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 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 are aware of when you’re at your residence or away and can adjust temperatures to help you save even more.

The Nest is compatible with a wide range of 24-volt heating and cooling systems, but it’s always a good idea to check the Nest thermostat compatibility checker before purchasing one. Don’t forget to contact your energy company for valuable rebates, since you may be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either wire it yourself or contact a HVAC pro like Air Quality Solutions. If you’re wiring it yourself, you’ll see 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 as the thermostat can get 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 Issues

The Google Nest Thermostat is an improvement from aging 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 operate your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t receive adequate juice, Nest says you might encounter some of these issues:

  1. Bad battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t shut off.
  5. Your system is creating 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 message on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly running, won’t switch 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 got the Nest, we advise you start with your thermostat initially. This is especially timely if the weather is temperate, and you haven’t been relying on your heat or air conditioning frequently.
