The Nest thermostat is one of the top-selling smart thermostats on the market today. And for good reason. It figures out your temperature preferences and develops 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 residence or out and about and can change settings to help you save even more.
The Nest works with a vast 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 company for valuable rebates, as you might be able to get a Nest for free or close to it.
Once you’ve confirmed it’s compatible, you can either wire it without help or hire a HVAC pro like ACS Heating and Air Conditioning. If you’re putting it in yourself, you’ll notice a terminal for the C-wire, or common wire. This wire is solely used for powering your thermostat. If your house or HVAC system is older, you might not have one of these wires. In most cases, Nest says this isn’t an issue as the thermostat can pull adequate power from other heating and cooling wires.
In some instances, your heating and cooling system might need 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 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 adequate power, Nest says you could have some of these issues:
- Poor battery life.
- Thermostat motion sensing won’t operate.
- Your thermostat occasionally disconnects from Wi-Fi.
- Your system abruptly turns on or off, or won’t shut off.
- Your system is producing strange noises, such as 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 notification on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
- The system fan is constantly working, won’t run or turns off and on repeatedly in a short period of time.
You might believe something is up with your heating and cooling system, but if you just got the Nest, it’s best to start with your thermostat first. This is especially timely if the weather is mild, and you haven’t been running your heat or air conditioning frequently.
