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 realize when you’re at your home or away and can raise and lower settings to help you save even more.
The Nest can be used with a full range of 24-volt heating and cooling systems, but it’s always a smart idea to check the Nest thermostat compatibility checker before purchasing one. Don’t forget to contact your energy company 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 wire it without help or contact a HVAC professional like Connolly Electric & Mechanical. If you’re putting it in yourself, you’ll spot a terminal for the C-wire, or common wire. This wire is just 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 get ample power from other heating and cooling wires.
Sometimes, your heating and cooling system could have to have that C-wire. And here’s why.
Why Your Nest Keeps Losing Power and Other Issues
The Google Nest Thermostat is a step up 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 sync with Wi-Fi, power its digital display and run your heating and cooling system.
8 Common Nest Thermostat Issues
If it can’t draw enough electricity, Nest says you may encounter some of these issues:
- Poor 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 making odd noises, like 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 message on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
- The system fan is continuously on, won’t switch on or turns off and on frequently in a short period of time.
You could think something is wrong with your heating and cooling system, but if you just started using the Nest, we advise you start with your thermostat right away. This is especially pertinent if the weather is temperate, and you haven’t been using your heat or air conditioning much.
