AC units
I have two Duo-Therm 15k heat pump penguin AC units on our camper. One is down to 10 deg differential temperature suggesting it is loosing Freon. Compressor currents are nominal or maybe a little low....

As always to all thanks for the help. The coils are clean, not too long ago I checked the differential temp and it was running around 27 degrees (pumping cold air). When I checked the diff temp was only 15 and a day later it was 10 so I think it's a leak.
My penguins have the control board in the silver box located just behind the filter. Did not know there was an upgrade to reduce compressor noise. Due to the age, a thermostat that the display is just about faded away and the bedroom AC unit short cycling (something in the control board or thermostat) we have decided to just replace them with two new duo-therm Brisk air II's. Reports suggests 15KBTU act like 17K's and they are much quieter. I hope so the penguins are so noisy. I found a shop (a good shop) that will change them out this week so I think I will go for it.
