It's not hard if you take your time.

*** It's advisable to always find the breaker for your system and turn of the power. However, the little wires are low voltage (24 volts) and won't hurt you. But still...

Tip number one, make sure you mark on the old thermostat where each wire goes before you disconnect, they are usually four different colors.

Two, if your phone takes pictures, take a couple pictures.

Three, bring your old unit with you to the hardware store, and your camera phone pictures.

They should be able to tell you anything you need to know.

Bring home the replacement, attach wires as directed.

Good luck!

ETA, there are great videos on youtube, find the right one!
