What I know is that due to Sunday's wet snowy weather my air-source heat pump became encased in ice on the heat exchange coils. You can't physically remove the ice without risking damage to the delicate fins, so I ran it in cooling mode for a while to warm the outdoor heat exchanger and loosen the ice.
I am a happy air-source heat pump user, especially when coupled with solar panels. However there are other issues people need to take into account, especially if it is difficult to access the device for cleaning or the owner is mobility impaired.
