works great for a mini split!
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.

FINALLY A TABLET THAT DOESNT QUICLY MELT LIKE SUGAR CUBES
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 canโt say if any of these orange gels will last a month or more as claimed (since Iโve 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 ๐ฉ 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.

Good product
I had no idea these existed and I had no idea they were necessary. They solved my problem. The drain overflow pan in my attic HVAC had started dripping through my vent. The pipe that directed the water outside filled up with life. These tablets did a great job.

Great product
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.

Works great!
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!
