Haubeil Posted February 27, 2007 Report Share Posted February 27, 2007 I've read related forums and comment here on TIJ stating the exterior temperature was too cold to test an air conditioner unit. ...why? What exterior ambient temperature is the cut-off for acceptable testing? ...is there a default comment to use? I always heard the differential for air conditioner & heat pump units was ~30 degress. ...hence a heat pump's heat funciton is not efficient in the colder climate. Although, I've seen some heat pumps running while the exterior temperature was ~5 degrees. Is the ~30 differential a myth? ...because at 5 degrees, that would only generate 35 degree heat! Thanks in advance, Haubeil Quote Link to comment Share on other sites More sharing options...
