Yes, the Nest Airwave can save you a lot of money. Nest smart thermostats have a proprietary feature called the Airwave which they use to reduce your HVAC’s electrical power consumption. This airwave feature instructs your air conditioner to shut its air compressor off, leaving only its fan functioning to circulate air through the cold coil and throughout the room. Once the airwave feature shuts off your HVAC’s compressor prematurely, only the air conditioning fan motor will function. And this reduces the HAVC’s electrical power consumption. This feature comes in handy in summer when there’s an overload on the grid and when power supply companies charge a premium fee. So, you want to activate this Nest thermostat feature to save on your heating and cooling costs.
