Frequently Asked Questions
What is AC tonnage?
AC tonnage refers to the cooling capacity of an air conditioner. One ton of cooling equals 12,000 BTU per hour. It’s a measurement of how much heat the AC can remove from a space in one hour.
Why is proper AC sizing important?
An oversized AC will cycle on and off frequently, reducing efficiency and not properly dehumidifying the air. An undersized AC will run constantly but fail to cool the space adequately.
How does insulation affect AC requirements?
Good insulation reduces heat transfer, meaning your AC doesn’t have to work as hard. Poor insulation allows more heat to enter, requiring a larger capacity AC unit.
