How expensive can A/C issues be?

I have a family member that wants to sell this class C RV to me (beyond cheap) but the vehicle A/C does not work. (The RV A/C is fine). I recharged it. It was very low but it still does not work.

I am wondering if it is major issues how expensive could this get to assure it has A/C. Even at a great price, I don't want to immediately have to put thousands into an A/C repair.

Hi,

That is a tough question to answer. Now that you recharged the A/C, does the compressor engage? If it does, then it could be related to something as simple as a blend air door. That is what controls the temp coming into the cabin.

Here is what I need you to do: I need to know what both the high side and low side pressures are in the system when it's running (that's if the compressor engages). You will need A/C manifold gauges to do this. If you don't have them, most parts stores will lend them to you. When you get these pressures, let me know the ambient temperature when testing.

Here is a link that shows how to evacuate and recharge the system. I'm adding it so you can see the gauges I referring to.

Also, take a look through this link. It identifies the most common problems related to the system.

Let me know as much as you can about what is happening. As far as costs, yes you could have $1,000.00 into it if there are a lot of issues such as a bad compressor, orifice could need to be replaced, condenser and so on.

Let me know as much as you can.
