Custom Sheet Metal Fabrication & Ductwork Built for Southeast Alaska

The Part of Your HVAC System Nobody Sees, But Everybody Feels

Nobody thinks about ductwork until something feels off. But what’s hidden behind your walls matters just as much as the furnace or heat pump itself. A good HVAC system depends on ductwork that moves air exactly where it needs to go. If it doesn’t fit right, the whole system works harder than it should, and you end up paying for it in energy bills and rooms that never quite feel comfortable.

At Fischer Mechanical, we build custom sheet metal fabrication and ductwork for homes and businesses throughout Juneau and Southeast Alaska. Owner Billy Fischer and his team have more than 33 years of combined experience, and they build ductwork that fits your building instead of forcing your building to fit some standard part. Whether you’re building new, remodeling, or replacing ductwork that’s seen better days, we build it around your space.

Why "Close Enough" Ductwork Costs You More Than You'd Think

A lot of homeowners don’t realize how much bad ductwork can drag down an entire HVAC system. Air leaks, wrong sizing, extra bends, transitions that don’t quite fit, all of it adds up to weaker airflow, hot and cold spots from room to room, and equipment that’s stuck working overtime just to keep pace.

That matters even more up here. Southeast Alaska heating systems run for most of the year, and they have to hold up against constant moisture, coastal humidity, and weather that changes its mind by lunchtime. On top of that, no two buildings are alike. Ceiling heights, crawl spaces, and mechanical room limitations vary from one property to the next. That’s exactly why custom-built ductwork usually beats trying to squeeze a standard part into a space it was never meant for.

Adding a new heat pump? Replacing an old furnace? Upgrading commercial ventilation? Ductwork built for your space helps you get better airflow, better efficiency, and an install that holds up for years instead of months. Curious what that looks like for your property?

Customized

Fabrication isn’t something we tack on at the end of a job. It’s baked into how we build every HVAC system from day one. Each project starts with a close look at your property, its layout, its airflow needs, and what the equipment actually requires. From there, we build custom transitions, plenums, offsets, and specialty fittings made for that specific job, not a generic one.

Built Locally

Billy and Kasen were both born and raised in Juneau, so they’ve run into the kinds of challenges Southeast Alaska throws at HVAC systems more times than they can count. Tight crawl spaces. Older buildings with layouts that don’t follow any rulebook. Commercial jobs where the standard part just won’t work, no matter how you angle it.

Not Shipped In A Box

Building locally also means we move faster when a project needs something unusual. Instead of waiting weeks on a special order from outside Alaska, we build a lot of what we need right in our Juneau shop, so your project stays on schedule without anyone lowering the bar on quality. Whether we’re fabricating ductwork for a family home in Juneau or flying around Southeast Alaska, the craftsmanship stays the same.

Frequently Asked Questions

What's the difference between custom fabrication and standard ductwork?

Standard ductwork comes pre-made in fixed sizes and shapes, which works fine for some buildings but not all of them. Custom fabrication means we design and build the ductwork, transitions, and fittings around your specific property instead of forcing your building to work with whatever size happens to be on the shelf.

A poorly fitted duct system forces your HVAC equipment to work harder than it should, which usually shows up as higher energy bills and uneven temperatures. Custom fabrication gives you airtight, properly sized ductwork built for your space, which helps your system run the way it’s supposed to.

Since we build most of our components right here in our Juneau shop, we’re not waiting on shipments from Anchorage or Seattle. That usually means a faster turnaround than contractors who rely entirely on pre-manufactured parts, though the exact timeline depends on the size and complexity of your project.

Yes. We build custom sheet metal fabrication and ductwork for homes, remodels, new construction, and commercial buildings throughout Juneau and Southeast Alaska.

Often, yes. Older homes and buildings sometimes have layouts, ceiling heights, or crawl spaces that standard parts just don’t work with. Custom fabrication lets us build transitions and fittings made specifically for those tighter or unusual spaces.

We work with the sheet metal and components best suited to your project and Southeast Alaska’s coastal climate, since constant moisture and humidity can wear down materials that aren’t built to handle it. We’ll walk you through the right choice for your specific situation.

Yes. We’ll take a look at your project, explain what we recommend, and give you a straightforward estimate with no pressure attached.

Absolutely. We regularly travel to Sitka, Haines, Hoonah, and other Southeast Alaska communities for fabrication and installation work. If you’re not sure whether we cover your area, just reach out.

It depends on the project. Custom fabrication can cost more upfront than off-the-shelf parts, but a properly fitted system often saves money over time through better efficiency and fewer repairs down the road. We’ll give you an honest estimate so you can weigh the tradeoffs.

Yes. We’re happy to share local references so you can hear directly from past customers before deciding to work with us.
