The Nest thermostat is one of the most popular smart thermostats on the market today. And for good reason. It learns your temperature preferences and develops 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 house or gone and can change 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 visit the Nest thermostat compatibility checker before purchasing one. Don’t forget to contact your energy supplier for valuable rebates, because you could 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 call a HVAC specialist like Interstate Heating & Air Conditioning. If you’re putting it in yourself, 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 the majority of cases, Nest says this isn’t a setback since the thermostat can pull ample power from other heating and cooling wires.

In some cases, your heating and cooling system could need 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 have 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 run your heating and cooling system.

8 Common Nest Thermostat Malfunctions

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

  1. Poor battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t turn off.
  5. Your system is making strange noises, including chattering, stuttering, clicking or thumping.
  6. Heating or cooling is short cycling, or repeatedly 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 always running, won’t switch on or turns off and on rapidly in a short period of time.

You could believe something is suspect 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 true if the weather is temperate, and you haven’t been using your heat or air conditioning much.
