Is higher BTU better for air conditioner?
A measure of an air conditioner’s power is its BTU rating. BTUs are the energy used to remove heat from a room. Therefore, the more BTUs an air conditioner unit has, the better equipped it is to cool a larger space.
Is higher BTU more efficient?
This is calculated by BTUs (British Thermal Units) divided by watts used. For instance, if you have a 12,000 BTU unit and consume 1200 watts in an hour, the EER rating is 10. The higher the rating, the more efficient the system is.
How many square feet will a 3 ton AC cool?

How is cooling capacity of AC calculated?
To estimate your AC tonnage needs, multiply the number of square feet you’re cooling times 25. This equals the total number of BTUs you need to adequately cool your space. Next, divide that number by 12,000 to determine the tonnage capability you need in your new air conditioning unit.
What is BTU for AC?
BTU is short for British Thermal Unit, a unit of measurement that shows just how much energy your air conditioner uses to remove heat from your home within an hour. It may seem overly technical, but BTU is an important metric that can help you determine the kind of air conditioner you need for a home your size.
How do you calculate cooling capacity?
Using the energy equation of Q = ṁ x Cp x ΔT we can calculate the cooling capacity. We add 273.15K to the celcius to convert it to units of Kelvin. The Specific heat capacity (Cp) is measured in units of kJ per kg per Kelvin.
