Our goal is to bring you the best HVAC products and tools that we use ourselves in our daily jobs. We have literally tried everything! These are the products we stand behind 100%. Flow Tabs with “Gel Lock” Technology The drain pan is a dark and humid place. If left untreated, the drain line can become clogged, allow water to overflow, and cause expensive property damage. The HVAC Guys Flow Tab is an easy solution to effectively prevent clogging and buildup in air conditioner condensate drain pans. HVAC Professional’s Formula Set It And Forget It Each Flow Tab is equal to more than 18 regular hard pill tablets. The Flow Tab will dissolve completely at a consistent rate over 3 MONTHS to keep your ENTIRE pan clean and free flowing. Set it once and stop throwing in a handful of pills every single month! 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. Our Flow Tabs are made with a unique GEL LOCK technology that, when wet, locks the tab gels into place. It will not move around or clog the drain. Resize For Small Systems Or Add In Multiples For Larger Ones Each Flow Tab is made to keep a 3 Ton system drain pan clean for 3 months. If you have a smaller system, you can easily cut it to fit. If you have a larger system, you can add multiple tabs side by side. To increase the treatment time to 6 months, stack tabs on top of each other. Review: These a/c tabs are the best! We always use them to ensure our air conditioner stays healthy and does not clog. We live in Florida, so our a/c works overtime all the time. These tabs are perfect for a/c health and keeps the repairs in check. Review: This product outclasses by far all others I have tried on this site! The common type of white chalk-like tabs sold by other manufacturers last on average no more than a day or two and require constant checking if drip tray needs replenish. I can’t say if any of these orange gels will last a month or more as claimed (since I’ve only recently started using them) but I can confirm that a single tab ( the pack contains 16 ) split in two with one part placed upstream inside the drip pan and the other near the drain mouth of my 12 000 BTU split wall air conditioning's unit comfortably got me through a full week of severe heat wave. I expect 1 tab every two or three weeks should do a fine job while leaving your mind at peace and off spills and overflows onto your expensive floor 😩 By all calculations these cost less per usage than the gamut of poor products sold elsewhere. I highly recommend this product. As a plus they deliver a very subtle fragrance that is much unlike the awful moldy smell from AC that welcomes you when entering your home. ## Features - Causes serious eye damage. - Causes skin irritation. - Harmful if swallowed. - HVAC professional formula: Supercharge your air conditioner and refrigeration system maintenance with our HVAC Guys Flow Tabs with “Gel Lock” Technology.

Customer satisfaction is our top priority, and we are always happy to help! --- Zoey, Customer Service Manager **Q: Should I be using these during the winter season when we are not using the air conditioner? Also, can this tablet fit in a 3/4 drain line?** A: Hi B. Howard, Thank you for reaching out to us, and we appreciate your interest in HVAC Guys Flow Tabs. During winter, a Flow Tab would not be needed as when your system is in "heating" mode, there wouldn't be moisture dripping into the drain pan. However, when using your system in the summer in "cooling" mode, moisture in the air will condense on the cold coil and drip into the pan, which can cause mold/odors/slime to grow in your pan. This is where you would use the Flow Tabs. The Flow Tabs can fit a 3/4 inch line; for best results, you must place the tab on the drain pan, not inside the line. For your reference, the Flow Tab 3 Ton is 1 inch in diameter and 1/2 inch in height. We hope you find this answer helpful. If you have any other questions, do not hesitate to contact us directly —https://amzn.to/2Uw4SxW. ----Zoey Customer Service ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***O on 8 December 2025* These a/c tabs are the best!
