Hello everybody,
Though I have been using the services of Mouthshut for about 2 years, this is my first review about a product. I purchased an O General 1.5 ton window AC (AXZ 18) last week, after having reviewed many established brands in the market. After my first round of review, I was planning to buy a LG machine, primarily for the following reasons.
a. Relatively low prized
b. Modern look
c. No.1 in terms of quantity of sales
But after my second round, I decided to switch over to O General. The features of OG made me to change my decision though the prize is a bit high as compared to other machines. But it is worth it. In fact every dealer told me that in terms of quality OG is the number one irrespective of whether the dealer sells OG or not. Indeed, after having purchased it, I am completely satisfied with this product.
Main features:
Its power in British thermal unit (BTU) is 19800, way higher than all other brands. (Usually 18000 BTU is considered as 1.5 ton – hence, OG gives more cooling). It is air circulation in high mode (measured in cubic feet per minute) is 547 which is again way ahead than other machines. (A LG 1.5 ton machine’s air throw is between 470 – 500 CFM) and its moisture removal rate is as good as any other brand in the market. More than that it consumes less power and gives you more cooling. The energy efficiency ratio (EER) is 10.58 for a rotary compressor and 9.90 for the reciprocatory compressor. (EER is calculated as Cooling Capacity (BTU/Hr.) /Power consumption (Watts/Hr.)) Again all other brands can offer between 9.0 to 9.75 EER, OG saves your money in terms of EB charges in the long run.
Above all the features, one thing which made my decision to swing over to OG was its low deration factor. It is measured as the temperature in the X axis and the cooling efficiency in the Y axis. If there is no deration, the cooling efficiency is constant even the mercury touches 45o C. Most of the machines in the market have high deration factor, i.e. as the temperature raises the cooling efficiency drops. It is because of this with other brands of machines we feel the cooling efficiency in summer is not that high as it used to be in winter. Hence, OG is the top selling brand in Middle East where the mercury touches 500C often.
Besides that OG machines are sturdy that they can withstand the extremes of temperature. Its front and rear side fins are so strong. But the fins are very thin with most of the other brands.
Most of the brands have a lot of models, (LG has about 20 models) even their dealers don’t know which models they sell. But OG has very few models and hence, you always get the spare parts whenever you are in need of them. (The OG Dealer told me you will never need them for another 10-15 yrs) In fact they have not changed its design for so many years. One reviewer cited this as a bad feature in OG, but I strongly recommend OG if you are quality conscious.
