I'll tell ya'll a funny story about power factors. Around 25 years ago during the early days of Air conditioning efficiency ratings being improved, Lennox put out a newer model 2 speed air conditioner. We started getting complaints from people that their bills had increased from their old 2 speed unit. So we found out that the new units were drawing 31 run load amps while running in high speed and 20 plus amps while running in low speed. The older units drew around 16-20 amps in high speed and around 10-12 in low speed. Lennox responded by telling everyone the new units were more efficient due to the power factor but never bothered to explain why a customers cooling cost were almost doubling with the new units. It was a complete load of garbage. The next model 2 speed units were back down to drawing the same or less than the older models. The complaints of bills doubling suddenly stopped. Go figure.
