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

April 13, 2021

The Nest thermostat is one of the most popular smart thermostats you can buy. And for good reason. It picks up on your temperature preferences and develops an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E realize when you’re at your house or out and about and can raise and lower temps 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 visit the Nest thermostat compatibility checker before purchasing one. Don’t forget to check with your energy company for valuable rebates, since 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 wire it on your own or contact a HVAC pro like Point Heating & Cooling. If you’re wiring it yourself, you’ll see 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 most cases, Nest says this isn’t an issue as the thermostat can pull enough power from other heating and cooling wires.

Sometimes, your heating and cooling system could require that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Problems

The Google Nest Thermostat is a step up from older programmable thermostats that rely on a combination of wiring and AA batteries for power. It uses a rechargeable lithium-ion battery and wiring to link to Wi-Fi, power its digital display and run your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t draw ample electricity, Nest says you might encounter some of these problems:

  1. Short battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t turn off.
  5. Your system is producing 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 notice on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously working, won’t run or turns off and on frequently in a short period of time.

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