what does horsepower mean in A/C unit?

306 views

I don’t understand how an A/C’s power could be measured by horsepower. Is it the volume of air coming out? Is it how much colder the exhaust temperature is to the intake? What does it control exactly?

The manufacturer can’t make any promises about how much air their device will deliver, or how cold that air will be, because that depends a lot on the current temperature of your room, the humidity, altitude, position of the unit, and a bunch of other factors that they cannot possibly know. All they can do is say, “when you plug it into the wall, it uses this much power.” The primary working component of your A/C is basically just an electric motor, and motor power is typically advertised in horsepower.
