The "heat strip" of your AC unit (if it's original) is really minimal.
On all three of my AC units around your vintage, in warmer weather, I cannot detect with my hand if the heat strip is working or not. In cooler weather you may be able to detect a heat rise, but it is minimal.
With a decent thermometer placed at the inlet louver get a stabilized temp reading, then get another stabilized temp with the thermometer in one of the outlet louvers....do not be surprised if the temp increase is only a few degrees.
The heater elements and the controls for the older units are fairly bullet proof but they actually put out very little heat.
