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

The Nest thermostat is one of the most popular smart thermostats you can get. And for good reason. It learns your temperature preferences and creates an energy-efficient schedule to match. And using geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your home or away and can adjust settings 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 wise idea to use the Nest thermostat compatibility checker before purchasing one. Don’t forget to check 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 checked it’s compatible, you can either hook it up yourself or contact a HVAC specialist like Speedy Air Conditioning. If you’re wiring it without help, you’ll see a terminal for the C-wire, or common wire. This wire is just used for powering your thermostat. If your residence 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 adequate power from other heating and cooling wires.

In some cases, your heating and cooling system might need that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Problems

The Google Nest Thermostat is an improvement from aging programmable thermostats that have a combination of wiring and AA batteries for power. It relies on a rechargeable lithium-ion battery and wiring to link to Wi-Fi, power its digital display and run your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t get ample juice, Nest says you could have some of these issues:

  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 shut off.
  5. Your system is making odd 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 notification on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly on, won’t switch on or turns off and on frequently in a short period of time.

You might worry something is up with your heating and cooling system, but if you just started using the Nest, we recommend you begin with your thermostat initially. This is especially pertinent if the weather is temperate, and you haven’t been relying on your heat or air conditioning consistently.
