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

April 13, 2021

The Nest thermostat is one of the top-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 know when you’re at your home or out and about and can raise and lower temps to help you save even more.

The Nest can be used with a vast range of 24-volt heating and cooling systems, but it’s always a wise idea to use the Nest thermostat compatibility checker before purchasing one. Don’t forget to check with your energy provider for valuable rebates, since you could be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either hook it up yourself or call a HVAC pro like Rapids Sheet Metal Works Inc. 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 house or HVAC system is older, you might not have one of these wires. Most of the time, Nest says this isn’t a problem as the thermostat can get adequate power from other heating and cooling wires.

In some instances, your heating and cooling system might have to have 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The Google Nest Thermostat is an improvement from outdated programmable thermostats that have a combination of wiring and AA batteries for power.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 uses a rechargeable lithium-ion battery and wiring to connect to Wi-Fi, power its digital display and operate your heating and cooling system.

8 Common Nest Thermostat Issues

If it can’t receive enough juice, Nest says you may run into some of these troubles:

  1. Poor battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t stop running.
  5. Your system is producing weird noises, including 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 notification on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly working, won’t run or turns off and on frequently in a short period of time.

You may think something is wrong with your heating and cooling system, but if you just started using the Nest, we recommend you start with your thermostat first. This is especially timely if the weather is temperate, and you haven’t been running your heat or air conditioning much.
