MANUAL J Residential Load Calculation Air Conditioning Square Footage Range by Climate Zone In order to scientifically calculate the right central air conditioner size, you can perform a Residential Load Calculation. Another way to size air conditioners is to determine the system size that is currently in place. The manufacturers do not list the air conditioner size on the unit. The system capacity will be coded into the model number of the outdoor unit. For example, model CKL24-1 is a 2 ton unit.

There are 12,000 Btu's per ton. 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. 24,000 Btu's/12,000 Btu's per ton = 2 tons Use the following conversion information to determine your existing system size (use the system model number NOT the serial number) 18 = 1.5 tons 24 = 2 tons 30 = 2.5 tons 36 = 3 tons 42 = 3.5 tons 48 = 4 tons 60 = 5 tons When sizing air conditioners, be careful not to make the mistake of getting one that is too large. If the system you install is too large for the space, it will short cycle. In other words, the compressor will not run long enough to dehumidify the space and will limit your comfort. In addition, it will cycle on and off more frequently, increasing operating costs and reducing the system life. Proper air conditioner sizing is critical to optimize performance.

Sizing air conditioners by phone is difficult but we can provide you with the tools to get you started. Heating Square Footage Range by Climate Zone Use the lower of the two numbers if your home is well insulated and the higher number if it is older or poorly insulated. jual ac portable mini bandung(Hint: Use the larger of the two numbers above if you're unsure of your home's insulation)ductless air conditioning unit reviews Simply multiply the appropriate factor above by your home's total heated square footage to arrive at your approximate required heating capacity. air conditioning repair service chandler azFor example, if you live in the yellow zone, your home is well insulated, and you have 2000 heated square feet, the equation will look like this:

X .40 heating factor (from the chart above) 80,000 Btu actual output Then, to calculate the output on a gas furnace, multiply its efficiency rating by its listed input rating for the actual Btu output of heat. For example, if a furnace has a listed input rating of 100,000 Btu's and an efficiency rating of 80%, it will produce If the same 100,000 Btu furnace has an efficiency rating of 93% it will produce: 93,000 Btu actual output For this example, using an 80% efficient furnace, the 2000 square foot home above would require a 100,000 Btu input furnace which will produce the necessary 80,000 Btu's output of heat.

Variables such as your insulation, type and number of windows, number of stories, construction type, etc. will greatly affect the required Btu's per square for both heating and cooling.

A general rule of thumb is that if your home is well insulated with newer style windows, you can select the smaller size system that falls within your total square footage. If your home is two story it will place less of a load on the system in the downstairs area as the second floor acts as additional insulation. If your home is not well insulated, has older style windows, and/or a larger than average number of windows, you will want to select the larger system which falls within your square footage range. The less insulated and more windows within the environment, the more likely you will experience greater air and heat loss.

Before buying an air conditioner, find out how many BTUs you need.  This means think of the size of the room, and what the room will be used for. Matching Btu requirements to room size is very important when you buying an air conditioner system. This air conditioner sizing tutorial will explain you how to choose the right air conditioner size. Choosing an air conditioner size that is too small (low BTU rating) for the intended room will leave you feeling hot and flustered! And buying an air conditioner that is too big for the room can have its problems too. So the main question is what does BTU mean? Btu – British Thermal Unit (Btu) is the international measure of energy. A Btu is the amount of heat needed to raise 1 (one) pound of water by 1(one) degree Fahrenheit. In HVAC industry, Btu's measure the quantity of heat a conditioning unit can remove from a room per hours. One BTU per hour is equal to 0293 watts. As the Btu rating increases, so does the weight, size and cost of the air conditioner.

To calculate how many BTU’s you need you can use this table. The following tables are estimates based on average room conditions in a moderate climate. Exceptions are Kitchens – add 4,000 BTU cooling capacity to the recommended size. High Ceilings/Unusual Floor Plans – increase BTU by 10%. Warmer Climates – may require 10-20% additional BTUs per room over regular amount. BTU size too large: A conditioner that has a bigger BTU rating than the room size needs will cycle off too quickly. The unit will not remove the humidity from the air properly. Air Conditioner size too small: A conditioner that has a smaller BTU rating than the room requires will run continuously. The unit will not cool the room adequately. NorthCool home air conditioner systems are normally 9,000 – 24,000 Btu's. This BTU rating provides sifficient cooling capacity for any home, condo or loft.
