Applications Specialist - Commercial HVAC

About the role

This role is focused on maximizing the application of CAREL's control and cooling solutions in commercial HVAC environments by developing, communicating, and implementing market best practices for medium-to-large equipment installations with OEMs, end-users. The Application Specialist guides OEM applications and commissioning for commercial HVAC equipment including Dedicated Outdoor Air Systems (DOAS), rooftop units (RTUs), commercial heat pumps, variable refrigerant flow (VRF) systems, and air handling units (AHUs), leveraging CAREL's full portfolio of controllers, drives, dampers, heat exchanger, valves, and supervisory solutions.

Responsibilities

• Actively supports design and implementation of complete CAREL HVAC control solutions with OEMs in commercial markets, focusing on energy efficiency, dehumidification performance, ventilation compliance (ASHRAE 62.1), demand-controlled ventilation, and integration with BMS/BAS platforms.
• Guides OEM selection and configuration of CAREL controller-electronic expansion valves, variable speed drives (CAREL inverters), and supervisory systems for DOAS, RTU, heat pump, and AHU applications.
• Supports commissioning, startup, and troubleshooting of commercial CAREL-controlled equipment at OEM facilities and customer job sites, with focus on refrigerant circuit optimization, economizer logic, heat recovery wheel controls, and humidity management.
• Provides technical expertise on integration of CAREL systems with building automation systems (BAS/BMS) via BACnet, Modbus, and LonWorks protocols in commercial building environments.
• Participates in product strategy and development discussions with CAREL's global engineering teams based on commercial application needs.
• Develops and delivers technical training programs, application notes, configuration guides, and commissioning documentation for OEM partners, mechanical engineers, and building contractors.
• Partners proactively with OEM engineering teams to help plan, design, and solve systemic control issues before units ship to commercial job sites.
• Collaborates with sales, engineering, marketing, and product management to develop commercial application solutions responsive to market needs.
• Communicates in a timely manner the status and actions needed for problem resolution internally and externally; elevates urgent issues related to commercial HVAC control failures or opportunities.
• Identifies best CAREL controller practices from the OEM and contractor perspective, developing application standards that address common commercial HVAC requirements.

Requirements

• Demonstrated ability to configure, commission, and troubleshoot medium-to-large commercial HVAC equipment including DOAS, RTUs, heat pumps, AHUs, and chillers.
• Specific hands-on experience with CAREL controller platforms, electronic expansion valves, and variable speed drives in commercial applications is strongly preferred.
• Skilled at gathering and analyzing system data from CAREL controllers.
• Works effectively across OEM engineering teams, mechanical contractors, building engineers, and internal CAREL sales and product teams.
• Balances individual technical responsibility with collaborative teamwork, contributing positively to cross-functional goals and customer outcomes.
• Provides accurate, clear, and timely technical information to OEM engineering contacts, specifying engineers, mechanical contractors, and building owners.
• Leverages internal CAREL resources and global expertise to drive positive commercial outcomes with urgency and professionalism.

Qualifications

• Bachelor's degree in Mechanical Engineering, Electrical Engineering, or a related technical field is preferred.
• Equivalent hands-on technical experience in commercial HVAC applications will be considered.
• Requires a Minimum Of Three Years Of Experience Configuring And Troubleshooting Commercial HVAC Control Systems, With Specific Documented Experience In Two Or More Of The Following:
• DOAS controls: energy recovery, dehumidification, hot gas reheat, DCV, and ASHRAE 62.1 compliance
• Commercial rooftop unit controls: compressor staging, economizers, variable speed fans, demand response
• Commercial heat pump systems: reversing cycle, defrost, EXV control, hydronic integration
• AHU controls: VAV, supply air reset, heat recovery, commercial humidification
