The Nest thermostat is one of the most popular smart thermostats on the market today. And for good reason. It learns your temperature preferences and creates an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your residence or gone and can raise and lower temps to help you save even more.

The Nest can be used with a full range of 24-volt heating and cooling systems, but it’s always a wise idea to use the Nest thermostat compatibility checker before purchasing one. Don’t forget to contact 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 wire it without help or contact a HVAC specialist like Vogts Heating & Air. If you’re wiring it yourself, you’ll spot a terminal for the C-wire, or common wire. This wire is just 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 since the thermostat can draw ample power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Malfunctions

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

8 Common Nest Thermostat Issues

If it can’t receive ample power, Nest says you may encounter 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 suddenly turns on or off, or won’t stop running.
  5. Your system is creating odd noises, including 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 notification on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly running, won’t run or turns off and on rapidly in a short period of time.

You might worry something is wrong with your heating and cooling system, but if you just installed the Nest, we suggest you begin with your thermostat first. This is especially timely if the weather is moderate, and you haven’t been running your heat or air conditioning consistently.
