Air Duct Installation in Spokane

Custom Ductwork Built for Your Home, Backed by 80 Years of Local Experience

Whether you’re installing a central HVAC system for the first time or replacing ductwork that’s past its useful life, the quality of your duct system shapes how well your home heats and cools. Sturm has served Greater Spokane since 1945, and our approach starts with honest assessments and ends with work we’re proud to stand behind. We’re BBB A+ accredited and a NADCA member, and we bring the same commitment to quality workmanship to every installation project we take on.

We handle both new ductwork installations and full duct system replacements throughout Spokane County, designing and building to each home’s specific needs rather than making prefabricated stock work where it doesn’t fit.

Our In-House Sheet Metal Fabrication Shop

Sturm operates an in-house sheet metal fabrication shop that designs, fabricates, and installs custom HVAC ductwork from the ground up. We work with galvanized metal, hot roll steel, cold roll steel, and stainless steel, matching materials to what each project actually requires. That means the ductwork going into your home is built to your home’s exact dimensions and layout, not adapted from a standard shape that’s close but not quite right.

This capability matters most in homes with unique architectural features, limited installation space, or irregular configurations where off-the-shelf sections leave gaps and create airflow problems. Because fabrication and installation happen under one roof, there’s no coordination gap between what was designed and what gets installed.

We also use flat-rate, upfront pricing with no hidden costs, and flexible financing options are available for qualifying customers. Our reputation over eight decades has been built on recommending what a home genuinely needs, nothing more.

When Your Home Needs New Ductwork

Not every situation is the same. Here are the common triggers that bring Spokane homeowners to us for duct installation or full replacement:

First-time central HVAC installation: Homes without existing ductwork need a complete system designed and built from scratch to serve every room in the living space.
Aging or failing ductwork: Duct systems can corrode, develop persistent leaks, or collapse inward over time. When repairs become a recurring expense, replacement can restore full airflow capacity and is often the more cost-effective path.
Home additions: Adding a room or finished space requires extending or redesigning the duct system so the new square footage is served without overloading existing equipment.
Equipment replacement: When a furnace or air conditioner is upgraded, existing ductwork may be undersized or poorly routed for the new unit. Duct replacement or redesign often becomes part of the same project.

Spokane’s long heating season and warm summers put year-round demands on HVAC systems. Properly sized and sealed ductwork supports consistent comfort across both.

What to Expect During a Duct Installation

A well-executed duct installation follows a clear sequence. Here’s how we approach each project from start to finish.

Assessment & Design

Every project starts with a thorough look at the home’s layout, HVAC equipment specifications, and airflow requirements. Proper duct sizing is determined by the home’s square footage, room count, and heating and cooling load. That information drives the design, not the existing rough-in dimensions or a quick estimate.

Fabrication

Because we fabricate ductwork in-house, components are built to the specific project before installation begins. Custom pieces are cut and formed to fit the actual space, which reduces on-site modifications and helps the installed system match the design intent.

Installation & Sealing

All joints and connections are sealed during installation to prevent conditioned air from escaping into attics, crawlspaces, or wall cavities. Duct runs through unconditioned spaces are insulated to limit energy loss, which is a meaningful consideration given Spokane’s cold winters. Our team maintains clean work areas throughout and treats every home with respect.

Final Verification

Before the project is complete, we verify that airflow reaches each room as designed and that the system performs as the new or upgraded equipment requires. If something isn’t right, we address it before we leave.

How New Ductwork Improves Comfort, Efficiency, & Air Quality

The duct system does more than move air. Its condition has a direct effect on what that air carries and how much energy it takes to deliver it.

Energy Loss & Duct Sealing

Leaky ductwork lets conditioned air escape into unconditioned spaces before it ever reaches your living areas. The U.S. Department of Energy identifies duct leakage as a significant source of energy loss in homes with poorly sealed systems. New, properly sealed ductwork helps keep that air where it belongs.

Gaps and loose connections in older ductwork also let contaminants into the airstream. Dust, mold spores, and debris from attics or crawlspaces can circulate through the home when the duct system isn’t sealed. A new installation closes off those entry points.

Comfort, Equipment Strain, & Indoor Air Quality

Balanced airflow from a well-designed duct system delivers consistent temperatures to every room, reducing the hot and cold spots that often signal a distribution problem rather than an equipment problem. A duct system matched to the HVAC equipment also reduces the strain the furnace or air conditioner works under every cycle, which can support longer equipment life.

As a NADCA member, we stay current with standards in the duct cleaning services field. After installation, our Residential HVAC Maintenance Agreement is one way to protect the investment over time.
