Gallo Drain Gun – AC Drain Line Cleaner Tool With Flexible Hose Pipe For HVAC Clogs - Includes 6 co2 Air Conditioner Drain Cleaner Cartridges

Came home one day and saw some water leaking out of the secondary drain line for my HVAC system. Not knowing much I called my HVAC guy who came out and said my condensate drip line was clogged. I watched him as he took a container of some type of compressed air and blew out the drain line. He suggested that I run some vinegar or bleach down the line every couple of weeks to prevent buildup which I did but I also came on amazon and found this tool. Despite running bleach down the drain line every few months, this summer caused the drain line to begin clogging again. I got this out and blew out the line myself, taking care of the issue without the HVAC service fee. The tool is very easy to use but definitely feels pretty cheap. It does not feel like it is very well made but overall it does the job and I have not have any issues with it. Would highly recommend this to anyone having issued with their condensate drip lines or even if you are not, just having one on hand would be a good idea.

It works great! It unclogged my line by the 3rd trigger hit.

Way too weak pressure and only CO2 enough for ONE (1) second blast. Thought this was a great concept to get my pipes cleaned for my central AC drain line. Instead, this device, while looking like it would do the trick, instead, was an EPIC FAIL. As others noticed here in the reviews, the product simply does not deliver enough "umph" to get the real clogs out. Instead, again, like others, I ended up flushing with water as this unit does not provide enough PSI (continuous) instead of a single "puff," and then the cartridge is used. The device comes with 6 cartridges, which "may" have moved the blockage, but certainly not out the pipe, and thus, when I flushed it with water, I was easily able to get the blockage out. I do not recommend this product. However, if you have enough cartridges, perhaps it will be enough so now, I am ordering the refill with 8 cartridges. Maybe that will make a difference next time.

I bought this back in September as a back up plan should my hvac drain line get clogged in the future. For months it just sat there until today. I got home and my hvac wasn’t turning on and water was dripping from the unit.I used this device. It took for cartridges but it finally worked. It got all the gunk out and cleared my lines. Even though I didn’t have to, I still ran a water hose to spray through the line just to flush out any remnants. But this device did the trick and got the main clog out. Pleasantly surprised.

Cheaply made but absolutely worth its cost considering the alternative is 50 bucks. Mine leaked a bit out of packaging but I tightened it up and it works fine. I am a hvac technician so I use this about 4 times a day and have gone through 20 cartridges so far with out issue. Works with threaded and none threaded refills.

I learned about this product from my AC repair technician. He used it and showed it to me then charged me more than $100 for the visit. I've now used this product three times saving me hundreds of dollars. Plus, I don't need to wait for the technician to arrive in a day or two. Easy to use. I mean, real easy to use.

One of the reasons I did not like this was that it seem like the pressure was not enough. It’s not compatible with other CO2 cartridges either. I found just blowing into the pipe was better than using this product . This concept is there, but the product was not.

Did what it's supposed to. My ac drain line was severely clogged. The drip pan was filling up daily. Product cleared out the drain line, ac has been running without issues. Product is easy to use.
