The Nest thermostat is one of the best-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 using geofencing with your phone, the Nest Learning Thermostat and Nest E realize when you’re at your residence or out and about and can raise and lower temps to help you save even more.

The Nest works with a wide range of 24-volt heating and cooling systems, but it’s always a smart idea to visit the Nest thermostat compatibility checker before installing one. Don’t forget to contact your energy supplier for valuable rebates, because 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 yourself or hire a HVAC professional like Olde Towne Heating & Air. If you’re installing it yourself, you’ll see 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. Most of the time, Nest says this isn’t a problem because the thermostat can get enough power from other heating and cooling wires.

In some cases, your heating and cooling system could 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 aging programmable thermostats that use 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 operate your heating and cooling system.

8 Common Nest Thermostat Issues

If it can’t get enough power, Nest says you might run into some of these troubles:

  1. Short battery life.
  2. Thermostat motion sensing won’t work.
  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 making odd 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 notice on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
  8. The system fan is always on, won’t run or turns off and on rapidly in a short period of time.

You may worry something is wrong with your heating and cooling system, but if you just started using the Nest, we advise you start with your thermostat right away. This is especially pertinent if the weather is temperate, and you haven’t been using your heat or air conditioning frequently.
