Why Your Nest Thermostat Isn't Running Right and How to Solve the Problem

April 13, 2021

The Nest thermostat is one of the best-selling smart thermostats you can get. And for good reason. It figures out 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 residence or away and can change settings to help you save even more.

The Nest is compatible with a full range of 24-volt heating and cooling systems, but it’s always a smart idea to use the Nest thermostat compatibility checker before getting one. Don’t forget to contact your energy provider for valuable rebates, as you might be able to get a Nest for free or close to it.

Once you’ve made sure it’s compatible, you can either wire it without help or hire a HVAC pro like All Weather Heating & Air Conditioning Inc. If you’re putting it in 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 house or HVAC system is older, you might not have one of these wires. In most cases, Nest says this isn’t a problem since the thermostat can get adequate power from other heating and cooling wires.

In some instances, your heating and cooling system might 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The Google Nest Thermostat is better than outdated programmable thermostats that have a combination of wiring and AA batteries for power. It uses a rechargeable lithium-ion battery and wiring to connect to Wi-Fi, power its digital display and operate your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t draw adequate power, Nest says you could have some of these issues:

  1. Short battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t turn off.
  5. Your system is producing odd 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, along the lines of “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 worry something is up with your heating and cooling system, but if you just got the Nest, it’s best to check your thermostat right away. This is especially timely if the weather is mild, and you haven’t been running your heat or air conditioning frequently.
