Correct Air Engineering offers residential load calculation HVAC design services to HVACR contractors. A properly performed Manual J, D and S will ensure that a HVAC system is sized correctly for every room of a home. With today's technology and tighter building construction; the old "rules of thumb" are not only outdated, but also inadequate. Unfortunately, the Manual J design can be complex and time consuming.

All of our Manual J, D, S, & N load calculations are STAMPED by a State Licensed HVACR Master!
All of our load calculations are suitable and certified for obtaining a mechanical permit.

"Implementing a quality HVAC system design is the foundation for a professional installation and year round comfort. Understanding the concepts behind load calculations, equipment selection, duct design, and room distribution is essential to the design process." (ACCA).
That's where we come in. We use only ACCA approved software to perform every load calculation, then your calculation is reviewed by a State Licensed Master for accuracy.

MANUAL J
A properly performed Manual J heat load calculation should be completed on every installation and retrofit and is now code in most municipalities. The Manual J will detail each room and living space with the proper cooling and heating requirements. An over sized system will have shorter run times along with humidity problems while an under sized system will not have the capacity to cool the house, run longer and shorten the life span of the equipment. Both situations will result in costing your client extra money. An ACCA certified Manual J load calculation will ensure that the air conditioner is sized properly for a home.

MANUAL S
The Manual S is used for equipment selection. The equipment selection process uses procedures to properly select the heating, air conditioning and heat pump equipment. This process looks at both the sensible and latent loads of the structure found in the Manual J calculation and compares it to the performance ratings of the equipment. Equipment size should not exceed 115% of the total heat load and should satisfy both the sensible and latent heat requirements. The Manual S will impact both the total CFM of the system and the size of the duct work required. Because of this, equipment selection will need to be made prior to completing the Manual D duct design. When providing a Manual S, we will need to know what brand equipment you prefer.

MANUAL D
Manual D is the proper sizing of the duct system. Once the Manual J room details and Manual S equipment sizing have been completed, we can begin to design the duct system for your project. If the duct system is not properly sized, the air conditioning system will most likely not perform as well as it should, have rooms that are too hot or to cold, excessive wear and tear on the HVAC system while costing more to operate. It is important to have the equipment selection made prior to performing the Manual D calculations because each manufacturer's equipment is different, which can impact the supply and return duct work sizes.

BLOCK LOAD
A block load looks at the entire structure as a whole to size the HVAC equipment. This is the minimum that should be performed when replacing a heating and air conditioning system. A block load calculation does not have a room by room breakdown, Manual S or D.
