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

April 13, 2021

The Nest thermostat is one of the top-selling smart thermostats on the market today. And for good reason. It picks up on your temperature preferences and develops 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 adjust temps 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 use the Nest thermostat compatibility checker before purchasing one. Don’t forget to talk with your energy supplier for valuable rebates, as you may 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 contact a HVAC specialist like Honke Heating & AC. If you’re wiring it yourself, you’ll see a terminal for the C-wire, or common wire. This wire is solely used for powering your thermostat. If your house or HVAC system is older, you might not have one of these wires. In most cases, Nest says this isn’t a problem because the thermostat can pull adequate power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is an improvement from outdated programmable thermostats that have a combination of wiring and AA batteries for power.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 Problems

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

  1. Short battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t turn off.
  5. Your system is making strange noises, like 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 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 frequently in a short period of time.

You could believe something is suspect with your heating and cooling system, but if you just installed the Nest, we suggest you check your thermostat initially. This is especially true if the weather is mild, and you haven’t been relying on your heat or air conditioning much.
