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 you can get. And for good reason. It figures out your temperature preferences and creates an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E realize when you’re at your house or out and about and can adjust temperatures to help you save even more.

The Nest works 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 check with your energy provider 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 hook it up without help or contact a HVAC professional like Kowalski Heating, Cooling & Plumbing. If you’re putting it in yourself, you’ll spot a terminal for the C-wire, or common wire. This wire is only used for powering your thermostat. If your home 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 because the thermostat can draw enough power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is better than outdated programmable thermostats that have a combination of wiring and AA batteries for power. It has 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 Problems

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

  1. Bad battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t turn off.
  5. Your system is making weird noises, such as 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 message on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously working, won’t switch on or turns off and on frequently in a short period of time.

You might think something is suspect with your heating and cooling system, but if you just started using the Nest, we suggest you start with your thermostat first. This is especially pertinent if the weather is temperate, and you haven’t been using your heat or air conditioning consistently.
