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.

**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.

I have been using these since I installed my new AC in 2024. Used as directed and they work great! I use one tab per month (broken in half) in a 2 1/2 ton unit. One box of tabs last me 18 months. Well worth the price!
