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

April 13, 2021

The Nest thermostat is one of the most popular smart thermostats on the market today. And for good reason. It picks up on your temperature preferences and makes an energy-efficient schedule to match. And by geofencing with your phone, the Nest Learning Thermostat and Nest E realize when you’re at your house or out and about and can adjust temps to help you save even more.

The Nest can be used with a full range of 24-volt heating and cooling systems, but it’s always a good idea to visit the Nest thermostat compatibility checker before getting one. Don’t forget to check with your energy supplier 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 install it on your own or hire a HVAC professional like Walter's-Eaton's Electric, Plumbing, Heating & AC. If you’re installing it 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 house or HVAC system is older, you might not have one of these wires. Most of the time, Nest says this isn’t an issue since the thermostat can draw adequate power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is better than aging programmable thermostats that use a combination of wiring and AA batteries for power. It relies on a rechargeable lithium-ion battery and wiring to connect to Wi-Fi, power its digital display and turn on your heating and cooling system.

8 Common Nest Thermostat Malfunctions

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

  1. Bad battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t shut off.
  5. Your system is making 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 working, won’t switch on or turns off and on repeatedly in a short period of time.

You could worry something is up with your heating and cooling system, but if you just installed the Nest, we advise you begin 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.
