We’re looking for experienced Master Lead Commercial HVAC Service Technicians to support customers throughout the DC/MD market.

If you’re the type of technician who enjoys solving problems, takes ownership of your accounts, and would rather diagnose the issue than swap parts and move on, you’ll fit right in. Our team serves a diverse portfolio of commercial facilities including schools, healthcare facilities, laboratories, data centers, government buildings, refrigeration warehouses and Class A office properties.

You’ll work on a wide range of commercial HVAC and mechanical systems, build long-term customer relationships, mentor developing technicians, and join a team that values technical expertise, safety, and professional growth.

What You’ll Do

• Lead troubleshooting efforts on challenging service calls and serve as a technical resource for fellow technicians.

• Manage preventative maintenance and service activities across an assigned portfolio of customer accounts.

• Mentor and support junior technicians in the field, helping develop their technical and troubleshooting skills.

• Create clear, professional service reports and communicate findings and recommendations to customers.

• Identify repair, retrofit, and replacement opportunities and provide solution recommendations that deliver value to customers.

What We’re Looking For

• 8+ years of commercial HVAC service experience with in-depth knowledge of rooftop units, VRF systems, hydronic and steam boilers, pumps and towers, VFDs and building-automation integration and experience starting up and commissioning replacement equipment.

• Maryland Master HVAC

• Proven experience mentoring, training, and developing HVAC technicians in the field.

• Ability to scope, estimate, and help execute commercial HVAC repair, replacement, and retrofit projects.

• Advanced experience with major OEM equipment platforms and manufacturer training from Trane, Carrier, York/JCI, Daikin, or similar.

• EPA Universal Certification.

• Valid driver’s license and acceptable driving record.

• Willingness to participate in an on-call rotation (only once every 6-8 weeks!)

• Professional communication skills, both in the field and in written service documentation

Bonus Points For

• Critical-environment and healthcare experience; BAS programming on one platform; the path and the appetite to become a service manager or operations manager.

• Experience with building automation systems such as Niagara, Metasys, Tracer, or Desigo.

• Critical-environment experience supporting healthcare facilities, data centers, laboratories, or other mission-critical operations.

• OEM training from Trane, Carrier, York/JCI, Daikin, or similar manufacturers.

• NATE, A2L, or other industry certifications.

• Bilingual in English and Spanish.

• Interest in future leadership opportunities such as Service Supervisor, Service Manager, or Operations Manager.

• Chiller experience

What You Get

• Earn $52-$60/hour , with pay based on your experience, technical expertise, and license level.
• Take home a company vehicle, fuel card, phone, and everything you need to do your job successfully.
• Access consistent overtime opportunities and additional compensation through our on-call rotation.
• Continue growing your skills through company-paid OEM training, building automation exposure, and A2L refrigerant certification.
• Advance your career with company-paid Journeyman and Master HVAC licensing support.
• Enjoy a comprehensive benefits package, including medical, dental, vision, 401(k) with company match, paid time off, and paid holidays.
• Build a long-term career with a team that values technical expertise, rewards initiative, and promotes from within.
• The stability and resources of a publicly traded parent company with the culture and relationships of a locally operated service team that has served this market for nearly 55 years.
