The Nest thermostat is one of the most popular smart thermostats on the market today. And for good reason. It learns your temperature preferences and develops an energy-efficient schedule to match. And by geofencing with your phone, the Nest Learning Thermostat and Nest E realize when you’re at your home or away and can change temps 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 check the Nest thermostat compatibility checker before purchasing one. Don’t forget to talk with your energy company for valuable rebates, because you may be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either wire it on your own or contact a HVAC professional like Phelps Heating & Cooling, Inc.. If you’re putting it in yourself, you’ll spot 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 most cases, Nest says this isn’t a setback because the thermostat can pull enough power from other heating and cooling wires.

In some cases, your heating and cooling system may need that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Issues

The Google Nest Thermostat is better than outdated programmable thermostats that have a combination of wiring and AA batteries for power. It has a rechargeable lithium-ion battery and wiring to connect to Wi-Fi, power its digital display and operate your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t get enough electricity, Nest says you might have 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 turn off.
  5. Your system is producing weird 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 message on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously on, won’t run or turns off and on frequently in a short period of time.

You may believe something is suspect with your heating and cooling system, but if you just got the Nest, we recommend you check your thermostat right away. This is especially true if the weather is moderate, and you haven’t been running your heat or air conditioning consistently.
