6 Different Necessary Tools For Repairing An AC


HVAC service and installation of new air conditioners for residential and commercial clients necessitate a skilled workforce. Furthermore, having access to the proper HVAC tools and equipment is essential for completing the job.

You’ll need tools if you’re just starting out as an HVAC service technician. It ranges from the bare necessities to those that are nice to have but are not required. If they don’t even have a basic set of tools, to begin with, it’s a good indication that they aren’t as dedicated to the craft as they claim.

Major and prevalent tools used for servicing AC

In electrical appliances, there are many tools available for servicing and repairing. Each serves a different purpose and function. For servicing portable air conditioners or HVAC systems, technicians utilize various tools or devices. They usually come up with their own toolbox when going to their job, otherwise, some residents provide their tools to help the technician. So, below are some common and principal tools used in AC services.

Reciprocating saw blades

A reciprocating saw blade, such as the Sawzall, is the best saw for cutting through materials in most HVAC jobs. That’s why HVAC contractors employ this. The Sawzall is extremely durable, and it has endured the test of time. These saws are unique and available with a specific purpose in mind.

These saws can usually cut drywall, pipes, wood, old condensers, or sheet metal without changing power tools. Typically, the HVAC Company provides the blades so that the technician can keep the saw sharp. Because dull blades can muck up a job and make it take longer.

HVAC software

Mobile software is becoming an increasingly important part of the HVAC technician’s toolkit. HVAC software and a mobile app enable the technician to provide accurate estimates in a timely manner. This also allows for easy communication with the business office or with consumers.

With an HVAC software and mobile app solution, you could get all of this and much more. It helps to manage every aspect of your HVAC business more efficiently. This frees up your technicians’ time and energy to focus on their work rather than on time-consuming administrative tasks. HVAC software enables you to reconfigure your expanding business and take it to the next level.

Online scheduling, dispatching, estimating, and invoicing make it easier to run your HVAC Company. Instead of rushing back to the office to look at paper files or make calls, they can get it with a tap of the screen.

Refrigerant scale

A refrigerant scale assists in addressing issues by measuring the weight of refrigerant as it is added to or removed from the compressor of the unit. This provides your technician with the necessary information to put in exactly as much as the system requires. A refrigerant scale eliminates the guesswork involved in charging a system with refrigerant.

While charging the system, technicians use a refrigerant scale to accurately gauge the levels of freon or other refrigerants. The scale assists technicians in locating leaks or performing routine maintenance on these systems.

Technicians put a refrigerant cylinder on the weighing platform of a refrigerant scale to use it. A series of tubes or cables connect the cylinder to the system, allowing refrigerant to pass between the air conditioner and the cylinder. Rechargeable battery packs or a power cord can be used to power a refrigerant scale. It depends on how much mobility the user requires.

Multimeter or voltage tester

One of the most important HVAC technician safety tools is the multimeter. It detects electrical current and alerts you if the voltage is present. It protects you from electrocution. To detect electrical currents on wires, switches, or outlets, you may apply the multimeter.

Autoranging meters measure the magnitude of the voltage. It will also automatically select the range with the most significant digits on the display. When measuring current, however, you should set the mode to resistance, volts, or current and connect the probe leads to the appropriate sockets.

It is critical to test for safety when working near electrical hazards and live wires. Keep a multimeter in your toolbox to test for the presence and voltage of electricity.

Wrenches, cutters, pliers

Any comprehensive HVAC tool kit will include a variety of wrenches, ranging from fixed and adjusted to crescent and pipe wrenches. To handle any job, keep small, medium, and large wrenches in your HVAC toolbox. Wrenches should come in a variety of sizes, as well as a pipe wrench for gas lines.

Keep a set of pliers on hand for smaller connections and better wiring manipulation. It includes needle-nose, channel-lock, open-face, wire strippers, and linesman pliers. Using insulated-handled pliers reduces the risk of electrical shock.

HVAC metal and tubing cutters are useful for cutting through anything on the job. Start with a smaller set of cutters, such as quarter-inch or half-inch cutters, when you first start your HVAC career. However, as you proceed to handle a broader range of projects, you should add a broader set of cutters.

Drill and gauges

Because of its portability, power, and versatility, a cordless drill is an essential HVAC tool. Keep a charging battery in your toolbox so that your technicians never run out of drill power on the job. Keep at least two batteries on hand to ensure that your technician’s drill lasts the entire day without needing to be recharged.

For an HVAC technician, cordless, battery-powered drills are extremely useful in the field. Because you’ll be using it frequently, you’ll want a drill that is both reliable and durable.

Refrigeration gauges are essential for your service technicians. Professional technicians use gauges to identify pressures for various types of refrigerants and to determine whether there is a leak in the system. As your career progresses, you may require multiple gauge sets. One of these tools is the manifold gauge. In the past, manual gauges were used, but newer digital gauges have become more popular.


In conclusion, the vital information of this topic is to give the crucial tools for repairing or servicing an AC. For the maintenance of an air conditioner, there are various tools that technicians or electricians employ. Having an AC in your home is not a bad thing, but having proper service and maintenance is essential for a good function. Sometimes, AC shows some problem or troubleshoots, so repairing is necessary. For example, if there is a problem with the Leaking air conditioner, refrigeration gauges are a suitable tool for this issue. The other tools are also very useful in other problems. if you don’t have your personal technician, then make sure you have your proper toolbox for repairing an AC.
