Nest Thermostat and Airwave(TM) technology

sbillerApril 5, 2012

Nest Labs released a software update to their learning thermostat today that includes a feature called Airwave.

Airwave automatically switches off your air conditioner a few minutes early, since your AC continues to make cold air for 5-10 minutes after it's off. Then Airwave uses the fan to spread the cool air through your home.

This Nest exclusive can save up to 30% on your cooling costs.

Is this truly a unique feature and will it really save me on my air condition bill in Florida?

You must have a magic coil there. I tried low-speed fan as an experiment. The air out of the register turned warm and dank very quickly.

The fan probably runs a minute or so after compressor shuts off. After that, the low-speed fan takes over. Quickly disabled that feature/.

Maybe helps a little in arid climates. In any kind of humidity, don't even think about it.

The claim is up to a 30% savings by turning off the compressor a few minutes early. I think savings would be closer to 3% than 30%.

To be fair I think their claim is to save 30% by all the features, not just this early shutoff. I've heard about this stat and it's supposed to "learn" your home/away patterns to use minimal energy. Wouldn't work for me as we often have completely random home/away hours. I prefer to program something and have it work as I expect I don't want it trying to make decisions for me.

Seems pretty clear from the web site I've linked that they are claiming 30% savings from Airwave alone.

What is Airwave?
Airwave�, an exclusive feature of the Nest Learning Thermostat, can automatically lower air-conditioning costs up to 30%. Airwave only works in homes that have air-conditioning.
