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 know when you’re at your residence or gone and can adjust temperatures to help you save even more.

The Nest works with a wide range of 24-volt heating and cooling systems, but it’s always a wise idea to use the Nest thermostat compatibility checker before installing one. Don’t forget to contact your energy provider for valuable rebates, because you may be able to get a Nest for free or close to it.

Once you’ve made sure it’s compatible, you can either wire it yourself or contact a HVAC pro like Cooks Air Conditioning and Heating Specialists. If you’re putting it in yourself, you’ll notice 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. In most cases, Nest says this isn’t a setback because the thermostat can pull adequate power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is an improvement from aging programmable thermostats that use 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 turn on your heating and cooling system.

8 Common Nest Thermostat Problems

If it can’t receive enough electricity, Nest says you might run into some of these troubles:

  1. Poor battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t stop running.
  5. Your system is making weird noises, such as 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 always running, won’t run or turns off and on rapidly in a short period of time.

You may worry something is wrong with your heating and cooling system, but if you just installed the Nest, it’s best to 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 consistently.
