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 using geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your residence or away and can change settings 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 wise idea to visit the Nest thermostat compatibility checker before getting one. Don’t forget to contact your energy supplier 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 install it yourself or call a HVAC specialist like Rescue Heating & Air. If you’re putting it in on your own, you’ll spot a terminal for the C-wire, or common wire. This wire is only 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 problem as the thermostat can draw ample power from other heating and cooling wires.

In some instances, your heating and cooling system might 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 aging programmable thermostats that have a combination of wiring and AA batteries for power. It has a rechargeable lithium-ion battery and wiring to sync with Wi-Fi, power its digital display and turn on your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t receive enough power, Nest says you could encounter some of these troubles:

  1. Bad battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t shut 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, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously running, won’t turn on or turns off and on repeatedly in a short period of time.

You could worry something is up with your heating and cooling system, but if you just started using the Nest, we advise you start with your thermostat initially. This is especially timely if the weather is temperate, and you haven’t been using your heat or air conditioning frequently.
