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 buy. And for good reason. It figures out 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 gone and can raise and lower 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 wise idea to check the Nest thermostat compatibility checker before getting one. Don’t forget to check with your energy provider for valuable rebates, as you may be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either wire it yourself or contact a HVAC pro like Breathe Healthier Air. If you’re wiring it on your own, you’ll see 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 because the thermostat can pull ample power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Issues

The Google Nest Thermostat is an improvement from outdated programmable thermostats that have a combination of wiring and AA batteries for power. It has 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 receive enough power, Nest says you might run into 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, 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, like “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously on, won’t switch on or turns off and on repeatedly in a short period of time.

You might think something is wrong with your heating and cooling system, but if you just installed the Nest, we advise you check your thermostat right away. This is especially pertinent if the weather is mild, and you haven’t been using your heat or air conditioning much.
