Manual J, D and S are standards and protocols for proper design and installation of HVAC equipment and duct work. They model a building for energy efficiently by calculating equipment, duct sizing and system load calculations. These standards are part of the residential IECC and the Mechanical code.

CST testing ensures open combustion appliances (gas water heaters, gas stoves, and gas furnaces) are not causing unhealthy or hazardous conditions in residential or commercial buildings.

An air balance measures the performance of a commercial or residential HVAC system and adjusts to provide the occupants a comfortably conditioned space.

The REScheck assists builders, designers, and contractors in determining whether new homes, additions, and alterations meet the requirements of the IECC or state energy codes.

Leakage from ducts can account for up to 20% of the energy losses in a residential or commercial building. Duct leakage tests can determine the amount and location the leakage is occurring.​

Infrared imaging creates pictures showing the temperatures of surfaces. It is used in diagnosing temperature issues in a building’s energy performance.
