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 you can get. And for good reason. It learns your temperature preferences and creates an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your house or away and can adjust temperatures 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 purchasing one. Don’t forget to contact your energy company for valuable rebates, as you could be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either wire it yourself or hire a HVAC specialist like Stephen Hurst Pack Heating and Cooling, Inc. If you’re installing 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 house or HVAC system is older, you might not have one of these wires. Most of the time, Nest says this isn’t an issue because the thermostat can pull enough power from other heating and cooling wires.

In some instances, 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 an improvement from aging programmable thermostats that have 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 turn on your heating and cooling system.

8 Common Nest Thermostat Issues

If it can’t draw ample juice, Nest says you could have some of these troubles:

  1. Bad battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t turn off.
  5. Your system is creating odd noises, such as chattering, stuttering, clicking or thumping.
  6. Heating or cooling is short cycling, or frequently 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 continuously running, won’t switch on or turns off and on repeatedly in a short period of time.

You may worry something is suspect with your heating and cooling system, but if you just started using the Nest, we recommend you check your thermostat initially. This is especially pertinent if the weather is mild, and you haven’t been running your heat or air conditioning much.
