I live in south Florida. I recently had a Rheem 5 ton a/c system installed in my home (models 14AJM56A01 and RHLLHM60xx). I was told that they system also includes a 10KW heat strip.
During the heat cycle, the temperature coming out of the closest duct never goes above 88 degrees. This does not vary based on internal temperature (i.e. 68 or 78 degrees) or external temperature (i.e. 40 or 70 degrees). I was told that this is because the system includes a heat pump, however, I would think that since the system includes a heat pump that the interior heat gain would decrease as the outside temperature drops. All my tests show that nothing affects the temperature coming out of the ducts (consistently 88 degrees).
Can someone tell me if this is normal? Shouldn't the temp of the air coming out of the ducts be hotter when it is hotter in the house or when it is hotter outside?
Also, I can't find the technical specs for this unit, can someone tell me what the delta t is for my unit?
