A Comprehensive List of Must-Have HVAC Tools for Technicians

Complete HVAC Tools List

Having the right set of HVAC tools is paramount to being able to get the job done properly.

Your HVAC tools list determines what kinds of jobs you can take on and how efficiently you can handle them.

Whether you’re starting a new HVAC business or want to expand your operations, the first modus operandi is to have the right HVAC technician tool list.

To help you out, here is our complete list of advanced and basic tools for HVAC technicians.

Basic HVAC Tools

Standing out from the competition means having expert technicians equipped with the best tools to handle any job.

Here is the essential HVAC tools list that every technician needs.


The addition of a full range of screwdrivers is imperative. HVAC professionals often require the help of a screwdriver for a range of tasks. Make sure your team has a full set of screwdrivers to choose from, including Phillips, flathead, and hex styles.


When it comes to HVAC must-have tools, you simply can’t get by without a hammer, this is the most versatile and widely used tool on any handyman’s belt.

Having a range of hammers in different sizes is ideal. (Specifically, a classic Stanley hammer with its iconic yellow handle).


Pliers are some of the most important basic HVAC tools. This is because HVAC systems often connect to plumbing, which means technicians need to handle wires.

Having both wire and needle nose pliers will ensure that your crew can easily cut and maneuver wires during routine maintenance, installation, and repairs.

Like screwdrivers and pliers, all HVAC professionals should be equipped with a range of wrenches, including crescent and pipe wrenches. Pipe wrenches are especially useful when dealing with gas lines and plumbing pipe connection maintenance and repairs.


Metal and tubing cutters are perfect for slicing through anything standing in the way of a job well done. You’ll want to start out small at the beginning (¼ inch – ½ inch for fledgling technicians) but as your business grows, expanding your selection will be beneficial.

Flashlight And Headlamp

Headlamps are particularly useful as they leave your hands free while working, this is especially important when working in dark spaces.


HVAC technicians often need to cut through drywall, condensers, sheet metal, or wood. These HVAC hand tools make this easy.

Coil Fin Straightener

This is the perfect tool for cleaning and unclogging AC condenser coils, improving heat exchange and airflow in HVAC systems. This should be a staple in a technician’s toolkit.

Heavy-Duty Extension Cord

Your ability to have convenient outlets available while you work may be hindered depending on your client’s home.

Make sure you’re able to easily use the tools you need without worrying about power by adding a heavy-duty extension cord to your toolkit.


Drills are a vital requirement on your HVAC tool list. Try to get both a cordless and corded drill to be covered for all scenarios.

Metal Crimper

A handy tool for cutting, stripping, and crimping metal.

Hand Seamer
