HVAC Drain Line Cleaner – 16oz / 8 Months Supply Bleach-Free, Fast-Acting, Long-Lasting AC Drain Line Solution for Tough Clogs & Buildup

I put about 1/4 of the big bottle in from the starting point upstairs near the stack where you remove the cap, let it sit for 20 min. Then went outside and turned the wet vac on with it connected to the endpoint of the drain line ... went back upstairs to the other end, poured boiling hot water down from the starting point, flushing the solution out... I repeated the process with only a 5 min wait this time inbetween solution and boiling water ...and immediately heard that fantastic whistling sound through my drain line from the vacuum suction ...which equates to a perfectly clean and clear line. I'm talking 4 years of bulid-up, with no prior cleaning effort whatsoever, ..GONE! ..cleared out in 30 min. This stuff is GOLD!! You will NOT be disappointed!! Thank you Uncle Todd!!

The stuff does work. I had a really bad AC clog BASICALLY BECAUSE THE PVC PIPING WAS NOT INSTALLED PROPERLY. WATER DOESN’T RUN UP and I did have to use an auger on the indoor part, but it did help a lot and once your pipes are clear to use it on a regular basis would be amazing. It’s not going to get rid of a major clog without you doing some work. I used it on my indoor part which had the major clog and I had to take everything apart, but I used it on the area that runs from the house to the out side and when I had my unit cleaned about a week later, he barely got anything out and I hadn’t had my unit cleaned in a year. It was brand new so I definitely think this did a lot because these pipes in this condo where I live are from 1973.

Easy to use and I love that it doesn’t have a strong odor. Had to clear a clog in my AC drain line. Tried a shop vac and flushing the line with white vinegar and hot water. Decided to give this a try. Followed the instructions on the bottle. My clog must’ve been pretty sturdy because it took on get than the indicated time for it to clear, but it finally did!

This stuff works but….Ok got this bc summer heat coming and drain got clogged and ac unit stopped running as it should. Ordered Unc’s secret sauce slowly got small bottle down (whole thing didn’t care about directions lol) waited 10 mins went back and water in pipe went down! Turned on unit and boom no issues. Has been working for about a month now issues.Called local AC handyman to come clear lines and he took out a buuunch of junk but was still flowing. So I give this stuff a 4/5 stars bc yes it did help in the pickle I was in so for that 100% worth it, but as a magical it will fix it all I don’t think so. I would still order this product hands down don’t get me wrong.

We have an almost brand new central AC system. When it was installed the drainline was professionally cleaned. I have been using 2 ounces of this in the line on the first of each month. After 2 months the line appears to be emptying efficiently. I will monitor this as we move forward. With the very hot/humid weather approaching here in S. Florida, I am interested in seeing how this solution works on a long term basis.

My floors were being drenched with water with our a/c running all the time in Central Florida. I tried vinegar and hot water, tried vacuuming the lines but it kept overflowing onto my floors. I bought this cleaner and it cleaned my clogged pipes at once. Extremely happy with this product. Now I just need to maintain every two months. Thank you Uncle Todd’s Drain Line Cleaner.

I have a shutoff float in my drain line and with the hot humid weather, the condensation water wasn’t flowing fast enough to allow my AC to keep running. This quickly opened the line to the outside. I plan to use a little each month to keep drain (15’ long with several 90° bends) open.

Badazz AC drain cleaner....forget bout clorox opening a line...use this stuff...works great!
