This guide covers 46 of the best HVAC tools service techs need to provide a high-quality service to customers. Our list and descriptions of the best HVAC tools to have on hand to serve homeowners 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 (nut drivers, gauges and more):

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 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.

Essential HVAC Tools

1. Screwdrivers and Nut Drivers

To be properly prepared for the job, keep a range of screwdrivers and nut drivers in your tool bag. We suggest a multi-purpose screwdriver with at least a Phillips-head bit and a flathead bit in sizes No. 1 and No. 2, along with a small magnetic nut driver set. However, a full range of screwdriver bits and nut drivers would be a wise investment.

2. Pliers

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. We also suggest investing in an insulated set of pliers for durability and longevity.

3. Hammer

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.

4. Flashlight/Headlamp

HVAC service techs always need a reliable flashlight to accurately assess heating and air conditioning. Headlamps also come in handy to keep your techs’ hands free when working in dark spaces.

5. Wrenches

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.

6. Cutters

Metal and tubing cutters are useful 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.

7. Drills

A cordless, battery-powered drill gives your service techs more versatility for better efficiency. Keep a charging battery in your toolbox so your techs never run out of drill power while on the job site. We recommend a drill with at least 24 volts and various bits.

8. Gauges

When it comes to air conditioning tools, refrigeration gauges or manifold gauges are a must-have 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.

9. Extension Cords

HVAC techs need extension cords 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..

10. Staple Gun

Keep a staple gun on your HVAC tools list to secure joists and foil lines for increased air flow, and to properly assemble ductwork.

HVAC Tools for Safety

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.

11. Gloves

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.

12. Masks

Wearing masks while performing HVAC work also provides personal protection for your techs and customers. Now considered essential PPE, make sure your techs keep a stash of masks in their trucks to use for every job.

13. Goggles

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.

14. Ear Muffs/Plugs

Using power tools in close proximity and closed quarters puts a huge strain on your ears and impacts your hearing. Protect your ears with industrial strength ear muffs or plugs.

15. Shoes

Working on ladders all day, and in other people's homes, requires your service techs to be prepared to traverse 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.

Advanced HVAC & Air Conditioning Tools

These HVAC tools fall into the category of more advanced and expensive but are important nonetheless. HVAC companies typically provide these advanced tools to help keep their customers’ HVAC equipment in good working order.

16. Core Removal

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.

17. Coil Fin Straightener

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 and air flow. These air conditioning tools are inexpensive and extremely useful.

18. Thermometers

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.

19. Multimeter

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.

20. Saw

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.

21. Caulking Gun

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.

22. Pumps

Your HVAC vacuum pump needs to be powerful enough to remove any moisture from the lines.

23. Nitrogen Regulator

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.

24. Leak Detector

HVAC service techs use refrigerant leak detectors to confirm areas with moisture as a way of identifying the source of a refrigerant leak.

25. Psychrometer

Psychrometers measure and rate the air flow and air mixtures. The psychrometer also measures relative humidity.

26. Hand Seamers and Snips

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.

27. Crimper

A crimper allows techs to wrinkle certain types of metal to make them conform to the next section of piping.

28. Awl

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.

29. Thermal Imaging Tools

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. 

30. Flushing Solvent

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. 

HVAC Calculator Apps for Techs in the Field

31. ServiceTitan’s HVAC Load Calculator

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.

Tools to Grow HVAC Business Revenue

34. Call Booking Tool for HVAC Services

ServiceTitan’s call booking tool helps HVAC businesses organize their call booking processes, and ultimately book more jobs by providing a framework to follow for every incoming call. The process can be repeated for every call so that nothing is missed and customers are given a professional experience whenever they get in touch.

The booking tool includes a cloud-based phone system, which helps HVAC businesses streamline and speed up their call booking process. Customer service reps (CSRs) answering calls get a heads up about who exactly is on the other end of the line and can greet each customer by name. 

