What Is Manual J? 

At Heat Load USA we provide a variety of services to home owners, and contractors. This web site is dedicated to providing you the information you need on our ACCA Manual J services.

Manual J is the calculation done to derive the amount of heating and cooling requirements on a home at the design summer and winter temperatures.  That is how many BTUs of heating, and BTUs of cooling do we need to maintain a certain temperature. From that, we can go to a Manual S calculation to select equipment. 

Contact us now for your Manual J whole-house report needs. We specialize in new construction and we can usually have your report to you in three-business days. 

Overnight & same-day hour rush service is available.
