the pipes instead of going outside from behind the indoor unit, will come out from the sides. A small piece of plastic in the indoor unit will need to be removed. There is provision to do the same in the indoor units. I have a similar setup in my house. | |

Call me silly if you will but I have all the windows open all the time which are mosquito net proofed though. There are 5 windows in all and each window being 10 square feet. It does not cool down to chill levels but keeps us comfortable whether during the day or night. Temperature in Kerala never crosses 37 degrees where I live. Those living in hotter climates will not have the luxury of getting fresh air. I do not expect my AC to cool below 26 degrees too. | |

Routing the pipes through the skylight will make it difficult for you to deal with the gaps around. Instead take the tried and tested method of using a concrete drill bit and making a clean hole rather than obe made by hammer and chisel. The pipes can simply pass through from behind the machine instead of the sides. Any reason why you do not want to drill a hole in the wall? Quote:

I haven't used the AC much so can't really comment on the performance, but initial impression are good. | |

Infractions: 0/3 (13) | ![]() samsung I ve found is first class. excellent after sales service too. a 1 tonner with 3 star rating, including stablizer and installation free, costs a total of about 23500/- in Bangalore. A good price in my opinion. |

| ![]() I have been using General 1.5 t window ACs since 2004. One was bought in 2004 and the other in 2005. The 2004 one was sold in 2011 after 7 seasons of usage with it giving no problems at all. No gas leakages, no thermostat failures or anything at all. The 2005 one is still going strong in its 7th year. Last week, I replaced the 2004 General AC with a 2 t General window. The older one was sold to a person who had bought a Samsung in 2008, which was nearing end of life in 2010 itself. Could be a defective piece or a cheaper version (he bought it for 18K in 2008). For window AC, I am sticking with General for as long as it maintains the same or even somewhat lesser standard. The cost is higher but it pays more through better cooling, longer life, lesser maintenance (only service), and better resales. I have been using window ACs since 1997 and except for General, none of them could last beyond 3-4 years. Of course they could have lasted longer with substantial repair costs. |

Team-BHP Support ![]() ![]() | ![]() @spyking. I forgot to add. There are three pipes that exit in the indoor unit. 2 of them carry the refrigerant gas. One of them drains the condensed water. Take special care of the drain pipe. It should go down straight without any upturns. That will cause a water block and eventually mildew formation. It can happen with just a day or two of usage and is characterized by a foul smell. |

We had 3 Window ACs in three bedrooms in Goa in 2002/03. High humidity and high ambient temperatures is a norm where I stay. The coastline is about 200 meters from our house. We got 2 Generals and one LG. And all three are working great. Actually exceptionally well. Touch wood. The LG keeps up with the Generals quite well. My dad strictly follows the service schedule and maintains a log of all repairs done. Presently the log of repairs for all three is blank. So I guess not taking anything away from the mercedes and bmws of the ACs, the maruti's too keep up with the hallowed/costly brands quite well. | |

1. 1 ton for every 1000 cubic feet, or in case of modern flats 1000/9 = 111 square feet 2. 1 ton for every 5 persons in the room 3. 1 ton for every 3kw of appliances in the room. Hence if you have a 12x15=180 square foot room, with two persons and 500w of appliances (fan, TV, stereo etc) the tonnage required is 180/111 + 1*2/4 + 1*500/3000 = 1.62 + 0.4 + 0.16 = 2.28 This tonnage would cool the room in a temparature differential of 20 degrees (42 - 22 degrees) if you can bear minimum of 25 then the tonnage comes to around 2. If day temperatures hit 45, then the tonnage may go upto 2.5. This is of course the peak cooling requirement mainly during day time. At night the temperatures hover around 36 and smaller unit would suffice. NOTE 1. Most of the calculations on the net, ignore the fact that we in India have AC in one room, and the passages are not cooled, hence a lot of cold air leaks out. Every time you open the door (even to the attached toilet), you loose cold air. So you should have at least 15% over capacity. 2. One method of reducing the cooling requirement is to set the AC at 25 and run the fan on at slow/medium speed. 3. If the summer is exceedingly hot and dry, you can increase cooling by regularly spraying water on the rear heat exchanger. This increase the thermal efficiency by cooling the hot-end. I remember AC 20 years ago used to have a water tank with a pipe dripping water for this reason. | |

| ![]() Which of the 2 brands are better among 1.5 ton split 5 star AC between Daikin and Hitachi? I am looking at models presently available here. It would also be of tremendous help to me if I can get the indicative price for the above two brands. Daikin was quoted at 41k all inclusive and LG at 36k at Reliance Digital. Also, is it advisable to go in for the ones with inverter technology or is it merely a not so important feature? I am more keen on R410 refridgerant as compared to R22 in view of being future proof. |

| ![]() Can anyone tell me if Hitachi is a brand worth buying (Window AC)? Any idea on the service network in Calcutta would also help. Thanks |
