Zaretsky Engineering Solutions Joins Johnson Controls-Hitachi Manufacturers’ Sales Rep Team

May 28, 2019

Johnson Controls-Hitachi is pleased to announce that Zaretsky Engineering Solutions will be the new manufacturers’ representative for Hitachi Variable Refrigerant Flow (VRF) systems and SmartFlex™ Mini-Split systems in southern California, including the Los Angeles and San Diego markets.

Hitachi VRF systems offer engineers, mechanical contractors, and building owners a cost-effective and energy-efficient HVAC choice with multiple advantages which include:

  • A modular design that enables systems to be customized to each project’s exact requirements. Options include heat pump and heat recovery systems and a host of fan coil choices.
  • Design freedom. Options include ducted systems with short or long runs as well as non-ducted systems that require much less plenum space (reducing construction costs and increasing alternatives).
  • Energy savings, on average, up to 39% compared to conventional systems.
  • Impressively quiet, personalized comfort delivered with precision to each zone.

The Fountain Valley-based company’s focus and goal from the start was to provide the highest quality of technical expertise and support, as well as exceptional customer satisfaction and service. Phoenix Controls was the first product line that ZES distributed, but soon after ZES added a full suite of critical space solutions including Aircuity and MK Plastic.
