Custom Ventilation

The Hidden Key to HVAC Efficiency: Custom Ventilation

When you think about your heating and cooling, you probably think about your furnace or your air conditioner. But the most important part of your entire comfort system is the one you never see: your HVAC ductwork.

It’s the highway that carries your conditioned air, and if that highway is leaky, poorly designed, or the wrong size, your whole system suffers. In fact, leaky or inefficient ductwork can waste up to 30% of your conditioned air, leading to sky-high energy bills, frustrating hot and cold spots, and poor indoor air quality.

At R.D. Davis Heating and Air Conditioning, we have the solution. We are one of the few  HVAC contractors in the Springfield area with our own in-house, state-of-the-art sheet metal shop. We don’t rely on off-the-shelf, one-size-fits-all parts. We design and build perfect, high-efficiency custom ventilation systems from scratch, ensuring your system runs at peak performance.

Why We Use Galvanized Steel for All Custom Ductwork

We don’t compromise on materials. We fabricate all of our duct systems from high-quality, American-made galvanized steel.

Galvanized steel is a dense steel sheet that has been coated in a layer of zinc, making it exceptionally strong and rust-proof. While other contractors may take shortcuts with flexible ductwork, we choose galvanized steel for its clear, long-term advantages.

  • Unmatched Durability: Galvanized steel is built to last. Unlike flexible ducts that can be easily torn, crushed, or punctured, a professionally installed steel system can last for 25 to 50 years.
  • Superior Airflow: The smooth, non-porous interior of steel ductwork allows air to move with far less friction and resistance. This efficiency means your system doesn’t have to work as hard, saving you money.
  • Better Air Quality: That same smooth surface is resistant to mold and fungus growth. It doesn’t trap dust, dander, and other contaminants the way flexible ducts do.
  • Corrosion Resistant: The zinc coating protects the metal from moisture, making it the perfect solution for basements, crawlspaces, or even outdoor applications.

The Benefits of a Custom-Fabricated Duct System

A custom-fit system built by a professional custom ductwork contractor is an investment that pays you back for decades. When your ductwork is designed specifically for your property, you’ll feel the difference immediately.

  • A Perfect, Precision Fit: We design the system for your home’s unique layout, ensuring no “close enough” gaps or inefficient, sharp turns. This precision minimizes energy loss from day one.
  • Maximum Energy Efficiency: An airtight, custom-sealed system means every single dollar you spend on heating and cooling gets to the right room. No leaks, no waste.
  • Drastically Improved Air Quality: Leaky, old, or flexible ducts can pull in dust, mold, insulation fibers, and contaminants from your basement, crawlspace, or attic. Our sealed metal system ensures the air you breathe is clean.
  • Consistent, Even Comfort: This is the most noticeable benefit. A custom-designed system eliminates those annoying hot and cold spots by delivering the right amount of air to each room.

Our Fabrication Process: From Design to Reality

Our galvanized ductwork fabrication process is an intricate blend of modern technology and old-school craftsmanship. We don’t just build ducts; we engineer a complete airflow system.

Design & Load Calculation: It all starts with the math. We perform a detailed load calculation to determine the exact airflow (CFM) needed for each room. We then use this to design the perfect duct system to support your furnace and AC.

Precision Fabrication: In our in-house Springfield sheet metal shop, our skilled fabricators get to work. Using precision shears and brakes, they cut and form the galvanized steel ductwork to the exact specifications of our design.

Professional Installation & Sealing: Our technicians install the new system. We use professional-grade duct mastic sealant and metal tape—not standard “duct tape”—to make every seam and joint 100% airtight.

Frequently Asked Custom Ductwork Questions

Is custom ductwork more expensive than standard options?
The initial upfront cost can be higher than for standard, off-the-shelf flexible ducts. However, the investment often pays for itself over time through significant energy savings, fewer repairs, and a system that lasts 25 years or more.
How can I determine the right size and shape for my ductwork?
Our certified professionals perform a detailed load calculation to determine the exact size (diameter or dimensions) and shape (round or rectangular) needed for each room. This isn't guesswork - it's building science.
Who should install custom ductwork?
This is a specialized skill. It should only be handled by a professional, certified sheet metal ductwork specialist, like the in-house team at R.D. Davis.
Do these ducts need to be sealed?
Yes, this is one of the most critical steps. Proper sealing at all seams and joints is what makes the system airtight. We use professional-grade duct mastic sealant and metal tape, which will never dry out or fail like standard cloth "duct tape."
