54RegCab; you said;.....[Sounds like the installing contractor fubed this job, should it be running 100% when it's -10F outside?
Well, I certainly hope the contractor has (in your words) "flubed" a lOT MORE of these jobs.
The cycles are a lot less,maybe 1, at the most 2 within any hour ,even at a -10f temp outside. the home is still a comfy 72f

"running at 100 %? lol ,get real, eh?
