Hand Tools

Pretty much every trade has its own specialized set of hand tools that are essential to the work. There is some overlap, however. For instance, some hand tools that are important for HVAC work are also used in plumbing. You will see what we mean in a moment as we highlight some of the essential hand tools every HVAC technician should be equipped with:

  • Shears – Cutting into sheet metal is a big part of HVAC installation and repair as vent work commonly needs to be altered in some way. Steel shears are essential to make long, straight cuts into sheet metal and if you can, find a good pair with an insulated handle.
  • Aviation Snips – For cutting into ductwork more comfortably when a curve is needed, aviation snips are crucial. As the name suggests aviation snips were originally developed to cut metal for aircraft. But now they are a staple in the HVAC industry for making curved cuts into ductwork and cuts that require a change of direction at some point. 
  • Tin Snips – Tin snips (both left and right) make cutting into round ductwork much easier. They will help your technicians make longer, straighter cuts into ductwork which is usually required when making an HVAC system more energy-efficient or watertight. 
  • Pipe Wrench – This is one of the tools that a plumber and HVAC technician will likely have in their bag. HVAC appliances like gas furnaces and water heaters are hooked up to utility lines. As an HVAC contractor or technician, you will have to connect and disconnect these lines on service calls. A good pipe wrench therefore cannot be overlooked. The best pipe wrenches have ductile iron handles that will actually bend before they break. They last a long time and they give you a warning before they completely fail.

Refrigerant Scale

The career of an HVAC technician is essentially a prolonged practice is precision. Measurements of all kinds in HVAC need to be precise. Refrigerant is no exception. Putting too much refrigerant can put undue strain on an air conditioner’s compressor. Putting too little will render the system incapable of maintaining the desired temperature. A refrigerant scale is therefore needed to carry out service calls and detect leaks the right way. A good scale will allow you to use exactly the right amount of refrigerant so you won’t have to make a second service call for the same problem.

Voltage Meters

Think voltage meters are only used by electricians? Think again. Voltage meters are yet another tool that is extremely important in multiple trades. Voltage meters allow you to test for live wires and outlets before working on them. They will also allow your technicians to see if systems are putting out the amount of energy needed to power certain HVAC systems. Voltage meters are therefore very important for the safety of your team and to help them diagnose and fix common HVAC problems. 

Vacuum Pumps

Vacuum pumps allow your technicians to suck out moisture and air out of ductwork. Why is this important? It’s important for maintenance and cleaning jobs but also for leak testing. Vacuum pumps can help your technicians pinpoint a line leak before they do something like charge the system with refrigerant; saving lots of time, money and risk.


A good cordless drill goes a long way in the HVAC industry. Make sure your team is equipped with cordless drills with all the necessary bits. One of the most important parts of a drill kit that many HVAC contractors overlook is a drill bit sheath. A drill bit sheath can help your technicians avoid puncturing holes in refrigerant lines when installing test ports. A drill bit sheath will also help prevent creating leaks in the ductwork that can throw off static pressure readings. At any rate, it is also a good idea to ensure that all your technicians have at least 2 batteries on hand for their drill to make sure they will be able to complete all-day projects.

Top HVAC Tool Brands

Now that you know what types of tools you need, you should consider the top brands for HVAC tools. After all, a tool is only as good as its manufacturer. Trust is probably the number one consideration for contractors looking to invest in heating and cooling tools, especially when it’s for their business and employees. Let’s take a look at some top brands:

Milwaukee Tool

Milwaukee tool is considered one of the most trustworthy brands for HVAC. They’ve been in business since 1924 which gives contractors an idea of how reliable they are in the marketplace. They are known for appealing directly to “real users” rather than just marketing their tools to anybody. Milwaukee makes trade-specific equipment that is built for durability.


Fieldpiece is near and dear to the HVACR community. They make hand-held test instruments that are crafted specifically for HVAC contractors. They were the first to offer modular expandability, which allows for contractors to test the majority of parameters with only a single meter. The HVACR powerhouse now offers additional tools such as manifolds and scales.


Hilmor is another popular brand for HVAC tools. They are known as one of the more innovative manufacturers and provide considerable value to contractors. Whether you are looking for gauges, hoses, manifolds, or another type of equipment, Hilmor is going to provide a solution, and an innovative one, at that. Check out their duel readout thermometer.
