Why Your Nest Thermostat Isn't Running Right and How to Solve the Problem

April 13, 2021

The Nest thermostat is one of the top-selling smart thermostats on the market today. And for good reason. It learns your temperature preferences and develops an energy-efficient schedule to match. And by geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your house or out and about and can raise and lower temperatures 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 good idea to check 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 hook it up without help or call a HVAC professional like Taylor's Heating & Air Conditioning. If you’re putting it in 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 residence 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 ample power from other heating and cooling wires.

In some instances, your heating and cooling system may have to have that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Issues

The Google Nest Thermostat is a step up from aging programmable thermostats that have a combination of wiring and AA batteries for power. It has a rechargeable lithium-ion battery and wiring to link to Wi-Fi, power its digital display and run your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t draw adequate electricity, Nest says you may run into some of these problems:

  1. Short battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t shut off.
  5. Your system is creating weird noises, like 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 message on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously on, won’t run 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 started using the Nest, we suggest you start with your thermostat first. This is especially timely if the weather is mild, and you haven’t been using your heat or air conditioning consistently.
