AC Not cooling

I have a similar problem. My AC is running but it's not cooling down. When I got up this morning it was cooling fine. The temp was at 70 but as the day has progressed the temperature has progressively gone up and is now 78. This has never happened before and has been very sudden. Air is blowing but it's not cold. Any ideas??

Does the fan always run


Cooling fans only run when the temp,of the coolant get to about 215 to 218 degrees,and shut them selves off,when the engine cools down,if they do not cut off,the engine is not cooling down,now,if the ac is on,the cooling fans will stay on until the ac is shut off.

RV AC unit won't cool, blows chuncks of ice


It's most likely an airflow problem, you say you had the vents closed? Icing up is normally caused by lack of load (air flow) or loss of refrigerant charge. Make sure all your vents are open to allow for as much airflow as possible and that your filter is clean. Some units do not work well on low airflow setting when the outdoor temps cool down at night.

AC not cooling during the day


Your AC cooling efficiency is low when he ambient temperature is high and naturally it cools well when the outside temperature drops.

Please remove the filter on the grill and try to clean it under the tap water and after removing all the dust fix it back to the unit. This would increase the cooling efficiency of the unit.

Your AC is also five years old. Please avoid frequent opening of doors or windows.

Ensure that the exhaust fan and the blower of your unit are functioning normal.

The technician might not have done a proper job in fixing the area where the refrigerant would have leaked out. Please check the refrigerant pressure to ensure that no further refrigerant leak has taken place. Or even servicing your unit he would have punchered the tubes resulting in very slow leak of refrigerant resulting in no cooling or less cooling. It takes around a month to feel the pinch of it and the refrigerant. One fine morning after sometime the unit will run and it would start throwing hot air instead of cool breeze!

AC stops working when cabin temp reaches 109-110


indicates gas pressure and condenser cooling problems
check the condenser fan is working properly and have the gas pressures checked by gauges
check that the evaporator fins are clean and not blocked as ice build up will cause the same indications

You have lost some charge in your system. I would have a mechanic top off the charge but also add some refrigerant oil as well. The cool will often slow down at an idle, but should not start to blow warm.

Cooling fans will only turn on if engine is off only


Electric cooling fans do not run all the time. They will only come on if the engine exceeds normal operating temp. Also will run when AC is on. Easiest way to make sure they are operating properly is to first verify they run when the AC is on. Next turn the AC off and run the engine at 2500 rpms sitting still and monitor the temp gauge (don't let it get into the red). The fans should come on after 10-20 minutes (depending on outside temp.). As the engine cools down they will turn off.

sounds like your pressure switch is bad.as the temp outside gets hotter the more pressure is built up in your ac so when the pressure gets to high the pressure switch shuts down the system to prevent damage to it.Did u put any more r-134a in to the system if so then the pressure will be to high and the switch is doing as it is supposed to.Thanks for using fixya
