Been using this AC drain line cleaner for a few years now and I'm totally happy with it. Never had a problem with backup or clogging. And when the AC guy comes to do his regular maintenance, the lines are clear every time. So I will continue using these happy with this product.

Easy to use & very effective. One bottle applies, and the system drained as it should.

This AC line cleaner was very easy to use, and I appreciate how simple the application process was. It seems like a great product for routine preventative maintenance to help keep the condensate drain line clear and reduce the chance of future clogs. Good value if it prevents even one back up. No lingering scent and it seems effective. The packaging is durable and the instructions are easy to follow. That said, if you're expecting it to dissolve or remove an existing blockage or heavy buildup, this probably isn't the right product on its own. I see it more as a maintenance product than a deep cleaner. The only other downside is that the entire bottle is intended for a single treatment, so you'll need to purchase another bottle for future maintenance.

This has made a real difference for my long drain line from the second floor unit. I found out after from an AC repair guy that my drain goes into the same drain out of my neighbors unit. My unit was backing up, to the point that the AC guy said to replace my AC. I did, and first day with my new AC it backed up again! The service guy couldn't clear it from my 2nd floor condo. He had to go downstairs and flush from the bottom. That's when he discovered our lines merging together on the 1st floor. I've been using this flush for over a year, and no backups! My neighbor says he's using it too!!

I have been using this to clean my HVAC drain lines and it works. I live in Florida so the HVAC gets junk in the lines and this is what I have been using to keep them clear. It has worked real well.

I don’t know what they put in here, but it is so dang good! I forget to add these every year and I had some over flow a few months ago and once I added this, no overflow!!! Total life saver.

It didn't really do much for me. I followed instructions and even bought a brush to go thru the line that would not flex for a 90 or 45 angle so I was hoping this would at least do its part. It didn't clean it out. My husband did something else when he got home from his trip and used something else and that worked. This did nothing and didn't work like it claimed. It went right thru the pipe and left foam at the bottom it didn't sit to clean the sludge and the pipe was still clogged after it went through. It seems easy to use but it just didn't work for me.

I had been putting up with a dripping AC for a few months. I emptied one bottle into the AC's drain, waited a day, and got no results. Emptied the second bottle, waited a day, still no results. I was putting up with dripping for at least a couple more weeks, as far as I can remember. But then one day, I noticed that my AC hadn't dripped in a long time, and it hasn't dripped in all the months since, despite still lots of use. As far as I can guess, it just took a long time to eat through the clog? So it seems to really work, if you're patient with it.
