About Mistbox

The Mistbox, found online at Mistbox.com, is a new product that you can attach to your outdoor air conditioning unit in order to conserve energy and save money on your AC usage.

How Does It Work?

According to this website, the Mistbox says that they can save the average homeowner up to 30% of the energy normally consumer by their air conditioner with a product that can be installed in just ten minutes.

The Mistbox control unit will use sensors to detect the operations of your AC unit. It will then determine to when to use their misting system to create a fine water mist around your AC condenser in order to pre-cool the incoming air. 

Their website says that their system “uses a proprietary combination of advanced water treatment technologies to ensure water mist cannot harm your AC unit” and that a specially designed turbine generator powers your Mistbox using the exhaust air from your AC condenser. 

Finally, the Mistbox also connects to a mobile application which the homeowner can use to track its operation and to see just how much they are saving on their monthly bill.  

Cost/Price Plans

This product does not actually appear to be sold through this website at this time, so customers will need to go to the various third party websites and stores that carry this product. Though the website does not carry a complete list of retailers that carry the Mistbox, it does appear that major brand names Amazon.com and Lowe’s are currently offering it.

Refund Policy

Because this product is being sold through different third party websites and retailers there is no one single Refund or Return Policy that will be applicable to all Mistboxes. You will need to refer to the specific policy at the retailer from where you purchased this product.      

Customer Service Contact Info

Customers who would like to contact Customer Service with any questions, concerns, or complaints can do so by phone at 800-481-6478 or by email at [email protected], or by submitting them directly to their website through the Contact Us link.


This product appears to get mixed reviews at best, with a variety of customers complaining that this product simply does not work the way that it should, and many people saying that they don’t believe this product was created by people who had a good understanding of the way outdoor air conditioning units work.

Not everyone felt this way about this product, but it seems that enough people felt this way that customers who are considering investing in this expensive product might want to make sure that they are purchasing it from a website with a reliable Return Policy, so that if they experience problems with this unit they know they will be able to receive a portion of their purchase price back.       

Competitors and Alternatives?

The Mistbox is not a completely unique product. The idea of using an additional water mister to cool down the hot air going into your AC unit so that it can be processed more efficiently has been around for awhile already, so customers who aren’t interested investing in this product may be able to find a different product that better meets their needs.

Zero returns, buyer beware

July5, 2020

I bought my unit once they got rid of the annual service and let you own it outright. The concept is plausible and having worked in the hvac trade I can tell you most techs have done similar setups on Av units they were trying to limp along. The bonus to this and why I bought it vs a diy system that turns on and off with the compressor is this unit supposedly limited its use to only the times the unit was running at high head pressure. The system was also advertised as working through and app that allowed you to monitor the use.
Day before I received the unit I got a message that the app “would be spotty if it worked at all”. I installed the system and tried the test mode, nothing. Tried it again, nothing. Next day tried it again and the rest worked. Great! Well that was the last time it ever sprayed. Checked the app nothing. $200 down.

Was really excited about this product. I installed it right away. ( READ THE FINE PRINT PEOPLE THEY ARE SHYSTERS !!!! ) IT NEVER WORKED. Battery dies 3 days after install, receive a used battery, installed battery, still not working. Then told to update the device. What A JOKE. I tried 4 different services on 4 different devices to update this pile of garbage. RUN AWAY FROM THIS DO NOT WASTE $200 OF YOUR MONEY

Works Great!

September16, 2019

I got in on the Kickstarter for Mistbox, with the thought that if it works, great! If it doesn't, I'll survive. After all, every Kickstarter is a gamble. But this one paid off!

I live in Idaho, and we moved into our current home 3 years ago. The A/C unit here is about 20 years old and has a difficult time keeping up with the high temperatures in the summer. When the temps are in the 90's, the A/C may start at 70 in the morning, but it will reach the high 80's by late afternoon. NOT enjoyable at all! Our electricity bill (on "level-pay") were just over $220 per month!

I installed Mistbox lats August 13th and since then, our A/C has no problem keeping the temperature down even on the hottest days. Our electricity bill (again, on "level pay") has dropped to just over $150 per month! That's a $70 per month decrease!

Now, I'm not going to say that the Mistbox is saving us over $800 per year. I don't think it is. But I DO think that it is saving us at least $50 a month for June, July, and August, and $25 a month for April, May, September and October.

In addition, I think that it is extending the life of our A/C unit, as it doesn't have to work nearly as hard, or as long, each day, just to keep the house cool.

If you live someplace hot, like Idaho, I'd say it's well worth the money! I recommend it to all my friends, family, and even to handymen that have dropped by every so often.

If you live somewhere cooler, maybe it won't be as useful. Or if you have a newer A/C unit. But, then, maybe it will extend the life of yours as well. I have no idea. But for me, anything that gives me a few more months/years before I have to spend $1,000 to replace my A/C unit is a good thing right now.
