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 you can buy. And for good reason. It learns your temperature preferences and creates an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your residence or away and can raise and lower temperatures to help you save even more.

The Nest is compatible with a wide range of 24-volt heating and cooling systems, but it’s always a good idea to use the Nest thermostat compatibility checker before purchasing one. Don’t forget to contact your energy supplier for valuable rebates, because you may be able to get a Nest for free or close to it.

Once you’ve confirmed it’s compatible, you can either hook it up without help or contact a HVAC specialist like Scott Temperature. If you’re installing it without help, 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. Most of the time, Nest says this isn’t an issue as the thermostat can draw adequate power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Problems

The Google Nest Thermostat is a step up from older programmable thermostats that rely on a combination of wiring and AA batteries for power. It relies on a rechargeable lithium-ion battery and wiring to connect to Wi-Fi, power its digital display and turn on your heating and cooling system.

8 Common Nest Thermostat Problems

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

  1. Poor battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t shut off.
  5. Your system is creating odd noises, like 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 notification on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously working, won’t turn on or turns off and on repeatedly in a short period of time.

You may think something is suspect with your heating and cooling system, but if you just installed the Nest, we suggest you start with your thermostat right away. This is especially true if the weather is mild, and you haven’t been using your heat or air conditioning much.
