A. This is a possibility.  Thanks to innovations in tecnology, such as the hyper-heating inverter, heat pumps can now keep a home toasty warm even if outdoor temperatures drop to 0^ºF!  That's a big improvement over the heat pumps of the past, which became ineffective when outdoor temperatures reached the freezing point (32ºF).

A. Most systems should run about 2-3 cycles per hour.
