Is the a/c blowing warm air? If the coolant is not the issue, it may not be an efficient a/c, and has frosted up inside. Turn the unit off, and let is defrost. This will take several hours, but until the ice is gone, it will not allow air to blow through.

Does this unit dehumidify the room in which it is running, or just the air from the intake? As I understand it this dual hose air conditioner does not interact with the air inside the room it is cooling other than blowing the room air over the compressor to cool it...though I think I just answered my own question, as the humidity would condense on the compressor from the air inside the room, while the dual hose is designed to get rid of heat without creating a vacuum. Thanks.

Yes it does. Whenever you cool air, you reduce the amount of water vapor it can hold. As a result, if you are cooling room air you are automatically removing some of the moisture from the air as well. The condensate is probably re-evaporated into ... Air Conditioners

My air conditioner will not turn on. (See below for a more detailed description.) I recently bought a used Kenmore Room Air Conditioner Model 580. 76129. It worked well for about a month (running almost continuously, usually on either energy saver or cool).

My air conditioner is blowing hot air instead of cool air.. what is wrong with it? I have a Freyven mini split and the compressor turns on and off in a matter of seconds. It doesn't cool the room at all. It has The R-22 at the correct specifications but I just can't seem to figure it out. I have had several so-called technicians come and check it but it is still the same. What is the problem.

First if it turns on and off does this trip the breakers?? I'd recommend you to change the combination capacitor and check against wiring diagrams probably a misplaced wire that can do what your describing. check that you have your remote set on cool ... Carrier 38CKC042 Air Conditioner

We have just purchased a campervan with a Dometic B3000 Plus air conditioner. The temperature has been 27c & we have set the air conditioner to 20c & the room temperature will only come down to 24c. We have contacted the people who we bought the camper, but they reckon that we can't get the temperature any lower. I do not believe this. I thought that if you set the temp to 20c, it would cool the van down to 20c. regards Marie
