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
Perhaps the HVAC industry should offer a $100,000 prize to an inventor to somehow reduce the defrost problem?
Summer time fins cleaning is also important.
My well intentioned sister replanted my mother’s garden and it looked great.
Then she hired a crew to mulch it.
This non-english speaking crew was throwing fine wispy black mulch with shovels, and decided to also “carpet bomb” the ground around the air conditioner by throwing in that general direction while the unit was drawing in air.
