Why Your Nest Thermostat Isn't Operating 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 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 residence or out and about and can adjust temperatures to help you save even more.

The Nest works 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 talk with your energy company 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 hook it up without help or hire a HVAC pro like Gee & Missler Heating & Air Conditioning. If you’re installing it without help, 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 the majority of cases, Nest says this isn’t an issue as the thermostat can draw 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The Google Nest Thermostat is a step up from outdated programmable thermostats that rely on a combination of wiring and AA batteries for power.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 run your heating and cooling system.

8 Common Nest Thermostat Problems

If it can’t draw ample electricity, Nest says you may experience some of these troubles:

  1. Bad battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t shut off.
  5. Your system is creating strange 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 notice on your Nest thermostat’s screen, like “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 might think something is up with your heating and cooling system, but if you just got the Nest, we advise you begin with your thermostat first. This is especially pertinent if the weather is temperate, and you haven’t been relying on your heat or air conditioning frequently.
