The Nest thermostat is one of the most popular smart thermostats you can buy. And for good reason. It figures out your temperature preferences and makes an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your house or gone and can raise and lower settings 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 check the Nest thermostat compatibility checker before installing one. Don’t forget to contact your energy provider for valuable rebates, as you may be able to get a Nest for free or close to it.

Once you’ve confirmed it’s compatible, you can either wire it yourself or contact a HVAC pro like Everest Heating & Cooling. If you’re wiring it on your own, you’ll spot a terminal for the C-wire, or common wire. This wire is solely used for powering your thermostat. If your residence or HVAC system is older, you might not have one of these wires. In most cases, Nest says this isn’t a problem as the thermostat can get ample power from other heating and cooling wires.

Sometimes, your heating and cooling system might have to have that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is a step up from older programmable thermostats that rely on 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 Malfunctions

If it can’t draw adequate juice, Nest says you may run into some of these issues:

  1. Poor battery life.
  2. Thermostat motion sensing is disabled.
  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 notification on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
  8. The system fan is always working, won’t turn on or turns off and on repeatedly in a short period of time.

You may think something is wrong with your heating and cooling system, but if you just installed the Nest, we advise you begin with your thermostat first. This is especially true if the weather is temperate, and you haven’t been using your heat or air conditioning much.
