  • Klein 935DAA: My Go-To Level for Ductwork Angles

    BySteve

    I’ve been running duct for over a decade, and I can tell you that eyeballing angles doesn’t cut it anymore—especially when you’re dealing with high-efficiency systems where every degree matters. The Klein 935DAA has become my daily driver for setting proper ductwork slopes and checking equipment level. What sold me is how it handles the real-world stuff: the magnetic base actually holds on greasy plenums, the display stays readable even in dim crawlspaces, and those LED alerts mean I don’t have to squint at tiny bubbles while I’m twisted into some awkward position. It switches between 0-90 and 0-180 ranges fast, which is clutch when you’re setting drain pans one minute and checking blower mounts the next. Is it perfect? No. But it’s tough, accurate, and actually makes my job easier—that’s all I need.

  • Klein FLICKBLADE Review: My Go-To HVAC Utility Knife

    ByMike Izzo

    I’ve been running HVAC calls for over a decade, and I’ve burned through more utility knives than I care to count. Most either fall apart after a few weeks or end up buried in my van somewhere when I need them most. The Klein FLICKBLADE changed that for me. This isn’t just another knife with “HVAC” slapped on the box—it’s actually designed for how we work. The folding design means it’s not ripping up my pockets, the built-in scraper handles gasket removal without me fumbling for another tool, and those dual locking positions let me dial in the blade extension I need. Klein included three triple-ground blades that stay sharp through insulation, tape, and cardboard. After six months of daily abuse, it’s still my first grab from the toolbag.
