Any idea how to tell what kind of wattage our compressor runs on?  We have a split system...York 3 ton multi-position airhandler w/15kw electric heat and a Waterfurnace premiere cube unit....we haven't had an electric bill that was totally on the new heat system, but we are using many more kw hours than before.  THat being said, we replaced a gas furnace that we used very little in the winter b/c we instead used a buck stove with a blower and fans to circulate hot air...I think overall we're better off b/c although we have a higher electric bill, we have no gas bill and I think the savings will be better established over the course of a year.  But I'm a little concerned that we are not saving as much in electric as I thought we would...we are not using our aux heat (on the York air handler) at all. 

Pick up/order a Wattnode

KW is a thousand watts

KWH would likely interest you more , these measurments must be taken over time (H is for hour)

If you want to know Voltage times Amperage divided by 1000 and correct for Power factor ( estimate .80 will vary ) estimate run time , and estimate LRA on system KWH and you get a very estimated answer

In short pick up a Wattnode
