Purchased two haier 1.5 tons and two haier 1 tons inverter ACs (cool only models) last year at the end of the season. The model numbers were 18 LEK 03 R2 and 12 LEK 03 R2. These are imported models launched by haier for sales promotion in 2013. The 1.5 tons ACs have been extensively used this summer. Both the 1.5 tons are installed on the first floor. During the continous heat wave of second and thrid week of june when temperatures remained at 45 degrees, the ACs performed flawlessly as far as cooling is concerened. The room sizes are 18 feet x 14 feet, but the roof is insulated with 6 inches of jumbolon board and and outer walls with one inch jumbolon board. Therefore the room temperature on the first floor never exceeded above 33 degrees without air-conditioning. When the AC was switched on, it brought the room temperature down to the set temperature of 26 degrees within 45 minutes. During the one hour load-shedding period, the room temperature remained below 30 degrees which was quite acceptable and no one in the family complained of any discomfort. As far as power consumption is concerened, it fluctuates between 3.7 amperes to 8.5 amperes. However, on average during a 24 hours period, one 1.5 tons inverter ac consumes 1.01 killowats per hour, which turns out to be an average of 4.54 amperes (at 230 volts) for a 10 to 12 hours operation including the start /stop cycle due to load shedding. The verbally claimed power consumption by haier agent in DHA was 4.9 amps for the 1.5 tonns ac. These days , I am running only one inverter air-conditioner and total units consumption for the month of june this year (from 1 june to 26 june ) have been 590 units so far. This comes to an average of 22.7 units per day for an entire 1 kanal house including two refrigerators, two LED Tvs and other home appliances like clothes iron and microwaves. I would say that the combination of insulation and inverter based air-conditioners have reduced the power consumption by more than 50 percent, as my last year june power consumption in the previous unisulated house with a conventional 1.5 tons air-conditioner was 1260 units. The bad news is that only yesterday I went to the haier agent in DHA lahore once again to buy another inverter ac and they informed me that the import models are now finsihed and they have now only the locally manufactured units which consume an avarage of 7.7 amperes current. On hearing that, I decided to search for the imported unit from thailand in abid market as there is no point in buying an inverter ac for Rs 75,000 which consumes only one ampere less than the conventional ac. By the way, I havent experimented with the two 1 tons haier inverter ACs yet therfore I wont be commenting on them but I beleive that they should perform fine as they are installed on the ground floor where temperature conditions are even better. As a closing comment, if you are out in the market for a haier inverter air conditioner, look only for the imported model from thailand as dealers might still have them in stock. I paid Rs 80000 for the 1.5 ton and Rs 70,000 for the 1 ton model in october 2013 as the season had run out. I hope this satisfies most of the posters.
