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

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.

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.

Love the idea of these, but you need to know how to open up your furnace to get to the condensate pan. I love that you can stack these and get by without adding tablets for maybe a year or so. For most, you may want a spray version from the V brand. You can spray it in the pan and also the condensate pipe.

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.

I recently had my central airconditioner yearly service and the technician asked if I wanted him to install a tablet that kept the drain pan clean and the drain line from clogging. I asked how much and he said $70.00. I know how important it is to keep the drain line clear to prevent water from it from clogging up and overflowing in the house. I did some shopping on Amazon and found HVAC Guys flow tabs for less than half the price and enough to keep my drain clear for several years. They are easy to install and do a great job. Great product and I highly recommend them.

These tabs keep my condensate pan, pipes, and sump pump clean with no clogging.I use 1/4 of a tab inside my pipe; it stays where I put it.

we use these in hvac dehumidifiers for swim schools and with that high of humidty they do not last long at all and do not work as well as they do in a basic hvac system.

Recomendado. Muy bueno.
