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

April 13, 2021

The Nest thermostat is one of the most popular smart thermostats you can get. And for good reason. It picks up on your temperature preferences and creates 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 raise and lower settings to help you save even more.

The Nest is compatible with a full range of 24-volt heating and cooling systems, but it’s always a good idea to use the Nest thermostat compatibility checker before getting one. Don’t forget to talk with your energy provider for valuable rebates, because you could be able to get a Nest for free or close to it.

Once you’ve confirmed it’s compatible, you can either wire it without help or contact a HVAC pro like Paso Robles Heating and Air. If you’re wiring it yourself, you’ll notice 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 a setback since the thermostat can pull enough power from other heating and cooling wires.

In some cases, your heating and cooling system might need 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 older programmable thermostats that have a combination of wiring and AA batteries for power. It has a rechargeable lithium-ion battery and wiring to connect to Wi-Fi, power its digital display and operate your heating and cooling system.

8 Common Nest Thermostat Issues

If it can’t draw enough juice, Nest says you may have some of these issues:

  1. Short battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t shut off.
  5. Your system is creating strange 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 message on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is always on, won’t switch on or turns off and on repeatedly in a short period of time.

You may think something is wrong with your heating and cooling system, but if you just installed the Nest, it’s best to check your thermostat right away. This is especially pertinent if the weather is mild, and you haven’t been relying on your heat or air conditioning frequently.
