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

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 develops 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 residence or out and about and can change 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 wise idea to check the Nest thermostat compatibility checker before getting one. Don’t forget to talk with your energy company for valuable rebates, as 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 wire it without help or call a HVAC specialist like Franklin's Heating & Air Conditioning, Inc. If you’re putting it in on your own, you’ll notice a terminal for the C-wire, or common wire. This wire is solely 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 a setback because the thermostat can draw enough 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The Google Nest Thermostat is better than outdated programmable thermostats that have a combination of wiring and AA batteries for power. It relies on 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 draw ample power, Nest says you could have some of these troubles:

  1. Short battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t stop running.
  5. Your system is creating strange 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 notice on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is always running, won’t switch on or turns off and on rapidly in a short period of time.

You may believe something is up with your heating and cooling system, but if you just got the Nest, it’s best to 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 consistently.
