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 learns your temperature preferences and makes an energy-efficient schedule to match. And by geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your house or out and about and can raise and lower temps to help you save even more.

The Nest works 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 purchasing one. Don’t forget to contact your energy provider for valuable rebates, since you may be able to get a Nest for free or close to it.

Once you’ve confirmed it’s compatible, you can either wire it on your own or hire a HVAC pro like Goode Bros AC & Heating. If you’re wiring it on your own, you’ll spot a terminal for the C-wire, or common wire. This wire is just used for powering your thermostat. If your home or HVAC system is older, you might not have one of these wires. In the majority of cases, Nest says this isn’t an issue since the thermostat can draw enough power from other heating and cooling wires.

In some cases, 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 better than aging programmable thermostats that use a combination of wiring and AA batteries for power. It relies on 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 Problems

If it can’t receive adequate juice, Nest says you may run into some of these issues:

  1. Short battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t turn off.
  5. Your system is producing 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 notice on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is always on, won’t run or turns off and on frequently in a short period of time.

You may think something is up with your heating and cooling system, but if you just got the Nest, we recommend you start with your thermostat first. This is especially true if the weather is moderate, and you haven’t been using your heat or air conditioning much.
