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

April 13, 2021

The Nest thermostat is one of the most popular smart thermostats on the market today. And for good reason. It learns your temperature preferences and makes 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 out and about and can raise and lower settings to help you save even more.

The Nest works with a vast range of 24-volt heating and cooling systems, but it’s always a smart idea to visit the Nest thermostat compatibility checker before getting one. Don’t forget to check with your energy provider for valuable rebates, because you may 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 on your own or call a HVAC pro like Air Alliance Team. If you’re installing it 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 residence or HVAC system is older, you might not have one of these wires. In most cases, Nest says this isn’t a problem since the thermostat can get adequate power from other heating and cooling wires.

In some cases, your heating and cooling system might require that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is better than older programmable thermostats that rely on 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 Issues

If it can’t draw enough electricity, Nest says you may experience some of these problems:

  1. Bad battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t stop running.
  5. Your system is producing odd noises, including 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, like “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously working, won’t run or turns off and on frequently in a short period of time.

You could think something is up with your heating and cooling system, but if you just got the Nest, we suggest you begin with your thermostat initially. This is especially pertinent if the weather is moderate, and you haven’t been using your heat or air conditioning consistently.
