Question : Can automotive AC recharge kits be used to recharge home air conditioners?
Hi! I am trying to top off my home air conditioner that uses Freon. Can I use AC recharge kits that I can purchase from automotive store? If so, which refrigerant should I look for? My home air conditioner is atleast 20 years old.

No way. Dont even try it. Do you know there is over 100 psi in your system, which that kit doesnt have. You will lose more. You need a professional to do it. Im sure you have a leak some where too since you lost refrigerant. I can only assume that your system is R12 since its 20yrs old. You wont find that any where as a consumer and if you do its really pricey. You need to know how much to charge and use the gauges. I recommend have a professional out look for the leak repair and recharge. In order to purchase that kit or any refrigerant you need to be EPA certified. If you buy from a supply house you need to have a HVAC contracting lisence or work for the company.

Not sure but if you live in the U.S. you need to be licensed to purchase and use freon or most other kinds of refrigerant these days. Gone are the days of the avg. Joe buying that stuff.

Sorry

My best answer for you is to goto a home depot or call a heating/air conditioning place in the phone book..I don’t think u can just goto a automotive store and by a kit and use that freon..try finding out what your home air conditioning units model and seriel number and maybe looking up your freon info there..but if they made kit for automobiles universal for homes too then it would say it was universal for home.be very careful when messing with freon because if you have a leak it can be very dangerous.sickness/death.. just make sure you gather as much info as you can.

Yes- you absolutely can. If you have an older system, you may need to change the service fittings. Always add to LOW PRESSURE side of the compressor- it will suck out of the can. (the high side is about 200 PSI and will blow the can up, splattering with burning cold aerosol).
