If the compressor is not engaging, you have a freon leak. Figure a grand or so for a refurbish of your system.

How would I know if compressor is engaging or not....when the engine is running I check under and the compressor is turning since it's belt driven and I had someone turn on the AC it seems no difference/noticeable changes of how the compressor turns.....how is this compressor should look like or sound like when the clutch is engaging or disengaging?

The clutch assy freewheels until engaged so it may look like the compressor is turning. With someone inside the coach to turn on the A/C you should be able to see or hear the clutch engage when the A/C is turned on. If not then some permissive isn't being met, low Freon pressure is one item as mentioned.
If you can reach the leads on the compressor a voltage check with a meter will show if the permissives are being met. Use caution not to get fingers, hands or clothing caught in the belt.

In dash AC

I was having same issues with my 2009 Hurricane, everything has checked as far as mechanical but come to find out the return vent on the floor was sucking dog hair in and plugging the coils. It still had air volume coming from other areas but couldn't pull air across to cool down then circulate. Tonight I will put a piece of screen over it to catch so as not happen again..hopefully.

AC update

No dog hair after a camera was used instead of tearing dash apart plus a lot cheaper(5 mins instead of a couple hours) then more checking they found a bad expansion valve. Checked the air today and was blowing 38 degrees now. Thanks for ExtraRide Policy 200.00 ded and they picked up the 510.00 portion.

I check and recharge a/c units on cars all the time. One way to check and see if it's just low on freon like others said turn on the a/c and look at the compressor. In the middle of the pulley(where the belt runs on) check the center and you should see it spinning with it. If it is spinning and stopping over and over again that means you are low on freon. If it's spins constantly and not getting cold chances are you may have a leak in the line and its out. Look around the 2 a/c lines and condenser and look for bright green fluid. That's the oil in the system. If you see it that's usually where the leak is.
