The Nest thermostat is one of the top-selling smart thermostats on the market today. And for good reason. It figures out your temperature preferences and creates an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E realize when you’re at your home or gone and can adjust settings 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 good idea to use the Nest thermostat compatibility checker before getting one. Don’t forget to contact your energy supplier for valuable rebates, because you could be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either install it without help or call a HVAC professional like Point Heating & Cooling. If you’re installing it without help, 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 most cases, Nest says this isn’t a setback as the thermostat can pull adequate power from other heating and cooling wires.

In some instances, your heating and cooling system could require 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 aging 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 Problems

If it can’t get enough power, Nest says you may encounter some of these troubles:

  1. Poor battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t shut off.
  5. Your system is creating odd noises, such as chattering, stuttering, clicking or thumping.
  6. Heating or cooling is short cycling, or frequently 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 continuously running, won’t run or turns off and on repeatedly in a short period of time.

You could believe something is suspect with your heating and cooling system, but if you just installed the Nest, it’s best to start with your thermostat right away. This is especially true if the weather is temperate, and you haven’t been relying on your heat or air conditioning frequently.
