AC Freon Refrigernat leak sealer
Hello, hope someone can answer this. A year ago, we had Freon added to our 10 year old Rudd airconditioner by a local AC repair tech. Today, I noticed that the airconditioner wasn't cooling well (thermostat still registers 80 after several hours of running the AC). It is very similar symptoms as last year. I spoke to the tech and he said that he will come Monday to check and most probably there is a freon leak somewhere and he mentioned that there is a leak sealant that he can add for about $270.00. Has anyone used it and if so what are your results?
