Features

  • HVAC professional formula: Supercharge your air conditioner and refrigeration system maintenance with our HVAC Guys Flow Tabs with Gel Lock Technology. Used by fellow HVAC professionals, our Flow Tabs are specially formulated to safely and effectively keep drain pains clean and free flowing. Great for central air conditioners, ductless mini-splits, heat pumps, refrigerators, refrigeration systems, and dehumidifiers. Designed for professional use.
  • Helps prevent air clogging and water overflow damage: If left untreated, the drain line can become clogged, allowing water to overflow and causing expensive property damage. Our Flow Tabs are an easy solution to effectively prevent clogging and buildup in air conditioner condensate drain pans.
  • Special gel lock no-clog technology: Most pan tablets are hard pills that can move around the drain pan. They can clog your drain pipe or be flushed out when the drain pan fills. Flow Tabs are made with a unique GEL LOCK technology that, when wet, locks the tab gel into place. It will not move around or clog the drain.
  • Easier to use than regular drain pan tablets: Set it and forget it! No more adding handfuls of tablets every month! Each Flow Tab will dissolve completely at a consistent rate over 3 MONTHS for systems up to 3 TONS to keep an ENTIRE pan clean, free flowing, and fresh. This is equal to more than 18 regular hard pill tablets (typically 2 or more regular pills need to be added per ton every single month).
  • Were here for you: Our company is owned and operated by HVAC technicians. These are the same products we use on our own jobs and stand behind them 100%. If you are not completely satisfied, reach out to us and we will gladly provide you a free replacement or refund.

    • It work and stay in place
Size: 18-Pack
Bought this ones as a replacement of other tablets that clogged the drain because they move in the pan towards de drain output. These were placed in the back of the tray like the others, but this ones stay were they were placed, so the pan stays clean and the tablets does not clog your drain output. They work just great. Highly recommended. ... show more

    • It de-slimed my window unit.
Size: 18-Pack
So after reading many review I decided on this product. I've been having an issue with my 1 year old ac window unit clogging. I live in Florida it is very humid and I run this unit year round unfortunately the drain to the drip pan started clogging. Luckly on window unit it is easy to access but it is hard to find metal cloth hangers these days. I did manage to MacGyver something to declog the drain. It didn't last long and I started to notice a slimy build up. After a 20 mins of Webucation and a few hours of review I got this product. At first I was cutting the in half to finagle the into the front drip pan but the desolve to easly when cut. I hope they decide to make smaller ones for windows unit. I started using whole disk in front drip pan. Take a little work to get it in the but seems fine. These things are amazing it de-slimed my unit and got rid of the musty smell comming from the unit. ... show more
