List of 20 HVAC tools for technicians


Whether you're a novice or an experienced field technician, having a list of HVAC tools you can refer to will help you stay organized.

Ultimately, there's nothing more frustrating than arriving on site and realizing you don't have the right tools for the job! We've divided our list of 20 HVAC tools into three categories: essentials, special HVAC tools and safety gear. If you're looking for digital tools, consider our extensive list of the 21 best HVAC apps for technicians or the 7 best HVAC apps for growing businesses.

If you're new to the industry, use this list of tools for HVAC technicians as a shopping list. Or, if you already have a toolbox, consider it a checklist to ensure you are fully equipped.


Basic tools that every technician should have


These tools are the foundation of HVAC and a must-have in every technician's toolkit. 



You will always need this kit, which is why it is at the top of our HVAC tools list. A multi-purpose screwdriver with a variety of sizes of magnetic Phillips and flat head bits is ideal. To prevent electric shock, choose a screwdriver with an insulated handle. 



Standard hammers tend to be heavy, so it is best to look for lighter hammers to include in your HVAC tool list. 



Every HVAC technician needs a complete set of pliers to handle bolts and to manipulate and cut wires, cables and pipes. As a minimum requirement, your HVAC tool kit should have the following types of pliers: edging pliers, sharp-nosed pliers, open-end pliers, channel-locking pliers and wire strippers. It is also a good move to keep a variety of sizes. 


Tape measure

A tape measure is an item that you often find yourself using. Although on the surface it may seem like one of the easiest items on a technician's HVAC tool list, there are still some important qualities to check. Penetration, adhesion, adhesion, length, shear and temperature resistance are just a few things to consider. 



A torch is an important tool for HVAC technicians as you will inevitably need to work in areas that are not well-lit. A small handheld torch is a good start, but you'll be glad to have a headlamp as you'll need both hands free. 



Equip yourself with a decent set of crescent spanners, also known as adjustable spanners, which come in a variety of sizes. It would be best if you also had a good pipe spanner to tighten and loosen pipe and gas connections. Include both types of spanners in your HVAC tool list and you can't go wrong!


Cordless drills

The durable, high-performance cordless drill is an essential HVAC tool for field technicians. Drilling holes and driving screws are everyday tasks, so look for lithium-ion battery models that have long run times, are compact, lightweight and comfortable in your hand. 


Manifold gauges

Manifold gauges are an essential item on any decent HVAC tool list. They are used to remove contaminated refrigerant from air conditioning systems, measure the pressure of gases or liquids in cooling systems, detect leaks and test vacuum pressure when charging air conditioning units. 


Special HVAC tools designed for professionals

Now that we have covered the basics, the following items in our technician's list of HVAC tools are designed for more specific purposes.


Glue press guns

Sealing ductwork, joints, cracks and holes are best handled with a caulking gun. This is a pretty standard kit, but some have features such as ladder hooks and finishing tools. 



The Sawzall, also known as a reciprocating saw, is carried by all HVAC technicians. When you need to cut drywall, old condensers, metal or wood, the Sawzall is the tool of choice, which is why it comes second on our list of HVAC tools for professionals. 



An essential part of being an HVAC technician is dealing with temperature regulation and control. So, naturally, you need a thermometer to do your job effectively. Modern thermometers are digital, compact and highly accurate. 


Fin combs

Also known as a fin straightener, this HVAC tool for technicians is used (unsurprisingly) to straighten fins using a combing (brushing?) motion. the movement to straighten the fins. As a secondary benefit, the tool can also remove debris from dirty fins.


Core removal tool

The Core Removal Tool is a handy kit for removing and replacing cores in HVAC systems. To prevent leakage, the cores must be properly tightened after reinstallation, so a tool with an integrated torque mechanism to help with this process is ideal. 



As an HVAC technician, you will often be removing water from cooling systems. To perform this task, a vacuum pump is essential. 


Safe HVAC tools


These may not be the most exciting pieces of equipment, but they are the most important items on our technician's HVAC tool list. 



In the United States alone, an estimated 2,000 workers suffer eye injuries on the job and need medical attention every day! The most frustrating part? The right pair of glasses could have prevented 90% of these injuries. If only they had consulted this list of HVAC tools 

So, choose your safety glasses carefully. Look for models with ridges to keep sweat out of your eyes, and always check that they meet the latest industry standards.



Your hands are probably the most important tool, so make sure you take care of them! That's why gloves are one thing you don't want to miss on your list of essential HVAC tools. 

Today, you can purchase HVAC gloves that are flexible enough to perform small and tedious tasks, but still provide effective warmth and protection.

Many modern gloves even have fitted fingertips so you don't have to take them off to use your smartphone. Now that's handy! 


Ear protection

When things get noisy, you'll want to shut out some of the sounds. Both earplugs and ear muffs are fine, just make sure you choose a product with the right decibel (dB) rating. 

It's also wise to consider the ambient temperature of your working environment. Tip: Discard earmuffs at temperatures above 80°F.



Work boots with a steel toe are usually the most sensible choice. The soles should be slip-resistant and provide grip on most surfaces. If you spend a lot of time climbing ladders, high-heeled boots are best: you can get a safer position on each rung. 



To protect yourself and those around you, you must wear a mask - especially indoors. 



As a diagnostic and safety tool, a multimeter can test the current and measure the voltage. It is vital to ensure that this information does not accidentally electrocute you while working.
