For pure cooling stand point, samsung has much higher cooling output than kenwood or pel.
for long term durability and after sales services, Acson and Mitsubishi are one of the best.
Gree is an all rounder ac with decent price, very good cooling, and a very long hitorical track record… they work in 48Cwhen every other brand fails.
LG is way too over priced… Art cool sucks D on price alone,
In local Dawlance, Pel and Orient are ok… orient older modles were good, but they lost the ball after the DWP group split, and their capillaries often leak without reason… our old orient is fine, our plasma fin orient leaked after 2nd month.
now days Changhongruba is ofering ac in dirt cheap prices, which even if they last over 3 4 years makes up for their prices very easily.
kenwood ac should be bought by those with Bank alfalah cardswhere 0% interest 6 months installments make them seem a good affordable option.
PS: as long as your Haier ac is in warranty, you have nothing to worry about as their warranty service is good. but after that, their parts are very expensive as there is only OEM no aftermarket for them…as long as Haier is working, its very good.
