A/C Sealant

It seems every year I need to add some freon to my AC. I have noticed there is a sealant available. I'm wondering if anyone has any experience with these and what their results were.

Thanks,
Steve

Not an HVAC guy but I would not use it - I can see it gumming up things you don't want. I would have someone find your leak and go from there.

Bad. very very bad. Your system has a leak but at least it runs. The sealant will most likely destroy the system making it not work what so ever. Not to mention no hvac tech will touch the system with that in it.

It's my understanding that those sealants work by hardening in the presence of moisture in the air.

If the original installer didn't do a very good job of evacuating the refrigerant lines and coil, adding a product such as superseal carries a risk of hardening where it shouldn't and trashing the system.

That being said, if your system is 20 years old and not worth a $500-$1000+ repair, a sealant might fix the leak and buy some time.
