Pliers

Pliers are your go-to multitasker. From wire strippers to needle-nose to channel-lock, each type of plier is built for something specific. Needle-nose pliers, for example, are perfect for grabbing small wires when you're working on a thermostat. But no matter what kind you choose, insulated handles are a must to keep those nasty electrical shocks at bay.
A solid plier set is a must-have for almost every HVAC task, so make sure you've got a set that includes all the essentials. Whether you're bending, cutting, or gripping something tight, pliers will be right there with you. Don't leave home without them!
