The Nest thermostat is one of the best-selling smart thermostats you can buy. And for good reason. It learns your temperature preferences and develops an energy-efficient schedule to match. And by geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your home or gone and can change settings to help you save even more.

The Nest can be used with a vast range of 24-volt heating and cooling systems, but it’s always a wise idea to visit the Nest thermostat compatibility checker before purchasing one. Don’t forget to contact your energy company for valuable rebates, as you could 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 on your own or call a HVAC pro like JTech Mechanical. If you’re installing it yourself, you’ll spot a terminal for the C-wire, or common wire. This wire is solely used for powering your thermostat. If your residence or HVAC system is older, you might not have one of these wires. In the majority of cases, Nest says this isn’t a setback since the thermostat can draw ample power from other heating and cooling wires.

Sometimes, your heating and cooling system may need that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Issues

The Google Nest Thermostat is an improvement from aging programmable thermostats that use 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 turn on your heating and cooling system.

8 Common Nest Thermostat Issues

If it can’t receive enough power, Nest says you might run into some of these troubles:

  1. Short battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t shut off.
  5. Your system is producing odd noises, like chattering, stuttering, clicking or thumping.
  6. Heating or cooling is short cycling, or frequently turning on and off in a short period of time.
  7. There is a delay notification on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously running, won’t run or turns off and on rapidly in a short period of time.

You could believe something is up with your heating and cooling system, but if you just installed the Nest, we suggest you check your thermostat initially. This is especially true if the weather is mild, and you haven’t been relying on your heat or air conditioning frequently.
