How to measure the volume of an air conditioner

Before you actually go to the hardware store and buy yourself an air conditioner, you need to measure the right volume of the air conditioner, according to your needs. You need to do this because otherwise the efficiency will be lost. If the air conditioner is too small, then the machine will struggle to maintain the temperature.

If the machine is too large, it will cool the air too much and unevenly. Here’s how you should do it.

  1. First of all you need to measure the room in which you’re going to install the air conditioning unit.
  2. Think about how many people are using the room, because more people means more heat.
  3. Think about the air source: window or hole in the wall.
  4. If the walls are insulated, then the air conditioner volume may decrease a little.
  5. Also see if there are any other appliances in the room that can generate heat (like a few computers).
  6. Usually, air conditioner volumes are measure in BTUs – British Thermal Units. This is the cooling capacity. If you are more comfortable with watts, then 1 watt = 3.4 BTUs. This capacity implies that your house can handle the wattage and also that it’s just perfect for your home. Measure the square footage of the room and then multiply it by 20 and thus you will get the right capacity in BTUs.
