Many contractors use a rough estimate of one ton of air conditioning for every 400 square feet, according to the U.S. Department of Energy. This is done by calculating your square footage.
AC BTU Calculator.
AC Unit Size Calculator accurately estimates the size of the central air conditioner unit you should install in your house. The size (cooling capacity) of your air conditioner is determined by the amount of Btu (British thermal unit) and the Tonnage (12.000 Btu = 1 Ton). Btu and Tonnage Calculator. When we talk about air conditioning, a “ton” is the measurement of a units ability to cool. For example, model GSX140241K is a 2 ton unit. If you have a one ton AC unit, it means it has the ability to cool 12,000 BTUs an hour. There are 12,000 BTU's per ton.
Try it now and make a smart decision. The system capacity will be coded into the model number of the outdoor unit. Why?
The manufacturers do not list the air conditioner size on the unit. Assuming the minimum cooling capacity of 400 square feet per ton for your HVAC unit, a 1600 square foot home will require 4.0 tons of air conditioning to cool.
AC calculator uses your house size (square feet), climate zone, efficiency and equipment type (standard central air vs central heat pump) to show you exactly what size central air unit you need.
Residential central air conditioners come in a range of sizes from 1.5 ton to 5 ton models. Learn how to calculate the amount of AC tonnage required for a room with our Tonnage Calculator. Blue Start FIXED SPEED SPLIT AIR CONDITIONERS . To illustrate, using this method, a house with 2,000 square feet would need a 5-ton unit.
To figure out what size air conditioner you require, you first need to determine the amount of BTUs you require. Get the cost of 1 ton, 2 ton, 4 ton and 5 ton ac unit. Use this calculator to estimate the cooling needs of a typical room or house, such as finding out the power of a window air conditioner needed for an apartment room or the central air conditioner for an entire house. What amount of Btu and Tonnage should your air conditioner have in order to properly cool your home?
BTUs stand for British Thermal Units and refer to the amount of energy your air conditioner is using per hour. Although this calculation is often inaccurate, using it for comparison purposes might help you catch math errors. Enter Area of Windows (in square feet) Air conditioners are sized by the number of BTUs they put out. The number 24 in the model number indicates the unit is 24,000 BTU's, divided by 12,000 BTU's per ton, equals 2 tons. Your HVAC unit will need to remove about 4.0 x 12,000 BTUs, or 48,000 BTUs, per hour to keep your home cool.
