Klein Tools 32613: My Go-To Pocket HVAC Driver
After five years running service calls, I’ve learned that the best tools aren’t always the biggest ones in your bag—they’re the ones you actually have on you when you need them. The Klein 32613 lives in my shirt pocket every single day, and here’s why: it handles about 70% of what I encounter on residential calls without making me dig through my toolbox.
The Phillips and slotted bits are solid for thermostat work and access panels, but the real game-changer is that Schrader bit. Being able to check pressures without switching tools saves me time on every call. The bits lock in tight—no wobble—and the cushion grip actually matters when you’re working in tight spaces all day. It’s not fancy, but it’s earned its spot in my pocket.
