Commissioning plays a pivotal role in the successful implementation and operation of various commercial, industrial, and pharmaceutical facilities. APEC Mechanical is a provider of comprehensive commissioning services in Southern California specializing in ensuring that systems and equipment perform optimally and meet the desired standards. Our expertise in commissioning spans across a wide range of industries, and our services are designed to enhance functionality, efficiency, and overall performance.

Thorough Planning and Preparation:

APEC Mechanical approaches commissioning with meticulous planning and preparation. Our team collaborates closely with clients to understand their project goals, requirements, and expectations. We develop a customized commissioning plan that outlines the scope of work, schedules, and key performance indicators. By thoroughly evaluating the project’s unique needs, we tailor our approach to deliver the most effective commissioning services.

Systematic Testing and Verification:

Our skilled commissioning team conducts systematic testing and verification of various systems and components within the facility. This includes HVAC systems, electrical systems, plumbing, fire protection systems, control systems, and more. Through comprehensive testing protocols, we ensure that all systems are installed correctly, calibrated accurately, and operate in accordance with the design intent. Any deviations or performance issues are identified, allowing for timely adjustments and improvements.

Functional Performance Verification:

APEC Mechanical places great emphasis on functional performance verification during the commissioning process. We go beyond simple functionality checks and evaluate the performance of systems under various operating conditions. By conducting performance tests, we assess factors such as energy efficiency, temperature control, airflow, and overall system integration. Our aim is to ensure that the systems not only function as intended but also deliver optimal performance for the facility’s specific needs.

Compliance and Documentation:

Compliance with regulations and industry standards is a crucial aspect of commissioning. APEC Mechanical meticulously checks and verifies compliance with relevant codes, standards, and project specifications. We provide comprehensive documentation that includes detailed reports, test results, and certification to validate the successful commissioning of the facility. This documentation serves as a valuable resource for ongoing maintenance, audits, and future upgrades.

Ongoing Support and Optimization:

APEC Mechanical believes in long-term partnerships with our clients. After the initial commissioning process, we offer ongoing support and optimization services. We provide recommendations for system enhancements, energy efficiency improvements, and maintenance strategies to ensure continued optimal performance. Our team is always available to address any concerns, troubleshoot issues, and provide guidance to maximize the facility’s operational efficiency.


APEC Mechanical’s commissioning services are a vital component of successful facility implementation and operation. With our thorough planning, systematic testing, functional performance verification, compliance checks, and ongoing support, we ensure that your facility performs at its best. Contact us today to benefit from our expertise and ensure the optimal performance of your facility.

The commissioning process is outlined in our Commissioning Brochure.

Whole Building Commissioning

In short, anything affecting the building performance, occupant comfort, or user services within a building are part of Whole Building Commissioning


  • Occupant satisfaction and safety
  • Cost Savings Energy, operation, equipment maintenance and equipment replacement
  • Smoother Construction Process, quicker final acceptance and reduced warranty call-backs


  • Reduction of change orders and additional claims
  • Fewer deficiencies at substantial completion
  • Fewer Project delays
  • Managed start-up procedures
  • Shorter building turnover transition period
  • Improved indoor air quality and occupant productivity
  • Better operation, maintenance and reliability
  • Lower energy and operational cost
  • Complete and useful documentation
  • More Knowledge to O&M staff

Retro Commissioning and Re-Commissioning of Existing Buildings

Retro-Commissioning is a process to improve the operating performance, energy consumption, energy efficiency, operation & maintenance procedures of existing building’s equipment and systems.
APEC Mechanical will conduct a comprehensive audit to ensure the building systems (hydraulic, mechanical/HVAC, electrical, fire, and control systems) are operational as originally planned and constructed. Tests are performed to identify if system operation, design, or mechanical/electrical/control have compromised the performance of building services.


  • Optimize facilities equipment performance and ensure optimum system operating points.
  • Verification of control system and calibration and adjustment of equipment
  • Ensure that minimum energy consumption at system operating point and increase performance
  • improve indoor air quality


  • Ensure design and performance conditions
  • Improve indoor air quality
  • Increase energy efficiency and reduce energy costs
  • Reduce operation and maintenance costs
  • Increase equipment life
  • Reduce occupancy complaints and increase tenant satisfaction

Commissioning for LEED Certification & Sustainability

We provide an integrated approach that will assist in achieving your sustainability-related goals.

  • LEED: We streamline the certification process by managing projects from conception through certification to identify, evaluate, and document all LEED point requirements.
  • CALGreen: APEC Mechanical complies to the guidelines and scope set out in the new California Energy Code, referred to as CALGreen, which requires commissioning of new non-residential building construction.
  • Energy Star: APEC Mechanical can assist building owners in attaining the EPA Energy Star Certification by verifying that planned energy performance goals are met operationally.

Peer Review

APEC Mechanical represents the client’s best interests by working collaboratively alongside the design and construction teams to ensure that established objectives for long-term durability, serviceability, and performance are maintained throughout the Schematic Design, Design Development, and Construction Document phases of the design process. During the Pre-Construction and Construction phases of the project, APEC Mechanical will continue to work closely with the design and construction teams to further develop and refine the design.

Building Systems Optimization

APEC Mechanical has the design experience and operational experience to review the operations of your systems (control sequences, TAB reports, design drawings, etc.) and recognize inconsistencies, problem areas and identify energy saving opportunities.

Energy Audits – ASHRAE Level 1, 2 and 3

An Energy Audit is an inspection, survey, and analysis of energy flows for energy conservation in a building, process, or system to reduce the amount of energy input. APEC Mechanical provides ASHRAE’s 3 Level Energy Auditing Process:

Level 1: Walk-Through Survey
Level 2: Energy Survey & Analysis
Level 3: Detailed Analysis of Capital Intensive Modifications
