Basic and Advanced HVAC Tools for Service Technicians


All HVAC technicians require a set of tools to operate at their most optimal. Follow along below as we explain some of the most common HVAC tools and when they will come in handy.


Screwdrivers may seem like an obvious answer. And it is! Screwdrivers are one of the most commonly used tools by HVAC technicians. Panels are often screwed down and you’ll need a screwdriver to get them open. Since the kind of screws will vary between client’s HVAC systems, be prepared with all different types and sizes of screwdrivers. 

When purchasing screwdrivers, keep the quality in mind. Look for stainless steel screwdrivers from trusted brands, like GEARWRENCH, Vickay, or Wera. Investing in a good set of screwdrivers will be worth the investment in the long run — little danger of them breaking in the middle of a job or corrosion weakening them.


Another common tool when it comes to HVAC jobs is a set of pliers. Pliers loosen bolts or hold items in place when cutting or unscrewing panels — a hand tool, indeed.

When you are looking to purchase pliers, ensure that you get insulated ones that are long-lasting. Find pliers that are comfortable to grip, too. 

Be sure to purchase pliers made of stainless steel. It’ll be more doable and resistant to corrosion.


Hammer! Yet another obvious — but essential — HVAC tool. Hammers are versatile. There are many different types of hammers: claw, framing, ball pein, drywall, roofing, brick, tack, drilling, sledgehammer, etc. and so much more. There is a hammer for any occasion!

Hammers are used most commonly to knock in nails. However, hammers can be used to pry, frame, split, round edges, weld, etc. When shopping for your HVAC hammer, pick one that is strong but lightweight. Hammers often come with fiberglass bodies — this ensures the hammer lasts for longer.


HVAC operations typically require working in dark areas. *insert headlamp* Flash lamps are essential to any technician. Headlamps make work easier — allowing the light to shine precisely where you want it. Headlamps also allow you to keep your hands free! No more juggling your hammer, pliers, screwdriver, and lamp in two hands.


When doing piping work, having a variety of wrenches is the way to go. Being prepared with different types will help with all forms of plumbing connections. They come in various sizes and types — it can be hard to know which ones to buy. Check out this Lowes wrench buying guide for help!


Having a thermometer on site is essential for HVAC work. Thermometers help gauge how well an air conditioning system is working. When purchasing one, we’d recommend one with a digital component. Those tend to last longer and deliver more precise readings.
