Time Saver:If you’re looking for a quick & easy calculation and already know the principles of CFM and ACH, use the Navigation tool to jump to thePick HVAC CFM Calculatorwhich gives CFM needed based on the number of ACH your space requires. OK, for most of us, let’s take it a li...
On top of that, when you usethis calculator for how many BTU air conditioners you need, you will also have to understand what AC tonnage that is. Conversely, when you use theAC tonnage calculator here, it might be useful to convert those tons into BTU to give you a better understanding ...
Calculate heat transfer rate, Q. Q is measured in units of energy per unit time, such as BTU/hr or Watts. For a wall of uniform thickness d, with a thermal conductivity of k, an area of A, a hot temperature, Thot, and cold temperature, Tcold, solve Q with the following equation:...
How To Calculate How Much kWh Does AC Use Why are we are always talking about tonnage and SEER rating? Simple. How much electricity air conditioners use is directly proportional to: AC capacity (tonnage). The bigger the unit, the more electricity it will use. Energy efficiency (SEER rating...
9,000 to 12,000 BTU – that’s .75 to 1.0 tons aka tonnage. Mini split for 1500 square feet? 36,000 to 45,000 BTU depending on where you live and home conditions. That’s roughly 3 to 4 ton mini splits. How do you calculate mini split size? The exclusive Pick HVAC Mini Sp...

knowntonnage(or BTUs), theSEER rating, and theHSPF rating, we can calculate almost exactly how much electricity a heat pump use (watts, kWh usage)per hour,per day, and evenper month. Based on that, we can calculate how much it costs to run a heat pump per hour, per day, and per...
According to The U.S. Department Of Energy recommendation for the size of room air conditioners: “…an air conditioner generally needs 20 BTU for each square foot of living space.” Based on room size, ceiling height, and other conditions, you can calculate how many BTU air conditioner you...
