ENVIRO-SAFE Arctic Air for R22 Systems, Proseal XL4, Prodry XL4, and Brass Gauge

This is worth every penny. Knowledge of air conditioning required. My home ac (evaporator) was randomly freezing up and system was not very efficient. After troubleshooting and cleaning I deducted there was moisture in the system. Added products per instructions and home ac is working like new. Thank you!

The product description on this page led me to believe that this product contains R-22refrigerant. It does not. After receiving it and reading the label of the cans, they allstate that they contain "Extremely flammable gas". That's not R-22. Maybe propane? In anycase, I'm not comfortable putting this in a residential A/C unit. This is not what theproduct was advertised to be. I've tried three times to return this. Amazon says ithas to go back to the seller, and that they would contact me; 2 weeks have gone by andthey are ignoring me. Also, this page says the seller is a company called "CME Biz", butthe order page says it came from "Cobalt Refrigerants", so there's a problem there, too,who am I supposed to return this to? And, if it's really a quality product I would thinkreturns shouldn't be a problem. This feels like a scam to me.

For 3 years I've lived in a 1968 Airstream with the original Armstrong AC unit still installed. This spring my expansion coil started icing over to the point where the AC was next to useless. This product revived my 56 year old air conditioner

This stuff is pretty easy to manage and get into your system. Be sure not to over pressure your system!It helped drop the output temps in our old A/C system by about 6 degrees. That made a noticeable difference in our house. Decent product for the money and we were able to find system pressure recommendations online.

Hard to return , still not able to get my money back. Not able to add to your unit . Only if totally empty.

Worked great in my AC unit
