The Nest thermostat is one of the top-selling smart thermostats on the market today. And for good reason. It learns your temperature preferences and makes 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 residence or gone and can change temps 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 wise idea to visit the Nest thermostat compatibility checker before installing one. Don’t forget to contact your energy provider 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 hook it up yourself or call a HVAC professional like Air Commander's Heating & Air Conditioning Co.. If you’re putting it in on your own, you’ll spot 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 an issue since the thermostat can pull enough power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is a step up from outdated programmable thermostats that have a combination of wiring and AA batteries for power.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

8 Common Nest Thermostat Malfunctions

If it can’t draw enough electricity, Nest says you might run into some of these issues:

  1. Bad battery life.
  2. Thermostat motion sensing won’t work.
  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 creating weird noises, including chattering, stuttering, clicking or thumping.
  6. Heating or cooling is short cycling, or frequently turning on and off in a short period of time.
  7. There is a delay message on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously working, won’t turn on or turns off and on rapidly in a short period of time.

You may think something is wrong with your heating and cooling system, but if you just started using the Nest, we suggest you begin with your thermostat first. This is especially pertinent if the weather is mild, and you haven’t been relying on your heat or air conditioning much.
