A Complete List of HVAC Tools That Technicians Should Include in 2023

1. Multimeter

You probably don’t want to experience an electric shock, right? So, a multimeter is a must-have safety tool for HVAC technicians. This instrument checks electrical current and shows if any voltage is present and thus preventing you from being electrocuted. Whenever you are on-site to inspect any HVAC equipment, this tool must accompany you. It can detect currents on wires, outlets, or switches.

2. Safety goggles

Safety goggles are an essential HVAC tool for your HVAC job. Having accurate vision while working is crucial. There will be metal and dust debris on your HVAC job site. So, to protect your eyes, you must have a pair of safety goggles.

Here is a cool tip, invest in goggles with magnification that helps you see smaller parts of the HVAC units.

3. Gloves

No, that random gloves you see in stores won’t help. You must invest in a pair of durable, high grip gloves as they are your personal protective equipment for your hands. The gloves must be thick enough to safeguard your hands and flexible enough to hold screws and smaller tools comfortably. 

4. Work boots

HVAC jobs demand a lot of standing. So, to protect your foot and make you feel comfy, work boots are another HVAC safety tool necessary for HVAC technicians.

5. Earplugs

This tool is often overlooked. If you don’t want your hearing sense to be affected while using power tools, ear plugs are essential. So make sure to protect your ears using industrial-strength ear plugs or muffs.

6. Core removal tool

Another must-have tool for an HVAC technician is the core removal tool which assists with the removal and replacement of broken cores.

7. Coil fin straightener

Air conditioner condenser coils are often prone to clogging, getting dirty, or twisted. So to clean it up, you need a coil fin straightener. This is one of the best tools that helps HVAC service technicians straighten and clean the coils to improve airflow and heat exchange.

8. Thermometers

The HVAC industry is all the temperature, isn’t it? So, temperature control is another crucial aspect, and investing in a digital thermometer is recommended. Just ensure it is portable and effective enough to last long.

9. Saw

A saw is another important tool in the HVAC technician tool list. But you need a reciprocating saw blade such as the Sawzall to do the job correctly. An HVAC technician uses a saw blade to cut through different materials like metal, steel, and plastic. When choosing the saw, ensure it is durable and if it stands the test of time.

10. Nitrogen regulator

The gas tanks with CO2 and nitrogen combo tend to be in extremely high pressure. So, a regulator is used to lower that pressure to a stable level before the gas reaches the keg. Without such a regulator, the high pressure can cause the gas or liquid to be released all at once. It is another essential tool in your HVAC toolkit. 

11. Leak detector

Just like any other technology, HVAC systems too age, and they develop wear and tear after certain years of use. So, the systems start to leak. While dealing with refrigerants, HVAC technicians use refrigerant leak detectors to check different areas with moisture to identify the source of a refrigerant leak. 

12. Psychrometer

A psychrometer is a tool that helps in measuring humidity by calculating both a wet-bulb and a dry-bulb temperature reading. With these two values, this tool can accurately calculate the other properties of the air, including its moisture content, the rate of airflow, and air mixtures in the HVAC system.

13. Caulking gun

The dripless caulking gun helps an HVAC technician seal air ducts and fill holes in the HVAC unit. So, this HVAC tool must be taken care of and keep it in good working order to avoid future messes.   

14. HVAC software

This is not a physical tool, but to level up your HVAC business as a business owner or contractor, or technician, you need an HVAC software tool. There are multiple software tools to help in field management, accounting, invoicing, estimating HVAC load calculators, and another such tasks in HVAC businesses.

15. Recovery unit

The refrigerant recovery machine helps the HVAC technician extract refrigerant per EPA standards. This machine helps to conduct work on air conditioning refrigerant pipes, such as checking for leaks, which is quite helpful. So, this is another must-have major HVAC tool in your HVAC toolkit. 

16. Vacuum pump

Vacuum pumps are HVAC specialty tools to service any air conditioning unit. Once you extra the refrigerant using the recovery machine, this HVAC tool helps prevent water vapor and air from entering the refrigerant line.

Though it is an expensive HVAC tool, it is important to have one to get the job done correctly. This type of HVAC tool is given to HVAC technicians by their employers. 

17. Digital weight scale

To perform maintenance or installs in a new HVAC unit, HVAC techs need a digital refrigerant scale. 

When the refrigerant is pulled from the line set, a weight scale is used to check the amount of refrigerant. The pipe may have potential leaks if there is a low reading. 

18. Oxy/Acetylene torch kit

Brazing and soldering are two important tasks while installing the HVAC unit. So, an HVAC tool list is incomplete without Oxy/Acetylene torch kit. This tool helps connect and solder the line set to the compressor and other parts of the HVAC unit.

This tool helps the service technicians get the job done fast, but you must use the torch carefully as it can easily damage the pipes if used wrongly. 

19. HVAC technician tool list

HVAC service technicians must maintain a proper balance of airflow in the air ducts to ensure the system’s efficiency. So, to measure the static pressure within the HVAC unit’s ductwork, one needs a manometer.

20. Screwdrivers and nut drivers

There is no HVAC tools list without screwdrivers and nut drivers. In fact, these are the basic HVAC hand tools that help HVAC technicians prepare for the job properly. That said, a full range of screwdriver bits and nut drivers is recommended. 

If not a full-range screwdriver, get hold of a multi-purpose screwdriver with a Philips-head but and a flathead bit in sizes 1 and 2, provided with a small magnetic nut driver set.

21. Tape measure

Another simple yet important HVAC tool that helps measure the refrigerant pipe or sheet metal ductwork tape measure. Check if it comes with a self-locking mechanism so that it can help you during a work call, and impact resistance goes a long way.

22. Pliers

You need a full set of pliers to handle wires, bolts, and pipes of different sizes. Getting small, medium, large, and needle-nose pliers are recommended. Investing in an insulated set of pliers can give you durability and longevity.

23. Hammer

A standard-size hammer is a potential HVAC tool for an HVAC service technician that must accompany them for every HVAC job. Ensure it’s lightweight, easy to hold, and has a fiberglass construction to enjoy convenience and durability.

24. Extension cords 

Yes, your tool bag must also include an extension cord. Because these extension cords are necessary to plug in the electric tools while working onsite. So, what to look for while investing in one?

Check if the extension cord is thick, long, and portable. In terms of length, we suggest 50 feet. 

25. Gauges

GGauges are an essential HVAC tool that is used to measure different types of refrigerants and find out if an HVAC unit has leaks or not. So, when repairing air conditioning units, you need refrigeration or manifold gauges. 

26. Flashlight/Headlamp

To accurately assess the heating and air conditioning of an HVAC system, HVAC technicians must carry a flashlight or headlamp. In particular, a headlamp is handy as you can walk free, working in a dark space conveniently. 

27. Drills and cutters 

You need a cordless, battery-powered drill to drill holes to fix the HVAC units, and we did mention it is a cordless drill because it will help you be more efficient. However, have a charging battery in your toolbox, so charge the drill that runs out of power.

To cut through anything, you need metal and tubing cutters. If you are a beginner, start with a quarter-inch or half-inch cutter, and with time, start handling wide-sized cutters. 

28. Wrenches

The HVAC tools list is incomplete without wrenches. They are available in different sizes and shapes for fastening, turning, tightening, gripping, and loosening things such as pipe, nuts and bolts, and pipe fittings.

You need a wide range of wrenches, from fixed and adjustable to crescent and pipe wrenches, for your HVAC job. Ensure to have small, medium, and large wrenches to handle any job and pipe wrenches to loosen the pipe connections.
