The Nest thermostat is one of the best-selling smart thermostats you can buy. And for good reason. It picks up on your temperature preferences and creates 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 house or gone and can change temperatures to help you save even more.

The Nest works with a full range of 24-volt heating and cooling systems, but it’s always a good idea to visit the Nest thermostat compatibility checker before getting one. Don’t forget to contact your energy supplier for valuable rebates, as you might 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 yourself or contact a HVAC pro like AC Sales. If you’re wiring it yourself, you’ll notice a terminal for the C-wire, or common wire. This wire is only used for powering your thermostat. If your residence or HVAC system is older, you might not have one of these wires. Most of the time, Nest says this isn’t a setback as the thermostat can get adequate power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Issues

The Google Nest Thermostat is a step up from older programmable thermostats that have 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 Problems

If it can’t receive ample juice, Nest says you might have some of these problems:

  1. Poor battery life.
  2. Thermostat motion sensing won’t work.
  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 producing strange 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, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is always working, won’t turn on or turns off and on repeatedly in a short period of time.

You may think something is wrong with your heating and cooling system, but if you just installed the Nest, we recommend you begin with your thermostat first. This is especially pertinent if the weather is temperate, and you haven’t been running your heat or air conditioning consistently.
