The Nest thermostat is one of the best-selling smart thermostats you can buy. And for good reason. It learns your temperature preferences and makes an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your residence or away and can change temperatures to help you save even more.
The Nest is compatible 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 purchasing one. Don’t forget to check with your energy provider for valuable rebates, as you could be able to get a Nest for free or close to it.
Once you’ve confirmed it’s compatible, you can either install it on your own or hire a HVAC specialist like Assured Appliance & Heating & Air. If you’re wiring it yourself, you’ll notice 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. Most of the time, Nest says this isn’t a setback as the thermostat can draw enough power from other heating and cooling wires.
In some cases, your heating and cooling system might require that C-wire. And here’s why.
Why Your Nest Keeps Losing Power and Other Malfunctions
The Google Nest Thermostat is an improvement from outdated programmable thermostats that rely on a combination of wiring and AA batteries for power.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 run your heating and cooling system.
8 Common Nest Thermostat Issues
If it can’t draw ample electricity, Nest says you might encounter some of these troubles:
- Bad battery life.
- Thermostat motion sensing won’t work.
- Your thermostat every now and then disconnects from Wi-Fi.
- Your system abruptly 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 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 repeatedly in a short period of time.
You could believe something is wrong with your heating and cooling system, but if you just started using the Nest, we advise you check your thermostat right away. This is especially timely if the weather is temperate, and you haven’t been relying on your heat or air conditioning much.
