Temperature Differential for Coleman Mach AC
Have a Coleman Mach 15000 BTU AC unit. Does anyone know what the temperature differential between return air and discharge air is? I know on cars and houses it should be about 20 degrees F. Thanks.

Normal difference between inlet and outlet at the unit is 18 to 20 degF with the fan on high speed.
If you are getting 25 to 29 degF difference, you have a problem. First thing to look at is reduced air flow, low fan speed, dirty filter, leaking from inlet to outlet.
In the south, anything over 30' length needs two A/C units to have a chance of keeping cool in the summer.
