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

April 13, 2021

The Nest thermostat is one of the best-selling smart thermostats you can buy. And for good reason. It learns your temperature preferences and makes 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 home or gone and can raise and lower 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 smart idea to use the Nest thermostat compatibility checker before purchasing one. Don’t forget to check with your energy company for valuable rebates, since 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 contact a HVAC professional like Brooks Heating and Air Conditioning. If you’re installing it on your own, you’ll see a terminal for the C-wire, or common wire. This wire is just used for powering your thermostat. If your home or HVAC system is older, you might not have one of these wires. Most of the time, Nest says this isn’t a setback since the thermostat can draw enough power from other heating and cooling wires.

In some cases, your heating and cooling system may need that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Issues

The Google Nest Thermostat is an improvement from outdated programmable thermostats that use a combination of wiring and AA batteries for power. It has 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 Issues

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

  1. Poor battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system suddenly 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 repeatedly turning on and off in a short period of time.
  7. There is a delay notification on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is always working, won’t turn on or turns off and on frequently in a short period of time.

You could believe something is wrong with your heating and cooling system, but if you just started using the Nest, it’s best to check your thermostat first. This is especially timely if the weather is mild, and you haven’t been running your heat or air conditioning much.
