The Nest thermostat is one of the best-selling smart thermostats you can get. And for good reason. It learns your temperature preferences and makes an energy-efficient schedule to match. And by geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your residence or gone and can raise and lower temps 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 visit the Nest thermostat compatibility checker before installing one. Don’t forget to talk with your energy provider for valuable rebates, since 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 call a HVAC pro like House of Heating Incorporated. If you’re installing it on your own, you’ll spot 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 problem because the thermostat can draw 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 Problems

The Google Nest Thermostat is a step up from older 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 run your heating and cooling system.

8 Common Nest Thermostat Issues

If it can’t draw enough electricity, Nest says you may run into some of these issues:

  1. Bad battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t shut off.
  5. Your system is creating weird 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 notice on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly on, 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 installed the Nest, it’s best to check your thermostat first. This is especially pertinent if the weather is temperate, and you haven’t been running your heat or air conditioning much.
