Your ultimate answer will need to take into account your climate and the age of your home, but you will need an AC size of between 40,000 and 70,000 BTUs, or between 3.5 and 6 tons. Since AC units only come in sizes of up to 60k BTUs – or 5 tons – you may need two units to adequately cool your home. The table below offers the electricity usage of a 5,000 – 18,000 BTU air conditioner. A helpful rule of thumb for calculating the electrical usage of an AC unit with 10 EER efficiency, a common efficiency rating, is that 1,000 BTU uses 0.10 Kilowatts (100 Watts) per hour. If the EER is lower, it will use more electricity; If higher than 10 As the mercury climbs, so does the importance of choosing the right air conditioner for your home or office. In the quest for cool, two contenders stand out: the tried-and-true window AC unit and the increasingly popular ductless mini split system.

If you want more cooling capacity without having to lug around a 7-foot fan, the Hessaire MC37M is a swamp cooler that is portable and efficient. The unit uses a 3-stage medium for cooling, unlike most others that only have a single-stage cooling material. 2) Cost and Pliability (The quality of being easily bent): Copper is costlier than aluminium, which increases the cost of making an air conditioner and thereby the price of air conditioner. To reduce the unit cost of manufacturing ACs, aluminium has become the favorite choice of manufacturers. So the difference between the two is basically the refrigeration effect that they can provide. In other words, a 1 Ton of ac would take somewhere around one hour to cool down the room. Simultaneously, a 1.5 ton of ac would take around 30-35 minutes to cool down the similar size of the room. Hence, the area of the room decides the capacity of .
