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

April 13, 2021

The Nest thermostat is one of the most popular smart thermostats you can get. 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 home or out and about and can change temps to help you save even more.

The Nest is compatible with a vast 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 company for valuable rebates, because you may 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 without help or contact a HVAC specialist like Bell Air Conditioning Inc. If you’re installing it on your own, you’ll see 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 a setback because the thermostat can draw ample 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 better than older 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 run your heating and cooling system.

8 Common Nest Thermostat Problems

If it can’t get adequate juice, Nest says you could encounter some of these problems:

  1. Short battery life.
  2. Thermostat motion sensing won’t work.
  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 making odd noises, like 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 message on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly running, won’t run or turns off and on frequently in a short period of time.

You could think something is suspect with your heating and cooling system, but if you just got the Nest, we advise you start with your thermostat initially. This is especially pertinent if the weather is temperate, and you haven’t been using your heat or air conditioning much.
