. Rest untinted.
Darkness (visible light) transmission is not a good criteria to compare tints. Most of the heat still come in on IR which is invisible wavelength.
For your hall, best to measure the width x length in feet with measuring tape and draw out the shape in ms paint for more accurate sizing.
Because house layouts can vary, and so does the living hall..some more bedroom and small living..some no GF bedroom and long living hall.. or living room is big and have small offset for dining area.. too many possibilities. But if developer already built in the 1.3hp pipes then it may not be excessively big room.
Do you think a blind that blocks out light good enough to replace tint effect?
Actually the hall (need to verify) I believe they have the bigger pipes meant for 2hp. But I really don't stay in hall that long and just for dinner only. Maybe occasional guests. So I guess 2 1.5Hp should do the job. I will get the aircon guy to go see and give me recommendation.
As for the half past 6 dealer, actually it is very reputable one. But I am lazy to write again the full details, let it be. I will be buying several Panasonic 1.5hp inverter first, the rest most likely Mitsubishi non-inverter 1.5hp and 1hp. Still thinking if buy now to lock in the price or risks further price increase after 3 months (renovation period).
