The Nest thermostat is one of the top-selling smart thermostats you can get. And for good reason. It figures out your temperature preferences and makes 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 home or away 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 smart idea to use the Nest thermostat compatibility checker before installing one. Don’t forget to talk with your energy provider for valuable rebates, because you might be able to get a Nest for free or close to it.
Once you’ve confirmed it’s compatible, you can either hook it up yourself or contact a HVAC pro like Fleming Heating & Air Conditioning Inc. If you’re putting it in 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 house or HVAC system is older, you might not have one of these wires. Most of the time, Nest says this isn’t a problem since the thermostat can draw ample power from other heating and cooling wires.
In some instances, your heating and cooling system may require that C-wire. And here’s why.
Why Your Nest Keeps Losing Power and Other Malfunctions
The Google Nest Thermostat is an improvement from outdated programmable thermostats that rely on a combination of wiring and AA batteries for power.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 turn on your heating and cooling system.
8 Common Nest Thermostat Issues
If it can’t get ample electricity, Nest says you could encounter some of these problems:
- Bad battery life.
- Thermostat motion sensing is disabled.
- Your thermostat sometimes disconnects from Wi-Fi.
- Your system abruptly turns on or off, or won’t turn off.
- Your system is producing odd noises, including chattering, stuttering, clicking or thumping.
- Heating or cooling is short cycling, or repeatedly turning on and off in a short period of time.
- There is a delay notice on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
- The system fan is always running, won’t turn on or turns off and on rapidly in a short period of time.
You may think something is suspect with your heating and cooling system, but if you just started using the Nest, we suggest you begin with your thermostat first. This is especially pertinent if the weather is moderate, and you haven’t been using your heat or air conditioning much.
