Power-Factor Drop – When Electricity Works Against You

Every motor in your HVAC system should use power efficiently, but when the power factor falls, you pay for energy that never becomes work.
Chatterbox continuously monitors the system’s PF curve. A falling PF—often caused by a weak capacitor or imbalanced load—means your compressor or blower is wasting energy.
After replacing a failing run capacitor, the system’s PF rose back to normal and power consumption fell nearly 20 %. Real data proves what the homeowner feels: smoother starts and cooler air at a lower cost.
