Fast Shipping! (6)-Pack NuLine HVAC Condensate Nu-Line Drain Cleaner, 8 Ounce

My repairman said to put about a third of the bottle once a month but I read the instructions on the bottle and it says to use the whole bottle every 90 days. It's a little difficult to pour in just the way my system is designed so I dedicated a plastic funnel to be used for the future yes it's not cheap but it's cheaper than having your air conditioning turn off in the middle of the summer and having to call an air conditioning repair man I live in a condo and the condensation line goes under our building and the only way to clean it out is to have something like this or a Shop-Vac and I have no Shop-Vac nor any intention of buying one my homeowners association refuses to take care of this for me even though it's in the common lines of the building.I will update my review if there's just not work

I used this to sanitize my air handler drain line last winter and I almost made it through the summer with no clogs. Normally even with bleach I still need to blow out my lines 2-3 times per summer because of my hot humid climate. So this liquid does work well to kill the algae/molds that tend to clog your condensation line.I just bought the 6 pack so have backups.

easy to use

I purchased this on the recommendation of my A/C service.

easy to use...pour in the drain lines every two months and the ac lines no longer clog up...would recommend and buy again

This product is recommended by a number of local A/C contractors, and they sell it to homeowners - at a much higher price than offered here. I use this product every 90 days in addition to pan tablets to help keep my line clear.

I've tried this product several times now and it simply doesn't work. I used it two weeks ago strictly following the directions. Today I vacuumed the drain line and it was full of gunk. It has no effect.

it was ok
