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 makes an energy-efficient schedule to match. And using geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your house or out and about and can raise and lower temperatures 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 wise idea to check the Nest thermostat compatibility checker before purchasing one. Don’t forget to contact your energy supplier for valuable rebates, since you could 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 on your own or contact a HVAC professional like Northglenn Heating & Air Conditioning. If you’re wiring it on your own, you’ll notice 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 most cases, Nest says this isn’t a problem because the thermostat can draw enough power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is better than older programmable thermostats that rely on a combination of wiring and AA batteries for power. It has 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 Malfunctions

If it can’t draw adequate juice, Nest says you could run into 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 abruptly turns on or off, or won’t shut off.
  5. Your system is creating strange noises, including 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, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly working, won’t turn on or turns off and on repeatedly in a short period of time.

You could believe something is wrong with your heating and cooling system, but if you just got the Nest, we recommend you check your thermostat right away. This is especially true if the weather is temperate, and you haven’t been using your heat or air conditioning much.
