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

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 out and about and can change settings to help you save even more.

The Nest is compatible with a wide range of 24-volt heating and cooling systems, but it’s always a good idea to use the Nest thermostat compatibility checker before getting one. Don’t forget to talk 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 hire a HVAC specialist like Olde Towne Heating & Air. If you’re installing 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 since the thermostat can get adequate 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 better than older programmable thermostats that use a combination of wiring and AA batteries for power. It has a rechargeable lithium-ion battery and wiring to sync with Wi-Fi, power its digital display and operate your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t receive ample electricity, Nest says you might run into some of these problems:

  1. Short battery life.
  2. Thermostat motion sensing won’t work.
  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 producing odd 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 continuously on, won’t turn on or turns off and on repeatedly in a short period of time.

You might think something is suspect with your heating and cooling system, but if you just installed the Nest, we suggest you start with your thermostat first. This is especially timely if the weather is temperate, and you haven’t been relying on your heat or air conditioning much.
