The Nest thermostat is one of the most popular 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 are aware of when you’re at your house or out and about and can adjust temperatures to help you save even more.

The Nest works with a full range of 24-volt heating and cooling systems, but it’s always a smart idea to use the Nest thermostat compatibility checker before installing one. Don’t forget to contact your energy company 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 install it yourself or contact a HVAC professional like B&D Air Conditioning. If you’re installing it without help, you’ll spot a terminal for the C-wire, or common wire. This wire is just 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 problem as the thermostat can get adequate power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is better than outdated programmable thermostats that have a combination of wiring and AA batteries for power. It relies on 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 could have some of these troubles:

  1. Bad battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t shut off.
  5. Your system is producing odd noises, such as chattering, stuttering, clicking or thumping.
  6. Heating or cooling is short cycling, or frequently 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 run or turns off and on repeatedly in a short period of time.

You could think something is suspect with your heating and cooling system, but if you just started using the Nest, it’s best to 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 much.
