The Nest thermostat is one of the most popular smart thermostats you can buy. And for good reason. It learns your temperature preferences and makes 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 out and about and can change temps to help you save even more.

The Nest is compatible with a wide range of 24-volt heating and cooling systems, but it’s always a wise idea to use the Nest thermostat compatibility checker before installing one. Don’t forget to check with your energy company for valuable rebates, because you could be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either install it without help or hire a HVAC specialist like Siloam Springs Heating & AC. If you’re installing it yourself, you’ll spot a terminal for the C-wire, or common wire. This wire is just used for powering your thermostat. If your home or HVAC system is older, you might not have one of these wires. Most of the time, Nest says this isn’t a problem since the thermostat can get ample power from other heating and cooling wires.

In some instances, your heating and cooling system might require that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Issues

The Google Nest Thermostat is a step up from aging programmable thermostats that have a combination of wiring and AA batteries for power. It relies on a rechargeable lithium-ion battery and wiring to link to Wi-Fi, power its digital display and turn on your heating and cooling system.

8 Common Nest Thermostat Issues

If it can’t receive enough electricity, Nest says you could encounter some of these issues:

  1. Poor battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t shut off.
  5. Your system is producing strange noises, like chattering, stuttering, clicking or thumping.
  6. Heating or cooling is short cycling, or repeatedly turning on and off in a short period of time.
  7. There is a delay notice on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is always on, won’t switch on or turns off and on rapidly in a short period of time.

You could believe something is suspect with your heating and cooling system, but if you just got the Nest, we suggest you start with your thermostat right away. This is especially true if the weather is mild, and you haven’t been running your heat or air conditioning consistently.
