The Fortiz Diffrence

Ductwork Isn't One-Size-Fits-All. Yours Shouldn't Be Either.

Most ductwork installed in the DMV region wasn’t designed, it was copied. A duct size gets pulled off a standard chart and run through every unit on the block, without much thought to your specific square footage or how air needs to move through your layout. That’s not how Fortiz HVAC Inc handles duct installation. Every design starts from your home’s specific footprint, and if the best duct path runs through a finished wall, we open it, build the run right, and close the wall back up ourselves. This is ductwork installation done the way it should be.

Stop Fighting Your Own Ductwork. Let's Fix It For Good.

Bad airflow isn’t a thermostat problem; it’s a duct problem. Our duct installation experts design airflow systems built around your home instead of a builder’s blueprint and drywall. Call Fortiz HVAC Inc and let’s give every room in your house the air it’s been missing.

Fortiz HVAC Inc: The Team That Opens the Wall When It's Required

We Follow the Problem, Wherever It Leads

A finished wall isn’t a stopping point for us, it’s just part of the job. Our ductwork specialists cut in, rebuild, and finish the wall themselves, so the fix goes exactly as deep as the problem does. That’s eighteen years of experience talking, the kind that means we’ve usually seen your exact issue before. Every job is fully licensed, so the work holds up to code and protects your home. And because we’re family-owned, the same people who diagnose the problem are the ones standing behind the fix, no handoffs, no disappearing after the invoice.

Is a New Duct Installation More Expensive Than a Repair?

A single repair almost always costs less than a full installation, and you deserve to know that before you call. The bigger question isn’t which one costs less today, it’s which one solves the problem you’re calling about. What tips the math is how many places your ductwork is failing, not just the price tag on the visit.

Isolated Issues Cost Less to Repair

One leaking joint or a single crushed run is a straightforward fix, priced by the problem, not a full system overhaul. Our duct repair specialists handle calls like this constantly, and when the damage is contained to one section, we’ll always recommend the faster, less expensive route instead of pushing you toward a bigger project you don’t need yet.

Multiple Failures Add Up Fast

Repeat repairs across several rooms start costing more over time than one installation would have, without ever fixing the layout underneath. We’ve seen homeowners chase the same airflow problem through different rooms for years, when one properly designed ductwork installation would have solved it for good the first time around.

Installation Solves the Root Cause

A new design addresses why your ductwork keeps failing in the first place, not just whatever symptom happens to be loudest this month. Our ductwork specialists map your entire home before recommending installation, so the fix accounts for every room fighting your system, not just the one that made you pick up the phone.

We Give You the Honest Answer First

We inspect the full system before recommending either option, so you’re never paying for more work than the problem calls for. If installation turns out to be the right fit, financing through Wisetack breaks the cost into manageable monthly payments, so budget doesn’t have to be the deciding factor. Our duct installation experts walk you through the full picture, repair or install, with an itemized estimate before any work ever begins.

Every Type of Ductwork Installation We Handle

Homes don’t move air the same way; an older rowhome, a mid-century split-level, a townhome, and a new build all play by different rules. Here’s the full lineup our ductwork specialists build, from the ground up or room by room.

Custom Sheet Metal Ductwork

Sheet metal holds its shape, seals tighter over time, and handles higher static pressure than most flexible options ever could. Long runs, tight turns, commercial-grade airflow demands, this is where sheet metal earns its keep. Our team fabricates and installs custom systems built to your home’s exact dimensions, not a generic size pulled off a shelf.

Flexible Ductwork

Flex duct is a lifesaver in tight attics and awkward joist bays rigid metal can’t squeeze through. The catch? Almost every flex failure we run into comes down to support work that wasn’t done right the first time. Fortiz HVAC Inc installs and supports flex ductwork the way it’s meant to be done, so airflow stays smooth instead of choking through sagging, kinked sections.

