Direct Inject Dry A/C Moisture Remover (No Leak Sealant, Moisture Remover Only) - For Systems Up to 5 Tons - Converts Moisture into Synthetic Oil - Created and Used by HVAC Pros - USA Made

It’s an effective product to prep your HVAC before injecting Leak Saver Sealant to remove the moisture that’s harmful to your AC system. Easy to use with the CO2 injector that I bought.

I believe this added at least another ten years to the life of the system.As long as it's properly recharged.

Based on other customer reviews, we opted for a three step process spaced out over one week for our 2002 R-22 heat pump: 1) Acid Scavenger (wait 4 days) 2) Dry (wait one day) 3) Sealant with UV dye Each step brought an improved level of cooling and optimized the sealing effect on our system. It a bit more expensive to do three separate products, but each prepared for the next.

This is a great product for the pro or the DIYer like me. I have a cooling unit that has a capillary tube. It had a very slow leak(like 1-2psi /24hrs. I wanted to use their Leak Saver but wanted to make sure there was no moisture in the system. It worked very well and would use it again.

If you're not sure how long your system has been leaking out, I would definitely pre-treat your HVAC system with the moisture remover before adding the sealer. This will ensure you won't get any plug formation in your system other than at the leak site(s). Otherwise, moisture IN your system could form unwanted plugs and clog the system rendering it useless beyond repair. I did this to my old HVAC unit and it has been running strong for three years now.

Another worthless product from LeakSavers! When I opened up the sealed package I could hear the contents of the injection tube rattling around as a solid, which would make it extremely difficult to inject through a Schraeder valve into my AC system. Just to make sure, though, I cut open the tube to confirm that yes, the contents had hardened into a brittle, rod-like shape. Sort of like a hot glue stick, but not as flexible. This is the second of three Leak Saver products I purchased as part of a last-ditch-nothing-to-lose effort to keep my leaking AC unit limping through its last season. Number 1 was their 'direct inject' CO2 doodad, which was a sad joke (also reviewed); number 2 was this piece of garbage; and number 3 was a leak sealer with UV dye which I was planning to use after I injected #2 into my system using #1. I'll let you mull over the meanings of '#1' and '#2', but suffice to say that I doubt very much that #3 would be a charm, and I would be a fool to let any of this company's products near my AC unit, as effed up as it is. Their whole 'we stand behind our products 100%' is a lie. Stay away.

I’ve Used this product twice have had no issues, if you can’t pump a system all the way down to insure it’s dry before adding the sealant then you need to use this. As for the sealant it’s also worked both times for leaks inside a coil that wasn’t accessible. This is a lot cheaper to use that replacing a system.

It's 5 stars, but because this product is missing, there are only 1/2 tubes left, and the coupon is all defective, it can't be applied, hope the seller can overcome this situation.
