The Nest thermostat is one of the top-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 by geofencing with your phone, the Nest Learning Thermostat and Nest E realize when you’re at your house or away and can change settings to help you save even more.

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

Once you’ve confirmed it’s compatible, you can either wire it on your own or hire a HVAC specialist like Morgner Inc. Air Conditioning & Heating. If you’re putting it in on your own, you’ll see a terminal for the C-wire, or common wire. This wire is just 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 pull ample 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 Problems

The Google Nest Thermostat is a step up from outdated programmable thermostats that use a combination of wiring and AA batteries for power. It uses 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 Issues

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

  1. Bad battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t stop running.
  5. Your system is creating strange 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 notification on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
  8. The system fan is always running, won’t turn on or turns off and on frequently in a short period of time.

You may believe something is suspect with your heating and cooling system, but if you just got the Nest, we recommend you check your thermostat right away. This is especially timely if the weather is temperate, and you haven’t been using your heat or air conditioning consistently.
