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 on the market today. And for good reason. It picks up on your temperature preferences and develops an energy-efficient schedule to match. And by geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your house or away and can change temperatures to help you save even more.

The Nest is compatible with a vast range of 24-volt heating and cooling systems, but it’s always a smart idea to visit the Nest thermostat compatibility checker before purchasing one. Don’t forget to talk with your energy supplier for valuable rebates, as you could be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either hook it up without help or contact a HVAC pro like Airmax Long Island 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. Most of the time, Nest says this isn’t a setback because the thermostat can get ample power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Issues

The Google Nest Thermostat is better than older programmable thermostats that rely on 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 run your heating and cooling system.

8 Common Nest Thermostat Issues

If it can’t receive enough electricity, Nest says you may have some of these issues:

  1. Poor battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t stop running.
  5. Your system is creating weird noises, like 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, like “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 suspect with your heating and cooling system, but if you just started using the Nest, it’s best to start with your thermostat right away. This is especially timely if the weather is moderate, and you haven’t been relying on your heat or air conditioning consistently.
