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

Works great on AC drain to prevent mold and clogs.

This is my second purchase of this product and it works. Easy to install. Drain line is clean and I will continue to use Uncle Todd’s product.

Worked good no more overflow drainage!

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.

Regular usage (small amount about 2oz. Every other week) really works well! Florida is tough on slime build up so the effort to pour just a little in twice a month will keep the unit running perfectly. Had tried vacuuming with frequency as well as other products and had backups once every three months or so. Since using this have had no issues:)!!

Works great! Good to have handy in the house!!

My A//C was clogged. I tried everything. So tried this pour it in gave a few minutes rain warm water down the hose and wow it unclogged my a/c drain pipe. So happy.

Yes cleans line buildup well but also killed my no float pump causing it to fault and pump continuously. Washed off electrodes and pump is still shot. Was better off not doing the preventative maintenance to start with.
