This is a senior, hands-on service position for a technician with 10 years of experience who can contribute immediately without constant supervision.

Most work is performed in multifamily buildings, high-rises, offices, retail properties, schools, and hospitals throughout New York City. This is not an apprentice, maintenance-only, or installation-only position.

What You’ll Do:

• Diagnose, service, maintain, and repair commercial HVAC and boiler systems.
• Work on Scotch Marine and firebox boilers, generally within the 100–600 size range.

• Service rooftop units, packaged units, split systems, mini-splits, and VRF systems.
• Diagnose heating and boiler controls, including Heat-Timer systems.
• Perform seasonal preventive maintenance and detailed equipment inspections.
• Work with steam coils, control valves, and related heating components.
• Read wiring diagrams and diagnose mechanical, electrical, and control-related failures.
• Identify the underlying cause of equipment failures and complete lasting repairs.
• Communicate findings and repair recommendations to dispatch, management, customers, and building personnel.
• Contact manufacturer technical support when necessary and follow problems through to resolution.
• Complete accurate service documentation using company-provided technology.
• Maintain a clean, safe, stocked, and professional company vehicle.
• Participate in manufacturer-specific technical training and continuing education.

Key Requirements:

• Experience: 10 years of commercial HVAC and boiler service experience strongly preferred; five years of directly relevant experience is the absolute minimum.
• Boiler Skills: Proven ability to independently diagnose and repair commercial boilers, burners, pumps, controls, safeties, steam coils, and control valves.
• HVAC Skills: Strong experience troubleshooting rooftop units, packaged units, split systems, mini-splits, and VRF systems.

• Safety Credentials: Applicable OSHA training and NYC FDNY Certificates of Fitness required.
• Troubleshooting: Ability to read schematics and independently diagnose mechanical, electrical, refrigeration-cycle, and control-related failures.
• Customer Service: Ability to communicate professionally with customers, residents, building personnel, dispatchers, and supervisors.
• On-Call: Willingness to participate in the mandatory on-call rotation and work additional hours during peak seasons.
• License: Valid driver’s license with a clean driving record.
• Professionalism: Must be dependable, conscientious, team-oriented, receptive to feedback, and capable of working in occupied buildings.

Preferred (Not Required):

• 10–20 years of commercial HVAC and boiler service experience.
• Experience with Scotch Marine and firebox boilers.
• Experience with Heat-Timer boiler controls.
• Experience servicing multifamily buildings, high-rises, hospitals, schools, offices, and retail properties.
