The Nest thermostat is one of the top-selling smart thermostats you can get. And for good reason. It learns your temperature preferences and makes an energy-efficient schedule to match. And using geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your home or away and can raise and lower settings to help you save even more.

The Nest works 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 installing one. Don’t forget to talk with your energy supplier for valuable rebates, as you might be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either hook it up on your own or contact a HVAC professional like Bell Air Conditioning Inc. If you’re installing it yourself, 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 since the thermostat can draw enough power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is a step up from older 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 sync with Wi-Fi, power its digital display and run your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t get ample electricity, Nest says you could encounter some of these problems:

  1. Short battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t stop running.
  5. Your system is creating weird noises, including 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 message on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly on, won’t turn on or turns off and on frequently in a short period of time.

You could think something is suspect with your heating and cooling system, but if you just installed the Nest, we recommend you begin with your thermostat first. This is especially timely if the weather is mild, and you haven’t been running your heat or air conditioning much.
