It is true that it is a sealed unit and should never need charged with freon unless a leak has developed. Most service techs will tell you that they cannot be recharged because you do have to break into the sealed system with a solder in valve or a line tap. They hold such a small amount of freon that finding and fixing the leak can be next to impossible and time consuming. Make sure that the inside and outside coils are clean. The outside fins can be brushed with a semi-soft brush like a toilet brush and then washed out with water. Make sure your power is off first. If the coils are dirty it will act just like it does if the refrigerant is low. 75 to 80 percent of air conditioner service calls are solved by cleaning the outside condenser coil. Brush up and down and do not put so much water pressure on it that the cooling fins start bending.

Friedrich CP24F30 money saver mode not working


Money saver mode dose not regulate room temperature. All that mode dose cycle fan on and off with the thermostat if in the yes position then fan cuts on and off with the call for cool. if in the no position than fan runs all the time even when cool is not needed. that switch is like the auto/on on a thermostat for central air. the thermostat is what regulates temp in room.

Why is a brand new in wall ac not dehumidifying room


could be to small for room or could be to big for room. It the unit is too big it will cool the room down to fast and shut off to soon, this will not remove the humidity. Try running the unit on a lower temperature the slower the fan the colder the coil which will remove more humidity from room also make sure the fresh air vent is closed and not bringing humidity from out side.

Hi, The air con in my 2003 Audi A6 1.9 tdi 130 is blowing warm air the air con rad is fully gassed and all fuses are ok . Thanks in advance for any advice on how to fix


The only other thing then would be if the compressor is turning, engaging, and the cooling fan working properly. You should either be able to see the compressor clutch engage, as the switch is energized, or at least hear it click loudly when the switch is energized. If it is not, then there are sensors for the low pressure/high pressure line to tell the compressor when to function, that also have to be checked.

As the engine runs with the compressor turning, one line should be hot/warm, the othe,r (larger diameter hose) should be cool/cold, if the system is working properly.

If the compressor is turning when you have the A/C turned on, then see if the cooling fan is running as well. It must run to remove the heat and cause the process to function properly.

Good luck!

My Freidrich air conditioner is 2 years old. It seems to run very "rough" - it's hard to explain the sound I'm hearing. Still cooling off the room.


Sounds like your unit is maybe unlevel causing the fan blade to rub or its not draining properly and the fan blade is running through water and should be pulled and cleaned.

My friedrich unit compressor wont come on


This could be a bad capacitor or your compressor may have gone bad. Another possibility is an overload that is tripped and has to be reset manually. Hope this helps.

Air conditioner comes on fan only. the compressor doesnt seem to be coming on. the is no cool air blowing. the unit is brand new and was jusy installed.


there will be option in remote to on the fan and compressor separately may be you would not have on-ed the compressor through remote or else there would have been any loose connection in the wire which connects the compressor
