Why Your Nest Thermostat Isn't Operating Right and How to Solve the Problem

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 develops 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 home or away and can change temps to help you save even more.

The Nest can be used with a vast range of 24-volt heating and cooling systems, but it’s always a smart idea to check the Nest thermostat compatibility checker before purchasing one. Don’t forget to talk with your energy supplier 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 hire a HVAC professional like A2Z Air Inc. If you’re putting it in yourself, 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. Most of the time, Nest says this isn’t a setback because the thermostat can draw ample power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is an improvement from aging programmable thermostats that rely on a combination of wiring and AA batteries for power. It has 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 Malfunctions

If it can’t receive adequate power, Nest says you might experience some of these issues:

  1. Short battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t shut off.
  5. Your system is making 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 notification 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 may worry something is suspect with your heating and cooling system, but if you just got the Nest, it’s best to begin with your thermostat right away. This is especially true if the weather is temperate, and you haven’t been relying on your heat or air conditioning consistently.
