The Nest thermostat is one of the top-selling smart thermostats on the market today. And for good reason. It learns your temperature preferences and develops an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E realize when you’re at your house or out and about and can adjust 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 good idea to visit the Nest thermostat compatibility checker before purchasing one. Don’t forget to check with your energy supplier for valuable rebates, since you could 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 specialist like Covington Air Systems. If you’re installing it yourself, 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. Most of the time, Nest says this isn’t a problem as the thermostat can get adequate power from other heating and cooling wires.

In some instances, your heating and cooling system might have to have that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Issues

The Google Nest Thermostat is an improvement from older programmable thermostats that have 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 operate your heating and cooling system.

8 Common Nest Thermostat Malfunctions

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

  1. Poor battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system suddenly 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 constantly turning on and off in a short period of time.
  7. There is a delay notice on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly working, won’t turn on or turns off and on repeatedly in a short period of time.

You could believe something is up with your heating and cooling system, but if you just installed the Nest, we recommend you start with your thermostat first. This is especially true if the weather is temperate, and you haven’t been using your heat or air conditioning much.
