Almost! But not quite. BTU stands for British Thermal Unit — and it’s a measure of how much energy an air conditioner uses to remove heat from indoor air within an hour. Too many BTUs, and you may end up paying extra in energy costs. Too few, and your AC will run constantly trying to reach a temperature in a large space that it just can’t cool. A Trane Comfort Specialist can help make sure your units BTUs match the size and scale of your home. Learn more about BTUs at https://bit.ly/43xL9CV | Tr
