The Nest thermostat is one of the best-selling smart thermostats on the market today. And for good reason. It learns your temperature preferences and creates 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 away and can change temps to help you save even more.

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

Once you’ve checked it’s compatible, you can either install it without help or call a HVAC professional like Bell Mechanical Services. If you’re putting it in without help, you’ll notice a terminal for the C-wire, or common wire. This wire is solely 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 as the thermostat can draw enough power from other heating and cooling wires.

In some cases, your heating and cooling system could 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 aging programmable thermostats that rely on a combination of wiring and AA batteries for power. It uses a rechargeable lithium-ion battery and wiring to connect to Wi-Fi, power its digital display and run your heating and cooling system.

8 Common Nest Thermostat Issues

If it can’t get enough electricity, Nest says you could encounter 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 suddenly turns on or off, or won’t stop running.
  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 message on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously running, won’t run or turns off and on rapidly in a short period of time.

You might think something is up with your heating and cooling system, but if you just started using the Nest, we recommend you start with your thermostat right away. This is especially timely if the weather is mild, and you haven’t been running your heat or air conditioning consistently.
