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

April 13, 2021

The Nest thermostat is one of the most popular smart thermostats on the market today. And for good reason. It picks up on your temperature preferences and develops an energy-efficient schedule to match. And by geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your house or out and about and can change temperatures to help you save even more.

The Nest works with a wide range of 24-volt heating and cooling systems, but it’s always a good idea to check the Nest thermostat compatibility checker before purchasing one. Don’t forget to check with your energy company for valuable rebates, because you may be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either hook it up without help or hire a HVAC professional like Morgner Inc. Air Conditioning & Heating. If you’re wiring it on your own, you’ll see 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. In the majority of cases, Nest says this isn’t a setback because the thermostat can get ample power from other heating and cooling wires.

In some instances, 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The Google Nest Thermostat is an improvement from outdated programmable thermostats that have a combination of wiring and AA batteries for power.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 run your heating and cooling system.

8 Common Nest Thermostat Problems

If it can’t get enough juice, Nest says you might encounter some of these troubles:

  1. Short battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t turn off.
  5. Your system is making odd noises, including chattering, stuttering, clicking or thumping.
  6. Heating or cooling is short cycling, or repeatedly 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 always running, won’t switch on or turns off and on frequently in a short period of time.

You could believe something is wrong with your heating and cooling system, but if you just started using the Nest, we recommend you begin with your thermostat first. This is especially timely if the weather is mild, and you haven’t been using your heat or air conditioning frequently.
