The Nest thermostat is one of the top-selling smart thermostats you can buy. And for good reason. It picks up on your temperature preferences and creates 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 out and about and can raise and lower temps 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 smart idea to use the Nest thermostat compatibility checker before getting 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 made sure it’s compatible, you can either hook it up on your own or contact a HVAC specialist like MPC Heating & Cooling. If you’re installing it without help, you’ll spot 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. In most cases, Nest says this isn’t an issue because the thermostat can draw enough power from other heating and cooling wires.
In some instances, 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 better than older programmable thermostats that use a combination of wiring and AA batteries for power. It relies on a rechargeable lithium-ion battery and wiring to connect to Wi-Fi, power its digital display and turn on your heating and cooling system.
8 Common Nest Thermostat Problems
If it can’t draw ample power, Nest says you could encounter some of these problems:
- Short 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 shut off.
- Your system is creating weird noises, including chattering, stuttering, clicking or thumping.
- Heating or cooling is short cycling, or repeatedly turning on and off in a short period of time.
- There is a delay notification on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
- The system fan is always running, won’t turn on or turns off and on repeatedly in a short period of time.
You may believe something is up with your heating and cooling system, but if you just started using the Nest, we advise you begin with your thermostat right away. This is especially true if the weather is moderate, and you haven’t been using your heat or air conditioning consistently.
