The Nest thermostat is one of the best-selling smart thermostats on the market today. And for good reason. It figures out your temperature preferences and develops an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your house or out and about and can raise and lower 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 smart idea to use the Nest thermostat compatibility checker before installing one. Don’t forget to check with your energy company for valuable rebates, since you could be able to get a Nest for free or close to it.

Once you’ve confirmed it’s compatible, you can either hook it up yourself or call a HVAC professional like Air Current AC & Heat. If you’re putting it in yourself, you’ll spot 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. In most cases, Nest says this isn’t a setback because the thermostat can get ample power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Issues

The Google Nest Thermostat is a step up from outdated programmable thermostats that rely on a combination of wiring and AA batteries for power.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 operate your heating and cooling system.

8 Common Nest Thermostat Issues

If it can’t get enough juice, Nest says you may encounter some of these problems:

  1. Poor battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t shut off.
  5. Your system is creating odd 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, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly running, won’t run or turns off and on repeatedly in a short period of time.

You could think something is up with your heating and cooling system, but if you just got the Nest, it’s best to check your thermostat initially. This is especially timely if the weather is moderate, and you haven’t been relying on your heat or air conditioning much.
