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 develops an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your residence or out and about and can change temperatures to help you save even more.

The Nest is compatible with a full range of 24-volt heating and cooling systems, but it’s always a good idea to use the Nest thermostat compatibility checker before installing one. Don’t forget to check with your energy provider for valuable rebates, since you may be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either install it without help or hire a HVAC specialist like Indoor Comfort Systems HVAC. If you’re putting it in without help, you’ll notice a terminal for the C-wire, or common wire. This wire is only used for powering your thermostat. If your home or HVAC system is older, you might not have one of these wires. In most cases, Nest says this isn’t an issue since the thermostat can draw ample power from other heating and cooling wires.

Sometimes, your heating and cooling system may 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 use 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 run your heating and cooling system.

8 Common Nest Thermostat Problems

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

  1. Poor battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t stop running.
  5. Your system is creating strange 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 message on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously on, won’t turn on or turns off and on frequently in a short period of time.

You may think something is suspect with your heating and cooling system, but if you just got the Nest, we suggest you begin with your thermostat first. This is especially pertinent if the weather is temperate, and you haven’t been running your heat or air conditioning much.
