The Nest thermostat is one of the most popular smart thermostats you can buy. And for good reason. It picks up on 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 residence or gone and can adjust temperatures to help you save even more.

The Nest is compatible with a wide range of 24-volt heating and cooling systems, but it’s always a wise idea to check the Nest thermostat compatibility checker before getting one. Don’t forget to check 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 checked it’s compatible, you can either wire it yourself or call a HVAC professional like MPC 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 home 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 instances, your heating and cooling system might require that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Problems

The Google Nest Thermostat is better than aging programmable thermostats that rely on a combination of wiring and AA batteries for power. It relies on 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 enough power, Nest says you could encounter some of these issues:

  1. Bad battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t shut off.
  5. Your system is making odd noises, such as 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, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously on, won’t run or turns off and on rapidly in a short period of time.

You might 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 timely if the weather is mild, and you haven’t been relying on your heat or air conditioning consistently.
