Mechanical Acceptance Testing

RSES-certified California Title 24 mechanical acceptance testing for commercial and industrial facilities throughout Santa Clara County, Santa Cruz County, Alameda County, Contra Costa County, Monterey County, and San Francisco. Golden Gate Mechanical, Inc. — CSLB #646854.

California Title 24 mechanical acceptance testing is a required step for new commercial construction and major renovations throughout the state. Golden Gate Mechanical, Inc. holds an RSES Mechanical Acceptance Tester certification — issued by the Refrigeration Service Engineers Society, one of the most respected credentialing bodies in the mechanical industry. As a result, building owners, developers, and general contractors throughout the San Francisco Bay Area rely on us to provide the verified testing and documentation required for permit sign-off on their projects. Furthermore, because we are also the installing contractor on many of our projects, we bring a deeper understanding of the systems being tested than a third-party testing firm typically can.

What is mechanical acceptance testing?

California Title 24 Part 6 — the California Energy Code — requires that mechanical systems in new and renovated commercial buildings be tested and verified to confirm they operate as designed and meet state energy efficiency requirements. This testing must be performed by a certified acceptance tester and the results submitted to the local authority having jurisdiction as part of the permit close-out process. In addition, acceptance testing covers a wide range of mechanical systems including HVAC equipment, controls, economizers, demand controlled ventilation, and refrigeration systems. Without completed acceptance testing, a certificate of occupancy cannot be issued for the building.

Our acceptance testing process

Project review

We review construction documents, equipment submittals, and Title 24 energy compliance forms before field work begins

Field verification

Our RSES-certified tester performs all required field tests and measurements per California Title 24 acceptance test procedures

Documentation

We complete all required California Energy Commission acceptance test forms and provide copies to the owner, contractor, and authority having jurisdiction

Permit sign-off

Completed acceptance test documentation is submitted for permit close-out, enabling the building to receive its certificate of occupancy

Acceptance testing we perform

HVAC systems

Acceptance testing of rooftop units, split systems, package units, air handlers, and all other commercial HVAC equipment per California Title 24 requirements. We verify equipment performance, airflow, and controls operation against design specifications.

Economizers

Testing and verification of air and water economizer systems to confirm proper operation, controls sequencing, and compliance with Title 24 economizer requirements. Economizer acceptance testing is one of the most commonly failed tests — our experience as an installing contractor helps us identify and resolve issues quickly.

Demand controlled ventilation

Verification of demand controlled ventilation systems including CO2 sensor calibration, controls sequencing, and minimum ventilation rate confirmation per Title 24 requirements. Furthermore, we verify that DCV systems respond correctly to occupancy changes throughout the building.

System controls

Testing and verification of HVAC controls systems including thermostats, building automation systems, setback controls, and supply air temperature reset sequences. As a result, building owners can be confident their systems are controlling correctly and not wasting energy through improper controls operation.

VRF systems

Acceptance testing of Variable Refrigerant Flow systems per California Title 24 requirements. As factory-certified Daikin, Mitsubishi Electric, and LG installers, we bring deep system knowledge to the acceptance testing process for VRF equipment.

Refrigeration systems

Title 24 acceptance testing for commercial refrigeration systems including walk-in coolers, freezers, and display cases. We verify system performance, controls operation, and energy efficiency compliance per California Energy Code requirements.

Who needs mechanical acceptance testing?

New commercial construction — all new commercial buildings in California require Title 24 mechanical acceptance testing before a certificate of occupancy can be issued
Major renovations — significant HVAC replacements and renovations in existing commercial buildings trigger acceptance testing requirements
Tenant improvements — tenant improvement projects that include new or modified HVAC systems typically require acceptance testing
General contractors — GCs on commercial projects need a certified acceptance tester to close out mechanical permits
Building owners and developers — acceptance testing is required before occupancy and is a condition of most construction loans and lease agreements
