The Nest thermostat is one of the best-selling smart thermostats you can buy. And for good reason. It learns your temperature preferences and develops an energy-efficient schedule to match. And by geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your home or out and about and can raise and lower temps to help you save even more.

The Nest can be used with a full range of 24-volt heating and cooling systems, but it’s always a wise idea to check the Nest thermostat compatibility checker before installing one. Don’t forget to contact your energy supplier for valuable rebates, as 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 hook it up yourself or contact a HVAC pro like Total Assurance AC & Heating. If you’re putting it in yourself, you’ll spot a terminal for the C-wire, or common wire. This wire is just used for powering your thermostat. If your home or HVAC system is older, you might not have one of these wires. Most of the time, Nest says this isn’t an issue because the thermostat can get adequate power from other heating and cooling wires.

In some cases, 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 a step up from older programmable thermostats that have a combination of wiring and AA batteries for power. It has 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 receive adequate juice, Nest says you may run into some of these troubles:

  1. Bad battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t stop running.
  5. Your system is producing 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 notice on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is always working, won’t switch on or turns off and on rapidly in a short period of time.

You might believe something is suspect with your heating and cooling system, but if you just installed the Nest, we suggest you begin with your thermostat first. This is especially pertinent if the weather is mild, and you haven’t been relying on your heat or air conditioning consistently.
