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

April 13, 2021

The Nest thermostat is one of the most popular smart thermostats on the market today. And for good reason. It picks up on your temperature preferences and creates an energy-efficient schedule to match. And using 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 temps 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 talk 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 made sure it’s compatible, you can either hook it up without help or hire a HVAC professional like Ilten's Incorporated. If you’re wiring it without help, you’ll see 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. Most of the time, Nest says this isn’t an issue because the thermostat can pull ample power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is better than outdated programmable thermostats that rely on a combination of wiring and AA batteries for power. It relies on 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 could have some of these problems:

  1. Short battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t stop running.
  5. Your system is making 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 notification on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously working, won’t turn on or turns off and on rapidly in a short period of time.

You may believe something is suspect with your heating and cooling system, but if you just started using the Nest, we recommend you check your thermostat initially. This is especially true if the weather is temperate, and you haven’t been relying on your heat or air conditioning consistently.
