The Nest thermostat is one of the best-selling smart thermostats on the market today. And for good reason. It picks up on 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 house or gone and can change settings to help you save even more.
The Nest works with a wide range of 24-volt heating and cooling systems, but it’s always a wise idea to check the Nest thermostat compatibility checker before purchasing one. Don’t forget to talk 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 made sure it’s compatible, you can either install it without help or hire a HVAC specialist like Siloam Springs Heating & AC. If you’re wiring it yourself, you’ll spot a terminal for the C-wire, or common wire. This wire is only used for powering your thermostat. If your residence or HVAC system is older, you might not have one of these wires. Most of the time, Nest says this isn’t a problem as the thermostat can draw enough power from other heating and cooling wires.
In some instances, your heating and cooling system could require that C-wire. And here’s why.
Why Your Nest Keeps Losing Power and Other Issues
The Google Nest Thermostat is an improvement from older programmable thermostats that have a combination of wiring and AA batteries for power. It relies on a rechargeable lithium-ion battery and wiring to sync with Wi-Fi, power its digital display and turn on your heating and cooling system.
8 Common Nest Thermostat Problems
If it can’t draw enough power, Nest says you might run into some of these issues:
- Short battery life.
- Thermostat motion sensing won’t operate.
- Your thermostat occasionally disconnects from Wi-Fi.
- Your system unexpectedly turns on or off, or won’t turn off.
- Your system is producing weird noises, such as 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 message on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
- The system fan is always running, won’t switch on or turns off and on rapidly in a short period of time.
You might think something is wrong with your heating and cooling system, but if you just got the Nest, we recommend you begin with your thermostat initially. This is especially pertinent if the weather is temperate, and you haven’t been running your heat or air conditioning much.
