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 on the market today. And for good reason. It figures out your temperature preferences and creates an energy-efficient schedule to match. And using geofencing with your phone, the Nest Learning Thermostat and Nest E realize when you’re at your house or away and can raise and lower settings to help you save even more.

The Nest works with a vast range of 24-volt heating and cooling systems, but it’s always a smart idea to use the Nest thermostat compatibility checker before getting one. Don’t forget to check with your energy supplier 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 on your own or call a HVAC pro like Kapaun & Brown Inc.. If you’re wiring it yourself, you’ll notice 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 the majority of cases, Nest says this isn’t a problem since the thermostat can draw ample power from other heating and cooling wires.

Sometimes, your heating and cooling system could have to have 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 use a combination of wiring and AA batteries for power. It has a rechargeable lithium-ion battery and wiring to connect to Wi-Fi, power its digital display and turn on your heating and cooling system.

8 Common Nest Thermostat Problems

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

  1. Bad battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t turn off.
  5. Your system is making 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, along the lines of “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 could think something is up with your heating and cooling system, but if you just installed the Nest, we advise you start with your thermostat initially. This is especially pertinent if the weather is moderate, and you haven’t been running your heat or air conditioning frequently.
