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

April 13, 2021

The Nest thermostat is one of the best-selling smart thermostats you can buy. And for good reason. It picks up on your temperature preferences and develops 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 house or gone and can raise and lower temperatures to help you save even more.

The Nest can be used with a wide range of 24-volt heating and cooling systems, but it’s always a wise idea to visit the Nest thermostat compatibility checker before installing one. Don’t forget to check 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 hook it up on your own or call a HVAC specialist like Integrity AC & Heating LLC. If you’re putting it in without help, you’ll notice a terminal for the C-wire, or common wire. This wire is solely used for powering your thermostat. If your house 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 pull adequate power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Problems

The Google Nest Thermostat is a step up from outdated programmable thermostats that have a combination of wiring and AA batteries for power. It has a rechargeable lithium-ion battery and wiring to sync with Wi-Fi, power its digital display and turn on your heating and cooling system.

8 Common Nest Thermostat Problems

If it can’t get enough juice, Nest says you could run into some of these troubles:

  1. Bad battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t stop running.
  5. Your system is producing weird 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 notification on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously working, won’t run or turns off and on rapidly in a short period of time.

You could believe something is wrong with your heating and cooling system, but if you just installed the Nest, we advise you start with your thermostat right away. This is especially timely if the weather is temperate, and you haven’t been relying on your heat or air conditioning consistently.
