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

April 13, 2021

The Nest thermostat is one of the best-selling smart thermostats on the market today. And for good reason. It figures out 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 residence or out and about and can adjust temps to help you save even more.

The Nest works with a full range of 24-volt heating and cooling systems, but it’s always a wise idea to visit the Nest thermostat compatibility checker before purchasing one. Don’t forget to contact your energy provider for valuable rebates, because you could be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either install it yourself or contact a HVAC professional like Vogts Heating & Air. If you’re putting it in yourself, you’ll spot 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 setback since the thermostat can pull enough power from other heating and cooling wires.

In some instances, your heating and cooling system might 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The Google Nest Thermostat is a step up from outdated programmable thermostats that have a combination of wiring and AA batteries for power.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 uses 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 Issues

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

  1. Bad battery life.
  2. Thermostat motion sensing is disabled.
  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 creating weird 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 message on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly running, won’t turn on or turns off and on rapidly in a short period of time.

You could think something is suspect with your heating and cooling system, but if you just got the Nest, we recommend you begin with your thermostat first. This is especially pertinent if the weather is mild, and you haven’t been running your heat or air conditioning frequently.
