Trusted Air Duct Repair for Modesto Homeowners
Leaky, crushed, or disconnected ducts waste the cool air your system works hard to produce, and in Modesto’s hot summers that loss shows up on every bill. We repair ductwork instead of cleaning around a problem, and our technicians have up to 13 years of experience with the tools commercial contractors use: Rotobrush rotary brush systems and Nikro negative-air machines. Same-day repair is available. Call (866) 256-3971. We answer 24/7.
HVAC Duct Installation
HVAC Duct Installation means designing and running a new duct system for a home that has none, or replacing a layout that was sized wrong from the start. It comes up with additions, remodels, garage conversions, and older Modesto houses whose original runs of flexible duct were sized for a smaller air handler. We plan the layout by room load, seal every joint, and pressure-check the system before we call it finished. Most whole-home installations in Modesto run $2,500 to $7,500 depending on square footage, the number of rooms, and whether the runs go through an attic or a crawlspace. The written estimate sets the final price, and before-and-after photos of the finished work go to you.
Layout and Load Planning
Every run gets sized to the room it serves, not to whatever flex duct is on hand. We map supply and return paths before cutting anything, so rooms that were always stuffy finally get the air they need.
Sealing and Pressure Testing
Joints are sealed and the whole system is tested before the job is closed out. That step catches the small leaks that quietly rob a new installation of its performance.

Air Duct Replacement
Air Duct Replacement means pulling out ductwork that’s beyond repair and installing new runs in its place. Ducts that have collapsed, been soaked by a roof leak, or torn apart by rodents usually cost more to patch than to replace. We remove the old system, inspect the plenum and connections while everything is open, and install new ductwork matched to your air handler. Typical Air Duct Replacement in Modesto runs $1,800 to $5,500 for a whole-home system, depending on accessibility and the number of vents. You get one flat price per system agreed before work starts, plus photos of the old ductwork coming out.
When Patching Stops Making Sense
If more than a few runs are damaged, or the duct insulation is failing throughout, spot repairs only buy time. We tell you plainly when replacement is the better spend.
Matching the New System to Your Equipment
New duct runs are sized to the blower you actually have. That keeps static pressure in range and protects the equipment from working against a mismatched system.
Ductwork Repair
Ductwork Repair covers the targeted fixes: sealing disconnected joints, patching tears in flex duct, reconnecting runs that have fallen off their boots, and reinforcing sagging sections. If one room never gets cool or you hear whistling at a register, a repair is usually the honest answer. We inspect the accessible system, find the failure points, and fix them with mastic and proper mechanical fastening rather than tape that fails in the heat. Small Ductwork Repair jobs in Modesto typically run $250 to $850, while multi-point repairs run $850 to $1,500. The estimate is free and sets the final price.
Locating the Actual Leak
We trace pressure loss back to its source instead of guessing at the nearest register. That means checking boots, collars, and plenum connections where leaks hide.
Sealing Methods That Last
Mastic and mechanical fasteners hold up through Modesto’s summer heat cycling where duct tape does not. We seal to a standard, then check our work with the system running.
Duct Replacement
Duct Replacement is the broader job of swapping out the duct system itself, including the trunk lines and branch runs, when the whole assembly has reached the end of its life. Old ductboard that’s crumbling, flex duct that’s crushed flat under years of attic heat, and systems built with too many turns all qualify. We scope the existing layout, quote the replacement as one flat price per system, and clean and sanitize the air handler connection before the new duct goes in. Duct Replacement in Modesto usually falls between $1,800 and $5,500 for a residential system, with the written estimate confirming the number before any work begins.
Signs the Whole System Is Due
Crumbling ductboard, pervasive mold, and crushed flex all point to replacement rather than repair. When several of these show up together, we say so honestly.
What Happens to the Old Ductwork
We remove the old material and document it with photos so you can see exactly what came out. Nothing gets left in your attic or crawlspace.
Ductwork Installation
Ductwork Installation is the work of adding new runs to an existing system, such as a duct for a new bedroom, a mini-split zone, or a return the house never had. It’s also the right call when a room was added without ducting and the system was never balanced for it. We tie the new runs into the existing trunk properly, size them to the room, and balance the system afterward so the rest of the house doesn’t lose airflow. Adding one or two runs in Modesto typically costs $450 to $1,200 per run depending on distance and access, and the estimate is free. Any indoor air quality accessories get worked in during this stage, including Aprilaire filtration and Honeywell controls.
Tying Into the Existing Trunk
New runs are cut into the trunk with proper takeoffs and sealed, not taped over a hole. That keeps the system’s pressure balance intact.
Balancing After the Work
Once the new runs are live, we adjust dampers so existing rooms keep their airflow. A room addition shouldn’t mean the rest of the house goes warm.
Brands We Service
We work with Aprilaire and Honeywell indoor air quality equipment and know where each one wears out. Aprilaire filtration cabinets and humidifiers need their media and water panels checked on the schedule the equipment calls for, and the duct connections around them are common leak points. Honeywell controls and zone dampers tie into the ductwork directly, so we check that the duct side supports what the controls are trying to do. When a job needs containment-level care, we bring Abatement Technologies equipment to keep dust out of the living space.
We finish our repairs with Guardsman products where a protective coating protects the new work. Rotobrush and Nikro systems handle the cleaning and containment side of every repair we do, which means we’re not cleaning around a problem we haven’t fixed. Whether you have Aprilaire or any other make, we can help.

