The Nest thermostat is one of the best-selling smart thermostats you can get. And for good reason. It picks up on your temperature preferences and creates an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your house or gone and can adjust temps to help you save even more.
The Nest can be used with a full range of 24-volt heating and cooling systems, but it’s always a good idea to check the Nest thermostat compatibility checker before getting one. Don’t forget to check with your energy supplier for valuable rebates, because you might be able to get a Nest for free or close to it.
Once you’ve confirmed it’s compatible, you can either hook it up without help or call a HVAC specialist like US Air Heating and Cooling. If you’re putting it in on your own, you’ll see a terminal for the C-wire, or common wire. This wire is only used for powering your thermostat. If your house or HVAC system is older, you might not have one of these wires. Most of the time, Nest says this isn’t a problem because the thermostat can pull ample power from other heating and cooling wires.
In some instances, your heating and cooling system could require that C-wire. And here’s why.
Why Your Nest Keeps Losing Power and Other Problems
The Google Nest Thermostat is better than aging programmable thermostats that rely on a combination of wiring and AA batteries for power. It relies on a rechargeable lithium-ion battery and wiring to connect to Wi-Fi, power its digital display and operate your heating and cooling system.
8 Common Nest Thermostat Issues
If it can’t receive adequate power, Nest says you might run into some of these problems:
- Poor battery life.
- Thermostat motion sensing won’t work.
- Your thermostat every now and then disconnects from Wi-Fi.
- Your system abruptly turns on or off, or won’t turn off.
- Your system is creating odd noises, such as chattering, stuttering, clicking or thumping.
- Heating or cooling is short cycling, or constantly turning on and off in a short period of time.
- There is a delay notification on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
- The system fan is always running, won’t run or turns off and on frequently in a short period of time.
You could think something is wrong with your heating and cooling system, but if you just installed the Nest, we advise you begin with your thermostat right away. This is especially true if the weather is temperate, and you haven’t been relying on your heat or air conditioning much.
