Frequently Asked Questions About HVAC Design

What is the Manual J Calculation?

Manual J is the part of the Air Conditioning Contractors of America (ACCA) protocol that calculates the amount of heating and cooling each area of your home needs. Once we have the Manual J calculation, we can pick the right equipment for your HVAC system. 

Do You Need Manual S to Pick HVAC Equipment?

Yes, Manual S, and the process that leads up to it, is incredibly important to the ACCA protocol. Instead of randomly selecting the equipment for your HVAC system, taking the calculations for Manual J and following Manual S to get exact manufacturer specifications prevents issues down the line in your HVAC installation. 

How Does Manual D in HVAC Design Work?

Manual D is the last step of the protocol where the design of ductwork comes into play. Manual D is the layout and sizing of the actual HVAC ductwork system, taking the calculation from Manual J and the equipment selection from Manual S into account. When Manual D is handled correctly by a true HVAC pro, you will get the best, cleanest airflow possible.
