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

April 13, 2021

The Nest thermostat is one of the most popular smart thermostats you can buy. And for good reason. It learns your temperature preferences and makes an energy-efficient schedule to match. And using geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your home or gone and can raise and lower temperatures 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 visit the Nest thermostat compatibility checker before purchasing 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 made sure it’s compatible, you can either install it yourself or contact a HVAC pro like I-Deal HVAC. If you’re wiring it yourself, you’ll notice 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 the majority of cases, Nest says this isn’t a setback as the thermostat can pull adequate power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is a step up from outdated programmable thermostats that rely on a combination of wiring and AA batteries for power.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 run your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t receive adequate electricity, Nest says you might experience 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 shut off.
  5. Your system is creating strange noises, like 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, like “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly running, won’t turn on or turns off and on frequently in a short period of time.

You might worry something is up with your heating and cooling system, but if you just got the Nest, we recommend you start with your thermostat right away. This is especially true if the weather is moderate, and you haven’t been using your heat or air conditioning much.
