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

April 13, 2021

The Nest thermostat is one of the best-selling smart thermostats you can get. And for good reason. It picks up on your temperature preferences and develops an energy-efficient schedule to match. And by geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your residence or out and about and can raise and lower settings 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 smart idea to use the Nest thermostat compatibility checker before getting one. Don’t forget to check with your energy supplier 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 install it yourself or hire a HVAC professional like Home Comfort Heating & Air. If you’re installing it without help, you’ll notice 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. In the majority of cases, Nest says this isn’t a problem because the thermostat can draw ample power from other heating and cooling wires.

Sometimes, 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 an improvement from 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 Problems

If it can’t draw ample juice, Nest says you might encounter some of these troubles:

  1. Bad battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t stop running.
  5. Your system is creating 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, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is always running, won’t turn on or turns off and on frequently in a short period of time.

You could worry something is wrong with your heating and cooling system, but if you just got the Nest, it’s best to begin with your thermostat initially. This is especially true if the weather is mild, and you haven’t been running your heat or air conditioning much.
