Default Re: testing AC in winter?

My two cents....it depends more on the inside temp of the house being cooled than it does the outside temp. The danger is the compressor trying to pump a liquid. If the inside temp is warm enough to give the condenser some heat (superheat) there won't be a problem. In Phoenix I start heating the house as soon as I arrive. Once I get it warmed up I feel comfortable in running the a/c.

Does this same rule apply to the cooling mode of a heat pump. For example, if the temp is 45 degrees outside, and it has been that way for 24 hours, can I not check the AC mode of a heat pump?
