Why Your Nest Thermostat Isn't Working 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 makes an energy-efficient schedule to match. And using geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your house or gone and can adjust 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 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 might be able to get a Nest for free or close to it.

Once you’ve made sure it’s compatible, you can either hook it up yourself or hire a HVAC pro like Hale's Air Conditioning Services Inc. If you’re wiring it yourself, you’ll spot 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 the majority of cases, Nest says this isn’t a problem as the thermostat can get ample power from other heating and cooling wires.

In some instances, 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The Google Nest Thermostat is an improvement from outdated programmable thermostats that rely on a combination of wiring and AA batteries for power.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 connect to Wi-Fi, power its digital display and operate your heating and cooling system.

8 Common Nest Thermostat Malfunctions

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

  1. Poor battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t shut off.
  5. Your system is creating weird noises, including 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, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is always on, won’t run 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 got the Nest, we recommend you check your thermostat right away. This is especially pertinent if the weather is moderate, and you haven’t been relying on your heat or air conditioning frequently.
