SOURCE: domedic duotherm 13.5, comp runs but no cool.

From what you've told me - I'm now thinking you're low on freon, and my advice (to you) would be to call a Service Tech who can (a) find the leak (b) fix the leak and (c) re-charge the unit with the proper charge.

Of course you can always put a 'tap valve' on the AC and try to charge it yourself - but unless you have experience with this kind of work, and the proper tools, i.e. gauges and welder - you will not be able to repair the leak (it will almost invariably need welding) - or properly re-charge the unit.

In any event - if a 'leak' is your problem - you should be able to get a Service Tech to fix it for you - for around $100-$150 without a problem.

good luck!

No cold air. Unit runs fine.


There are a variety of probable causes of your AC's failure to blow cool air. Unfortunately, it is difficult to diagnose your situation without being there. However, I have a great, handy diagnostic article that specifies the main problems so that you can definitely come to find the cause applicable to your AC's failure. I'm not too familiar with RV AC's and how they may differe a bit from house AC's, but your AC very well may need a recharge of refrigerant/Freon by a technician, but short of that, try this first:

This should defintely help.
Good luck!

You probably have a dirty condenser coil or the con den ser fan motor is bad or the blades are jam that's why it overheat and shut off by overload.

Install a second DuoTherm A/C in a fifth wheel travel trailer.


You do not without removing wall board. You can do a nice neat job of white conduit on the outside of the wall and ceiling. I have done it and my customers are happy with it.