AfterSigns You Need a Pro Right Now
- Rooms that never get cool. If one room stays warm while the rest of the house is fine, a duct has likely come loose or crushed. It usually gets worse, not better, and the system runs longer trying to compensate.
- Whistling or roaring at the registers. Loud airflow noise means the system is pushing against a restriction, often a collapsed run or an undersized duct. Left alone, that strain wears on the blower motor.
- Visible dust plumes from a vent. Dust blowing out of a register points to a breach in the duct near that vent. In Modesto’s dry summer air, that dust is going straight into the room.
- Rising energy bills with no change in use. A jump in your bill with the same habits often means the system is losing conditioned air through leaky ductwork. Sealing pays for itself faster than most homeowners expect.
- Musty smell when the air kicks on. Odor from the vents can mean moisture has gotten into the duct insulation. It needs a proper look, not a scented filter.
Our Process, Step by Step
- 1
Phone consultation. We ask what you’re noticing and when it started, then book a visit. Fast dispatch from 7am to 7pm, Sunday through Friday, and we answer 24/7 at (866) 256-3971.
- 2
System inspection. We open access points, check boots, collars, and the plenum, and trace airflow loss back to its source. A camera and pressure readings tell us what’s actually happening inside the ducts.
- 3
Written estimate. You get one flat price per system, with the scope spelled out before anyone touches the ductwork. No per-vent pricing and no surprises on the invoice.
- 4
Repair or replacement. We fix what we found using mastic and mechanical fastening, or install new runs where repair won’t hold. Rotobrush and Nikro equipment keeps the work area contained while we’re in it.
- 5
Verification and photos. The system gets tested with the air running, the workspace is cleaned, and you receive before-and-after photos of your own ductwork. Our work is backed by a satisfaction guarantee.
How Much Does Air Duct Repair Cost in Modesto?
Air duct repair in Modesto typically runs $250 to $1,500, with most single-point repairs landing between $250 and $850 and multi-point repairs between $850 and $1,500. A typical disconnected joint or torn flex run in Modesto runs $250 to $600 depending on attic access and how far the failure sits from the register. Whole-system replacement is a different budget, usually $1,800 to $5,500, and new runs added to an existing system run $450 to $1,200 each.
Access drives the price more than anything else. A run a technician can reach on hands and knees from a hallway access costs less than one buried at the far end of a low crawlspace. The number of failure points matters too, since each one needs its own repair and test. Duct insulation condition also counts: if the outer wrap is failing, the repair has to address that or the fix won’t hold.
To avoid overpaying, ask for the scope in writing before work starts and skip any quote that only names a price without naming the repairs. Ask whether the quote is per system or per vent. We quote one flat price per system, agreed before work starts, and show you before-and-after photos of your own ducts so you know the work was done.

Frequently Asked Questions About Air Duct Repair in Modesto
Air duct repair is the work of fixing the physical duct system: resealing disconnected joints, patching torn flex duct, reconnecting runs to their boots, and stabilizing crushed sections. It’s different from cleaning, which removes debris, because repair restores the system’s ability to move air where it should go. We often do both on the same visit, but the repair is what stops the leaking. Call (866) 256-3971 for a free estimate.
Most single-point repairs take about one to two hours on site. Multi-point repairs usually run a half day, and whole-system replacement is typically a full day depending on access. We tell you the expected window when we book the visit. If the scope changes once we’re inside the ducts, we stop and re-quote before doing more.
