Why Your Nest Thermostat Isn't Running Right and How to Repair It

April 13, 2021

The Nest thermostat is one of the best-selling smart thermostats on the market today. And for good reason. It learns your temperature preferences and develops an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your home or gone and can adjust temperatures to help you save even more.

The Nest can be used with a vast range of 24-volt heating and cooling systems, but it’s always a good idea to use the Nest thermostat compatibility checker before purchasing one. Don’t forget to contact your energy provider for valuable rebates, since you might be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either hook it up on your own or hire a HVAC pro like Assured Appliance and Heating & Air. If you’re wiring it yourself, you’ll see 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 a problem as the thermostat can get adequate power from other heating and cooling wires.

In some instances, your heating and cooling system could 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The Google Nest Thermostat is a step up from outdated programmable thermostats that rely on a combination of wiring and AA batteries for power.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 sync with Wi-Fi, power its digital display and turn on your heating and cooling system.

8 Common Nest Thermostat Issues

If it can’t get ample juice, Nest says you may encounter some of these troubles:

  1. Short battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t stop running.
  5. Your system is producing weird noises, like chattering, stuttering, clicking or thumping.
  6. Heating or cooling is short cycling, or frequently turning on and off in a short period of time.
  7. There is a delay notice on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is always running, won’t turn on or turns off and on rapidly in a short period of time.

You may believe something is up with your heating and cooling system, but if you just installed the Nest, it’s best to begin with your thermostat right away. This is especially timely if the weather is temperate, and you haven’t been running your heat or air conditioning consistently.
