  • Performing phased tenant improvement build-outs coordinated around active production schedules and security protocols.
  • Commissioning integrated mechanical systems to verify airflow performance, controls functionality, and load capacity prior to turnover.
  • Implementing structured preventative maintenance programs to sustain long-term equipment performance and reduce unplanned downtime.
Representative Project Experience

L3Harris Technologies
Completed a comprehensive mechanical and facilities upgrade within an active, secure environment. Delivered a fully commissioned system meeting performance and reliability requirements, and retained to provide ongoing preventative maintenance and operational support.

Anduril Industries
Provided mechanical upgrades and system optimization to support facility expansion, and increased production and R&D demands across Southern California operations.

Airborne Systems
Long-term partner supporting tenant improvement build-outs and continuous mechanical maintenance for advanced defense manufacturing environments.

Business Outcomes

Operational Continuity – Mechanical upgrades executed within occupied, security-sensitive facilities without disruption to production or mission-
critical activities.

Performance Stability – Systems commissioned and maintained to support consistent environmental control in high-demand operational settings.

Scalable Capacity – Infrastructure enhancements aligned with facility expansion and increased operational load requirements.

Lifecycle Support – Ongoing maintenance relationships that extend system reliability beyond initial project delivery.

Why Contemporary Heating & Air Conditioning

Defense and aerospace facilities require a mechanical contractor that understands both technical complexity and operational sensitivity. Contemporary’s differentiators include:

  • Proven experience in secure, mission-critical environments
  • Ability to deliver both project execution and ongoing operational support
  • Deep expertise in regulated facilities where performance and compliance are non-negotiable
  • Long-standing client relationships built on trust, reliability, and execution

Rather than treating defense work as transactional, Contemporary approaches each engagement as a long-term partnership focused on performance and readiness.
