BTU stands for British Thermal Unit and the measurement applies to home and businesses alike. Measure the room or rooms, place the measurements into the online calculator and it will turn the dimensions into cubic feet of air.
For example, a 5,000 BTU cooling system placed in a 5,000 square cubic feet should cool the air temperature by one degree per hour. An air conditioning calculator will show that the ac unit is suitable for a room measuring between 200 and 500 square feet.

The quantity and quality of your room insulation will impact on the type of ac unit needed. A warm kitchen increases the indoor temperature, so this factor should be taken into account too.
It is wise to ask the manufacturer to calculate the BTU to determine the size and type of air cooling system needed. however, some home and business owners will prefer to download an online calculator to work it out themselves.
It is important to leave a little leeway. For instance, if the A/C calculator advises purchasing a 10,000 BTU unit, you should consider investing in a 10-12,000 BTU home air conditioner.
The newly installed system won’t have to overwork to produce cool air to maintain the correct room temperature. Buy the right air cooler to lower your annual energy bills.
