Tool manufacturers explain the broad categories of tools that might need an update to comply with new A2L refrigerant systems: leak detectors, manifolds, vacuum pumps, recovery machines, and gauges that can sense R-454B.
Technicians have the choice of using either a digital or mechanical manifold gauge. Each one has its benefits and disadvantages, which is why it may pay to own one of each kind.
Contractors are seeking tools that are equipped to handle A2L refrigerants, offer Bluetooth and wireless compatibility, operate efficiently, save the user time, and are safe to utilize.
