There are many ways to objectively measure the power and output of an HVAC unit or system, like a heat pump or even a Goodman 5 ton AC unit.
You can measure the system in terms of BTUs, or British Thermal Units, to give an indication of how much raw power a system can deliver in heating or cooling.
You can measure it in terms of tonnage.
You can also assess the horsepower of the blower motor because that will impact how effectively the unit can circulate air.But these are all just numbers, and for most homeowners and business owners, they are fairly abstract.
For most of you reading this, you’re probably looking for some way to get an impression of how to correlate the power or size of an AC unit to the size of a home or business.
The orientation and configuration of your homes and the rooms in it will also affect the performance of a cooling system.
