pretty amazing what they are doing with the inverter run dc compressors.. can slow them down and let them chug along as super slow speed .. but they are small units.. hard pressed to find ones over 3 tons. Most being 1 -2 ton units.. some having multiple evap cores.
Think part of the reason that we have not seen applications coming from domestic producers.. is that they have not been pushed .. mini splits are still not common here.. to many ding bat installers afraid to mess with them.. What part of simple and easier to install ??? I have not really figured that one out..
Yes I see lots of ashp with seer around 17 and cop right up there between 2 and 3.
My bottom line is conservation is still a much better solution than running the watt meter on the side of the house.
