Even down here in the Arizona desert they ice up pretty quickly. My guy said a heat strip takes care of that but I won't like the electric bill that comes with it. Heat pumps are pretty good air conditioners but not so much a heater in my opinion.
You sir are the only person that addressed the question on the ice build up across multiple forums including those on HVAC
When my brothers new unit was icing up it took several service calls to find out there was a loose wire in the unit. There's a difference between icing up and defrosting. Defrosting keeps it from icing up. If a unit is icing up somethings wrong or it's not rated for the cold temp it's trying to be run in.
Do you happen to know what the outside temps were? we were well into the minuses
been 40's and high 50's lately. they are supposed to be out Tuesday
Kinda feel a bit back burnered but it is a warranty job (pays less) and I do have heat so
