The Nest thermostat is one of the most popular smart thermostats you can buy. And for good reason. It learns 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 home or gone and can change temps to help you save even more.
The Nest works with a full range of 24-volt heating and cooling systems, but it’s always a smart idea to check the Nest thermostat compatibility checker before getting one. Don’t forget to check with your energy provider for valuable rebates, as you may be able to get a Nest for free or close to it.
Once you’ve made sure it’s compatible, you can either hook it up without help or contact a HVAC professional like SchagrinGAS Company. If you’re installing it without help, you’ll spot 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. Most of the time, Nest says this isn’t an issue as the thermostat can get enough power from other heating and cooling wires.
In some cases, your heating and cooling system may have to have that C-wire. And here’s why.
Why Your Nest Keeps Losing Power and Other Issues
The Google Nest Thermostat is an improvement from aging programmable thermostats that use 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 operate your heating and cooling system.
8 Common Nest Thermostat Issues
If it can’t get enough electricity, Nest says you may run into some of these troubles:
- Bad battery life.
- Thermostat motion sensing is disabled.
- Your thermostat every now and then disconnects from Wi-Fi.
- Your system unexpectedly turns on or off, or won’t shut off.
- Your system is making weird 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 notification 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 might believe something is up with your heating and cooling system, but if you just installed the Nest, we recommend you begin with your thermostat right away. This is especially timely if the weather is mild, and you haven’t been running your heat or air conditioning consistently.
