Smart tools continue to grow in the HVACR industry, spurring manufacturers to create connected, digital devices that will make work in the field less manual and more automatic.

While “smart” tools and tablets are becoming more and more common in an HVAC tech’s toolbox, there are still plenty of things an app just can’t do.

The HVAC TRMS Digital Multimeter helps professional HVACR technicians and installers diagnose complex electrical systems, test flame sensors, and measure temperatures.

Technology is redefining how consumers control their homes. That includes everything from lighting to mood music to heating and air conditioning.

How does a tech know the a/c compressor he or she is diagnosing is actually failed and that the problem is not a crankcase heater, condenser fan, or rubbed out wire?

There’s no doubt that Internet of Things (IoT)-enabled technology has impacted the HVACR industry. Now, the technology is evolving even further, allowing HVACR manufacturers to include built-in diagnostics and troubleshooting in the equipment itself.

I see techs in the field get the most frustrated when they have a low-voltage short they can’t seem to locate. The challenge techs face with low voltage diagnosis is a combination of poor process and some root misunderstanding about what they are looking for.

HVACR technicians are special individuals. They have the intelligence, aptitude, and knack for problem-solving. In fact, they are expected to know how to diagnose and troubleshoot equipment of all types, sizes, and ages.

The air duct calculator, or “ductulator,” is a commonly used tool for designing and installing duct systems. Unfortunately, many designers and technicians receive limited instructions on its correct use.
