If you take a fan out into your yard on a calm day and turn it on, you’ll get its maximum air flow. If you take that same fan and blow the air into a cardboard tube, it has to work against the pressure that builds up in that space. The more you reduce the size of that tube or make it longer or turn the air with it, the more static pressure builds up. And the more the air flow is reduced. That’s the basic principle you have to work with in duct design.
Designing a duct system is important but there are a few critical steps that come first. Number one is the heating and cooling load calculation. You’ve got to know how much heating and cooling you need for each room (in BTU/hr). Then those BTU per hour requirements immediately translate to room-by-room air flow requirements in cubic feet per minute (cfm). At High Mark Heating & Cooling it’s done automatically in the software we use (RightSuite Universal by WrightSoft). Once you know the BTU/hr and cfm numbers for the building, you need to select the right equipment. There’s more to it than just finding a piece of equipment that meets the total heating and cooling loads for the home. You’ve got to make sure you adjust for the indoor and outdoor design conditions of the home and have the manufacturer’s performance data tables to get it right. Now we’re ready to start designing your duct system.
If you want your heating, cooling, and ventilating system(s) to perform well, you need to start with good design. Here's why:
• You’ll get a new heating and cooling system that is sized properly. Most new air conditioners are oversized, which means they don’t dehumidify as well and can break down sooner.
• You’ll get a distribution system that delivers the right amount of conditioned air to each room. Don’t skimp on this part of the HVAC system.
• Your home will be comfortable and efficient. High Mark Heating & Cooling will perform detailed calculations to ensure it.
