What are some steps that I can use to Add Freon to a Window Air Conditiner Unit

[hvac1000]

You have to be EPA certified to dispense refrigerant/Freon.

I thought putting freon (which is not an environmental safe product) into an a/c had to be done by a professional for this very reason.

[Fr_Chuck]

Yes I would question where they are able to even get the feon

[hvacservicetech_07]

Take the unit to a pro, the cost isn't that high, and most likely you will rin the unit if you attempt to charge it yourself.

[hvacservicetech_07]

FrChuck, I'm not sure how they get it, but they do. I had a guy the other day that put 4 cans on 134a in his heat pump, which you can buy at walmart, and some people assume that's what the are supposed to use.

Taking it to a shop would be best. I don't think you should try to use r-34 for automobiles in it. That's the only refrigerant that you can buy without a certificate now, I believe. I am sure that you could make an adapter to install the r34 with, but the system would need to be evacuated and the seals changed. It's probably not worth it.

I`m wondering,, how you know for sure it even needs freon,, they can get dirty and need a good professional cleaning,, and usually takes care of the problem with window units,, very,very seldom do they get low on freon

[hvacservicetech_07]

Usually when a window unit gets low on refrigerant you are better off throwing it away.

[gary steele]

If you don't know what you're doing leave it alone. You could get yourself seriously hurt fooling with refrigerant of any kind without the proper gauges and some knowledge. I agree with hvacservicetech-07 throw it away. What you're are trying to do coulc be illegal as well good luck

Most window units are sealed systems
