Air Duct Repair in Rialto - We Measure the Leak Before We Quote

Trusted Air Duct Repair for Rialto Homeowners

Ductwork fails quietly. A seam opens in a Rialto attic, a joint separates behind drywall, and the system starts pulling hot Inland Empire air into rooms you’re paying to cool. What looks like a weak AC vent is often a structural breach in the duct system itself. That’s where most Rialto homeowners discover the hard way that cleaning alone won’t fix a leaking or disconnected run. Lionheart Air Duct Cleaning handles the repair side of the equation, bringing professional-grade diagnostic equipment and the willingness to open up and fix what’s actually broken. Call (855) 356-4382 when your system needs more than a vacuum pass.

Key Takeaways:

• Air duct repair in Rialto addresses leaks, disconnections, crushed runs, and failed connections that reduce airflow and pull in attic dust.
• Lionheart offers repair as a standalone service, not an upsell, so damaged ductwork gets fixed rather than cleaned around.
• We deploy Rotobrush and Nikro systems alongside Abatement Technologies negative-air capability for contained, verifiable work.
• Every repair starts with a visual inspection, airflow measurement, and a flat price agreed before any work begins.

Roland Cifuentes built Lionheart Air Duct Cleaning around a simple frustration: most companies in the Inland Empire show up to clean ducts they already know are damaged. That’s not cleaning, and it’s not honest. Our approach is different. We diagnose the system first, show you what we found, and quote the fix. No mystery invoices, no surprise findings after the fact. If your home in Rialto needs duct repair, replacement, or full installation work, we’re equipped for the job and we’re local.

HVAC Duct Installation

HVAC Duct Installation is the process of designing and fitting an entirely new duct system to carry conditioned air from your furnace or AC unit to every register in the house. In Rialto, we frequently see this need in older homes where the original ductwork was undersized, poorly sealed, or simply worn past the point where patching makes sense. Lionheart Air Duct Cleaning handles full installation work from the plenum to the register boot, using materials sized to your system’s actual CFM output rather than whatever was cheapest when the house went up. A complete installation in the Rialto area typically falls between $2,800 and $6,500 depending on home size, number of runs, and attic access. Every installation starts with a load calculation and a visual inspection, and you’ll know the final number before we cut a single hole.

New System Sizing

One of the most common installation mistakes we correct is ductwork sized for a different HVAC unit than the one actually installed. A 4-ton system moving air through ducts designed for a 2.5-ton unit never performs. We measure static pressure and calculate airflow requirements for each room before recommending a layout, not after the drywall is done.

Material Selection for Inland Empire Attics

Rialto attics can hit 140 degrees in August, which destroys cheap flex duct within a few seasons. We install insulated flex duct rated for high-temperature attic environments and rigid metal where it serves the system better. The right material means the difference between ductwork that lasts twenty years and ductwork that collapses in five.

Air Duct Replacement

Air Duct Replacement removes and replaces existing ductwork runs that have failed, whether from age, rodent damage, moisture intrusion, or poor original installation. This is distinct from full installation in that the system layout remains the same, but the material itself gets swapped for new, properly sealed duct. In Rialto homes, we most often replace flex duct runs that have sagged, torn, or delaminated, along with damaged boots and connectors. The typical cost for a partial replacement of several damaged runs runs $900 to $2,400 depending on the length of run, attic accessibility, and whether the plenum connection needs reworking. A full-house replacement lands in the $2,200 to $4,800 range. Lionheart always shows you the damaged material we removed, so you see exactly what you paid to have replaced.

When Replacement Beats Repair

A torn seam can be patched. A run that’s crushed flat, saturated with moisture, or shredded by rodents cannot. We don’t sell replacement where a repair is structurally sound, and we don’t attempt repairs on material that’s past its service life. The distinction comes from inspection, not from a script.

Sealing and Testing After Replacement

New ductwork means nothing without proper sealing at every joint. We use mastic and UL-listed tapes applied to code, then verify airflow at the registers before we pack up. Leaky new ducts are barely better than old ones, and we don’t leave until the numbers confirm the work.

Ductwork Repair

Ductwork Repair is the targeted fix for specific failures in an existing system: separated joints, torn flex, crushed sections, disconnected boots, and failed hangers. This is the service Rialto homeowners most often need, though we also provide Air Duct Repair – San Bernardino for nearby properties, because most duct systems aren’t uniformly destroyed. They have one or two bad sections dragging down the entire air distribution. Lionheart Air Duct Cleaning diagnoses the specific point of failure using visual inspection and airflow testing, then repairs it with materials matched to the existing system. Simple repairs like a re-sealed connection or a replaced boot typically cost $275 to $650. More involved repairs involving multiple runs, re-hanging sagging duct, or rebuilding a plenum connection fall in the $650 to $1,800 range. You’ll get a flat quote before work starts, and the repair is done to code, not just made to look passable.

Finding Leaks That Aren’t Obvious

Not every duct failure is visible from the attic access panel. Disconnections inside walls, boots that detached from floor registers, and seams that opened above finished ceilings all hide from a quick look. We trace airflow loss register by register, using pressure readings and in some cases thermal imaging to locate the breach before opening anything up.

Rodent and Moisture Damage in Rialto Attics

Rialto’s older neighborhoods carry a particular problem: roof rats and squirrels find their way into attics and treat flex duct as bedding. We’ve pulled runs that were chewed through in six places. Beyond rodent repair, we check for moisture staining from roof leaks or condensation, because wet ductwork grows mold and must be replaced, not dried and taped.

