Trusted Air Duct Repair for Brentwood Homeowners
Our Air Duct Repair in Brentwood typically costs between $250 and $850 for most common fixes, from sealing small leaks to replacing damaged duct sections. The work is usually completed in a single visit, and Duct Cleaning Brentwood handles everything from diagnosis to finished repair with professional-grade equipment, not consumer shortcuts. We repair what we find, not just clean around it.
Rick Sommer leads our team with a focus that most HVAC generalists can’t match: ducts are all we do. In Brentwood’s older homes, we regularly uncover disconnected runs, crushed flex duct, and rodent damage that has been silently pulling attic air into living spaces for years. Call (833) 631-4988 and we’ll diagnose the problem and give you a flat price before any work begins.
HVAC Duct Installation
HVAC Duct Installation is the process of designing and fitting an entirely new duct system when a home has none, or when the existing layout is too compromised to salvage. In Brentwood, this is common during major remodels, garage conversions, or when homeowners discover their 1950s-era ductwork was never properly sized for modern heat pump systems we see throughout the Westside, including areas where Bel Air Air Duct Repair is frequently needed.
We plan every installation around the specific demands of your home’s square footage and layout, then fabricate and hang the system with sealed connections at every joint. Pricing for new HVAC duct installation in Brentwood generally runs $3,500 to $9,000 depending on the number of runs, accessibility, and whether the space is a crawlspace, attic, or slab foundation.
Sizing and airflow design
Correct duct sizing is the difference between a system that conditions every room evenly and one that leaves the back bedroom eight degrees warmer all summer. We calculate static pressure and airflow requirements before cutting a single piece of metal.
Sealed and insulated from day one
Every joint gets mastic-sealed, not just taped, and all attic runs are insulated to prevent condensation during Brentwood’s cool, damp winter mornings. That detail keeps your new system efficient for decades, not just the first season.

Air Duct Replacement
Air Duct Replacement means removing and discarding damaged, contaminated, or collapsed duct sections and installing new material in their place. We recommend this route when ductwork has been crushed by attic storage, chewed through by rodents, or saturated by a roof leak that turned insulation into a mold source.
Brentwood homes built before 1980 often have original galvanized ductwork that is now rusted at the seams or wrapped in deteriorating asbestos-era insulation. Replacing those runs restores proper airflow and eliminates the dust, fiberglass particles, and musty odors that keep circulating through your rooms. Whole-home air duct replacement typically runs $2,800 to $7,500 based on the length of runs and access difficulty.
Flex vs. rigid replacement
We stock both insulated flexible duct and rigid metal, and we’ll recommend the right material for each section. Flex works well for short, awkward runs; rigid metal handles main trunk lines with less airflow resistance.
When replacement beats repair
If more than 40% of a given run is damaged or the interior liner is breaking down, repair becomes false economy. We’ll show you photos of the damage and let you make the call with real evidence in hand.
Ductwork Repair
Ductwork Repair addresses specific failures in an existing system: separated joints, punctures, crushed sections, loose hangers, and leaking supply boots. This is the most common service we perform in Brentwood, because most duct systems here are structurally sound but have developed leaks that quietly bleed conditioned air into attics and crawlspaces.
We locate every breach using the same diagnostic approach contractors trust: visual inspection of every accessible run, pressure testing where needed, and airflow measurement at each register. Once we find the problem, we fix it with mechanical fasteners and mastic sealant, not duct tape. Most ductwork repairs in Brentwood fall between $180 and $600 per affected area.
Leak sealing and joint repair
A separated duct joint can lose 20 to 30 percent of your conditioned air before it ever reaches the room. We reseal every accessible joint and add support strapping where ducts have sagged and pulled apart.
Register and boot fixes
Loose floor registers and disconnected boots let dust, insulation, and crawlspace air into your home. We resecure boots to the subfloor and seal the gap so what comes out of your vents is only what should be there.
Duct Replacement
Duct Replacement is frequently confused with air duct replacement, and the distinction matters for your estimate. In our scope, duct replacement refers to replacing specific duct runs or a significant portion of the system rather than a full tear-out, and it is the right call when several sections have failed but the main trunk line is still solid.
This is a common scenario in Brentwood neighborhoods like Brentwood Glen and Crestwood Hills, where mid-century homes have had piecemeal additions and remodels that left a patchwork of original and added ductwork, similar to what we address with Air Duct Repair – Wilshire Center. We replace the failing runs with properly sized, sealed, and insulated duct, and tie everything back into the healthy portions of your system. Expect duct replacement to run between $900 and $3,200 for typical multi-run projects.
Partial system replacement
If your main trunk is solid but branch runs to individual rooms are damaged, partial replacement gives you most of the benefit of new ductwork at a fraction of the full-system cost. We’ll evaluate run by run and recommend only what actually needs to go.
Reconnecting after remodels
We see plenty of Brentwood homes where a contractor knocked out a wall and left a duct run dangling or capped. We rebuild those runs and restore proper airflow to rooms that have been starved since the remodel finished.
Ductwork Installation
Ductwork Installation differs from HVAC duct installation in one key respect: this is about adding new duct runs to an existing system, not designing a full system from scratch. People in Brentwood ask for this when they finish a basement, convert a garage into an ADU, or add a room that never received proper airflow.
We tap into the existing plenum or trunk line, size the new run for the room’s heat load, and install it with the same sealing and insulation standards we apply to full systems. Typical ductwork installation for a single added room in Brentwood runs $600 to $2,200 depending on run length and whether the space is accessible from an attic or crawlspace.
Adding runs to existing systems
Not every HVAC system has the capacity to serve an extra room, so we verify static pressure and blower output before adding runs. If your system can’t handle the load, we’ll tell you straight rather than install ductwork that will never deliver.
ADU and addition ductwork
Brentwood’s ADU wave means lots of new conditioned space that needs ductwork tied in correctly, much like the Air Duct Repair in Sawtelle projects we handle. We work with your contractor or directly with you to get the new space conditioned without compromising the existing rooms.
Brands We Service
We service and install Rotobrush and Nikro equipment on every cleaning job, but our repair work goes further. When we open a duct system, we’re looking at the components that move air through it, and we frequently replace or upgrade Honeywell and Aprilaire components in the same visit. That means a single call can fix a leaking duct and address the filtration or humidity control that caused the problem in the first place.
For contaminant control in problem systems, we stock Abatement Technologies products that are built for genuine air-quality work, not surface-level fixes. Whether your system uses standard galvanized duct, flex duct, or any other configuration, our repair and replacement work is done to the same standard regardless of brand origin.

