Why Your Nest Thermostat Isn't Operating Right and How to Fix It

April 13, 2021

The Nest thermostat is one of the most popular smart thermostats on the market today. And for good reason. It picks up on your temperature preferences and creates an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E realize when you’re at your residence or gone and can change temperatures 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 visit the Nest thermostat compatibility checker before installing one. Don’t forget to check with your energy provider for valuable rebates, since you could be able to get a Nest for free or close to it.

Once you’ve confirmed it’s compatible, you can either install it on your own or call a HVAC pro like SchagrinGAS Company. If you’re installing it without help, you’ll see a terminal for the C-wire, or common wire. This wire is just 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 problem because the thermostat can pull adequate power from other heating and cooling wires.

In some instances, your heating and cooling system could require 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The Google Nest Thermostat is a step up from outdated programmable thermostats that use a combination of wiring and AA batteries for power.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 turn on your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t receive ample juice, Nest says you may have some of these issues:

  1. Poor battery life.
  2. Thermostat motion sensing is disabled.
  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, like “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly running, won’t run or turns off and on rapidly in a short period of time.

You could believe something is wrong with your heating and cooling system, but if you just started using the Nest, we recommend you check your thermostat first. This is especially timely if the weather is temperate, and you haven’t been relying on your heat or air conditioning frequently.