Duct Replacement

Duct Replacement is the specific process of removing failed sections or full runs of existing duct and installing new material in the same location. The key difference from installation is that replacement keeps the original route and sizing unless we find a reason the original design itself was faulty. Rialto homeowners choose replacement when multiple repairs no longer make financial sense, or when the material has degraded so thoroughly that patches keep failing. The price range for duct replacement in Rialto is $700 to $2,500 for partial system replacement and $2,500 to $5,500 for a comprehensive replacement of all accessible ductwork. Lionheart gives you a clear scope, including what gets removed, what gets installed, and what the final airflow should look like.

Partial Versus Full System Replacement

Replacing everything because one run failed is unnecessary. Replacing one run every season because the rest of the system is equally shot is a failing strategy. We measure the condition of all accessible ductwork and give you an honest recommendation on where the line sits. You decide with real information.

Upgraded Materials at Replacement

Replacement is the right moment to correct material choices. If the original ducts were R-4.2 flex running through a blistering Rialto attic, we quote R-8 insulated flex or rigid duct as appropriate. The incremental material cost is modest. The difference in cooling performance and duct longevity is substantial.

Ductwork Installation

Ductwork Installation in Rialto carries a specific challenge: many homes built in the 1960s through 1980s were designed around evaporative coolers or undersized central air systems never meant for modern heat loads. Lionheart Air Duct Cleaning performs complete ductwork installation with this reality in mind, calculating actual room-by-room airflow requirements rather than copying the old layout. Full ductwork installation in a typical Rialto home ranges from $3,000 to $6,800, driven by square footage, number of registers, attic configuration, and whether we’re tying into an existing HVAC unit or a newly installed one. We don’t use one-size-fits-all pricing, and we don’t use one-size-fits-all duct design either.

Plenum and Trunk Line Construction

The heart of any installation is the plenum and trunk line construction. We fabricate transitions to match your specific air handler dimensions, seal every connection with mastic, and strap trunk lines every four feet so they never sag. Ductwork that isn’t hung correctly will fail within a few seasons regardless of material quality. We hang it to last.

Register and Boot Placement

Where air enters the room matters as much as how much air enters. We reposition or add boots where the original layout starved certain rooms, especially east-facing bedrooms that catch afternoon heat. The goal is balance across the whole house, and we verify it with airflow measurements at each register before the job is done.

Brands We Service

Lionheart Air Duct Cleaning works across the major HVAC and indoor air quality platforms found in Rialto homes. Our techs service Honeywell filtration and zoning systems regularly, understanding the wiring and control protocols that keep bypass dampers and filter cabinets working with the duct system rather than against it. When we repair or replace ductwork downstream of a Honeywell zoning panel, we verify that airflow changes don’t trip the system’s static pressure limits and cause error codes.

We’re equally comfortable with Aprilaire whole-home air cleaners and dehumidifiers, and we understand how their media cabinets integrate with return duct runs. On projects requiring containment due to heavy contamination or mold, our Abatement Technologies negative-air equipment brings remediation-grade methodology to residential work, something most Rialto duct companies simply don’t carry. Whether you have Honeywell, Aprilaire, or any other make, we can diagnose and repair the duct system feeding it.

Signs You Need a Pro Right Now

• Rooms that never reach the thermostat setting. If one bedroom stays ten degrees warmer than the rest of the house no matter what you set the AC to, a disconnected or crushed duct run is the prime suspect. Your system can’t cool a room it can’t reach.
• Dust accumulating within days of cleaning. A leaking return duct pulls unfiltered attic air, insulation fibers, and decades of accumulated dust straight into your living space. If you’re dusting twice a week, the contamination isn’t coming from outside, it’s coming from your attic.
• Higher cooling bills with no change in usage. A duct leak can waste 20 to 30 percent of your conditioned air into an unoccupied attic. Your AC works harder to cool air that never arrives. The utility bill tells the story before you see it anywhere else.
• Whistling, flapping, or popping sounds from the vents. Air escaping through a small separation whistles. Duct walls that flex while the blower runs make a rumbling or flapping sound. These aren’t quirks of an old house. They’re air moving where it isn’t supposed to.
• Vents with little or no airflow at all. A register that blows nothing while neighboring rooms blast cold air usually indicates a full disconnection or a collapsed run. The air is being dumped somewhere you can’t see, and no duct cleaning will restore that airflow.

Our Process, Step by Step

1. 1
   Inspection and measurement. We start by walking the system: registers, boots, accessible duct runs, plenum connections, and return path. We measure static pressure and airflow at each vent to establish a baseline before touching anything. This gives us a map of where the system is failing, not just a guess.
2. 2
   Findings review with you. We show you what we found, in plain terms and with photos where the problem is in a hard-to-access area. You’ll see the source of the problem, not a vague description of it. If the issue is debris-related, we’ll tell you that too, and the Air Duct Repair in Rialto work may be a simple cleaning instead.
3. 3
   Flat-price quote before work starts. You get one number for the repair or replacement scope you approved. That number doesn’t move unless you add work. No per-vent add-ons, no surprise material fees, no “discovery” charges that appear after we open the attic.
4. 4
   The repair. We cut out damaged material, rebuild connections, re-hang sagging runs, and seal everything with mastic and proper tape. If containment is required for contaminated ducts, we run Abatement Technologies negative-air through the process so debris never enters your living space.
5. 5
   Verification and documentation. After the repair, we re-measure airflow at the affected registers and confirm the static pressure changed as expected. You get before-and-after documentation. Roland Cifuentes expects every job to end with numbers that prove the fix, not just a receipt.
