Welcome, When the Building Department requires a Manual J (Heat Load Calculation), most clients and inspectors are unsure what to expect or how reports are read. Manual J has two calculations, a Block Load and Room x Room. Block Loads are calculated on the envelope of the building (whole house). A Room x Room has a higher accuracy,  provides the CFM per room and is easier to preform a duct design.

​

     Building department inspectors, need to be specific in their requests. Whenever in question of which Manual J, always refer back to the building department. Please note, every department is different in their requests, every inspector is different and open to interpretation. Through all the confusion, our utmost desire is to help you understand and assure Peace of Mind.    

     Please note, Manual D must accompany a Room x Room calculation. Manual D can be calculated alone, however, the design CFM must be submitted. To know what the cost will be, click on the Design Price Matrix and choose the service(s) you require.
