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 makes an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your house or away and can change temps to help you save even more.

The Nest is compatible with a vast range of 24-volt heating and cooling systems, but it’s always a smart idea to use the Nest thermostat compatibility checker before purchasing one. Don’t forget to talk with your energy provider 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 without help or call a HVAC pro like Air Current AC & Heat. If you’re putting it in on your own, you’ll see 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 most cases, Nest says this isn’t a setback as the thermostat can pull ample power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is an improvement from older programmable thermostats that have a combination of wiring and AA batteries for power. It relies on a rechargeable lithium-ion battery and wiring to sync with Wi-Fi, power its digital display and operate your heating and cooling system.

8 Common Nest Thermostat Malfunctions

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

  1. Short battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t turn off.
  5. Your system is creating 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, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly on, won’t turn on or turns off and on repeatedly in a short period of time.

You could worry something is suspect with your heating and cooling system, but if you just got the Nest, it’s best to check your thermostat initially. This is especially true if the weather is moderate, and you haven’t been relying on your heat or air conditioning frequently.
