i have Dawlance inspire plus 30 1.5 ton heat and cool. used 2 summers. in another room orient 1.5 inverter.both the great performance.
both are top floor rooms.
kept at 30C and used full AC speed and full room fan it gave 28 in the room. (my nature is to keep myself comfortable not uncomfortable cooling, i am ok with ceiling fan usage )
if keep it at 28 it bring to 27-26C overall.
Performance: with 30C full fan speed and full ceiling fan it always gave me 1-6A in the start and 3A after saturation during day time and 1.5A during night time. orient had the same performance bcz it has the same AC unit inside bcz both have same generic booklets.
i will buy daikin mitsubishi (1 lakh ka) gree (70000) or dawance (52000) rest all have minor better performance benefits at large money diff.
if there is loadshedding like after every 1hr then inverters are useless.
Ceiling Fan at min speed use is MUST if living at top floor bcz all heat layer remains top of room which confuses the AC thermostat and keep AC compressor on to attain temp. so use ceiling fan to mix tht top layer of room heat.
