Air conditioner needs freon

My Coleman mach air conditioner on my pop up needs to be replaced, per a friend. He said when the freon is gone, so is the unit. Is their a part that can be replaced and just add freon.

    it could be that your generalizing your conversation with your friend abit,but its not exactly true that when the freon is gone you need to replace the unit .heres only takes an once or so to have leaked and it will not cool properly,so in some cases you can top it off and it will cool again.but by law this can only be done if you are tring to find the leak.which can be very hard to you top off ,look for leak,none found and in most cases it will last a season.there is a higher probability that the gas will leak out in an system that's not being used,because the gas equalizes and there is pressure on the low side that's usually in a vacuum while another way that your unit could be shot,is if it was empty[or near empty]for a while then moisture contaminates the sealed can open it up and replace the dryer,but if 134a gas, it has low tolerance for moisture and can be a you may have to pay a technician just to try but they could not grantee the results.if its 134a system you can buy that gas at walmart and try to charge your self.the gas goes in on the low side,which is the fatter copper line at the would have to get a line tap from an appliance store to get into the system though

If the system runs you will first need to add freon to the system (make sure it the right freon) Just enough to find leak. After you find leak and repair evacuate the entire system and weigh in charge. Hope this helps.

I have a friend who has a 2006 chevy Four Winds RV says its out of Freon which freon does it use? TY

R14 is what is now required. Freon, as you knew it in the past is no longer legal to use, in almost all circumstances.

Hope this helped you. Please let me know. Thanks.

How to add freon to a coleman mach model# 8633-876 serial # 089817583 do you suggest r12,or r22 freon type. is this a easy procedure or does it take a ac person? the problem is it not cooling to full...

It's R-22 and you need to be licensed to handle it, if you're not a A/C service technician or fimiliar with charging an A/C system, then it is best to have a Coleman Service Technician to charge it for you.

Air conditioner does not cool

Well, letting things sit that long isn't good for them. It probably lost it's charge of freon.No way to fix that.

I don't think you need a new one just a good cleaning and service. The unit has a liquid high temperature line near the compressor with a fan blowing outside air across it this coil gets clogged over time with air-borne dirt and pollen and leaves and such and must be cleaned regularly or the unit will be unable to remove the heat from the coil and during the peak demand (3pm) the circuits that protect the compressor and the trailer wiring from being overloaded and burning or melting will trip. From what you have described it sounds like the RV is working as it should with a condenser coil that needs to be cleaned. GL and happy camping!
P.S. I've only serviced the occasional RV unit but in those cases I laid a piece of plywood on top of the Rv for work platform removed the retaining screws from the top cover and used a spray bottle with a good heavy foaming cleaner a shop-vac and a brush to get the job done.
