DO NOT USE IF YOU HAVE HARD WATER!,

This review is from: Cool-n-Save System (Misc.)
Great with PURE water but a horrible idea if you have any hard water at all. I assumed the cartridge filter that came with the unit would filter out the calcium & lime from our hard water. It did not! Within two weeks, my condensing unit fins had started to lime up and I could tell the fan was having to work harder to pull the air through the unit. I have tried using CLR, LimeAway, and other similar products to no avail. I have since taken the Cool'N'Save off my air conditioner and I'm about to throw it in the trash. I have a feeling the manufacturer will find a reason to blame me for the problem as I doubt they will buy me a new condensor. Worse case scenario, I may have to replace my complete A/C system because I tried saving "up to 30%" on my cooling bill. Rough estimate for a new A/C is between $2500-3500. Is it worth it to risk that?
NOTE! One thing for the potential user of this to remember is that most outside water spouts do not get softened by a water softener!

2/5/2012: product review updated and rating cut to 1 star today... see end of review.
this product DOES work to increase AC efficiency... there was a Tulane study of it that measured it's heat transfer increase at the condenser at 40% and 70% humidity ... the short story being that there was at least a 70% increase of heat transfer on the coils.
Another reviewer stated that if you have a humidity over 40% this is not effective.... per the Tulane study that is false... this is a water pre mister for standard residential Freon type AC units... it works by wetting the fins on the gas condenser so that the water evaporation increases the condenser transfer to the air... it is not using water as the primary evap mechanism... his statement was correct for water coolant vs gas... just about every house in the USA has gas / Freon so this is a good product for them regardless of location.
So it does increase heat transfer to the air at the condenser by...Read more

Ridiculously Brilliant!,

This is such a ridiculously simple concept, I can't believe it's not just everywhere. It was VERY easy to install.
One neat thing is that it doesn't spray water all the time, just when the a/c is on. I don't know what the effect of moist air will be over time - I don't want mold - but the A/C works just fine in the rain, so I'm not really worried.
After two weeks, looking at my own meter, it doesn't look like my A/C bill is much better, but it's tough to say just yet. I'll post updates later once my bills come in.
August update: it looks like my electric bill is indeed going to be lower, though I think it's by about $50. However, the flap that turns the water on when the A/C is on, and is supposed to turn the water off when the A/C is off, is getting stuck, so it's frequently misting 24 hours a day... causing me all sorts of issues, and running up my water bill to boot. It's a good thing that we're reaching the end of summer because I was about...Read more
