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

April 13, 2021

The Nest thermostat is one of the most popular smart thermostats you can get. And for good reason. It picks up on your temperature preferences and develops an energy-efficient schedule to match. And using geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your residence or away and can adjust settings 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 good idea to use the Nest thermostat compatibility checker before purchasing one. Don’t forget to talk with your energy provider for valuable rebates, since 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 wire it on your own or hire a HVAC pro like Allstar Heating & Air Conditioning. If you’re wiring it on your own, you’ll spot a terminal for the C-wire, or common wire. This wire is only 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 problem as the thermostat can get ample power from other heating and cooling wires.

Sometimes, your heating and cooling system could need 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 older programmable thermostats that have 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 operate your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t draw enough electricity, Nest says you may run into some of these problems:

  1. Poor battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t shut off.
  5. Your system is making odd noises, like chattering, stuttering, clicking or thumping.
  6. Heating or cooling is short cycling, or constantly turning on and off in a short period of time.
  7. There is a delay message on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly on, won’t turn on or turns off and on rapidly in a short period of time.

You may worry something is suspect with your heating and cooling system, but if you just got the Nest, it’s best to start with your thermostat first. This is especially pertinent if the weather is moderate, and you haven’t been using your heat or air conditioning consistently.
