What Size Air Conditioner Do I Need?
Size is important, especially when choosing the perfect BTU size for an air conditioner. Choose a unit too small, you could end up with an air conditioning unit that overheats or with a space that is not cool enough. Otherwise, a too large air conditioning system for the room will not remove the necessary moisture from the space, making it feel humid and uncomfortable.
What Is A BTU?
A BTU or British Thermal Unit is a measurement of the amount of energy that is required to raise the temperature of one pound of water by one degree. That might not seem handy when it comes to air conditioning your business or home but the calculation is critical to keeping cool and comfortable. Each air conditioner or heater is rated to produce a certain number of BTUs.
