RectorSeal AC Leak Freeze Pro Nano with Magic Frost 45317 Leak Sealant, Easy Application, HVAC, 1.5 oz.

I’ve used these products for years and have never encountered a mild leak it failed to permanently repair. The delivery system has evolved since I first started using these products. I was the GM of a restaurant for many years, and several older pieces of refrigeration equipment developed leaks over time (typically small and difficult to locate). This line of products never failed to fix these issues and verifiably ran for years without issue. Given this experience, I began to apply this product in central home HVAC and automotive HVAC systems. This particular purchase fixed a medium leak in a 3 ton split system, and the few drops left over fixed a small automotive leak that had been plaguing me for years. Now, the price has gone up about 3 fold since I first started using this product but still yet, my advice would be: If you can’t hear, see, or find the leak give this product a go. This newer delivery system is definitely easier and more efficient than the previous caulk-gun method (which is still sold). The build quality is very high with appropriately placed check valves and low loss fittings (I wish my manifold hoses were this nice).

Had to buy this for my 2005 Goodman unit that was leaking R22. Put this in and charged it up and it seems to be working like a charm. Don't know how long it will last, but I am hopeful it will get me through the hot summer months this year! This leak sealer plus a few hundred bucks in freon was a lifesaver!

Hasta ahora a funcionado en mi aire acondicionado. Tenías fugas casi indetectable y lleva ya un mes bien

It's been over a year with the Nano juice and the 9 year hybrid water heater is still pump out hot water. I had a problem with a slow but persistent leak around the Electronic Expansion Valve. I installed it per directions. The hot diode refrigerant detector finally stopped beeping like a evil Christmas toy. Getting another 16 months for $60 feels like a good deal.

My home ac was leaking some where, I had it filled it leaked out 2 days later. I bought this and had the ac tech come pump it in and refill my ac and it’s been working great this summer and it been some very hot days. Hope it works for the next person as good.

With this product you stand a 50 % chance that it may work. It all depends on your leak. In my case it did not work. But in many cases it tends to work fine and saves you from costly repairs. Keep in mind though that this is typically a temporary fix when it does work.

I was impressed by the device that contains the treatment. The instructions are pretty good, installation was easier than I expected. Oonly problem I experienced was I lost some refrigerant when removing the device from where it connected to the condenser unit. BE SURE to have on thick gloves and have good access to the connection so that when you begin to disconnect you can do so quickly. I was in a poor position and when I started removing the device. Some amount of refrigerant is sure to be released during removal, but I took longer than appropriate to complete the removal and lost more refrigerant than I wish. Probably my imagination, but the compressor unit actually does seem quieter and the temp drop across the coil seems to have improved some. I wish they had a similar unit that contained 12 or 24 oz of refrigerant so I could replace what I lost.

GREAT PRODUCT

my 2.5ton center air was leak in may 2023 I charge my system with the sealtech from canadien tire look like it's hold the charge for more then 3 moths .then I decide to try with this product and hope any better for permanent .after put in the rectorseal and fill up the system with full freon .
