Our HVAC Design Service

A quality HVAC Design yields a home comfort solution far superior then one where the ducts are laid out simply using the sq. ft./ton methodology.  A true HVAC design takes into account the orientation of the home, the zip code, elevation, summer and winter temperatures, humidity levels and much more. 

No call backs  The goal of a quality HVAC design is total occupant comfort.  Comfort is driven by several factors including temperature, humidity, air velocity and noise.  Planned occupant comfort starts with a quality HVAC Design.

What is Manual J, Manual D and Manual S?



Manual Jis the heat load calculation for the whole house


Manual D is the layout and sizing of your all NEW duct-work. This is typically only required when you are installing new ductwork, as in an addition, new construction etc. We layout each individual room in the house and required CFM. You tell us where you want the ducts and registers OR we lay them out for you.


Manual S is the selection of equipment based on the heat load of the house.  ONCE we have figured out the total heat load (Manual J) on the house, we will provide you the full AHRI (furnace model, condenser and coil numbers based on which line you you are using or tell us what you want to use and we will do our best to make that match).


What if I Only Need Manual J & S?   No problem. We can do that too! Unless you are installing new ductwork, you only need a Manual J and occasionally, Manual S. 


Do You Provide Next Day Service? In most


Does Your Work Conform to ACCA Requirements? Absolutely! All the work we do confirms to ACCA, and we stand behind our heat load and duct sizing reports. We guarantee that it will pass your local building inspections. You provide us the necessary drawings of the home, and equipment you want to us.  Also,  some townships may require additional licensing/certifications that are outside our scope of work.
