The hidden network of ducts in your home is the circulatory system of your HVAC setup. Without properly designed and installed ductwork, even the most expensive air conditioner or heat pump will fail to keep you comfortable. At Priority One Heating & Air, we specialize in high-quality ductwork installation in Eugene and the surrounding areas. Whether you are building a new home, adding a central air system to an older property, or replacing compromised ducts, our team ensures your system delivers balanced, efficient airflow to every room.

When Is New Ductwork Needed?

Many homeowners in Eugene don’t think about their air ducts until there is a problem. However, there are several scenarios where installing new ductwork in Eugene is not just an option but a necessity for comfort and efficiency.

Adding AC to Older Homes

Many of Eugene’s charming historic homes were built before central air conditioning became standard. These homes often rely on radiant heat or gravity furnaces and lack the necessary infrastructure for modern cooling. Installing a central AC or heat pump system often requires a complete retrofit, designing a new duct system that fits within the existing architecture without ruining the home’s aesthetic character.

New Construction Projects

Building a new home offers the perfect opportunity to get the HVAC system right from the start. We work with builders and homeowners to design HVAC ductwork in Eugene that is perfectly sized for the layout of the house, ensuring optimal efficiency and comfort from day one.

Home Additions and Remodels

If you are expanding your living space, your existing duct system may not be able to handle the increased load. Extending the current ducts without proper load calculation can lead to weak airflow and hot spots. In many cases, a dedicated zone or a reconfigured duct system is required to serve the new addition effectively.

Replacing Old, Damaged Ducts

Ductwork doesn’t last forever. Over the decades, ducts can rust, collapse, or become infested with pests. If your current system is leaky, poorly insulated, or improperly sized, replacing it can significantly lower your energy bills and improve indoor air quality. If you aren’t sure if you need a full replacement or just repairs, check our duct repair services for more information.

Our Ductwork Installation Process

Great ductwork starts with great design. We don’t just hang pipes; we engineer a solution tailored to your home.

  1. Manual D and Manual J Calculations: We start by calculating the heating and cooling load of your home (Manual J) and then designing the duct system (Manual D) to deliver the precise amount of air required for each room.
  2. Material Selection: Based on the design, we select the appropriate materials to ensure durability and airflow efficiency.
  3. Installation: Our skilled technicians install the ductwork, securing it firmly to minimize vibration and noise.
  4. Sealing and Insulating: We meticulously seal joints and seams to prevent air leakage, which is a major source of energy loss. In unconditioned spaces like attics or crawlspaces, we ensure ducts are heavily insulated.
  5. Testing: Once installed, we test the system for static pressure and airflow to verify that it performs exactly as designed.

Types of Duct Materials We Use

We utilize a variety of materials depending on the specific needs of the installation:

  • Sheet Metal: The most durable and widely used material. Its smooth surface offers excellent airflow and is resistant to mold growth.
  • Flexible Ductwork: Ideal for tight spaces and connecting main trunks to vents. We use high-quality flex duct to minimize sagging and restriction.
  • Fiberboard: often used for main trunk lines, offering built-in insulation and sound-dampening qualities.

The Importance of Proper Sizing for Airflow

The most common issue with duct installation in Eugene, OR, is improper sizing. Ducts that are too small restrict airflow, forcing your HVAC equipment to work harder and shortening its lifespan. Ducts that are too large can lead to a drop in velocity, meaning air doesn’t reach the vents with enough force to circulate properly.

Our team focuses heavily on aerodynamics. We ensure return air ducts are large enough to feed the system and supply ducts are balanced to maintain even pressure throughout the house.

Considerations for Eugene Homes

Eugene has a diverse mix of housing stock, from mid-century moderns in the hills to Craftsman bungalows near downtown. Each presents unique challenges for ductwork installation.

  • Older Homes: We often navigate tight attics, crawlspaces, and closets to retrofit ducts.
  • Retrofits: We specialize in finding creative routes for ductwork to minimize the impact on your living space, sometimes utilizing closets or creating soffits that blend into the room.
  • Energy Efficiency: With Oregon’s focus on green energy, we prioritize sealing and insulation to meet or exceed local codes.

Cost Factors for Ductwork Installation

The cost of installing ductwork varies widely based on several factors:

  • Size of the Home: Larger homes require more materials and labor.
  • Accessibility: Working in a spacious, unfinished basement is cheaper than navigating a cramped, spider-filled crawlspace.
  • Zoning: Systems with multiple zones (thermostats for different areas) require more complex damper systems and design work.
  • Materials: Rigid sheet metal generally costs more than flexible ductwork but offers superior longevity.

Custom Sheet Metal Fabrication

Unlike many contractors who rely solely on pre-fabricated parts, Priority One Heating & Air Conditioning can fabricate custom sheet metal ductwork. This means we aren’t limited to “off-the-shelf” solutions. If your home has a unique angle or requires a specific transition piece for maximum airflow, we build it ourselves. This ensures a tighter fit, better appearance, and superior performance.
