The Nest thermostat is one of the most popular smart thermostats you can get. And for good reason. It picks up on your temperature preferences and makes an energy-efficient schedule to match. And using geofencing with your phone, the Nest Learning Thermostat and Nest E realize when you’re at your residence or away and can change temperatures to help you save even more.
The Nest is compatible with a full range of 24-volt heating and cooling systems, but it’s always a good idea to check the Nest thermostat compatibility checker before installing one. Don’t forget to check with your energy supplier 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 hook it up yourself or hire a HVAC specialist like County Line Mechanical LLC. If you’re putting it in without help, you’ll spot a terminal for the C-wire, or common wire. This wire is just used for powering your thermostat. If your residence or HVAC system is older, you might not have one of these wires. In the majority of cases, Nest says this isn’t a setback since the thermostat can get adequate power from other heating and cooling wires.
Sometimes, your heating and cooling system may require that C-wire. And here’s why.
Why Your Nest Keeps Losing Power and Other Problems
The Google Nest Thermostat is an improvement from aging 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 Malfunctions
If it can’t get enough juice, Nest says you might have some of these problems:
- Short battery life.
- Thermostat motion sensing won’t work.
- Your thermostat every now and then disconnects from Wi-Fi.
- Your system suddenly turns on or off, or won’t shut off.
- Your system is making odd noises, like 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 constantly running, won’t run or turns off and on rapidly 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 begin with your thermostat initially. This is especially true if the weather is temperate, and you haven’t been relying on your heat or air conditioning consistently.
