Make sure you show up to each job well prepared. With our guide, you can stock up your truck with the best tools for the job. Here are the top 5 tools for cold side HVACR techs to get you started.

Gauges

• What it does and why you need it – Gauges are essential for making sure you have the proper amount of refrigerant to charge a system. They can also help you to diagnose if the issue with the unit is internal, leaving out any guess work.
• Types of gauges – As with most tools, there are analog and digital options available. The one you buy will be based on your preference.
• What to look for – If you want a gauge to do the math for you, digital is the way to go. If you prefer the old fashioned way, then an analog gauge will get the job done.
• Tips for using gauges – When testing multiple units, use different gauges to avoid cross-contaminating refrigerants.

Vacuum Pump

• What it does and why you need it – Vacuum pumps are used to remove gas and other impurities in the system when changing out refrigerants or doing a fresh install.
• What to look for – When searching for a vacuum pump, look at reviews from certified technicians to see which pump will be more efficient and last longer.
• Tips for using vacuum pumps –  It’s important to stay on top of maintenance. This means changing the oil when needed and making sure it’s working properly before using it on a unit.

Scale

• What it does and why you need it – Scales are a great tool that can weigh refrigerant to help you add the correct amount into a system.
• Types of scales – There are both analog and digital scales available.
• What to look for – Look at reviews to ensure they remain accurate for a long period of time and won’t need constant recalibration.
• Tips for using scales – Make sure it’s not placed with other tools and is kept in a place where it doesn’t get banged around.

Torches

• What it does and why you need it – HVAC torches are used for brazing copper fittings together, creating a tight seal.
• Types of torches – When it comes to torches, there are two types available. These include signal acetylene tanks and combination oxygen acetylene tanks.
• What to look for – If you need something with more precision that can work well in tight spaces, then the combination oxygen acetylene tank is the one to choose. For something quick in a spacious area, a single tank will work perfectly.
• Tips for using torches – The most important thing to remember when using torches is remembering your safety gear. Having gloves, goggles and other protection will keep you safe on the job. Also, when storing them away, be sure that they’re closed off tightly to avoid leaks.

11-in-1 Screwdriver

• Types of 11-in-1 screwdrivers – There are HVAC-specific screwdrivers as well as electrician-specific screwdrivers, ratcheting models and more available.
• What to look for – Make sure when shopping for one that you shop for your specific application to ensure you get the correct bits you need.
• Tips for using 11-in-1 screwdrivers – Always have this tool on hand. If you have a tight space where a larger tool may not fit, this tool can help you reach the area you need to get into.
