RectorSeal AC Leak Freeze 45309 Leak Sealant, Easy Application, HVAC, .5 oz.

I will update the review if anything changes but so far this stuff has worked for me. I have a system that is almost 15 years old, r-22. Over the last few years I have noticed the cooling performance go down year after year. The coils and filters are clean so I checked pressure and realized I was a few pounds low. I ran this sealant through first and then topped up the system. I now have ice cold air. Obviously I need more time to verify the longevity of the patch but preliminary results are looking good.

WOW just WOW what a great product our coil had a leak called the AC ppl out they confirmed the leak and did add 5 pounds but told me the coil had to be replaced it's a 5 ton Goodman only 3 years old so still under warranty except labor and coolant he proceeds to quote me 1500 dollars and I said there is the door goodbye so I was desperate it's hot in Texas so my ADHD brain went hyper focused on how to fix it myself and found this product it's awesome I was able to get most of it in because unfortunately I didn't know a caulking gun isn't an option so I tried pushing it in by hand but it wasn't moving so I unscrewed it quite a few times then finally went got one of my caulking guns but it has a plastic body so it flexed too much then grabbed one of the all metal ones and like butter it went in so even with only 3/4 of it actually making it in our ac is colder than the day it was put in

It did not work in my unit but it was 26 years old and beyond repair. I replaced entire unit couple weeks later. I think it would work with less severe leaks throughout.

Works great

I have an under cabinet wine fridge with a leak that takes 1.4 Oz of 134a. I recharged it and it stayed cool for about 2 weeks before it goes warm again. This is 1/2 an oz, instructions say do not use more than 10% of total system charge, which is just a touch more than 1/8 of an oz or about 1/4 of the vial. It may work if your system takes 3.75- 5 oz of coolant (becasue 1/4 of the product remains in the feeder tube) but otherwise... Here's the problems. Its messy, hard to control, and it didn't work even at a very high dose rate. The feeder hose holds about 1/8 oz (which is 25% of the product wasted). You have to fill the hose before you connect it. There must be some type of check valve on the hose end that attaches to the syringe- so you really have to jam the plunger to get it started- then it spurts out everywhere, and you've wasted half of your half oz. (here's a tip, I've seen people put it in a caulk gun to force it into the high side, but that may also work to control small incraments into the tube.) Then, a system with a slow leak will have a negative pressure on the low side, so the minute you open the valve, the system sucks it in- its impossible to control the amount added, so 1/2 was added before I could shut the valve. (I probably could have taped 2 small shims to the cylendar to keep the plunger back to the proper amount, something to think about if your system takes less than 6-7 oz of refridgerant). Finally, it didn't seal the slow leak, becasue 2 weeks later here I am with a wine fridge at 70 degrees again, despite inadvertently dosing double. I added the remainder, the final 1/8 oz, to the system today, hoping a second dose would do it, and I'll let you know, but I wouldn't buy this product again. I would suggest a couple things to someone considering buying this product.. Buy a larger dose. More than you think you will need given 1/4 of the product is wasted in the tube on either end (1/8 oz to fill the tube, and 1/8 oz remaining in the tube after the plunger is depressed completely).

I was told by two different appliance repair guys that either the refrigerator couldn’t be fixed or it would be 1800 and they couldn’t guarantee the repair. I thought what’s the worst that’s going to happen if I try this product. I could still part out the 4000 dollar refrigerator if it doesn’t work. But it worked, the appliance guy told me it was a sealed system so they couldn’t get to places where there may be a refrigerant leak. I ordered this, I injected it and then filled the line with refrigerant. The refrigerator has been cooling beautifully for two weeks. There is a YouTube video that helps with the injection part. Took less than 10 minutes for the repair.

Crap, half of it goes on the ground they need to figure out a better way to fill the unit

I bought this a few months ago as my expensive side-by-side fridge leaked all of the refrigerant out. I spent $250 to have a repairman come out and add a valve to the compressor and add an ounce of refrigerant. After it leaked out 3 more times (and I learned how to use an automotive refill kit to top it off) I tried this. To my amazement IT WORKED!!! It has held the charge for months now and saved me from having to replace an $1800 fridge that’s only 5 years old. This stuff is kinda messy if you don’t know how to use it. I watched a video online about it and it took less than 5 minutes from unboxing until done. Best $36 I spent working on the fridge!!!

Légère fuite non visible après vérification par 2 entrepreneurs. Un entrepreneur m'a suggéré d'essayer ce produit, fantastique, la fuite a été colmatée avec le produit.

Efectivo y evita que desarmes tu tablero si la fuga es por el difusor, vale la pena, pero que lo apliquen después de hacer vacío al sistema, e inmediatamente ponerlo y el gas a continuación.

Missing parts very small amount off liquid in the injection and very long shelf life before purchasing

Was simple and easy to use. Unfortunately the leak was just to great for this to save my fridge.
