• 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
• Maryland Master HVAC - or has held a Journeyman license for at least 3 years and is eligible to sit for the master exam. We will pay for the exam.
• Proven experience troubleshooting advanced commercial HVAC systems, including boilers, pumps, cooling towers, VFDs, and building automation interfaces.
• Experience commissioning equipment, performing startups, and supporting replacement projects in the field.
• Demonstrated ability to mentor and develop less experienced technicians.
• 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 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.
• Experience scoping and estimating repair, retrofit, and replacement projects.
• 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.

What You Get

• Earn $44-$52/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.
