  • Good value for routine maintenance
Size: 16oz
It is what it is—a straightforward maintenance product that seems to work just fine. Getting an 8-month supply for this price is a good deal, and it helps prevent clogged lines without any unnecessary fuss.

  • Read the instructions and you'll love it!
Size: 32oz (4pk)
Uncle Todd's works great! I used to pour bleach in my a/c units on recommendation of my HVAC guy but I started reading about the damage it does (plus we are septic which made me nervous) so I ordered this Uncle Todds. I pour it down the drains (4 units) every time I change the filters. I haven't had any problems at all and all my overflow pans are dry! I'm glad I stumbled on it. I feel like it's safer for my equipment and the value for the money is a bonus. The instructions are easy to read and initially I did have a small clog in one unit that I was going to try and suck out with my shop vac but I used this first and it's gone! Love my Uncle Todd. ... show more

  • No more AC clogs
Size: 32oz
Works flawlessly—finally a product that truly holds up against Florida’s humidity. As a property manager, I used to constantly deal with clogged lines, but since incorporating Uncle Todd’s into my preventative maintenance routine, I’ve saved a significant amount of time and money.

  • No more clogged HVAC drains
Size: 16oz
Uncle Todd's HVAC Drain Line Cleaner seems to work as advertised. I initially put clorox in the lines once a month until my heating/cooling system overflowed all over my garage. The drain line had clogged. After clearing the clog, I began using Uncle Todd's monthly. I have had no further problems and it has been over a year. Uncle Todd gets my vote for it's cost and efficiency. ... show more
