The Nest thermostat is one of the most popular smart thermostats you can get. 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 realize when you’re at your residence or away and can raise and lower settings to help you save even more.
The Nest can be used 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 contact your energy supplier for valuable rebates, because you may be able to get a Nest for free or close to it.
Once you’ve confirmed it’s compatible, you can either wire it yourself or hire a HVAC professional like Wallpe Heating & Cooling. If you’re installing it without help, you’ll spot a terminal for the C-wire, or common wire. This wire is only 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 an issue since the thermostat can get adequate power from other heating and cooling wires.
Sometimes, your heating and cooling system may have to have that C-wire. And here’s why.
Why Your Nest Keeps Losing Power and Other Problems
The Google Nest Thermostat is a step up from outdated programmable thermostats that have a combination of wiring and AA batteries for power. It uses a rechargeable lithium-ion battery and wiring to link to Wi-Fi, power its digital display and turn on your heating and cooling system.
8 Common Nest Thermostat Issues
If it can’t draw adequate power, Nest says you could encounter some of these troubles:
- Poor battery life.
- Thermostat motion sensing won’t operate.
- Your thermostat every now and then disconnects from Wi-Fi.
- Your system abruptly turns on or off, or won’t turn off.
- Your system is making weird noises, such as 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 constantly working, won’t run or turns off and on rapidly in a short period of time.
You could think something is suspect with your heating and cooling system, but if you just installed the Nest, we advise you start with your thermostat right away. This is especially true if the weather is mild, and you haven’t been relying on your heat or air conditioning consistently.
