The Nest thermostat is one of the best-selling smart thermostats on the market today. 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 realize when you’re at your home or gone and can change settings to help you save even more.

The Nest is compatible with a full range of 24-volt heating and cooling systems, but it’s always a good idea to visit the Nest thermostat compatibility checker before getting one. Don’t forget to talk with your energy supplier for valuable rebates, because you might 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 on your own or hire a HVAC specialist like Service Max Heating & Air Conditioning. If you’re installing it without help, you’ll spot a terminal for the C-wire, or common wire. This wire is only 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 an issue since the thermostat can pull enough power from other heating and cooling wires.

In some instances, your heating and cooling system could 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 rely on a combination of wiring and AA batteries for power. It uses a rechargeable lithium-ion battery and wiring to link to Wi-Fi, power its digital display and operate your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t draw adequate power, Nest says you could have some of these issues:

  1. Poor battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t turn off.
  5. Your system is producing odd noises, such as 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 notice on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is always on, won’t switch on or turns off and on frequently in a short period of time.

You may worry something is wrong with your heating and cooling system, but if you just got the Nest, it’s best to check your thermostat first. This is especially true if the weather is temperate, and you haven’t been using your heat or air conditioning frequently.
