The Nest thermostat is one of the best-selling smart thermostats you can get. And for good reason. It learns your temperature preferences and develops 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 house or gone and can change temps 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 getting one. Don’t forget to contact your energy supplier for valuable rebates, because you may be able to get a Nest for free or close to it.

Once you’ve confirmed it’s compatible, you can either install it yourself or hire a HVAC specialist like AZ Air Conditioning and Heating. If you’re putting it in yourself, you’ll see 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 the majority of cases, Nest says this isn’t a problem because the thermostat can pull ample power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is a step up 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 Issues

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

  1. Bad 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 making strange noises, including 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, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously running, won’t switch on or turns off and on rapidly in a short period of time.

You may worry something is suspect with your heating and cooling system, but if you just got the Nest, we advise you check your thermostat initially. This is especially pertinent if the weather is moderate, and you haven’t been relying on your heat or air conditioning frequently.
