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

April 13, 2021

The Nest thermostat is one of the most popular smart thermostats on the market today. And for good reason. It figures out your temperature preferences and develops an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your home or away and can change temps to help you save even more.

The Nest works with a wide range of 24-volt heating and cooling systems, but it’s always a wise idea to use the Nest thermostat compatibility checker before purchasing one. Don’t forget to contact your energy company for valuable rebates, as you could be able to get a Nest for free or close to it.

Once you’ve confirmed it’s compatible, you can either install it on your own or call a HVAC specialist like Willco Air Conditioning, Refrigeration & Heating Inc.. If you’re putting it in on your own, you’ll notice 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 a problem because the thermostat can draw adequate power from other heating and cooling wires.

In some instances, 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 aging 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 turn on your heating and cooling system.

8 Common Nest Thermostat Problems

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

  1. Poor battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t turn off.
  5. Your system is creating weird 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 message on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously running, won’t run or turns off and on rapidly in a short period of time.

You could think something is up with your heating and cooling system, but if you just installed the Nest, we advise you check your thermostat right away. This is especially true if the weather is moderate, and you haven’t been relying on your heat or air conditioning frequently.
