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

April 13, 2021

The Nest thermostat is one of the top-selling smart thermostats you can buy. And for good reason. It picks up on your temperature preferences and makes an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your residence or out and about and can change 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 good idea to visit the Nest thermostat compatibility checker before purchasing one. Don’t forget to talk with your energy company for valuable rebates, since you could be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either install it yourself or call a HVAC pro like Watts Electric & A/C Inc. If you’re putting it in on your own, you’ll notice a terminal for the C-wire, or common wire. This wire is just used for powering your thermostat. If your residence 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 because the thermostat can pull ample power from other heating and cooling wires.

In some cases, your heating and cooling system may have to have that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is an improvement from older programmable thermostats that have a combination of wiring and AA batteries for power. It relies on a rechargeable lithium-ion battery and wiring to link to Wi-Fi, power its digital display and operate your heating and cooling system.

8 Common Nest Thermostat Problems

If it can’t get enough power, Nest says you could run into some of these issues:

  1. Short battery life.
  2. Thermostat motion sensing won’t operate.
  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 strange 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 notification on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly working, won’t switch on or turns off and on repeatedly in a short period of time.

You might think something is suspect with your heating and cooling system, but if you just started using the Nest, it’s best to check your thermostat first. This is especially timely if the weather is moderate, and you haven’t been using your heat or air conditioning frequently.
