2025 Best HVAC Tools List: The 10 Must-Have HVAC Tools for Service Techs

Hammers

Let's start with the hammer, the MVP of your tool belt. Every HVAC technician needs a good carpenter-style hammer for a variety of tasks---whether it's knocking something loose or making sure parts are securely in place. You want to keep it lightweight, though---there's no need to carry around something that weighs you down when you've got a full tool belt to manage. A hammer can be your best friend on the job---so don't skimp on this one.

But here's a pro tip: choose a hammer with a solid grip. You'll be swinging it in all kinds of tight spaces, and the last thing you want is it slipping out of your hand at the worst moment. A hammer that feels comfortable and steady in your grip can make all the difference when you're in the thick of it.
