Air Duct Repair in Arlington - Tested First, Written Price Second

Trusted Air Duct Repair for Arlington Homeowners

Failed ductwork wastes your money and quietly lowers the air quality in your home. A disconnected joint in the attic or a crushed flex run behind a finished ceiling sends conditioned air into crawlspaces instead of your bedrooms, and a cracked seam pulls attic dust into the supply stream. Juniper Air Duct Cleaning handles air duct repair in Arlington with professional-grade Rotobrush and Nikro HEPA-rated equipment, so the same team that identifies the problem closes it. Our technicians have up to 11 years of experience, we can often schedule same-day visits in Arlington, and every job starts with a free written estimate. Call (844) 932-0326 to book.

What sets our repair work apart is that we diagnose and fix rather than just hand you a report. That matters in Arlington’s older housing stock, where original galvanized trunks meet later flex additions, and in the newer high-rises near Clarendon and Ballston where tight mechanical chases make access the real challenge.

HVAC Duct Installation

HVAC Duct Installation means building the duct system that moves conditioned air through your home from scratch, usually during a remodel, an addition, or after a system conversion. If your house has no ducts, or the ones you have serve a floor plan that has changed since they went in, this is the work that comes before cleaning or repair. Our technicians have up to 11 years of experience and we plan runs around your actual room layout, load requirements, and available chases rather than forcing air through whatever path is easiest. We work with Air Duct Cleaning and Sealing. Pricing for this kind of installation is set per job after a walkthrough.

Planning Runs Around Your Floor Plan

Room-by-room load planning determines trunk size, branch size, and register placement before any material arrives. We account for Arlington’s mix of brick colonials, cape cods, and postwar ramblers, where return paths are often the weak point. A plan that ignores return air will leave bedrooms stuffy no matter how well the supply side is built.

Choosing the Right Duct Material

Sealed sheet metal holds up in unconditioned attic space, while flex works best on short runs with gentle bends. We match material to the location rather than using one type everywhere. Where filtration equipment is part of the plan, we work with Honeywell and Aprilaire components so the duct sizes and filter racks line up correctly.

Air Duct Replacement

Air Duct Replacement is the removal of ductwork that has reached the end of its service life and the installation of new runs in its place. It’s the right call when flex duct has collapsed or torn, when rodent or water damage has made sections unsalvageable, or when a system’s duct sizing was wrong from the start. We assess what’s actually failed, confirm it with camera inspection where access is limited, and replace the affected sections with properly sealed material. Our technicians use Rotobrush equipment to clear the remaining system so new duct doesn’t tie into a dirty one. Replacement is priced per job by written estimate, and we walk you through what’s being removed and why before work starts.

When Repair Stops Making Sense

Patching a system that has failed in six places simply moves the next failure down the line. If the duct liner is shedding, the flex is crushed beyond recovery, or the runs were undersized from day one, replacement costs less over a decade than repeated fixes. We tell you plainly which situation you’re in.

Sealing the New System Properly

New duct is only as good as its joints. We mastic-seal connections at the plenum, the trunk, and every branch takeoff, then verify the whole assembly holds pressure. That step is what separates a durable installation from a set of tubes that leaks from day two.

Ductwork Repair

Ductwork Repair covers the fixes that bring an existing system back to working order: reconnecting separated joints, resealing failed mastic, replacing torn flex sections, and correcting crushed or kinked runs in tight chases. It’s what you need when airflow has dropped, a room won’t heat or cool, or you can hear the system leaking in the attic. Our technicians find the failure point with camera inspection and pressure checks, then repair it rather than leaving you with a list of problems. This is the part of our work most duct companies skip. Pricing is set per job by the written estimate after we’ve seen the system.

The Failures We See Most

Disconnected branch takeoffs top the list, followed by crushed flex behind finished walls and failed mastic at the plenum. Less obvious are sagging runs that collect condensation and dust, which restrict flow over time. Each has a specific fix, and none of them are solved by cleaning alone.

Camera Inspection Before Any Cut

We put a camera inside the duct before opening anything. That lets us pinpoint the actual failure, so repairs stay targeted instead of turning into demolition. It also means you see the problem on screen, not just in a verbal summary.

For a full-system approach, Juniper Air Duct Cleaning handles cleaning, repair, and dryer vent work across the area, so you don’t have to piece it together from separate vendors.

