The Nest thermostat is one of the most popular smart thermostats you can get. And for good reason. It figures out your temperature preferences and creates 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 away and can adjust temps to help you save even more.

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

Once you’ve made sure it’s compatible, you can either wire it without help or contact a HVAC professional like B & B Heating & Cooling. If you’re installing it 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 house 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 as the thermostat can get ample power from other heating and cooling wires.

In some cases, your heating and cooling system might require that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Problems

The Google Nest Thermostat is a step up from aging programmable thermostats that use 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 Issues

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

  1. Short battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t stop running.
  5. Your system is producing weird noises, like 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 always running, won’t switch on or turns off and on rapidly in a short period of time.

You could think something is suspect with your heating and cooling system, but if you just started using the Nest, we recommend you check your thermostat right away. This is especially pertinent if the weather is moderate, and you haven’t been relying on your heat or air conditioning frequently.
