please, I need advice before I pay a guy 700 to install a new compressor on a 2007 Nitro Sign In

Hello, before I spend 1000 at my local shop I wanted to at least throw a few posts out there and try to see if an auto A/C veteran could give me a pointer on something to maybe try.

My wife has a 2007 Dodge Nitro R/T 4.0 (She got the vehicle before we got together) -
In 2014, the a/c system got a complete overhaul. Compressor, condenser, evaporator, dryer, etc.
4 months later, they had to replace the condenser.

then 4 months after that, the compressor had to be replaced again, this was in early 2015.

Now, her A/C is not working properly. The pressure measurements are extremely high, and the compressor is spraying freon all over when the vehicle is revved up.

Prior to taking it to the shop it's sitting in now, I had a guy replace the expansion valve and change all the o-rings.

So now, the people at the shop I took it to want to change the compressor. (But, I feel like it's one of those jobs that benefits shops in hot climates, and that there may be an easier fix.)

Any advice would be appreciated, (I'm in Louisiana)

Mostly notes on this: A/C is its own bird and sub-trade with lots to know about it and failures set you back to where you were the first time up to needing more than it did then - lousy results long term if not done to the letter.


Louisiana (family there since 1972) I'm familiar with all seasons. From insane hot and humid to the "love bug" clouds can clog a condenser possibly more than can be cleaned from outside it with spray and a solvent can be in between it and radiator and the cause of assorted problems.
Now you are told just a compressor so it's already not making sense yet. That alone isn't usually the cause if a good one was there and done properly plus cleaning out all internal debris from a failed one or that will get caught up in even a new condenser again and again in turn take out yet another compressor playing constant ping pong of parts. Remanufactured compressors alone are a trouble spot to me. New and done right with other parts and procedures or you'll just be back at it again - pro shops included are not all equal. $700 bucks is chump change to A/C so alone smacks of a patch not a full fix.


Many original failures began with a leak, loss of cooling power plus the low charge doesn't carry lube to a compressor and the disaster happens.


These cars (other Chrysler products as well) are somewhat subject to evaporator failures more than average. One would hope a replacement would end that.


I'd seek another estimate from a very serious A/C shop that specializes in it. Price will probably end up a lot more than your current estimate and disappointing that some of the same parts already done will need to be replaced again.


No argument that A/C works lots harder there than many other places and unlivable without it. The end all is to seek another estimate based on your understanding if you want the longest fix or just patch it to get thru a season and do it all over again and again like seems to have happened already,

High pressure readings and a compressor blowing off refrigerant does not point to a bad compressor. Something else is causingnthose high pressures but continuing to operate it that way will also ruin the compressor.

You need to take that to an AC specialist that actually knows what they are doing. It appears this guy does not.

So right. For the moment compressor has the strength but probably self destructing also. Another is only a maybe to buy short time. This is probably debris down stream never tended to the first couple times.


OP - you asked for opinions of some techs now just two both think you need better diagnostics and better work than what you have been getting. Finding who or where is really the work you need to do,

Start by asking local mechanics who is the premier a/C shop in your area. Get several opinions, to confirm --the go to the place and expect to pay the going rate. It is obvious to me that these guys don't know what the hell they are doing, so run, don't walk away from them and never darken their door step again.
Stop acting cheap. Good mechanical ability from a through
tradesman is worth its weight in gold. Don't be foolish!
