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

April 13, 2021

The Nest thermostat is one of the top-selling smart thermostats you can buy. And for good reason. It figures out your temperature preferences and creates an energy-efficient schedule to match. And using geofencing with your phone, the Nest Learning Thermostat and Nest E realize when you’re at your residence or away and can change temperatures 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 check the Nest thermostat compatibility checker before installing 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 yourself or call a HVAC professional like Keystone Heating & Air Conditioning Co., Inc. If you’re putting it in on your own, you’ll see a terminal for the C-wire, or common wire. This wire is solely used for powering your thermostat. If your residence 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 since the thermostat can get enough power from other heating and cooling wires.

Sometimes, your heating and cooling system might have to have 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 have a combination of wiring and AA batteries for power. It uses 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 get adequate electricity, Nest says you could have some of these issues:

  1. Short battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t turn off.
  5. Your system is making 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 notification on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously working, won’t turn on or turns off and on frequently in a short period of time.

You could think something is suspect with your heating and cooling system, but if you just installed the Nest, it’s best to start with your thermostat first. This is especially pertinent if the weather is moderate, and you haven’t been relying on your heat or air conditioning much.
