Air Conditioner is an inherent part of an household with summners getting hotter. You should consider your needs and do your research before finalizing the one you want to buy. AIR CONDITIONER FEATURES Size / Capacity The size of your airconditioner is very important. You need to think about whether you are cooling a single room, a selection of rooms or the entire house. If the airconditioner is too small you won't cool down and you'll waste electricity running it on high all the time. If, on the other hand, you choose an airconditioner that's too large for your needs you'll have to switch it off regularly when you become too cold. Switching it on and off all the time will also waste energy. The Ton of air conditioning indicates the cooling capacity of the air conditioner. One ton of air conditioning is 12,000 BTU. A BTU is short for 'British Thermal Unit' and is the amount of heat that will raise or lower the temperature of one pound of water by 10F.You should keep in mind that actual capacity is not constant and will change based on outdoor or indoor temperature. The published rating of a unit is based upon capacity when the outdoor temperature is 950Fand the inside temperature is 800F. The chart below will help you decide the tonnage for the air conditioner for a 12-14 feet high room. Area in square feet Tonnage of AC Less than 90 0.8 90-120 1.0 120-180 1.5 Greater than 180 2.0 You can also check AC Tonnage Calculator from LG Energy efficiency Check the energy rating of the airconditioner you are considering. All airconditioners should have an energy-rating label which uses stars to rate the efficiency. The more stars the better. Also on the label will be an energy consumption box. The lower the number, the less it will cost to run. Airflow The fan in the airconditioner circulates the cool air around the room. Look out for airconditioners with a variety of airflow settings. While a high setting is good for cooling a room quickly, it can be quite noisy so you need to be able to adjust it to a lower level that keeps the room cool but quiet. Noise level It may sound pedantic but you need to check how noisy your airconditioner will be. If it's noisy, not only will it annoy you in your home but your neighbours may be affected too. Timer A timer lets you switch your airconditioner at certain times even when you are not at home. This works well to cool the house down an hour or so before you arrive home. Ionisers Ionisers can emit a stream of clean, fresh, negatively charged air. This reduces airborne odours by producing traces of ozone that can reenergize the enironment.
