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

April 13, 2021

The Nest thermostat is one of the top-selling smart thermostats on the market today. And for good reason. It figures out your temperature preferences and develops 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 home or gone and can adjust 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 good idea to check the Nest thermostat compatibility checker before installing one. Don’t forget to talk 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 made sure it’s compatible, you can either install it yourself or call a HVAC specialist like Rescue Heating & Air . If you’re wiring 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 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 enough power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Problems

The Google Nest Thermostat is an improvement from older programmable thermostats that rely on a combination of wiring and AA batteries for power. It uses a rechargeable lithium-ion battery and wiring to link 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 may experience some of these troubles:

  1. Bad battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t turn off.
  5. Your system is creating weird noises, including chattering, stuttering, clicking or thumping.
  6. Heating or cooling is short cycling, or frequently turning on and off in a short period of time.
  7. There is a delay notification on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously on, won’t turn on or turns off and on rapidly in a short period of time.

You could worry something is up with your heating and cooling system, but if you just started using the Nest, we recommend you begin with your thermostat right away. This is especially timely if the weather is moderate, and you haven’t been using your heat or air conditioning much.
