Why Your Nest Thermostat Isn't Running Right and How to Solve the Problem

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 by geofencing with your phone, the Nest Learning Thermostat and Nest E realize when you’re at your home or away and can change settings 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 smart idea to check the Nest thermostat compatibility checker before getting one. Don’t forget to check with your energy provider for valuable rebates, since 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 wire it without help or hire a HVAC professional like True Temp Heating & Air Inc. If you’re wiring it yourself, you’ll spot 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 most cases, Nest says this isn’t a setback because the thermostat can get ample power from other heating and cooling wires.

Sometimes, your heating and cooling system might require 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 use 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 turn on your heating and cooling system.

8 Common Nest Thermostat Problems

If it can’t draw enough juice, Nest says you may run into some of these troubles:

  1. Short battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t shut off.
  5. Your system is making weird noises, like chattering, stuttering, clicking or thumping.
  6. Heating or cooling is short cycling, or constantly turning on and off in a short period of time.
  7. There is a delay notice on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly working, won’t turn on or turns off and on rapidly in a short period of time.

You might think something is up with your heating and cooling system, but if you just installed the Nest, we advise 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 frequently.
