Nu-Calgon 4296-60 Pan-Treat Scum 200 Tablets

Great to keep your HVAC in a better condition when I was replacing my AC filter I’ve noticed that there’s a thick sludge in the drain pan and thise tablets helped me to dissolve it. Highly recommend.

Live in FL and prior to using this on a weekly basis, my A/C drain line would clog with "growth" every few months depending on atmospheric conditions. Using this "as directed" -- I have a 4.5 ton A/C, I use 4 (not 5) tablets per week -- has worked to keep the drain line free and clear of the "growth" I would see previously. I feel that this is a good product that works as intended.

My HVAC tech (Parobek) recommended these to keep the overflow drain clear, and they’ve been great so far. I just drop one tablet into the small overflow tube and leave it to dissolve. They fit just right. I wear gloves since the tablets are a little chalky, but they’re easy to handle and take seconds to use. They dissolve slowly and keep the line clean without any smell or mess. For the price, you get a ton of tablets - enough to last a long time - so the value’s solid. It’s one of those simple maintenance steps that saves you from bigger problems later.

Tablets for keeping heat pump drain lines clean. 1.5 ton air handler uses 3 tabs internal pan, add additional monthly. My hvac man said ri toss 2-3 in back corner of overflow pan and 2 in internal pan, add new ones monthly. If internal coil pan is hard to access you can dissolve in warm water and pour in line directly (my unit has two drain lines with blow out access points. Medium to large size tablets similar to denture soak tabs. Good price for years supply vs buying bottle if liquid and convenient to use (no spilling, no jugs of vinegar and funnels needed. Use heavier dose on first use then can use approx 1 tab per ton thereafter. I’ll do anything not have yet another leak from attic

Good price, good quality product, quick delivery. This product is used to keep drain pan & drain lines clean and clear.

My house was 5 years old when I bought and it always had condensation overflow. I tried everything to drain, clear, and clean the issue. But it continually happens. I accepted my fate and the fact that the evaporator was not leveled properly during installation. So I placed 2 large plastic tubs underneath to contain the output. Then having to check and dump the tubs religiously. I also tried cleaning the coils with the foam spray to no avail. Not having much hope, I gave these tablets a try. It is a game changer. After the first round with 2 tablets on each side of the drip pan in the groove next to each coil, the issue cleared up magically. So now I just have to put in 2 new tablets every month. Hope someone with the same issue will find this review and use this product to save yourself the trouble and costly AC tech visits.

This is for Maintenace of my A/C. I monthly no water is necessary. It keeps the h20 exhaust pipe clear.

Unfortunately the how to use instructions on the bottle doesn’t say how many tablets to use each time , found instructions on Amazon , will try what it says
