After 2 power bills and a winter's use, the Ductless heating unit has exceeded expectations. Our power bills went from $350/2months to $210/2months and comfort level is amazing.
PNW has a mild winter climate with temp averages of 30's and 40's in winter with extreme lows to 15ish. The ductless performed perfectly in the 30's and 40s range, but worked a bit below 20 F.
