HVAC Guys Flow Tabs with Gel Lock Technology - 18 Pack - Keeps Drain Pans Clean, Prevents Overflow, 3 Ton Tab Lasts up to 3 Months - 1 Tab is equal to 18 Regular Tablets (324 total) - Made in the USA

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.

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!

Im in my 70's and I cant crawl around an attic where my air handler is like I use to. So when I'm doing my pre summer PM of my three ton central air system I stack two of these tablets in my condensate pan and Im good for the summer, one and done! No more putting half dozen tablets in every few weeks. The only con to these tablets is they dont last as long as advertised like some other reviewers have said. Thats why I stack them, but even then they are still a great value, and the two tabs last all summer. Hvac Guys make other products that are better suited in my minisplit system as well. I've tried a lot of different products by other companies but Hvac Guys products have worked the best for both of my systems.

smooth transaction,

I put a mini-split in my home office so I can condition just that space to the temp I prefer when I'm the only one home. I love it, but the condensate line starts getting backed up with "gunk" (super scientific term) after only a month or so and when that happens, the condensate tray holds water and the fan starts spitting it out into the room. I cut these tablets up into 4 pieces and slip 1/4 tab at a time into the condensate tray on the first of the month and that problem has stopped. It'd be cool if they made these even smaller for those of us using these for mini-splits, as they tend to crumble a bit when you cut them, but the product definitely works and it's worth the effort to keep the condensate line running clear.

These tables don't last 3 weeks, let alone the claimed 3 months... Put them in my units, and a couple weeks later, almost all gone...

I only recently started taking care of my AC(in a condo) and I saved so much money compared to having to call a maintenance guy and spend $300 every couple of years. I love that those tablets last 3 months. I also bought their coil cleaner and my new routine is perfect. Every 3 months I change the filter, spray the coils, drop a tablet and be done! Easy and efficient!

I purchased an automatic fluid dispenser to eliminate clogged up AC drains but I also purchased this product too, just in case! The price was right! I took one out and wet the bottom of it, then stuck it in the bottom of my pan. It stuck just like they said it would. I know I went a tad overboard but... I just wanted to be thorough. I think I actually bought 2 packs of these and they're going with me to my new destination.
