The Nest thermostat is one of the top-selling smart thermostats you can get. And for good reason. It figures out your temperature preferences and makes 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 home or away and can change temperatures to help you save even more.

The Nest works with a vast range of 24-volt heating and cooling systems, but it’s always a wise idea to use the Nest thermostat compatibility checker before installing one. Don’t forget to talk with your energy supplier for valuable rebates, since 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 hook it up on your own or call a HVAC specialist like Lanz Furnace and Fireplace. 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 house or HVAC system is older, you might not have one of these wires. In the majority of cases, Nest says this isn’t an issue as the thermostat can draw ample power from other heating and cooling wires.

In some cases, 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The Google Nest Thermostat is an improvement from outdated programmable thermostats that rely on a combination of wiring and AA batteries for power.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 Malfunctions

If it can’t get ample power, Nest says you might have some of these issues:

  1. Bad battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t turn off.
  5. Your system is producing strange 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 notification on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously working, won’t switch on or turns off and on frequently in a short period of time.

You could worry something is suspect with your heating and cooling system, but if you just got the Nest, we advise you 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.
