When you pull a permit for a remodel, new addition, or new construction project—and you’re installing or altering a heating, air conditioning, or duct system—Energy Code Compliance (ECC) testing is required. A preliminary Compliance Certificate is typically generated at the start of the project, and that document outlines the specific tests needed for final sign‑off.
At CalRATERS Energy Solutions, we’re here to make this part of your project simple, fast, and predictable. We know exactly what steps to take to keep your job moving so you can complete your project and close out your permit without delays.

Once testing is complete, our office team prepares your final paperwork and delivers it to your inbox within a day or two—often sooner—so you can call in your final inspection as quickly as needed.
When you’re ready to wrap up your project, we’re ready to help you get it across the finish line.

Duct leakage testing is an ECC measure that is required in all climate zones with any new furnace, air conditioner and/or ductwork installation.
The purpose of total duct leakage testing is to effectively measure how much air is leaking from your duct system into areas you don’t want it heating or cooling and to verify that the ductwork has been properly sealed to California standards.

Airflow testing is an ECC measure that is required in most climate zones when a new air conditioner and/or new ductwork is installed.
The purpose of an airflow test is to verify that the proper amount of airflow is going to the cooling unit. If proper airflow is not going to the cooling coils, ice build could up will occur in the coils which can lead to compressor failure.

Refrigerant charge testing is an ECC measure that is required in most climate zones when a new air conditioner is installed.
The purpose of refrigerant charge verification is to determine whether or not the cooling system has the correct amount of refrigerant “charge” needed to properly cool your home based on the factory specifications for that particular air conditioner and climate zone. This will ensure that your air conditioner is cooling properly on those hot summer days.

Quality Insulation Inspection (QII) is an inspection that ensures the insulation in your home is installed to a particular standard set by the California Energy Commission.
If your energy compliance documentation includes a requirement for a QII, it is imperative to contact us at the beginning of your project so that we can perform the inspection before walls and sheetrock cover up you insulation.

Indoor Air Quality (IAQ) Mechanical Ventilation testing is intended to improve the indoor air quality in your home by testing for low infiltration and natural ventilation rates.
We will perform this test at your bathroom vents to make sure that you are achieving proper ventilation.

When a forced air unit (heater or air conditioner) turns on, a fan blows air through the duct system. This fan draws electricity (measured in watts).
Fan Watt Draw Testing measures how much electricity the fan uses at full power relative to how much air is being moved.

SEER (Seasonal Energy Efficiency Rating) is the rated efficiency of an air conditioner. A SEER Verification is performed by using a directory of heating and air conditioning equipment to verify that your air conditioner meets the required efficiency rating.

These are just some of the most common tests required in a new construction project. Additional tests include Whole House Fan Testing, Water Heater Verification, etc.
