When a load calculation is done for a residential property it is known as a Manual J.  When it is done for a commercial property - like a church or office, it is known as a Manual N and we need more information from you, for a commercial load calculation.  

We provide Manual N services for clients all over the US. Most of our customers are architects, engineers, contractors and business owners. 

Our reports are ACCA Manual N compliant and that means they are accepted nationwide for sizing of your heating and cooling needs of a business.  

Information like how many occupants by hour and by day? What machines, stoves, refrigerators, freezers, cooking appliances, motors, computers, printers and ...... lighting in the building.  Often the owner many not know, and we then have to take an educated guess.
