The Nest thermostat is one of the best-selling smart thermostats on the market today. And for good reason. It figures out your temperature preferences and develops an energy-efficient schedule to match. And using geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your home or away and can change temperatures to help you save even more.
The Nest can be used with a vast range of 24-volt heating and cooling systems, but it’s always a wise idea to check the Nest thermostat compatibility checker before installing one. Don’t forget to contact your energy provider for valuable rebates, as 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 contact a HVAC pro like AC Sales. If you’re putting it in without help, you’ll notice 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. In the majority of cases, Nest says this isn’t an issue because the thermostat can draw ample power from other heating and cooling wires.
Sometimes, your heating and cooling system may need that C-wire. And here’s why.
Why Your Nest Keeps Losing Power and Other Malfunctions
The Google Nest Thermostat is an improvement from older programmable thermostats that rely on a combination of wiring and AA batteries for power. It has a rechargeable lithium-ion battery and wiring to sync with Wi-Fi, power its digital display and operate your heating and cooling system.
8 Common Nest Thermostat Malfunctions
If it can’t receive enough electricity, Nest says you might run into some of these problems:
- Short battery life.
- Thermostat motion sensing is disabled.
- Your thermostat sometimes disconnects from Wi-Fi.
- Your system suddenly turns on or off, or won’t shut off.
- Your system is producing odd noises, including 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 working, won’t turn on or turns off and on frequently in a short period of time.
You could believe something is up with your heating and cooling system, but if you just started using the Nest, we suggest you check your thermostat right away. This is especially timely if the weather is moderate, and you haven’t been relying on your heat or air conditioning consistently.
