The Nest thermostat is one of the most popular smart thermostats you can get. And for good reason. It figures out your temperature preferences and creates an energy-efficient schedule to match. And using 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 temps to help you save even more.
The Nest can be used with a vast range of 24-volt heating and cooling systems, but it’s always a smart idea to check the Nest thermostat compatibility checker before purchasing one. Don’t forget to check with your energy provider 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 install it yourself or hire a HVAC pro like Airmax Long Island. If you’re installing 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 residence or HVAC system is older, you might not have one of these wires. In the majority of cases, Nest says this isn’t a problem as the thermostat can draw adequate 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 Issues
The Google Nest Thermostat is better than older programmable thermostats that rely on a combination of wiring and AA batteries for power. It uses a rechargeable lithium-ion battery and wiring to sync with Wi-Fi, power its digital display and run your heating and cooling system.
8 Common Nest Thermostat Malfunctions
If it can’t receive adequate juice, Nest says you might run into some of these issues:
- Short battery life.
- Thermostat motion sensing is disabled.
- Your thermostat every now and then disconnects from Wi-Fi.
- Your system abruptly turns on or off, or won’t turn off.
- Your system is creating odd noises, including chattering, stuttering, clicking or thumping.
- Heating or cooling is short cycling, or frequently turning on and off in a short period of time.
- There is a delay notification on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
- The system fan is always running, won’t run 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 started using the Nest, we suggest you start with your thermostat first. This is especially timely if the weather is temperate, and you haven’t been running your heat or air conditioning consistently.
