Anyone can install a CoolBot! It takes 2-3 minutes.
No tools are required except your fingers.
No permanent modifications are made to the a/c units. There is no cutting or splicing of anything.
Detailed instructions with pictures as well as a toll-free support number come with your order.
Here's a YouTube video I made of me installing a CoolBot on the air-conditioner in our farm cooler. Even talking through it, it only takes a few minutes.

**This video was made before 2013, when we still loved LGs. We no longer recommend them. Please see our A/C Size and Brand Recommendation page for our current recommendations.**
Here's a run-down of the steps required to install the CoolBot with your...
- Install any brand of window A/C unit which you've purchased separately. (See our A/C Size and Brand Recommendation to make sure you have the right air conditioner for your space) We just cut a sloppy hole in the wall of our home-built walk-in cooler with a chain saw, stuffed the A/C unit into the hole, and then used "Great Stuff" foam sealant (From Home Depot or Lowes) to seal up the gaps. **We have learned, that it is better to use some type of insulation, like foam sleeves for pipes, so that you can easily remove the a/c instead of having to carve it out.**
- Plug the CoolBot into a standard A/C outlet - it uses no more electricity to run than a cell-phone charger, so no special electrical connections are needed.
- There are three labeled wires coming out of CoolBot: The first (labelled "ROOM") measures the temperature of the room. Just let it hang free, be sure it is not making contact with any metal and not in the direct pathway of the cold air.
- The second wire (labeled "FIN Sensor") you stick into the front cooling fins of the A/C unit. This needs to be as low as possible, but ABOVE the first horizontal cooling tube. Use a pen or pencil to widen a space 1-2 inches up from the bottom and put the fin sensor 1/3 of an inch in so it is not touching the coolant pipes behind them. It stays there on its own. No tape or screws.
- The third wire (labeled "HEATER") attaches to the temperature sensor you see stuck to the front fins of your air-conditioner. (It's the only thing you'll see attached to the front fins of your A/C unit, so no guessing necessary!) Just wrap the CoolBot "HEATER" wire up with that air-conditioner temperature sensor using a small 1/2 inch by 1 inch piece of aluminum foil (included) to ensure a good thermal connection. Allow this foil pack to hang freely away from any metal or in the direct pathway of cold air.
- The CoolBot comes pre-programmed to cool your room down to 41 F (5 C), but you can set it to whatever you want. Click here for more information on how to program your CoolBot.
Here is a video of Ron illustrating how to remove the panel and disengage the secondary sensor
If you have a GE Window Unit that is over 12,000 BTU, most Kenmores, Arctic King, most Frigidaires, Comfortaire, Soleus, Black and Decker or Danby there will be a Secondary Sensor! This must be disengaged in order to work properly.
Look straight down from your air conditioner control panel area to the SIDE of the front fins. You'll see silver or copper colored coolant pipes. Look for a temperature sensor attached to the lowest or second lowest “U” of the coolant pipe. It could be attached with a plastic wire-tie, but usually it's stuck in a little copper cup welded onto the pipe. The sensor slips OUT of the sleeve. We use a “not-sharp” knife. Don't cut the sensor! You might have to cut some plastic ties holding it in place.
**On SOME a/c units (like GE units >15,000 BTU's) you can't see the coils until you remove the plastic cover, such is the case with the a/c pictured below. The person had to unscrew four screws to get it off and then it "POPPED" off with a flat-head screwdriver (which was apparently scary for them, but it doesn't hurt or crack anything). They then chose to keep it removed and attached their control panel to the neighboring wall.
Here is a picture of that secondary sensor if its behind the second panel:
And a close up of what it looks like:
Above 36F, just let the secondary sensor hang free outside the body of the a/c unit so it doesn't touch anything metal. BELOW 36F, use just 2 layers of electrical tape to attach the tip end of the secondary sensor to the OUTSIDE of the aluminum foil combination.
