Calculating the Right AC Sized Needed For Your Property

Getting a new AC system installed means a significant investment for the betterment and comfort of your home. Since it’s a big investment, no homeowner would like to go ahead and start with it without 100 percent confidence. In the majority of situations, the confusion is regarding the size of the AC that would suit your home or office. 

This problem mainly occurs with the first time buyers having no idea of the area or size of the property and how much capacity to focus upon when it comes to buying an AC unit. 

On the other hand, this is something very necessary and to be measured before investing in any kind of AC unit including reverse cycle air conditioning St Clair. 

According to the vendors, there are a number of reasons why this factor of the size of the unit gets overlooked. One has already been mentioned above, i.e. the size of the property and the second is the measuring unit and the formula that often sounds very confusing. These reasons force people to focus entirely on the size or the energy rating and nothing else. 

Vendors say that AC units are measured on the units of tonnes and BTUs, i.e. British Thermal Units. The "ton" measures the cooling capacity of the machine per hour and then, the "BTU" determines the amount of electricity consumed by the unit/hour. 

Generally, one ton is equal to 12000 BTUs and this way, two ton means 24000 BTU and in the majority of cases, residential AC units have the capacity of 1 to 5 tonnes. If your home needs more than five tons, you will require a tandem system with two smaller units to equal the larger tonnage requirement.

Vendors of air conditioning St Clair say that there could be some serious consequences of using incorrectly sized AC unit for your property. The smaller sized AC unit will not be able to meet the demands of the home and on the other hand, the bigger sized AC system will consume more electricity and then, shut down on a more frequent basis to impact the compressor’s integrity. 

Constant shutting down and switching "on" will leave the interiors more humid and uncomfortable for dwellers and mostly, people with breathing issues.

In terms of any kind of AC system including reverse cycle air conditioning St Clair, this calculation can be done in a couple of ways. For determining the BTU, you will just have to get the square footage of the area you want to cool. 

For example – if the area is 1500 Sq ft, you will have to multiply it with 25 and the outcome would be the BTU required by you. As far as calculation of TON is concerned, you already have the square footage of the area, i.e. 1500 for example, you will have to multiply it with 30 and divide by 12000.

1500sq. ft. X 30 = 45,000

45,000/12,000 = 3.75 tons

This clears that the AC tonnage required to cool an area of 1500 Sq Ft efficiently would be 3.75 tonnes.