Duct Replacement

Duct Replacement is a targeted swap of specific duct sections when only part of the system has failed. A single crushed run over a garage, a length of torn flex in the attic, or a rusted-out trunk section can often be replaced without touching the rest of the network. That’s different from a full system replacement and usually far less disruptive. We use Nikro HEPA-rated containment during the swap to keep dust and debris out of your living space, and we seal the new section to match the existing system. Pricing for a partial replacement is set per job after we inspect the runs.

Partial Swaps That Make Economic Sense

If the failure is isolated and the surrounding duct is sound, replacing one section is the sensible spend. We check the condition of adjoining runs before recommending any partial work, because new duct tied to failing duct simply fails sooner. Where the surrounding system is marginal, we say so.

Working Around Finished Ceilings

Many Arlington homes have ductwork buried above finished interiors with limited access panels. We plan entry points carefully and patch cleanly, so the repair doesn’t leave a visible scar. Where access truly isn’t workable, we explain the tradeoffs before any work begins.

Ductwork Installation

Ductwork Installation means adding or extending duct runs to serve a space that doesn’t currently have them, whether that’s a finished basement, a converted garage, or a new addition. It’s also the work involved in tying a new zone into an existing system. We size the new runs to match the existing layout and balance the airflow, so the added space doesn’t steal pressure from rooms that already work. Our technicians have up to 11 years of experience and we coordinate with Abatement Technologies filtration components where air quality equipment is part of the build. Pricing is set per job after a site walkthrough and a written estimate.

Matching New Runs to Existing Duct

An addition fed by undersized duct cools that room poorly and starves the rest of the house. We calculate the needed airflow and size the branch accordingly, not by eye. That matters most on upper floors, where a weak run will never feel right.

Balancing Airflow Across Zones

Once new duct is in, dampers and register sizing determine how evenly the system distributes air. We adjust after installation rather than leaving it to chance. A balanced system runs quieter and cycles less.

Brands We Service

We work with and around Honeywell components regularly. Their zone dampers and filter racks sit right in the middle of the duct system, which is often where problems start, so we know where those parts wear and how to size replacement duct to match them. We also work with Aprilaire filtration and humidification equipment and understand how its filter racks alter airflow in the runs feeding them.

Our equipment includes Rotobrush contact-cleaning systems and Nikro HEPA-rated containment, and we’re familiar with Guardsman and Abatement Technologies products as well. We don’t claim to be a dealer for any of them; what we offer is understanding of the equipment and how it interacts with the ductwork. Whether you have Honeywell, Aprilaire, or any other make, we can help.

Signs You Need a Pro Right Now

• Rooms that never reach the thermostat setting. A room that’s always cold or stuffy while the rest of the house is fine often points to a disconnected or crushed run. The fix is usually a targeted repair, but someone has to find the failure first.
• Rising energy bills with no change in usage. Leaking duct sends conditioned air into the attic or crawlspace instead of your rooms, so the system runs longer to keep up. A pressure check tells you whether the duct is the cause.
• Visible debris or dust blowing from registers. That’s a sign of a broken seal pulling from an unclean space, and it means the air you breathe has been passing through dust. Cleaning and repair usually go together here.
• Whistling or rattling at vents. Noise at a register often means restricted flow from a crushed run or an undersized branch. Ignoring it stresses the blower and shortens equipment life.
• Visible damage in attic or crawlspace. Torn flex, disconnected joints, or sagging runs are easy to spot when you look. If you’ve seen them, the repair is a decision about timing, not about whether it’s needed.

Our Process, Step by Step

1. 1
   Free estimate and walkthrough. We start by looking at the whole system, not just the complaint. You get a written estimate that sets the price per job before anything starts, so there’s no surprise invoice later.
2. 2
   Camera inspection of the duct interior. We run a camera through the runs to see what’s actually happening inside. This is where we find the crushed ends and open joints that aren’t visible from outside.
3. 3
   Pressure and airflow testing. A pressure check tells us whether the repair will hold and where air is escaping. We test before and after, so the result is measurable rather than a matter of opinion.
4. 4
   Contained repair or installation work. We work with Nikro HEPA-rated containment and Rotobrush equipment to keep debris out of your living space while the repair is underway. Sealing and material work follow the plan we agreed to.
5. 5
   Before-and-after photos and a final verification. We photograph the work and walk you through it, including the final pressure readings. You see what was fixed and get a clear account of what’s now in place.
