The Nest thermostat is one of the most popular smart thermostats on the market today. And for good reason. It figures out your temperature preferences and develops 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 home or gone and can raise and lower temps to help you save even more.

The Nest is compatible with a full range of 24-volt heating and cooling systems, but it’s always a smart idea to check the Nest thermostat compatibility checker before purchasing one. Don’t forget to check with your energy supplier for valuable rebates, as 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 on your own or hire a HVAC specialist like Vogts Heating & Air. If you’re installing it yourself, you’ll spot a terminal for the C-wire, or common wire. This wire is only used for powering your thermostat. If your home or HVAC system is older, you might not have one of these wires. In the majority of cases, Nest says this isn’t a problem as the thermostat can pull 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 an improvement from older programmable thermostats that have a combination of wiring and AA batteries for power. It uses 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 ample juice, Nest says you could have some of these issues:

  1. Short battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t stop running.
  5. Your system is making weird 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 notification on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously running, won’t switch on or turns off and on frequently in a short period of time.

You may worry something is up with your heating and cooling system, but if you just installed the Nest, it’s best to begin with your thermostat initially. This is especially true if the weather is temperate, and you haven’t been using your heat or air conditioning frequently.
