In the early days, variable-frequency drives (VFDs) were not always reliable. We’re now light years away from the old, unreliable VFD technology. Today's VFDs are smaller, run cooler, are readily available, and their energy-saving performance in air-handling systems is well-known.

On Demand Refrigerant Safety Classes A2L and A3 have a very low GWP, making them a strong, long-term solution for many HVACR applications. However, these refrigerants are classified as mildly flammable and highly flammable respectively. This flammability class raises safety and compliance concerns. This webinar will help you understand these classes, along with the opportunities these refrigerants can offer.

As the HVAC market continues to expand and Variable Refrigerant Flow (VRF) technologies continue to evolve, the demand for contractors with VRF expertise will only grow. This presentation provides thorough insight into the requirements, advantages and opportunities associated with specifying VRF systems and addresses the common misconceptions contractors may encounter in the field.
