Why Proper HVAC Duct & System Design Matters

In a state like Florida where unforgiving heat and humidity is the reality for much of the year, anything less than proper HVAC duct and system design does a disservice to your clients. Of course, you don’t intend to install a subpar HVAC system in any commercial or residential building. It’s just something that can happen when your HVAC load and energy calculations aren’t quite right and the equipment you select can’t meet the building’s actual demands. It’s also entirely preventable, though, and going the extra mile to ensure your calculations are flawless will help you avoid numerous project pitfalls.

What Can Go Wrong With Improper HVAC Duct & System Design?

Because every building’s design, purpose, and typical occupancy are different, there is no single solution that works for all buildings. Every HVAC duct and system design is the result of calculation and informed planning. If your load and energy calculations are off, and the equipment you select isn’t capable of providing proper air flow, many things can go wrong within a commercial or residential building, and they can affect both you and your clients:

  • Air leakage from ducts
  • Fluctuating temperatures
  • High energy costs and low energy efficiency
  • Hot and cold spots within rooms
  • Inadequate insulation
  • Increased air resistance
  • Loud, consistent noises during operation
  • Permitting issues and delayed project timelines
  • Poor indoor air quality
  • Reduced lifespans for HVAC systems
