Air Conditioners
Are you considering buying a new air conditioner or upgrading an existing one for your home? When trying to understand an air conditioner’s power, it is common to find the acronym BTU.

BTU Meaning
This stands for British Thermal Unit, an energy measurement unit. Technically, 1 BTU is equivalent to the energy needed to heat one pound of water by 1ºF. In air conditioning, it is the unit used to indicate the quantity of energy used to remove heat from an area in an hour.

Proper BTU Calculation
