If you buy a QuietCool fan, do yourself a favor and spend a little extra more, and buy this remote unit. It works flawlessly, and saves you from having to drill down through your wall, installing an electrical box, and running multiple lengths of Romex between the hardwired timer and switch you would have to purchase separately anyway. The remote unit takes about ten minutes to install on the fan. It takes another two or three minutes to pair the remote control with the remote unit. That's it. That's ALL. It takes all of the electrical voodoo out of installing the fan.I have only one minor gripe with the remote control. There's no "on/off" function; just a high-medium-low button, and a timer button, which gives you the choice of 1, 2, 4, 8, or 12 hours of run time. To turn the fan on, you have to push either button once to wake the remote up. Then you have to pick a fan speed, and then choose the amount of run time. To turn the fan off, you need to toggle through all of the time choices until all of the LED's above the numbers go out. That's how you shut it off. It's klunky. That being said, it takes about two minutes to figure out and put into practice. It's worth putting up with though, given the time it saves when setting up the fan, and the ability to take the remote with you anywhere in the house.As for the fan, I live in the desert. I turn the fan on in the early morning and in the evening to cool the house down. The fan does exactly that. After the house is cool, I close the house up. The average highs for June, 2020 and June 2019 were within a degree of each other. The A/C ran for a total of 6 hours last June, and 3.5 hours this June, as recorded by my Nest thermostat. I don't regret buying the fan one bit. If you need a whole-house fan, you will LOVE the QuietCool fan!
