The Nest thermostat is one of the best-selling smart thermostats you can buy. And for good reason. It figures out 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 away and can change settings 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 good idea to check the Nest thermostat compatibility checker before purchasing one. Don’t forget to check with your energy supplier for valuable rebates, because you could be able to get a Nest for free or close to it.

Once you’ve made sure it’s compatible, you can either hook it up without help or call a HVAC professional like Mountain Air. If you’re installing it without help, you’ll notice a terminal for the C-wire, or common wire. This wire is only used for powering your thermostat. If your home 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 as the thermostat can pull adequate power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is better than older programmable thermostats that rely on a combination of wiring and AA batteries for power. It has a rechargeable lithium-ion battery and wiring to link to Wi-Fi, power its digital display and run your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t receive ample juice, Nest says you could have some of these issues:

  1. Poor battery life.
  2. Thermostat motion sensing is disabled.
  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 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 notification 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 rapidly in a short period of time.

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