Insulated Ductwork Systems

Uninsulated ducts baking in a hot attic or sweating it out in a crawlspace bleed conditioned air before it ever reaches a vent. That’s money leaking out of your walls. Every attic and crawlspace run gets wrapped to spec, protecting the air you’re already paying good money to condition.

Return Air Duct Systems

An undersized return is the quiet reason half the homes in this region never feel balanced, your system’s straining to pull air back through a gap way too small for the job. Our team redesigns return pathways to match your supply side, easing pressure and letting your equipment finally breathe.

Zoned Ductwork Systems

Split-levels and multi-story homes rarely heat or cool evenly without zoning, one thermostat just can’t referee two very different levels. A zoned duct system uses dampers and dedicated controls to send the right air to the right floor at the right time. Zoning gets designed around your floor plan, not a one-size guess.

Attic & Crawlspace Ductwork

Ductwork stuck in a hot attic takes a beating from summer heat, and crawlspace runs fight moisture nonstop. Aging, leaking sections in both get ripped out, every joint sealed and every run supported so the space stops working against your system and starts working with it.

Commercial Ductwork Systems

Restaurants, retail buildouts, property management portfolios, they all need ductwork engineered for bigger loads, code compliance, and zero downtime drama. As a trusted duct contractor for commercial clients, our ductwork specialists design rooftop unit tie-ins and multi-tenant systems built for serious demand, not a scaled-up copy of a residential layout.

Custom Duct Transitions, Boots & Fittings

Sharp transitions and mismatched fittings are where airflow quietly goes to die. Our fabrication team builds custom transitions and boots on-site to match your exact duct dimensions, killing off the choke points that off-the-shelf fittings almost always leave behind.

Your Duct Problem Doesn't Need a Middleman

We Answer. We Show. We Fix.

Call once, and you’re already talking to someone who knows ductwork inside and out, not a script, not a transfer, just a straight answer from someone who’s done this work for years. That’s what a family-run team sounds like: a person who picks up, listens, and gets you taken care of from the very first call.

  • The Clock's Ticking, So Are We

    A duct problem left alone only gets pricier the longer it sits, so our crews move fast, every time. Same-day scheduling isn't a special favor here, it's just how we operate for homeowners ready to fix the room that's never felt right.

  • Emergencies Don't Wait. Neither Do We.

    Duct failures don't check the clock, and neither do we. Our emergency team steps in fast when a collapsed run or major leak threatens your system, stopping a small headache before it snowballs into a full-blown breakdown.

New Ductwork Doesn't Stay Perfect on Its Own. Here's How We Keep It That Way.

Great Installs Still Deserve a Second Look Down the Road

Fresh ductwork solves the design problem on day one, but joints settle, insulation shifts, and dust builds inside every system over time, especially in attics that swing between freezing and scorching within months. That’s where our ductwork installation experts step back in. Routine inspections catch small separations and airflow drift before they undo the precision balance we built the first time. It’s how a custom install from Fortiz HVAC Inc still performs at year five exactly like it did on day one, because we don’t disappear after the truck pulls away.

Precision Engineering From Certified Duct Installers, Never a Guess

Before any metal gets cut, our certified duct installers do the homework most companies skip entirely. We map your home’s square footage, room-by-room airflow needs, and existing layout, backed by a full dig into what’s already failing behind your walls. Nothing gets installed off a generic chart pulled from a supply house shelf. This is a system engineered around your house, by an experienced team with 20 years behind every install. That’s the Fortiz difference, and it’s exactly why homeowners choose us over anyone else in this business.

The Best Time to Start Is Before You Need It

Mild seasons are your sweet spot, comfortable temperatures mean you’re never stuck without airflow mid-install, and you’ll beat both peak humidity and the first cold snap to the punch. But if a room’s already been miserable for a season, don’t wait for the “perfect” window. Every day you hold off is another day you’re paying to condition air that never actually reaches you. Our ductwork installation experts are ready when you are, so let’s get it scheduled.

8 Benefits of Custom Duct Design & Installation

A generic duct system might technically move air, but it’ll never move it the way your home needs. Here’s what changes when our duct installation experts design your system around your house instead of a supply catalog.

