The Nest thermostat is one of the best-selling smart thermostats you can buy. And for good reason. It picks up on your temperature preferences and creates an energy-efficient schedule to match. And using geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your residence or gone and can raise and lower temps 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 smart idea to use the Nest thermostat compatibility checker before installing one. Don’t forget to talk with your energy company for valuable rebates, because you might be able to get a Nest for free or close to it.
Once you’ve checked it’s compatible, you can either hook it up on your own or call a HVAC specialist like Air Service Co.. If you’re installing it on your own, you’ll see a terminal for the C-wire, or common wire. This wire is solely used for powering your thermostat. If your home or HVAC system is older, you might not have one of these wires. In the majority of cases, Nest says this isn’t an issue as the thermostat can get adequate power from other heating and cooling wires.
In some cases, 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The Google Nest Thermostat is an improvement from outdated programmable thermostats that have a combination of wiring and AA batteries for power. It has 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 draw adequate electricity, Nest says you might run into some of these problems:
- Poor 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 producing odd 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 notice on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
- The system fan is continuously running, won’t turn on or turns off and on repeatedly in a short period of time.
You could believe something is wrong with your heating and cooling system, but if you just installed the Nest, we suggest you start with your thermostat first. This is especially true if the weather is temperate, and you haven’t been relying on your heat or air conditioning much.
