The Nest thermostat is one of the top-selling 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 realize when you’re at your house or away and can change settings to help you save even more.

The Nest is compatible with a vast 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 might be able to get a Nest for free or close to it.

Once you’ve confirmed it’s compatible, you can either wire it without help or call a HVAC specialist like Connolly Electric & Mechanical. 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 house 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 because the thermostat can pull 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 better than older programmable thermostats that use a combination of wiring and AA batteries for power. It uses 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 get adequate electricity, Nest says you could encounter some of these problems:

  1. Bad battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t shut off.
  5. Your system is making odd noises, like 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 continuously working, won’t switch on or turns off and on repeatedly in a short period of time.

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