The Nest thermostat is one of the most popular smart thermostats you can get. And for good reason. It learns your temperature preferences and makes 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 home or out and about and can change settings to help you save even more.
The Nest can be used with a wide 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 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 checked it’s compatible, you can either install it yourself or contact a HVAC specialist like Walter's-Eaton's Electric, Plumbing, Heating & AC. If you’re putting it in on your own, you’ll spot a terminal for the C-wire, or common wire. This wire is just 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 setback as the thermostat can pull ample power from other heating and cooling wires.
In some cases, your heating and cooling system might need that C-wire. And here’s why.
Why Your Nest Keeps Losing Power and Other Issues
The Google Nest Thermostat is better than outdated programmable thermostats that rely on a combination of wiring and AA batteries for power.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 sync with Wi-Fi, power its digital display and operate your heating and cooling system.
8 Common Nest Thermostat Issues
If it can’t draw adequate juice, Nest says you might have some of these issues:
- Poor 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 making strange 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 constantly working, won’t turn on or turns off and on frequently in a short period of time.
You might worry something is wrong with your heating and cooling system, but if you just got the Nest, we advise you begin with your thermostat first. This is especially timely if the weather is moderate, and you haven’t been running your heat or air conditioning frequently.
