The Nest thermostat is one of the best-selling smart thermostats you can buy. And for good reason. It figures out your temperature preferences and makes an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your residence or out and about and can adjust settings 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 use the Nest thermostat compatibility checker before installing 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 Assured Appliance & Heating & Air. If you’re installing it on your own, you’ll see a terminal for the C-wire, or common wire. This wire is solely used for powering your thermostat. If your residence or HVAC system is older, you might not have one of these wires. In most cases, Nest says this isn’t a setback because the thermostat can draw ample 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 Problems

The Google Nest Thermostat is an improvement from older programmable thermostats that use a combination of wiring and AA batteries for power. It has a rechargeable lithium-ion battery and wiring to connect to Wi-Fi, power its digital display and turn on your heating and cooling system.

8 Common Nest Thermostat Problems

If it can’t draw ample electricity, Nest says you might encounter some of these troubles:

  1. Bad battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t stop running.
  5. Your system is making weird noises, such as chattering, stuttering, clicking or thumping.
  6. Heating or cooling is short cycling, or repeatedly turning on and off in a short period of time.
  7. There is a delay message on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly running, won’t turn on or turns off and on repeatedly in a short period of time.

You might worry 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 true if the weather is moderate, and you haven’t been relying on your heat or air conditioning frequently.
