Why Your Nest Thermostat Isn't Operating Right and How to Solve the Problem

April 13, 2021

The Nest thermostat is one of the best-selling smart thermostats you can get. And for good reason. It figures out your temperature preferences and makes 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 residence or gone and can adjust 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 contact your energy provider for valuable rebates, because you could be able to get a Nest for free or close to it.

Once you’ve confirmed it’s compatible, you can either wire it without help or hire a HVAC pro like HCE Systems Inc. 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 most cases, Nest says this isn’t an issue as the thermostat can pull ample power from other heating and cooling wires.

Sometimes, your heating and cooling system could require 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 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 run your heating and cooling system.

8 Common Nest Thermostat Malfunctions

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

  1. Bad battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t stop running.
  5. Your system is producing odd 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 continuously running, won’t turn on or turns off and on frequently in a short period of time.

You might think something is up with your heating and cooling system, but if you just installed the Nest, it’s best to start with your thermostat first. This is especially pertinent if the weather is temperate, and you haven’t been running your heat or air conditioning frequently.
