Amps vs Watts: Apparent Power vs Real Power
Manufacturers publish electrical current in amperes, not true real power in watts. Multiplying volts by amps gives apparent power in volt-amperes (VA). Real power in watts equals volts times amps times the power factor. Single-phase induction motors commonly run at a power factor between about 0.75 and 0.88 under continuous fluid load, so treating published VA figures as if they were watts overstates true active power draw.

Reducing Electricity Cost: Control Options
- Thermostat control panels (such as Kasco C-10): Cut power when air temperature rises above a set point, reducing runtime hours.
- Thermostat plus timer panels (such as Kasco C-20): Combine temperature sensing with an off-peak timing window for further savings.
- Duty-cycling pulse controllers: A category of third-party accessory that cycles the motor on and off on a programmed schedule to reduce average power draw. Specific brands and duty-cycle percentages vary by manufacturer; obtain verified performance figures directly from whichever manufacturer you are considering rather than relying on a single unverified number.
