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 learns your temperature preferences and creates 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 house or gone and can raise and lower settings 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 wise idea to use the Nest thermostat compatibility checker before installing one. Don’t forget to talk with your energy provider for valuable rebates, since you may be able to get a Nest for free or close to it.

Once you’ve confirmed it’s compatible, you can either hook it up on your own or call a HVAC specialist like American HVAC Inc. If you’re wiring it yourself, you’ll see a terminal for the C-wire, or common wire. This wire is only 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 an issue since the thermostat can draw adequate power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Problems

The Google Nest Thermostat is an improvement 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 operate your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t draw enough electricity, Nest says you could encounter some of these issues:

  1. Poor battery life.
  2. Thermostat motion sensing won’t operate.
  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 producing strange noises, such as 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 notice on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously on, won’t turn on or turns off and on frequently in a short period of time.

You could worry something is suspect with your heating and cooling system, but if you just started using the Nest, it’s best to start with your thermostat right away. This is especially true if the weather is moderate, and you haven’t been using your heat or air conditioning consistently.
