HVAC safety tools

Repairing HVAC units can be dangerous. Chemical exposure, electrical hazards, and unsuitable tools can all cause accidents.

Here are some of the best tools to help protect your team while fixing HVAC units. 

(By the way, consider buying them from Malco — it has built a name for its high-quality products.)

• Gloves: Gloves are a simple yet effective tool that can help safeguard hands from sharp objects or toxic chemicals. Buy a tough-yet-flexible pair that doesn’t restrict movement.
• Shatter-proof goggles: Safety goggles protect eyes from sparks, debris, and dust. You can also buy advanced goggles that come with magnification options to help improve accuracy.
• Durable footwear: Apart from preventing foot pain, sturdy HVAC boots also help keep you safe. Look for boots that are water resistant to help handle damp conditions. The soles should have good grip and thickness to prevent slipping and protect feet from punctures. The boot should also have insulating rubber that can withstand electric shocks. 
• Hard hat: HVAC repair technicians should wear hard hats or helmets to protect themselves from falling or flying objects or electrical burns at the job site.
• Ear protection: The US Occupational Safety and Health Administration (OSHA) requires workers to use protection when sound levels are above 90 decibels in a day. Using ear plugs and earmuffs can keep your team comfortable during loud noises and prevent hearing loss while working on tough jobs. 
• Comfortable overalls: Overalls (or, if you’re feeling funky, yellow jackets) are a practical option for HVAC service techs. Besides offering comfort, they also protect the skin from chemical or electrical burns.
• Multimeter: Invest in a reliable multimeter to accurately check the volt output and the presence of electrical currents. 

HVAC software tools

The right software tools can make managing your HVAC business simpler. Here’s a run-through of some effective software worth considering.

• Circuit for Teams for route planning: Circuit for Teams can help you create and optimize driver routes so your service techs spend more time on the job, saving you time and money. 
• Jobber for managing payments: Jobber can help you manage payments so your team is paid faster. It offers contactless payment options for your customers with no hidden fees.
• FreshBooks for accounting: An accounting software like FreshBooks reduces the stress of balancing your books and managing salaries and incomes and allows you to create financial reports.
• Mailchimp for email marketing: Nearly 72% of small businesses use email marketing to communicate with their customers. Feature-rich email marketing software like Mailchimp can make the process quicker and help you sell more services.
• Broadly for building an online reputation: Online reviews are crucial for any business. They help you improve your services, build your company’s reputation, and attract potential customers. They also give difficult customers an outlet to give constructive feedback. Broadly helps you manage online reviews and improve the customer experience through its easy-to-use platform.
• WordPress or Squarespace to design a website: A professional website can give your business more credibility, establish your brand’s presence, and help you get more leads. Creating a website is easier than ever with template-based options from platforms like WordPress or Squarespace.

HVAC hand tools

It’s impossible to picture an HVAC service tech without their hand tools. A variety of hand tools are available for different purposes. 

Here are some your employees should have in their toolboxes.

• Screwdrivers: There are six commonly used types of screwdrivers. It’s probably worth getting a multi-purpose one that works with a variety of screw sizes. The Phillips head bit and flathead bit are also helpful.
• Pliers: A sturdy pair of pliers is essential for your team. Use needle-nose pliers to grab wires while working on thermostats. Make sure the pliers you hand out have insulated handles.
• Wrenches: A complete set of different-sized wrenches can equip your team to complete many tasks quickly. Pipe wrenches and crescent wrenches are important for repairing HVAC systems.
• Crowbar: Use a crowbar to pull two objects apart without too much energy.
• Flashlight: Invest in a quality flashlight to help your team work under dim lighting conditions. You can also get a headlamp to free up their hands.
• Battery-powered drill: A cordless, battery-powered drill can be a convenient power tool for your workers. It’s a tool they’ll use regularly, so make sure you get a durable one.
• Hammer: Keep a lightweight hammer with a good grip in each tool bag for removing nails or installing new components in a system.
• Utility knife: Use this small tool to open boxes, cut insulation, and do other everyday tasks. Replace the blades once they start to get dull.
• Pipe calibers: Use these to measure pipe sizes accurately.
• Sheet metal shears: Use these to cut holes in metal ductwork. If you don’t know which size to get, go for 12-inch shears with a 3-inch bite.
• Pipe and tube cutters: Your team members may need to cut through copper and PVC tubes and pipes while repairing HVAC units. Get a small cutter for pipes under 1.25 inches and a large tubing cutter for pipes up to 1.75 inches.
• Fuse puller: This is the correct tool to safely remove a fuse from its holder.
• Inspection mirror: HVAC service techs often need to read information or inspect joints at the back of a pipe that can’t be seen with the naked eye. Your team members can tilt an inspection mirror to a suitable angle to see behind pipes and look into crevices.
• Long-neck net driver set: A set of long-neck nut drivers can help your workers get into tight spaces while fixing HVAC units. You should get a variety of sizes, including one-quarter inch, five-sixteenths of an inch, three-eighths of an inch, and one-half inch.
• Staple gun: A heavy-duty staple gun is ideal for fastening many materials. HVAC service techs can use outward clinch staples for securing insulation around duct pipes.
• Crimping tool: You can use a crimper to attach two wires or reduce the diameter of thin pipes and ducting.

HVAC utilities

Apart from the hand tools, HVAC service techs also require some basic utilities. Check their tool kits regularly to make sure they haven’t run out.

• Magnetic level: Checking the leveling of equipment before installing it can save your team the time and effort of straightening it out later. A magnetic level is ideal for installing thermostats.
• Tape measure: A tape measure is a basic but essential part of a complete HVAC toolkit. You should get one that measures 25 feet and have team members learn how to use it properly.
• Extension cord: Use heavy-duty extension cords when equipment wiring can’t reach the nearest power outlet.
• Duct tape: Use tape to fix just about anything. Aluminum foil tape is the right choice for repairing HVAC units since it’s flame and humidity resistant and can withstand extreme temperatures.
• Screws: Keep a set of different-sized screws in stock when heading to a repair job.
• Caulk and a dripless caulking gun: Use a dripless caulking gun for filling holes and sealing ducts.
• Step ladder: While most customers have a ladder at home for your team to use, it’s better to be prepared and keep one in your van in case they don’t.
• Markers: You can use black permanent markers to make a record of your service or maintenance or to mark measurements on pipes.

Advanced HVAC tools

Now that you have your basics in place, consider investing in a few advanced HVAC tools.

While you don’t need to own all of these, getting the ones suitable for your team’s needs can make them more efficient. 

Here are some of the best HVAC tools for specialized purposes.