Lower Energy Bills From Day One

Properly sized ductwork means your equipment stops overworking to compensate for a bad layout. That’s the kind of energy-efficient ductwork installation our customers notice on their very next utility bill, not somewhere down the line.

Balanced Airflow in Every Single Room

No more sacrificing one room to keep another comfortable. Our custom duct installation delivers air the way your floor plan calls for, so every room lands on the same temperature at the same time, that’s the standard we hold every project to.

A Quieter, Smoother-Running System

Undersized returns and mismatched fittings force your system to strain, and strain shows up as noise. Our ductwork specialists design every system to move air without whistling, banging, or rattling through the walls.

Fewer Repairs for Years to Come

Ductwork built to your home’s specific layout doesn’t fight itself the way a generic install does. It’s why most of our calls come from referrals, not repeat repairs, fewer stress points mean fewer leaks, fewer crushed runs, and fewer service calls down the road.

Equipment That Finally Hits Its Rated Efficiency

Even the best furnace or AC can’t perform to spec if the ductwork feeding it is wrong. Professional ductwork installation lets your equipment finally deliver the efficiency and comfort it was rated for.

Better Indoor Air Quality

Leaky, poorly sealed ductwork pulls in attic dust and outdoor pollutants right along with your conditioned air, compromising your indoor air quality. As a trusted duct contractor, we seal and install every run ourselves, so what you’re breathing is exactly what your system was built to deliver.

Stronger Resale Value

Buyers and inspectors notice patched, mismatched ductwork fast, and it’s a red flag during a sale. Ductwork installation done right by our team is one less thing a future buyer has to negotiate over.

The Same Team From Design to Final Seal

Every design gets built and inspected by our own duct installation experts from start to finish, the same people who mapped your home are the ones closing the wall back up. When one team designs, installs, and stands behind the whole system, nothing gets lost along the way.

From DC Rowhomes to Silver Spring Splits
to Tysons New Builds, We Know the Difference.

Ductwork across this region doesn’t follow a single pattern, and that’s something our team has picked up firsthand, not from a training manual. A prewar rowhome near the Washington National Cathedral moves air differently than a split-level in Silver Spring, which moves it differently still from a new build going up around Tysons. Our ductwork specialists factor in every one of those differences before a single tool ever comes out.

Duct Design & Installation FAQs

If a room's felt off for more than a season despite repairs, or your system runs nonstop without ever catching up, the layout is usually the culprit, not the equipment. We inspect the full duct path, not just the symptom, and give you a straight answer on repair versus redesign before any work starts.

Costs shift with home size and material, but a full duct redesign for an average single-family home typically runs $6,000–$14,000, while single-room or return-air fixes often land between $1,500–$4,000. Homes in denser areas like Arlington or Capitol Hill sometimes see different pricing due to access and permitting. We hand you a detailed, itemized estimate after inspecting your specific layout, never a guess over the phone.

Most residential duct projects wrap up in one to four days depending on how much drywall access is needed and how many rooms are involved. Since we handle drywall cutting and rebuilding ourselves, your timeline stays predictable instead of stalling while you wait on a separate contractor to show up.

Yes, whenever that's what the fix genuinely requires. Many HVAC companies stop at what's reachable from an attic or crawlspace, but if the problem is behind a finished wall, we open it, rebuild the duct correctly, and close the wall back up ourselves, so you're not stuck coordinating a second contractor on your own.

Yes, our commercial duct installation experts work with restaurants, retail spaces, and property management portfolios across neighborhoods from Tysons to Temple Hills, including rooftop unit tie-ins and multi-tenant systems. We're already handling recurring work for property management partners and actively growing that side of the business.

Our technicians are NATE-certified and EPA 608 certified, and Fortiz HVAC Inc is an ACCA member. We also hold NADCA certification for our duct cleaning services. Every technician is fully licensed to work across every jurisdiction we serve, whether that's a rowhome near Capitol Hill or a new build out toward McLean.
