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 makes an energy-efficient schedule to match. And by geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your residence or away and can change settings to help you save even more.
The Nest works with a vast range of 24-volt heating and cooling systems, but it’s always a good idea to visit the Nest thermostat compatibility checker before purchasing one. Don’t forget to check with your energy provider for valuable rebates, because you could be able to get a Nest for free or close to it.
Once you’ve checked it’s compatible, you can either wire it on your own or call a HVAC specialist like Titan Heating & Air Conditioning. If you’re putting it in without help, you’ll see 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. In most cases, Nest says this isn’t an issue since the thermostat can pull ample power from other heating and cooling wires.
Sometimes, your heating and cooling system might have to have that C-wire. And here’s why.
Why Your Nest Keeps Losing Power and Other Malfunctions
The Google Nest Thermostat is better than 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 Problems
If it can’t draw adequate power, Nest says you may have some of these problems:
- Short battery life.
- Thermostat motion sensing won’t operate.
- Your thermostat sometimes disconnects from Wi-Fi.
- Your system abruptly turns on or off, or won’t turn off.
- Your system is making weird noises, including chattering, stuttering, clicking or thumping.
- Heating or cooling is short cycling, or constantly turning on and off in a short period of time.
- There is a delay message on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
- The system fan is continuously on, won’t run or turns off and on frequently in a short period of time.
You might think something is up with your heating and cooling system, but if you just started using the Nest, we suggest you begin 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 consistently.
