I was wondering if anyone can tell me how to change the reading on my Heating/ AC unit to read Fahrenheit instead of Celsius.

It's in the owners manual if you have one.

From the manual to change from English to metric:

".....pressing and holding the driver's side TEMP/AUTO knob for approximately three seconds. Repeat the process to change back to English from metric"
