How dirty is the filter(s), also is the weather quite humid?if so it may be trying to stay ahead of the humidity,,did the TECH check for a pressure drop while he was there? and did he vacuum it down and nitrogen it and start from scratch? if it leaked down that fast it should have shown on the gauges when he performed the initial gauge test and w/o vacuuming it down,it could have moisture in the system and moisture will inhibit cooling

If my freezon would be low then why is it very cold air when I'm going on the road


because the temp difference between the hi and low side will be greater faster than a normally charged system the reason it cycles off is the keep the evap. from freezing up, but running to low on Freon can cause poor lubrication in the compressor causing damage to the compressor, yes it will blow very cold for a short period of time with a low charge

Why does my A/C condenser compressor turn on and off every 5 minutes?


You need good airflow across the indoor coil, the evaporator. Air warms the refrigerant. If there is no airflow, the refrigerant will come back out freezing cold (in liquid form) and can damage the compressor valves. Before charging any ac unit, good airflow must be checked for across both evaporator and condensor.
Too much, overcharging will cause freezing all the way back to the compressor in a capilary tube type of ac.
Where is it the refrigeration lines are freezing cold?

Not staying cool


sounds like it is either low on Freon or the compressor is going out. The blowing ice cold is an indicator that it may be freezing up because the low Freon. when it stops blowing cold, turn it to fan only mode and see if it gets colder again. If that is the case then the unit is low on freon and freezing up. I know that sounds confusing but that is how AC works. The low freon pressure means the gas is expanding too fast and the air flow cannot take up the cold from the evaporator fast enough. Turning the compressor off and keeping the fan on will alow the room air to take up the cold.

I have a 2006 Gulfstream Cavalier 8'x 32' Fema Travel Trailer with a Dometic Duo Therm AC unit which I have recently replaced the fan motor on. Had the dealership bench test motor prior to lea


There is ice forming on the evaporator coils. This is either from a low freon charge or a leak in the seals or windows and doors. Could also be that the drains are not working and water is building up and freezing

Coils freezing due to dust blocked coils and or air filter or short of gas. Service your unit completely.Please do not change any spare/s without knowing exact problem. Please follow the steps given below.

Toget proper heat, keep your temp setting at 30+ degree and also mode in "heat"position. If still no heat, check your heating sensor for closed circuit by anOHMs metre.It it's with RV, check power to RV.If it's with heatingelement check power to element. If power is there but still no heat meanselement defective. Replace new heating element. Thanks. To get proper cool, keep the tips as follows:
1. Check air filter is cleaned. 2. Check indoor coil is cleaned. 3. Checkindoor blower motor is working. 4. Keep in cool mode. 5. Set temp minimum 3degrees less than room temp.6.Check compressor is working with correctpressure.
Thanks. Helpful?

AC ran for a couple of hours and started blowing


If it is icing over, it is low on freon. You might have a freon leak if the system is relatively new. It will take a licensed tech to check, fix leak and recharge.

Unit freezes up.......Freon Leak?


Your AC unit is low on refrigerant. It should be recharged. be sure to keep the filter cleaned all the time as well. If this is an inexpensive unit, it may be cheaper just to get another one, since a lot of people would charge around $100. to charge it. hope this helps you, Rick
