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

April 13, 2021

The Nest thermostat is one of the top-selling smart thermostats you can get. And for good reason. It figures out your temperature preferences and makes an energy-efficient schedule to match. And by geofencing with your phone, the Nest Learning Thermostat and Nest E realize when you’re at your house or out and about and can change 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 check the Nest thermostat compatibility checker before installing one. Don’t forget to contact your energy company for valuable rebates, as you might 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 hire a HVAC professional like Comfort Zone Inc. If you’re wiring it on your own, you’ll spot a terminal for the C-wire, or common wire. This wire is just 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 since the thermostat can get ample power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Issues

The Google Nest Thermostat is an improvement from aging programmable thermostats that have a combination of wiring and AA batteries for power. It relies on a rechargeable lithium-ion battery and wiring to link to Wi-Fi, power its digital display and turn on your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t get adequate electricity, Nest says you might have some of these troubles:

  1. Short battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t turn off.
  5. Your system is creating strange 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 notice on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly on, won’t run or turns off and on frequently in a short period of time.

You may worry something is suspect with your heating and cooling system, but if you just installed the Nest, we suggest you check your thermostat initially. This is especially timely if the weather is mild, and you haven’t been using your heat or air conditioning consistently.
