What are the benefits? The Patented KVAR UNIT is a UL/CSA/EPA listed product, has a FIVE year warranty and with a 6% to 10% energy savings the investment return is 36 months or less. Lower monthly power bills, decreased heat dissipation in all inductive load appliances, thus extending their productive life cycle and complete power surge protection for the entire home or office.

Web page sure looks classy. Here's the patent:

Manure. Cap banks will do nothing for most of the residential loads. Mostly cause the utilities do not bill by Power Factor for residences.

Ditto.
1. As SQLit said major effect of increasing the power factor is only of economic advantage if the utility meters the power factor and charges for it. Not likely on residential.
2. Propaganda on reducing residential killo-Watt-hours (power) by about 12% IMHO is bullshit. With low power factor the Volt-Amps may be reduced but not the power since power takes into account the phase angle between voltage and current.
3. With a low power factor there would be some reduction in current and thus some reduction in heat loss in wire. This would be quite low in residential. Connecting the device at the service, as shown, will lower the losses in the wires from the meter to the service, as short run of large wire.
4. From what I saw in the patent application, conviently supplied by Roger, the amount of correction is manually set with switches. If you have one motor running and correct the power factor, the correction will be wrong if you turn off the motor or add another motor (or turn off 1st motor and turn on 2nd motor). Over correcting (when the 'motor' is turned off) is also a problem.