AfterSigns You Need a Pro Right Now
- Rooms that never reach the thermostat setting. If your living room reads 72 but the back bedroom sits at 78 all afternoon, you likely have a disconnected or crushed duct run. The air is being conditioned, but it is not arriving where you need it, and that is a mechanical failure, not an HVAC sizing issue.
- Dust accumulating within days of cleaning. When ducts leak, they pull attic and crawlspace air directly into your living space along with whatever dust, insulation, or pest debris is up there. Consistently rapid dust buildup on furniture usually traces back to a breached return-side duct.
- Musty or stale smell when the system runs. That odor usually means moisture has found its way into a duct, often through a separated joint in a crawlspace or a saturated section of insulation. The smell is the warning sign; the mold growth that follows is the real problem.
- Visible damage in the attic or crawlspace. If you have been up there and seen crushed flex duct, hanging or separated metal, or rodent droppings around your ductwork, the system has already failed in that location. The longer it runs, the more conditioned air you lose.
- Energy bills that climb without explanation. A 20 to 30 percent duct leak means your system runs longer to hit the same temperature, and that cost shows up every month on your bill. Duct leakage is one of the most common causes of unexplained energy spikes in Brentwood homes.
Our Process, Step by Step
- 1
System inspection and diagnosis. We start by walking every accessible duct run with a high-lumen inspection camera and checking airflow at each register. We are looking for separation, compression, contamination, and any signs of moisture or pest activity.
- 2
Pressure and airflow measurement. Using a digital manometer, we measure static pressure across your system and compare register output room to room. This tells us how much air is leaking and which runs are the biggest offenders.
- 3
Flat-price proposal with photo evidence. Before any repair work begins, you see the damage on our camera screen and get one flat price for the full repair. There is no hourly billing and no surprise line items when the job is done.
- 4
Repair or replacement work. We cut out the damaged section or reseal the failed joint using mastic and mechanical fasteners. If replacement is the better call, we install correctly sized duct and insulate every run in unconditioned space.
- 5
Verification and before-and-after documentation. After the repair, we re-measure airflow at the affected registers and show you the before-and-after photos. You see exactly what was fixed and confirm the airflow numbers have actually improved.
How Much Does Air Duct Repair Cost in Brentwood?
A typical air duct repair in Brentwood runs $250 to $850 for the most common scenarios: resealing separated joints, patching punctures, reconnecting fallen runs, and securing loose register boots. If the damage is extensive enough to require replacing several duct sections, expect the project to land between $900 and $3,200. Full air duct replacement across an entire Brentwood home generally falls in the $2,800 to $7,500 range depending on square footage and attic accessibility.
What moves the price is access: a wide, walkable attic keeps costs low, while a crawlspace with 18 inches of clearance adds labor hours to every step. Duct length and diameter matter too, as do the number of damaged runs and whether we are working with flex duct or rigid metal. The most important thing we can tell you is this: we give one flat price per project before work starts, agreed to in writing. No per-vent pricing games, no inflating the invoice once the van is in your driveway.
To avoid overpaying, ask any contractor to show you the damage on camera before you approve the work. If they will not show you what they are fixing, walk away. Our estimates are free, include a full diagnostic report, and carry no obligation. Call (833) 631-4988 and we will give you the real number for your home, not a teaser rate.

Yes, we service and replace Honeywell and Aprilaire components including zoning dampers, air cleaners, humidifiers, and filtration housings. Since these parts live inside or adjacent to your ductwork, we often identify failing components during a repair visit and can address them in the same appointment. That saves you a second service call and keeps your entire air delivery system working together.
We prioritize urgent cases like fully collapsed ducts, active pest infestations in ductwork, or water damage from a roof leak that is spreading into the system. While we are not a 24/7 operation, we do hold same-week slots for homeowners dealing with active damage that will worsen quickly. Call us and describe what you are seeing; we will give you an honest assessment of how fast it needs attention.
Every repair and replacement we complete is backed by a workmanship warranty covering the sealed joints, new duct sections, and installed components. If something we fixed fails within the warranty period, we return and correct it at no charge. We also provide documentation of all work performed, including before-and-after photos, so you have a record of exactly what was done.
Clear a path to your attic access or crawlspace entry point and move any stored items near the furnace or air handler so we have working room. Turn off your HVAC system about 30 minutes before we arrive if you can. That is really all we need; we bring our own drop cloths, lighting, and every tool required for the job.
