This guide covers 50 of the best HVAC tools that service techs need to provide high-quality service to customers. Our list and descriptions of the best HVAC tools solve even the most complex HVAC problems as efficiently as possible and give your customers a highly professional service and experience.
The list is broken down into two main categories:
1. Manual and calculation tools that HVAC service techs need to do their work:
2. Software tools to run an HVAC service business — including marketing to get more leads, accounting, payroll, and dispatching, along with tools to help techs in the field do their job more efficiently and profitably.
The list of essential tools focuses on the manual hand tools and calculators every HVAC tech needs on the job, and the list of software tools is made up of those ServiceTitan has designed to help business owners manage and grow their HVAC businesses. As a tech, you can ask your manager about software tools that will help you do your job more efficiently.
We’ll start with the manual HVAC tools list, with gear that service techs need to provide the most professional customer experience.

Make sure you have a range of screwdrivers in different sizes and with extensions so you can maneuver really small screws and work in tight spaces. In addition, you will of course need a complete set of nut drivers in your tool bag.
An HVAC tech needs to be ready to handle most sizes of wires, bolts, and pipes with a full set of pliers. Get small, medium, large, and needle-nose pliers. You will also need an insulated set of pliers for durability and longevity.
Of course, every HVAC technician needs a standard-size hammer for various uses on the job. We suggest a lightweight hammer with an easy grip and fiberglass construction for convenience and durability.
HVAC service techs always need a reliable flashlight to accurately assess heaters and air conditioning. Headlamps also come in handy to keep your techs’ hands free when working in dark spaces.
Any complete HVAC tools list includes a wide range of wrenches, from fixed and adjustable to crescent and pipe wrenches. Keep small, medium, and large wrenches in your HVAC toolbox to handle any job, as well as pipe wrenches to loosen pipe connections.
Metal and tubing cutters (such as tin snips) are essential HVAC tools to cut through anything on the job. We suggest starting with a smaller set in the beginning of your HVAC career, such as quarter-inch or half-inch cutters, but add a wider set of cutters as you progress to handling a wider scope of projects.
Note: A wire cutter can be bought with a wire stripper as an all-in-one tool (e.g. Klein Tools ).
A cordless, battery-powered drill is another essential tool that gives your service techs more versatility. Keep a charging battery in your toolbox so your techs never run out of drill power while on the job site. We recommend a cordless drill with at least 24 volts and various bits.
When it comes to air conditioning tools, refrigeration gauges or manifold gauges are must-haves for service techs. Gauges are used to measure the pressure of different types of refrigerants and determine whether there’s a leak in the system. Multiple sets of gauges may be needed, as techs’ careers progress and they sharpen their skills.
Fieldpiece is a popular brand for gauges among many HVAC professionals.
Extension cords are tool kit basics for HVAC techs to plug in electric tools when working onsite. Look for a long, thick cord that’s not too bulky to transport. We suggest 50 feet as an optimal length.
Keep a staple gun on your HVAC tools list to secure joists and foil lines for increased air flow, and to properly assemble ductwork.
A tape measure is an essential HVAC technician tool. It will be in use daily for measuring walls, pipes, hoses, and everything in between, so make sure you buy a good quality one that’s 25 feet long.
Protecting your service techs’ health and safety on the job, as well as your HVAC customers, is a top priority. Here are some specific safety items to include on your complete HVAC tools list.
Buy a pair of durable, nimble gloves that are thick enough to protect your hands, but allow enough dexterity to hold screws and smaller tools. HVAC service techs wear gloves every day, especially as Personal Protective Equipment during challenging times.
Wearing masks while performing HVAC work also provides personal protection for your techs and customers. Make sure your techs keep a stash of masks in their trucks to use for every job.
Safety goggles protect your eyes from metal and dust debris. Some goggles or safety glasses with magnification also allow techs to see smaller parts of the job for better accuracy and efficiency.
Using power tools in close proximity and closed quarters puts a huge strain on your ears and your hearing. Protect your ears with industrial-strength ear muffs or plugs.
Working on ladders all day, and in other people's homes, requires your service techs to be prepared to negotiate various types of terrain. Make sure they’re equipped with a pair of heavy steel-toe work boots that won't slip and protect their feet in case something heavy drops on them.
These HVAC tools fall into the category of more advanced and expensive but are important nonetheless. HVAC companies typically provide these specialty tools to help keep their customers’ HVAC equipment in good working order.
HVAC tools such as a core removal tool come to the rescue in many cases. When dealing with broken cores, this tool assists your techs with removal and replacement.
A coil fin straightener helps to clear debris when air conditioner condenser coils get dirty, clogged, or twisted. Service techs use this air conditioning tool to straighten and clean the coils to improve heat exchange (hex) and air flow. These air conditioning tools are inexpensive and extremely useful.
Temperature control matters the most in the HVAC industry. Invest in a digital thermometer that’s portable, effective, and long lasting to follow your state’s regulations and deliver awesome customer service.
An HVAC technician uses a manometer to measure system air pressure in heating, ventilation, and air conditioning systems. Available in analog and digital, it can also check airflow and pressure in ducts and across filters and coils.

