HVAC Duct Installation
HVAC Duct Installation is the process of designing and installing new duct runs for homes in Alameda where existing ductwork is missing, undersized, or too deteriorated to repair. In older Alameda homes, especially Victorians and mid-century builds near Park Street and the Gold Coast, we regularly find DIY duct runs that were never sized correctly for the system’s airflow. New installation typically runs $2,500 to $6,000 depending on the linear footage and accessibility. We use rigid galvanized steel and properly sealed flex duct where appropriate, and every installation includes airflow verification with a manometer before we call the job done.
Sizing Matters More Than You Think
Undersized ducts create static pressure that shortens furnace and AC lifespan. Oversized ducts reduce air velocity, leaving rooms unevenly heated and cooled. We calculate CFM requirements per room before cutting a single section.
When Repair Isn’t Enough
If water damage, rodent infiltration, or decades of kinked flex duct have compromised more than 30% of the system, replacement costs less than patching indefinitely. We’ll show you the camera footage so the recommendation is based on what we both can see.
Air Duct Replacement
Air Duct Replacement is the removal and installation of new duct sections when existing runs in your Alameda home have failed beyond practical repair. Common triggers include flood damage in crawl spaces near the Oakland Estuary, collapsed flex duct, or asbestos-wrapped ductwork that requires careful handling. Full or partial replacement in Alameda generally costs $1,800 to $5,500, with partial jobs coming in lower. We handle disconnection, removal, and disposal, then install new materials sized to your system’s actual airflow, not the previous contractor’s guesswork.
Full vs. Partial Replacement
Not every failing system needs to be fully replaced. We often replace the supply trunk while keeping intact branch runs, which saves money without compromising performance. The inspection camera tells us what can stay.
The Contamination Factor
Ductwork that has been soaked by standing water or badly infiltrated by pests can’t be cleaned back to safe condition. Replacement removes the reservoir of contamination rather than trying to scrub around it.
Ductwork Repair
Ductwork Repair in Alameda fixes the specific failures that let your conditioned air escape before it reaches a single register. The most common issues we see in homes across the Fernside and Bay Farm Island neighborhoods are separated joints, punctured flex runs, crushed sections under crawl space foot traffic, and rusted-through return plenums. Ductwork repair costs in Alameda typically run $250 to $800 depending on how many sections need attention. Our approach starts with a full inspection using a rotating brush camera, then we map the leaks and show you exactly what we found before quoting the fix.
What Actually Fails
Flex duct gets punctured by screws, crushed by storage in attics, and chewed through by rodents. Rigid ducts fail at the joints where tape dries out and separates. Identifying the failure type determines whether we patch, reconnect, or replace the section.
Repair Before You Clean
Cleaning a leaking duct system pulls attic and crawl space air into the airstream. We recommend repairing major leaks first, then cleaning, so the cleaning work actually holds. If an Air Duct Repair in Alameda technician finds leaks during a cleaning appointment, we’ll document them and quote the fix on the spot.
Duct Replacement
Duct Replacement is the targeted removal of failed duct sections and installation of new, correctly sized runs in their place. For many Alameda homes, particularly those with crawl spaces that see seasonal moisture, rusted or collapsed metal ducts are the primary culprit. Duct replacement in Alameda typically costs $1,500 to $5,000 depending on the footage and access difficulty. We use an airflow meter to confirm the existing system’s requirements before selecting replacement materials, so the new ducts match the system rather than the old problem.
Why a Section, Not the Whole System
Most homes only need the failed sections replaced, not the entire network. Replacing the failed return drop or a crushed supply run often restores system balance. We don’t sell full replacements unless the camera evidence justifies it.
Material Choices That Hold Up
We install galvanized steel for most runs and properly supported flex where routing requires it. Every connection gets sealed with mastic, not tape, because mastic doesn’t dry out and separate the way tape does.
Ductwork Installation
Ductwork Installation covers complete new duct system design and installation for additions, ADUs, or whole-home remodels in Alameda. With so many accessory dwelling units going up across the island, we’ve installed dedicated duct systems for dozens of backyard cottages and garage conversions. Full ductwork installation in Alameda typically runs $3,000 to $7,500 depending on square footage and the number of registers. We handle the load calculation, duct layout, register placement, and final airflow balancing, and we use Honeywell and Aprilaire filtration components when the project calls for air quality upgrades at the same time.
