Can I hook up two thermostats to one furnace?
Regarding this, can you install a second thermostat?
You can help make a more evenly conditioned home by installing a separate thermostat in another part of the house. When two thermostats are wired to a heating or cooling system with a zone control and dampers installed in the ductwork, you have true separate temperature zones in your home.
One may also ask, can two thermostats control one AC unit? It is possible to install a single central air-conditioning unit, with two or more thermostats, that can cool the house equally. Each zone of the house can be turned down or closed off to save energy. The thermostat in each zone controls the temperature in the zone.
Considering this, can you link two Nest thermostats?
The short answer to the questions posed above is: yes. Nest thermostats can certainly be used in conjunction with zoned HVAC systems. However, you are indeed going to require multiple Nest thermostats throughout the house.
Does HVAC zoning save money?
System zoning can save homeowners up to 30 percent on a typical heating and cooling bill, according to the U.S. Department of Energy,. The savings can pay for the cost of installing a zoning system, possibly, within two to five years. There are not many HVAC items that can offer that kind of payback.