This tool also acts as a safety device. When working near electrical hazards and live wires, it’s important to test for safety. Keep a multimeter in your toolbox to test for the presence of electricity and to check voltage.
HVAC contractors consider a reciprocating saw blade, such as the Sawzall, to be the best saw to cut through materials in most HVAC jobs. Durability is crucial, and the Sawzall stands the test of time. The blades need to be replaced regularly to avoid dull blade use.
A dripless caulking gun allows you to seal air ducts and fill holes where needed. Keep your caulking gun in good working order to avoid future messes.
Your HVAC vacuum pump needs to be powerful enough to remove any moisture from the lines.
A nitrogen regulator acts as a pressure control valve. It reduces highly pressurized gas or liquid into a more usable form. Without a nitrogen regulator, the high pressure allows the gas or liquid to be released all at once.
HVAC service techs use refrigerant leak detectors to confirm areas with moisture. This device acts as a tester to identify the source of a refrigerant leak.
A refrigerant scale is used to measure the weight of the cylinder in a refrigerant cylinder. This helps HVAC techs accurately measure the weight of refrigerant when carrying out refrigerant recovery during repairs and replacements of air conditioning units.
Psychrometers measure and rate the airflow and air mixtures. The psychrometer also measures relative humidity.
Hand seamers give your techs the power to bend or flatten sheet metal by hand. Snips allow them to easily cut sheet metal to size. Once again, insulated grips make both jobs easier.
A crimper allows techs to wrinkle certain types of metal to make them conform to the next section of piping.
Flaring tools allow HVAC techs to make a mechanical joint that joins or seals copper tubing. Sometimes used in tandem with swaging tools, HVAC technicians can create a flare connection and connect tubes to one another or to other fittings.
Yellow Jacket is a popular brand for flaring and swaging tools.
HVAC techs use the awl to score sheet metal so they can cut it straight. Awls are also used to punch holes in sheet metal, wood, or sheetrock when necessary.
HVAC technicians need to diagnose complex problems for clients based on very general information. Thermal imaging cameras, an essential HVAC tool, enable techs to accurately identify and fix the root causes in short order.
As refrigeration lines age, obstructions within the line become more likely. Keeping a flushing solvent on hand helps to quickly clear contaminants from the line and keeps your customers’ appliances working as efficiently as possible.
No matter which HVAC app you choose to use to streamline your workflow, you’re definitely going to want to bookmark this handy ServiceTitan HVAC Load Calculator.

The HVACR Fault Finder troubleshooting app makes it easy for your techs to problem-solve compressor electronic system failures. You can choose to enter a flashing “alert” code or use the “tap” feature to identify the code from the electronic module. The code gives you access to its interactive troubleshooting guide, which they can browse for tips and tricks to solve the problem. HVAC Fault Finder also gives you electronic product manuals and videos to help discover and then solve the problem at hand.
