I know to do temp differentials on ac, but do we ever do them on heat? If we do what are the parameters?

| Mark, there is not a temperature differential, I just take the output temperature at the vent registers. The temperature measured at the output for forced air systems should be as follows:
ELECTRIC FORCED AIR HEAT = 85 - 105 degrees F FUEL FORCED AIR HEAT = 105 - 145 degrees F HEAT PUMP FORCED AIR HEAT = 80 - 90 degrees F |