New Construction Needs Airflow Math
A properly installed duct system starts with a manual calculation of room-by-room CFM requirements. We don’t install based on rules of thumb. We measure, calculate, and then install, which is why our installs don’t leave one bedroom hot and another freezing.
ADUs and Garage Conversions
Accessory dwelling units need their own properly designed ductwork, not a flex run tapped off the main house. We’ve handled ADU duct installations across Alameda and know what the local building department expects to see.
Brands We Service
Everclear Air Duct Cleaning works with all duct types and system configurations. Our technicians install and service galvanized steel and flex duct systems alongside filtration components from Honeywell and Aprilaire, and we carry the materials and media to keep those systems performing. If you have a Honeywell whole-home filtration cabinet, we can replace media, calibrate the airflow sensor, and confirm the system is actually filtering, not just humming.
We also use Abatement Technologies negative air and containment equipment during repair jobs that involve heavily contaminated ductwork, which keeps debris from spreading through your living space while we work. Whether your system includes Nikro cleaning equipment, Honeywell filtration, or any other make, we can help with the ductwork that carries the air.

AfterSigns You Need a Pro Right Now
- Rooms that never reach the thermostat setting. If one bedroom is consistently five degrees off from the rest of the house, a disconnected or crushed duct is often the cause. The system runs longer to compensate, which raises your energy bill every month it goes unfixed.
- Visible dust streaks around registers. Dark lines around supply vents mean the duct is pulling attic or crawl space air into the airstream. You’re breathing whatever is in those spaces, including insulation fibers and pest debris.
- A sudden jump in your energy bill. When conditioned air escapes into unconditioned space, your HVAC system runs more cycles to hold temperature. A 20% to 30% bill spike without a weather or usage change points to duct leakage.
- Musty or stale odors when the system runs. Air leaking from a crawl space carries moisture and mold spores with it. If the smell only appears when the blower kicks on, the ductwork is the delivery mechanism.
- You can hear air moving where it shouldn’t be. A whistling or rushing sound from walls, ceilings, or the crawl space means air is escaping through a gap or separated joint. That’s conditioned air you’re paying to heat or cool your attic.
Our Process, Step by Step
- 1
Inspection with camera documentation. We run a rotating brush camera through the accessible sections of your duct system and record what we find. You see the footage before any repair is quoted, so the recommendation is based on evidence, not a sales pitch.
- 2
Leak mapping and airflow measurement. We use a manometer and smoke puffer to identify leakage points and measure static pressure. This tells us whether the issue is a single failed joint or a systemic sizing problem.
- 3
Flat quote with a clear scope. We provide one price per repair scope before work starts. No per-vent pricing games, no adding line items once the van is in your driveway. The quote covers materials, labor, and disposal.
- 4
Sealed repair with appropriate materials. We reconnect, patch, or replace failed sections using mastic sealant and materials matched to the existing system. Every repair gets a post-work camera pass so you can see the fixed section.
- 5
System verification before we leave. We re-measure static pressure and airflow at the affected registers to confirm the repair restored proper air movement. You get the numbers, not just a verbal assurance that it’s fixed.
How Much Does Air Duct Repair Cost in Alameda?
Air duct repair in Alameda typically costs between $300 and $900 for most jobs. A single disconnected joint or punctured flex section usually lands on the lower end, while repairs requiring multiple access points, crawl space work, or replacement of rusted metal sections push toward the higher end. Full Air Duct Repair in Berkeley or replacement work runs $1,500 to $5,500 depending on footage.
What affects the price: accessibility of the ductwork, the number of failed sections, whether the system is flex or rigid metal, and whether the repair requires containment equipment for contaminated areas. Homes with low-clearance crawl spaces or attic-mounted systems take longer, which is reflected in labor.
To avoid overpaying, ask any contractor for camera footage of the damage before approving the quote. A repair that’s quoted on visual evidence is far less likely to balloon once work begins. Our free estimates include the inspection, the camera documentation, and a flat price for the scope of repair, so you can decide with the facts in front of you.
