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

April 13, 2021

The Nest thermostat is one of the most popular smart thermostats you can buy. And for good reason. It figures out your temperature preferences and makes an energy-efficient schedule to match. And using geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your home or out and about and can raise and lower temperatures 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 wise idea to visit the Nest thermostat compatibility checker before purchasing one. Don’t forget to contact your energy supplier for valuable rebates, as you could be able to get a Nest for free or close to it.

Once you’ve confirmed it’s compatible, you can either install it yourself or contact a HVAC specialist like Airmen HVAC Service. If you’re putting it in yourself, you’ll notice a terminal for the C-wire, or common wire. This wire is just 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 since the thermostat can draw ample power from other heating and cooling wires.

Sometimes, your heating and cooling system could need that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Problems

The Google Nest Thermostat is better than older programmable thermostats that rely on a combination of wiring and AA batteries for power. It relies on 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 Malfunctions

If it can’t receive adequate electricity, Nest says you might run into some of these issues:

  1. Poor battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t turn off.
  5. Your system is creating strange noises, including chattering, stuttering, clicking or thumping.
  6. Heating or cooling is short cycling, or repeatedly turning on and off in a short period of time.
  7. There is a delay notification on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously on, won’t switch on or turns off and on frequently in a short period of time.

You may think something is wrong with your heating and cooling system, but if you just got the Nest, we suggest you begin with your thermostat right away. This is especially timely if the weather is mild, and you haven’t been using your heat or air conditioning consistently.
