It is going to be a much hotter this summer. And so, it becomes all the more important that you pick an air conditioner whose capacity is just right to get the best cooling for your room at an effective cost.
What tonnage AC should they buy and whether it will be sufficient enough to keep our room cool? Generally, if one asks this question to a salesman, their utmost attempt would be to sell you the maximum ton Air conditioner, which in fact, will be more than required to cool the room.
Buying a smaller capacity AC can be evenly worse as it will have to work harder to cool the space thus resulting in high electrical bills and leaving you empty handed at the end.
Today I will give you all the information that you’ll ever need to buy the right air conditioner this summer.
Room size determine AC capacity.
|Room Size||AC Capacity|
|Up to 100 sq. ft||0.8 ton|
|Up to 150 sq. ft||1.0 ton|
|Up to 250 sq. ft||1.5 ton|
|Up to 400 sq. ft||2.0 tan|
Air conditioner size is rated in tons and the sizes available in between 1/2-ton increments. The average commercial AC size ranges from 2 tons for small buildings to as much as 30 tons for very large buildings.
The reality is that when looking for a new AC, people just go to the market without knowing what size BTU unit will cool a certain area of their home.
Does Size of Air Conditioner Really Matter?
As a matter of fact, yes it matters. Pick too small a unit, you could end up with a room that is not cool enough, or with an air conditioning unit that overheats frequently- A Big No!
On the other hand, a larger unit for that specific space will not remove the necessary moisture from the room, making it feel uncomfortable for the people.
Space is not Just One Thing You Need to Consider
While space is one thing, there is another factor involved to calculate the right amount of AC tonnage. Apart from just dimensions of a room, you need to know the number of windows, floor, insulation, number of appliances in a room, facing direction, available power, fans available, humidity, wall type, city of use, furniture type, time it is to be used, orientation to the sun, number of people in room & outdoor conditions.
There is no universal answer to this question but one can estimate the applicable amount of cooling required based on their situation, surroundings & requirements.
The simple rule of thumb is to get all measurements. Using any measuring instrument, you can get readings to calculate the size of the room to determine the BTU requirement of the AC.
