Q: I was told about a sealant that can be injected into air conditioners. Is that true? I have a small Freon leak in my AC so I’d like to know if a sealant will fix the leakage. I’ve been replacing about a pound of Freon every year.
A: Freon is a refrigerant that is no longer used in manufacturing air conditioners. Although you can still replace the refrigerant when it leaks out of an older unit, federal regulations say AC repair workers have to try to find the leak and fix it first. During these repairs, a dye is often injected into the coils though the process might not work that well. Eventually, you’ll probably find it might be more economical to buy a new air conditioner.
