Why Your Nest Thermostat Isn't Operating 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 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 are aware of when you’re at your home or away and can adjust temperatures 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 check the Nest thermostat compatibility checker before purchasing one. Don’t forget to contact your energy supplier for valuable rebates, since 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 wire it without help or contact a HVAC professional like LTS Plumbing & Heating Inc.. If you’re putting it in without help, 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 most cases, Nest says this isn’t a problem because the thermostat can pull ample power from other heating and cooling wires.

In some instances, your heating and cooling system could have to have 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 rely on 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 run your heating and cooling system.

8 Common Nest Thermostat Problems

If it can’t get enough juice, Nest says you could run into some of these problems:

  1. Bad battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t turn off.
  5. Your system is producing weird noises, such as 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 message on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly on, won’t switch on or turns off and on rapidly in a short period of time.

You might worry something is up with your heating and cooling system, but if you just installed the Nest, we recommend you begin with your thermostat right away. This is especially pertinent if the weather is moderate, and you haven’t been running your heat or air conditioning frequently.
