When I first installed my Nest thermostat, I was pretty nervous about handling the wiring. I remember staring at the exposed wires, wondering if I was about to make a huge mistake. Here’s how I tackled it:

First, I turned off the power to my HVAC system at the breaker box to avoid any electrical mishaps. Safety first! Then, I took a picture of the existing thermostat wiring to ensure I had a reference. This step saved me from a lot of potential confusion later on.

Next, I carefully removed the old thermostat, labeling each wire with the included stickers from the Nest package. The wires were color-coded, which helped, but I made sure to double-check each one against the Nest installation guide. I had a typical setup with wires labeled Y, G, R, and W, which corresponded to the connections on the Nest base.
