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

April 13, 2021

The Nest thermostat is one of the most popular smart thermostats you can get. 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 are aware of when you’re at your residence or gone and can adjust temperatures to help you save even more.

The Nest is compatible 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 installing one. Don’t forget to check with your energy provider for valuable rebates, since you may be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either install it on your own or call a HVAC pro like Hix Air Conditioning Service, Inc.. If you’re putting it in yourself, you’ll see a terminal for the C-wire, or common wire. This wire is solely used for powering your thermostat. If your home or HVAC system is older, you might not have one of these wires. In most cases, Nest says this isn’t a setback because the thermostat can pull adequate 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 Issues

The Google Nest Thermostat is a step up from outdated programmable thermostats that have a combination of wiring and AA batteries for power.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 Issues

If it can’t get ample electricity, Nest says you may encounter some of these problems:

  1. Bad battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t stop running.
  5. Your system is making odd 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 message on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is always running, won’t run or turns off and on repeatedly in a short period of time.

You may worry something is wrong with your heating and cooling system, but if you just got the Nest, we advise you check your thermostat initially. This is especially pertinent if the weather is temperate, and you haven’t been using your heat or air conditioning consistently.
