Question about Ruud UBHC Air Conditioner
I have the temp set at 73, but the air at best is luke warm if not just a little cool. I have had the unit for 4 years (new). Temp outside is around 6 degrees and inside 69 although thermostat is at 73. This is a 208/220 unit. Any idea where I should start looking at?
Turned out one of the heating coils burned in half.. The coil was a 13Kw coil (I think that is what was said). Anyway, so 4 out of the 5 were working. Cost of the part was $170.

That's crazy, we're having the same problem. Turns out there was a wattage restrictor in the furnace that was switching off 3 of the 5 heating elements in an attempt to save energy. Basically, the restrictor was sensing that the incoming air was warm, so only 2 of the 5 coils should be needed to heat the air. Well that wasn't enough and we just sat with the furnace running all day long struggling to reach the 70 degree setpoint.
This is something a technician can diagnose in a few minutes, but not the sort of thing a DIY'er should really handle.
