The Nest thermostat is one of the most popular smart thermostats you can buy. And for good reason. It learns your temperature preferences and makes 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 house or away and can adjust temps to help you save even more.

The Nest can be used with a wide 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, because you might 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 Custom Air Systems Inc. If you’re putting it in without help, 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 most cases, Nest says this isn’t a problem because the thermostat can get ample power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is better than aging programmable thermostats that use a combination of wiring and AA batteries for power. It relies on 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 ample power, Nest says you might run into some of these problems:

  1. Poor 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 producing 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 message on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously running, won’t run or turns off and on repeatedly in a short period of time.

You could worry something is suspect with your heating and cooling system, but if you just installed the Nest, it’s best to begin with your thermostat right away. This is especially timely if the weather is temperate, and you haven’t been relying on your heat or air conditioning much.
