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 buy. And for good reason. It figures out your temperature preferences and creates an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E realize when you’re at your home or out and about and can adjust temperatures 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 good idea to visit 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 made sure it’s compatible, you can either wire it without help or contact a HVAC specialist like Central Air LLC. If you’re installing it 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 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 because the thermostat can pull enough power from other heating and cooling wires.

Sometimes, your heating and cooling system could require that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Problems

The Google Nest Thermostat is an improvement 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 operate your heating and cooling system.

8 Common Nest Thermostat Issues

If it can’t draw adequate electricity, Nest says you could run into some of these problems:

  1. Bad battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t turn off.
  5. Your system is producing weird noises, like chattering, stuttering, clicking or thumping.
  6. Heating or cooling is short cycling, or constantly 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 working, won’t switch on or turns off and on frequently in a short period of time.

You could think something is wrong with your heating and cooling system, but if you just got the Nest, we advise you begin with your thermostat initially. This is especially timely if the weather is mild, and you haven’t been relying on your heat or air conditioning much.
