The Nest thermostat is one of the top-selling smart thermostats on the market today. And for good reason. It picks up on your temperature preferences and develops an energy-efficient schedule to match. And using geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your house or away and can raise and lower temperatures to help you save even more.

The Nest can be used 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 installing one. Don’t forget to check with your energy company for valuable rebates, since you might 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 on your own or call a HVAC specialist like Central Air LLC. If you’re putting it in yourself, 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. In the majority of cases, Nest says this isn’t a problem since the thermostat can draw ample power from other heating and cooling wires.

Sometimes, your heating and cooling system may have to have that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Problems

The Google Nest Thermostat is an improvement from outdated programmable thermostats that rely on a combination of wiring and AA batteries for power.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 Problems

If it can’t get ample power, Nest says you might run into some of these troubles:

  1. Short 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 shut off.
  5. Your system is creating weird noises, such as 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 always on, won’t run or turns off and on rapidly in a short period of time.

You might worry something is up with your heating and cooling system, but if you just got the Nest, we suggest you check your thermostat right away. This is especially pertinent if the weather is moderate, and you haven’t been relying on your heat or air conditioning much.
