Leak Saver - Leak Shot HVAC - Leak Sealant Injector and Condensate Line Blaster - Non-Contaminating CO2 Cartridges - for A/C and Mini Splits - Systems Up to 5 Tons

IT WORKS!! As first-time homeowner I had trouble with my AC condesensate line clogged. It hasn't been maintained and flushed out over a few years. I tried pouring vinegar, hot water and other AC drain products to help it flush but nothing. I found this product and decided to take a chance on it. It solved the problem in less than 30 seconds. I read and followed the instructions how to properly use it. It worked as intended and saved me $$$ having to call our HVAC tech to come out. I only had to use 1 out of the 3 Co2 tubes. We're happy to beat this high summer heat!

I bought these for the times when you just can't get to a drain plug to clear it out with ease. It works great. I just wish there was an option for half capacity canisters, as they are one-shot deal, and sometimes you just don't need the full force of a cartridge to do the job. Would prefer a variable trigger that allows one cartridge to be sparingly used between 2-3 units when it's just for maintenance sake on hard to access units (and not a full blown clog). Still a 5 star product.

After a year plus of use, the cap of my Leak Shot injector cracked and became unusable. I called the company to inquire about a replacement part and they immediately sent me a new unit, additional CO2 cartridges, and even apologized for the inconvenience. The customer service team was extremely friendly and helpful and I was never put through a phone tree or required to provide anything other than the order number. I really appreciate how easy they made the entire process.

Product works great. Advertising led uv light for free. Not true. They will never send it.

Absolutely next-level trash! Bought it for the hose and the condensate drain stopper attachments (and you could probably find them elsewhere at half the price), because the cartridge housing/trigger mechanism is ridiculous, like some cheap piece of plastic your kid might get with a McD's happy meal. The housing barely punctures the CO2 cartridges, and then they pssssssst out at wheezy low pressure without even pulling the trigger. Don't even get me started with the 'Refrigerant grade CO2' cartridges, LOL (there is no such thing, unless your AC actually uses CO2 as a refrigerant). My HVAC happy meal came with the O-ring in the neck of the CO2 cartridge holder broken, although since the O-ring serves no discernible purpose in the joke that is this product, I can't really complain about that. What I can complain about is the insultingly bad build quality - search for 'Schraeder valve CO2 inflator' and you'll find a ton of all-metal devices that do what this preposterous joke of a pseudo-product pretends to do, at 1/3 the price. Shame on everyone who brought this flimsy trinket to market.
