Flashlight

Flashlights may seem basic, but they're essential, especially for HVAC work. You'll often find yourself in tight, dark spaces, and having a reliable flashlight is a lifesaver. Better yet, a headlamp will free up your hands for all the work you're doing. No more juggling a flashlight and tools at the same time!

Pro tip: get a flashlight with long battery life. The last thing you need is to be halfway through a job only to realize your flashlight is dimming. Good lighting is your secret weapon for seeing what's going on in those hard-to-reach corners.
