BTU ( British Thermal Unit)is used to evaluate energy . Specifically , it is a measurement of the amount of energy required to heat a pound of water by one arcdegree Fahrenheit at ocean level . When used with air conditioners , the higher the BTU evaluation , the swell the energy output of the appliance . This imply an air conditioner with a high BTU military rank will cool a house best than an air conditioner with a low BTU rating .
In some case , the output of the tune conditioner may be express with aBTUh ( British Thermal Units per hour)rating . This is fundamentally a measurement of how much vigour the atmosphere conditioner uses to remove heat from the home within one hour .

However , this rating can also be stated in tunnage , with 12,000 BTUh adequate to one ton . These terms are not as common , but it ’s still significant to understand what a net ton is and that there is a difference of opinion between BTUh and BTU .
7 Air Conditioner Size Considerations
Before catch into the necessary calculations to find the right air conditioner size of it , it ’s important to see about the various factor that can touch the heating and cool down demands of a home .

Start bymeasuring the square footage . If you ’re only buy an air conditioner for a individual room , you only take to measure that elbow room . For whole - home plate air conditioner , it ’s necessary to appraise the square footage for each room , then add the amount together to find the square footage for the intact home .
An air conditioner generally demand about 20 BTU per straight foot of be space . Once you ’ve cipher the straight footage of the elbow room or base , reproduce the result by 20 to find the breeze conditioner size for the home . For lesson , if the square footage of the home is 2,000 square feet , you may find the right air conditioner size by multiplying 2,000 by 20 . The result , as present in this chart , is 40,000 BTUs .

Frequently Asked Questions
As a cosmopolitan prescript , aim for 20 BTU per square foot of living distance . Once you ’ve compute the room or home ’s straight footage , multiply the consequence by 20 to find the match BTU .
The square footage to BTU computation rate is the same for HVAC and window units . However , window whole are typically best suit to small spaces , as the big residential units typically only go up to 25,000 BTU .
Look for a high-pitched SEER military rank , which stands for Seasonal Energy Efficiency Ratio and show how Energy Department - efficient the breeze conditioner is based on standards set by the US Department of Energy . And / or look for the ENERGY STAR ® certification , which is given to gadget that have a high SEER valuation and use 8 % less energy than conventional new model .
fit in to theU.S. Department of Energy , " ENERGY STAR qualified central breeze conditioners must have a SEER of at least 14 . By kick upstairs from SEER 9 to SEER 14 , you may reduce your energy usance by more than 35 % . If you are paying $ 100 per month in direct temperature reduction costs , you could reduce your monthly utility bill by up to $ 35 by switching to the SEER 14 betray air conditioning organization . "
