The Nest thermostat is one of the most popular smart thermostats on the market today. And for good reason. It picks up on 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 out and about and can raise and lower temperatures 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 check the Nest thermostat compatibility checker before getting one. Don’t forget to talk with your energy company for valuable rebates, since you may 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 without help or call a HVAC pro like Kohles & Bach Heating & Cooling. If you’re putting it in 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 most cases, Nest says this isn’t an issue because the thermostat can draw enough power from other heating and cooling wires.

In some instances, your heating and cooling system may have to have 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The Google Nest Thermostat is a step up from outdated programmable thermostats that have a combination of wiring and AA batteries for power. It uses a rechargeable lithium-ion battery and wiring to sync with Wi-Fi, power its digital display and run your heating and cooling system.

8 Common Nest Thermostat Issues

If it can’t get ample juice, Nest says you could run into some of these problems:

  1. Poor battery life.
  2. Thermostat motion sensing won’t work.
  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 creating weird noises, such as 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, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is always working, won’t turn on or turns off and on rapidly in a short period of time.

You may believe something is suspect with your heating and cooling system, but if you just installed the Nest, we recommend you begin with your thermostat first. This is especially true if the weather is mild, and you haven’t been using your heat or air conditioning much.
