*Disclaimer

The following pages summarize the heat gain and heat loss of the building using the ACCA Manual J8 calculation procedure. The calculations are based on the information given to Manual J Express in the form of drawings, sketches, and interviews. In certain cases, Manual J Express may make assumptions about design conditions that may or may not be accurate for the location of concern. It is the responsibility of the installing HVAC contractor to verify the design conditions before equipment purchase and installation.

Any load calculations provided in the following pages are based upon information provided by the party submitting a particular project to Manual J Express. Manual J Express has not and does not independently verify that the data provided to Manual J Express is correct or complete, and any calculations made by Manual J Express are based upon the information provided by third parties. Manual J Express makes no claim that the information given to us is correct or complete.

Manual J Express utilizes WrightSoft Residential 12.0 which is an ACCA Certified and ASHRAE recommended computer program to determine the heating and cooling loads presented in this report and is therefore very accurate. If the information given to Manual J Express is accurate, and the building is built as per the plans submitted, then the load calculations presented in this report can be assumed to be accurate. A licensed mechanical contractor may use these calculations as a starting point in system sizing and selection.

Manual J Express does not provide architectural or engineering plans or diagrams for the public or for use by contractors or construction companies as final “construction documents”. Manual J Express works with architectural and engineering firms and with contractors in connection with their designs of heating and air conditioning systems.

If the HVAC duct layout installed on-site DOES NOT match the Manual D duct design prepared by Manual J Express, then Manual J Express cannot and will not guarantee the performance of any altered duct design.

Final HVAC sizing and selection should be done by a licensed HVAC contractor. Many factors beyond the scope of this report must be considered prior to final system selection and design, such as: exact equipment availability and selections, system controls and location of controls, system air distribution and cycling, Uniform Building Code requirements, Uniform Mechanical Code requirements, and many other standard design conventions as listed by the American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE).

Manual J Express therefore assumes no liability for final equipment selection or final system design. Various modifications to the information provided to Manual J Express may have occurred after this Design Support information was prepared, which would require that this Design Support information be modified in order to be accurate. After reviewing Manual J Express report, and prior to any system purchase or installation, please Manual J Express in writing of any changes which may alter the assumptions and calculations contained in this report.

Manual J Express delivers precise HVAC load calculations, duct sizing, and energy compliance solutions to ensure efficient, comfortable, and code-compliant homes.
