Mechanical Acceptance Testing

Our certified HERS Raters are experienced and equipped to handle any Mechanical Acceptance Testing or Verification in San Diego and Riverside County.

No matter if you’re the owner of a mom and pop shop looking to remodel your business, or a large construction company with multiple projects, Grizzly HERS Testing is your solution to commercial Mechanical Acceptance Testing and Verification. Our certified technicians have almost 10 years of experience, and we are a California certified HERS Rater. We’ve built our reputation in San Diego and Riverside County by providing accurate and prompt verifications. We go above and beyond to provide a positive experience for our commercial clients.

Mechanical Acceptance testing specifies targeted inspections and functional performance tests.  These tests determine if the equipment installed in nonresidential buildings is operating as designed and in compliance with the Energy Code. These pass or fail tests are required for mechanical systems installed in newly constructed buildings, major renovations and for all new replacement equipment.

Our Commercial HERS Testing Certifications

Our approach is to provide permanent energy solutions by using state of the art performance equipment such as:
  • The Energy Conservatory (TEC) Duct Blaster
  • DG 700 Manometer, and Exhaust Fan Flow Meter
  • Alnor Flow Capture Hood or Velocity Matrix with Micromanometer
  • Fieldpiece Thermometers and gages
  • Testo Vane Anemometer
On top of using state of the art testing equipment, Grizzly HERS Testing is also certified in the following:
  • Cheers - Alterations, New Construction, Commercial
  • National Comfort Institute (NCI) - Commercial Air Balancing
  • National Comfort Institute - Duct System Optimization
  • Environmental Protection Agency (EPA) - Refrigerant Handling Certification
Common Mechanical Acceptance Testing:
  • Outdoor Air Verification (NRCA-MCH-02)
  • Single Zone Unitary Commissioning Form (NRCA-MCH-03)
  • Duct Leakage Verification (NRCA-MCH-04)
  • Air Economizer Controls (NRCA-MCH-05)
  • Demand Control Ventilation Systems (NRCA-MCH-06)
  • Fault Detection and Diagnostics for Package Units (NRCA-MCH-12)

Commercial Field Verifications

The below field verifications vary from job to job-based on the type of equipment installed. We perform the test best suited for your building

We perform the tests best suited for your home
Variable Air Volume System: This detailed test confirms the allocation of satisfactory open-air ventilation through the variable air management system at two operating conditions. The test consists of verifying outside air values at the minimum flow and also at peak flow. Per the California energy code, the test validates the introduction of a minimum amount of outdoor air into the air handling component. It must be inside the margin of 10 percent. This is the required air volume when the system is in occupied mode within these two conditions of supplied airflow.

This test validates the mechanisms of a constant volume, single‐zone, unitary air-conditioner, and heating pump system. The examination confirms all components, including thermostat installation and programming, supply fan, heating, cooling, and damper operation function correctly.

Testing the functionality of an air economizer cycle verifies the use of outdoor air to satisfy space-cooling loads in an HVAC system. The two types of economizer controls are stand-alone packages and Direct Digital Control (DDC). The stand-alone packages are commonly associated with small unitary rooftop HVAC equipment. DDC systems provide more precise control over HVAC, allowing you to set different temperature zones, schedule and automate system operation, and monitor performance over time.
This verification ensures a proper Fault Detection is in place and actively reports fault detection and diagnostics usually found in packaged DX units. The purpose of these FDD systems is to ensure the equipment is running optimally by constantly checking temperature sensors, airflow levels, and economizer operation. FDD systems truly help Maintain equipment efficiency at rated conditions throughout the lifetime of the equipment.
Variable Air Volume System: This detailed test confirms the allocation of satisfactory open-air ventilation through the variable air management system at two operating conditions. The test consists of verifying outside air values at the minimum flow and also at peak flow. Per the California energy code, the test validates the introduction of a minimum amount of outdoor air into the air handling component. It must be inside the margin of 10 percent. This is the required air volume when the system is in occupied mode within these two conditions of supplied airflow.
When a C02 sensor is required to be installed, this acceptance test is performed. Usually, a C02 sensor is mandatory when: A high-density space up to 40ft2 per person, the system has an outside air economizer / modulating outside air control, or system has Outside Air >3,000 CFM. The purpose of the examination is to verify that systems required to employ demand-controlled ventilation that can vary outside ventilation flow rates. This is based on maintaining interior carbon dioxide (CO2) concentration setpoints. Demand Controlled ventilation refers to an HVAC system’s ability to reduce outdoor air ventilation flow below design values when the space served is at less than design occupancy. CO2 is a good indicator of occupancy load and is the basis used for modulating ventilation flow rates.
