Why Your Nest Thermostat Isn't Working and How to Repair It

April 13, 2021

The Nest thermostat is one of the top-selling smart thermostats you can buy. 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 are aware of when you’re at your house or out and about and can change 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 wise idea to visit the Nest thermostat compatibility checker before getting 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 made sure it’s compatible, you can either wire it without help or call a HVAC specialist like Uptown Heating & Cooling. If you’re wiring it without help, you’ll see a terminal for the C-wire, or common wire. This wire is only 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 an issue because the thermostat can draw adequate power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Problems

The Google Nest Thermostat is a step up from outdated programmable thermostats that rely on a combination of wiring and AA batteries for power. It relies on 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 Issues

If it can’t receive ample power, Nest says you could experience some of these problems:

  1. Short battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t turn off.
  5. Your system is producing odd noises, such as 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 notice on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is always running, won’t switch on or turns off and on frequently in a short period of time.

You might think something is up with your heating and cooling system, but if you just installed the Nest, we suggest you start with your thermostat initially. This is especially pertinent if the weather is mild, and you haven’t been using your heat or air conditioning much.
