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

April 13, 2021

The Nest thermostat is one of the most popular smart thermostats on the market today. And for good reason. It picks up on 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 home or gone and can change temperatures to help you save even more.

The Nest is compatible with a vast range of 24-volt heating and cooling systems, but it’s always a wise idea to visit the Nest thermostat compatibility checker before purchasing one. Don’t forget to contact your energy company for valuable rebates, because you might be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either wire it without help or contact a HVAC specialist like Freed Heating & Air Conditioning. If you’re putting it in without help, you’ll see a terminal for the C-wire, or common wire. This wire is solely used for powering your thermostat. If your residence or HVAC system is older, you might not have one of these wires. In most cases, Nest says this isn’t a setback because the thermostat can pull ample power from other heating and cooling wires.

In some cases, your heating and cooling system may 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The Google Nest Thermostat is a step up from outdated programmable thermostats that rely on a combination of wiring and AA batteries for power.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 has 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 get adequate power, Nest says you might encounter some of these issues:

  1. Bad battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t stop running.
  5. Your system is creating odd noises, including 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 always working, won’t turn on or turns off and on rapidly in a short period of time.

You might think something is suspect with your heating and cooling system, but if you just installed the Nest, we suggest you start 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 consistently.
