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 through geofencing with your phone, the Nest Learning Thermostat and Nest E realize when you’re at your home or away and can raise and lower settings to help you save even more.
The Nest works with a wide range of 24-volt heating and cooling systems, but it’s always a smart idea to visit the Nest thermostat compatibility checker before installing one. Don’t forget to check with your energy company for valuable rebates, since you might be able to get a Nest for free or close to it.
Once you’ve made sure it’s compatible, you can either install it without help or call a HVAC professional like Fairfield Heating & Cooling. If you’re wiring 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 a setback as the thermostat can pull adequate 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 Problems
The Google Nest Thermostat is a step up from outdated programmable thermostats that rely on a combination of wiring and AA batteries for power.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 receive adequate juice, Nest says you could run into some of these issues:
- Short battery life.
- Thermostat motion sensing is disabled.
- Your thermostat sometimes disconnects from Wi-Fi.
- Your system abruptly turns on or off, or won’t turn off.
- Your system is producing strange 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, like “heating is delayed for 2:30 minutes.”
- The system fan is always working, won’t turn on or turns off and on repeatedly in a short period of time.
You might think something is up with your heating and cooling system, but if you just got the Nest, we recommend you check your thermostat initially. This is especially pertinent if the weather is temperate, and you haven’t been running your heat or air conditioning consistently.
