The Opportunity

We’re seeking experienced Senior Commercial HVAC Service Technicians to support customers throughout the DC/MD market.

  • 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.
  • undefined

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.
  • 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.
