So if you want the latest features and technology, upgrading makes sense. Use the specs above to decide which upgraded Nest best fits your home.

Switching Smart Thermostat Brands

Alternatively, you may decide to replace Nest with a different brand of smart thermostat entirely:

• Ecobee SmartThermostat
• Honeywell Home T9
• Emerson Sensi Touch

Top reasons you may want to switch brands include:

• Better compatibility with your HVAC system
• Specific features like remote sensors or built-in Alexa
• Subscription model vs one-time purchase

Make sure to compare all specs, capabilities, and integrations to select the right smart thermostat for your home.

Below we’ll cover HVAC system compatibility in more detail when troubleshooting wiring issues with Nest.

Troubleshooting Nest Issues

If your current Nest thermostat develops technical problems, removing and reinstalling the device can often resolve bugs or glitches:

• Restarts the software and hardware
• Resets wired connections
• May fix firmware problems

Before factory resetting or removing Nest though, first try basic troubleshooting steps like adjusting temperature calibration or testing the built-in diagnostics.

However if you’re still experiencing issues with your thermostat like connectivity problems, strange readings, or frozen screens, fully removing then reattaching the device typically resolves software bugs.

Remodeling Living Spaces

Finally, if you‘re planning renovations to the areas around your thermostat like:

• Repainting walls a new color
• Installing new drywall
• Swapping out trim materials

Removing your Nest device gets it safely out of the way during construction and remodeling.

Just make sure to clearly label wires and take photos of the existing setup beforehand as we’ll cover below.

Now let’s get into the step-by-step process for properly taking a Nest Learning Thermostat off your wall.

Safety First: Preparing to Remove Nest

Before physically detaching Nest from the wall mount or disconnecting any wires, there are two crucial safety steps:

Turn Off Power at the Circuit Breaker

The first and most important preparation step is to cut power to your HVAC heating/cooling system at the main circuit breaker:

1. Find the circuit breaker box, usually located in basement, garage, or utility closet

2. Open the metal door and locate the switch controlling your HVAC system wires

3. Flip switch to fully cut power to HVAC and Nest device

According to EnergyStar guidelines, turning off the power is “the most important thing to remember” when changing any wiring.

Without power disabled “even a slight touch of the wrong wire can result in personal injury”. So always turn off the circuit breaker as the first step.

Photograph Wiring Connections

Before actually detaching any of the wired connections to your HVAC system, thoroughly photograph the setup.

Be sure to capture:

• Each wire terminal labeled with the wire name
• Any bundled cables
• The unique wiring order of your HVAC system

Having photos lets you easily reconnect wires properly during reinstallation.

You can also refer to the nest wiring diagram located on the back of your specific thermostat or in the Nest app:

• Tap Menu > Settings > Installation Settings > Wiring diagram

Now with power disabled and existing wiring documented, let’s remove Nest.

Step 1: Detach Nest From Wall Mount

The first removal step is gently pulling the Nest thermostat off the wall mount:

1. Grip edges of the Nest device avoiding any buttons / screens

2. Slowly pull Nest straight away from mount until magnets release

3. Don’t twist or forcefully pry during removal

If it doesn’t detach easily first try, confirm power is still disabled via circuit breaker.

There can sometimes be dust buildup on the pins or residual power left in capacitors.

Once you verify power is certainly off, attempt gently removing again. The key is pulling directly away from wall without excessive force.

Step 2: Disconnect Wiring from terminals

With Nest separated from wall mount, we can begin safely disconnecting the wiring terminals:

1. Use a Phillips screwdriver to loosen each screw along wire terminals

2. One-by-one gently detach wiring from base plate ports

   • Pull wires straight out with steady pressure
   • Don’t yank hastily to avoid copper damage

3. As you remove each wire, wrap the metal end around itself so copper doesn’t accidentally touch and short circuit against other wires or the mount

4. Label wires with painters tape as they are removed if diagram is unclear

Depending on your HVAC system and installer, you may have different connections. But common configurations are:

• Rc: Cooling power
• Rh: Heating power
• W1: Heat relay
• Y1: Compressor relay
• G: Fan relay
• C: Common wire

Refer to the wiring diagram for your specific system when detaching wires.

Step 3: Remove Wall Mounting Plate

Finally, with all wiring detached, remove the actual wall mount anchoring your Nest:

1. Unscrew mount from the wall and pull away
2. Remove any remaining trim pieces
3. Use drywall putty on screw holes and repaint

And just like that – you’ve fully removed Nest from the wall!

Step 4: Restore Circuit Breaker Power

With Nest thermostat successfully taken off the wall along with all connected wiring, restore power:

• Return to your circuit breaker box
• Flip the HVAC switch back to ON

Electricity will resume flowing to your heating/cooling system.

Now let’s reset and remove Nest from your account if you’re upgrading or replacing models.

Resetting and Removing Nest from Account

If your reason for removal is either upgrading to a newer Nest model or switching smart thermostat brands:

1. First reset your old device
2. Then disconnect Nest from your Google account

Here is the process for each:

Factory Reset Nest Before Reuse

Resetting your Nest deletes all your connected settings and returns it to out-of-box conditions:

1. On thermostat select Settings > Reset

2. Choose “Factory Reset”

   

3. One last confirmation that you want to erase all customizations

4. Device will restart with welcome setup flow

Resetting clears any strange cached data or bugs that may be causing issues and lets you reuse Nest on a different HVAC system if needed.

Removing Nest from Your Google Account

Finally, if fully retiring your Nest smart thermostat, disconnect it from your account:

1. In Nest mobile app tap the Settings icon

2. Select “Your Products”

3. Choose the Nest you’re removing

4. Tap “Remove Product”

   

5. Confirm again you want to disconnect Nest from account

Once removed, your thermostat won’t pull data from your account even after factory resetting.

Troubleshooting Common Nest Removal Problems

While removing Nest is typically very straightforward, below we cover solutions for a few common issues:

Power Won’t Cut Off

If you flip the circuit breaker switch but Nest still seems to have power, there may be wiring problems in your breaker box.

Consult a certified electrician to properly disconnect power before continuing removal.

According to 2021 research from Neato Home Care, the average cost to replace an outdated breaker box is $950.

While fixing Nest compatibility issues specifically averages around $250.

Wall Mount Won’t Detach

Sometimes dust, grime, or paint can make separating the thermostat from wall anchors difficult.

Use a plastic 5-1 painters tool to gently pry multiple areas loose. Slowly work mount free by applying careful pressure across entire surface rather than one spot.

Be cautious not to further damage wall or surrounding mount area as excess drywall repairs drives up costs. Painters putty to patch holes runs approximately $10 per tub according to Home Depot.

Broken Wiring in Terminals

As wiring ages, copper strands can occasionally snap when removing from ports. This leaves partial bits stuck.

• Use needle nose pliers to fully extract broken remnants
• Ensure no copper strands touch other terminals
• Trim wire end with sharp wire cutters
• Check HVAC system functionality once reconnected

Broken thermostat wiring can disrupt communication between your Nest device, HVAC components like furnace or AC unit, and the transformers powering each.

If system problems persist after reinstallation, you may need to replace the wiring cable itself. According to 2021 data from Modernize, homeowners paid an average of $196 to replace thermostat wiring.

Let’s Recap: Key Takeaways

To quickly recap, here are the key steps and safety tips for properly removing any Nest Smart Thermostat:

1. Disable power at circuit breaker before any removal

   • Avoid electric shock risk
   • Let capacitors discharge

2. Photograph wiring terminals

   • Simplifies reconnecting later

3. Pull Nest straight off wall mount

4. Disconnect wires mindfully