Our software also provides drop-down menus of easy-to-follow prompts for customer service reps (CSRs) to make sure they ask for all pertinent information before the call ends.

ServiceTitan records every incoming call so both CSRs and techs can listen to the exact conversation the customer had and check on the details given.

35. HVAC Marketing Tool

ServiceTitan’s marketing tools are designed to help you grow your HVAC business faster by generating more leads. 

Our local service ad tool, for example, helps your business show up in more Google searches when local customers search for your service. ServiceTitan also guides customers to book an appointment with you directly through Google ads. It also keeps track of which ads and calls actually made you money and rank campaigns by how much income they generated, so you can make decisions about how to spend your ad budget.

Our marketing ROI tool, on the other hand, serves as a dashboard or scorecard that monitors which ad campaigns are working, how many leads they are generating, at what cost, and more. It also has a heat map that can show you which geographical areas are bringing in the most business (as shown in the above image) by intensifying the color of each area based on revenue, so you can identify where to double down on promoting your services. This helps you increase the ROI on your marketing spend by doing more of what’s working and less of what’s not.

36. Memberships and Contracts Tool

Manage recurring jobs, like regular HVAC maintenance, using ServiceTitan’s service agreement software. It allows you to easily convert single visits into regular contracts and bring in more revenue from what would otherwise be a one-off booking. 

We provide you with an easy-to-follow wizard to set up maintenance contracts in just a few clicks, even while your tech is still at the job site. You get to apply discounts and schedule regular appointments far into the future, making it easier to turn up to every single service visit and avoid overbooking.

Contracts can be customized to the specifics of each of your HVAC customers. You can adjust monthly fees, add extra maintenance tasks, and upgrade for extra services. 

Meanwhile, ServiceTitan will also cost all labor and materials, which avoids invoicing errors and ensures all your costs are covered.

Tools to Manage HVAC Service Operations

37. HVAC Scheduling Tool

ServiceTitan’s Service Scheduling Software makes it simple to schedule HVAC visits in advance. When you know which jobs are coming up in the next few days, weeks, or months, it’s more straightforward to make sure that the right techs are available on those days. 

Knowing that some portion of your visits are guaranteed, the software also provides your business with a greater degree of financial stability.

You can schedule in longer time slots for more complex jobs that are coming up and add tags for the technical specifications of every job. This helps you to send out an HVAC technician who is qualified and ready to deal with the job. Plus, your techs will know exactly what to expect when they arrive at the customers’ premises and have the right tools on hand to finish the job that day.

38. HVAC Dispatching Tool

Our field dispatch software helps you send your HVAC techs to each of their jobs on time. ServiceTitan’s smart schedule optimization adjusts for longer-than-expected visit times, traffic, and other delays in real-time. You can extend or shorten the time allotted for each job as these changes happen.

ServiceTitan also sends out job confirmations and other appointment notifications directly to the customer by text message. This feature cuts out the need for confirmation calls to customers, and significantly reduces no-shows.

39. HVAC Payroll & Timesheet Tool

We’ve designed ServiceTitan’s Contractor Payroll Software for home services contractors to effortlessly manage payroll, pay staff correctly and on-time, and to see how profitable their business is at a glance. 

Monitor timesheets while including overtime, commissions, and bonuses earned. Each individual timesheet shows you how long your techs spend on essential tasks, including driving to and from visits, time spent buying materials, and time spent working on every job.

40. Mobile App & Tablet

Make it easy for customers to order, buy, and pay for your company’s HVAC services with a simple tap, click, or swipe on a mobile tablet. 

Using ServiceTitan’s Mobile App, techs build tiered estimates out in the field with access to vibrant photos, manufacturer videos, and detailed product information, so customers can browse and buy at their own pace — just like shopping online.

Give your HVAC customers the mobile-driven service they prefer by adding ServiceTitan’s Mobile App to your techs’ arsenal of tools. Other key features include:
