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

April 13, 2021

The Nest thermostat is one of the best-selling 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 know when you’re at your home or away and can adjust temperatures to help you save even more.

The Nest works with a wide range of 24-volt heating and cooling systems, but it’s always a smart idea to visit the Nest thermostat compatibility checker before getting one. Don’t forget to contact your energy provider for valuable rebates, since you might be able to get a Nest for free or close to it.

Once you’ve made sure it’s compatible, you can either wire it on your own or contact a HVAC pro like Air Concepts of Middle Georgia. If you’re installing it yourself, you’ll see a terminal for the C-wire, or common wire. This wire is solely 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 draw adequate power from other heating and cooling wires.

In some cases, your heating and cooling system could need 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 have a combination of wiring and AA batteries for power. It uses a rechargeable lithium-ion battery and wiring to connect to Wi-Fi, power its digital display and run your heating and cooling system.

8 Common Nest Thermostat Issues

If it can’t draw ample electricity, Nest says you could have some of these troubles:

  1. Short battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t turn off.
  5. Your system is producing strange noises, including 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 notification 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 might worry something is suspect with your heating and cooling system, but if you just started using the Nest, we suggest you start with your thermostat first. This is especially true if the weather is moderate, and you haven’t been relying on your heat or air conditioning frequently.
