There is probably nothing more important to a great Heating and Air Conditioning system then starting with the proper design.
This starts by calculating the exact amount of Heating or Cooling needed into the home, as well as into each of the individual rooms. After these “Load Calculations” are done the system can be designed.
Next, determine the best location for the Heating and Cooling equipment. This could be the attic, crawlspace, basement, rooftop, etc. We take into consideration both the function of the system as well as the visual elements of trying to conceal the equipment as much as possible.
Supply Outlet and Return Inlet locations are selected (Grilles & register locations), based on proper circulation in a specific room. Other considerations are to eliminate drafts, or actually feeling airflow blowing, low sound levels, and of course putting the grilles in a visually appealing location.
The duct system can then be sized and designed based on the length of the ducts, the locations of the grilles, the location of the equipment, the layout of the room, large glass areas, and the general orientation of each room served by the system. Special consideration must be given to the sound the system produces when operating, with low sound levels maintained throughout the system.
Finally, a mechanical drawing/plan can be made. This typically shows all the items previously discussed in “plane view.” Grilles sizes, Grille locations, duct sizes, duct locations, equipment locations etc. This allows for the homeowner to review the system design before work starts, to have a better understanding of what is actually being installed in their home. This extra time devoted to designing the system, really helps to eliminate the “surprise” that could occur during an installation; especially an installation without the proper design done ahead of time.
