Why Israel Sheet Metal
Family-owned since 1992 — three generations of the López family. José and Oralia López founded the shop in Canutillo in 1992; their son Israel López runs it today — so the name on the truck is the family you deal with.
Sheet metal is in our name, and custom fabrication is the craft Israel Sheet Metal was built on. For 34+ years we have designed, fabricated, and installed ductwork for El Paso and Las Cruces homes out of our own shop in Canutillo — which means we are never waiting on an outside vendor and never forcing an off-the-shelf part to fit a job it was not made for.
Leaky or undersized ductwork quietly wastes a large share of the air you pay to cool — a real cost in El Paso's extreme summers. Air that escapes into an attic is air you bought at full price. It also explains the symptoms homeowners rarely connect to duct at all: one room that never keeps up, weak airflow at the far vents, dust that reappears days after cleaning, and a system that runs and runs without the house ever feeling right.
Seal or replace is a judgement we make after looking, not before. Duct in sound condition with leaks at the joints and connections is usually worth sealing — recovering cooling capacity and lowering the bill without touching the equipment. Duct that is crushed, corroded, disconnected or simply too small for the system it now serves is a replacement, because sealing an undersized run only makes it a well-sealed undersized run.
Our in-house shop fabricates custom rectangular and round duct, spiral duct, transitions and plenums, so a repair or a new run is built to the measurements of your house. That capability is also why swamp-cooler-to-refrigerated conversions go smoothly here: most conversion homes need new or modified duct to carry refrigerated air, and we build it ourselves rather than scheduling around a supplier.
Commercial work — kitchen exhaust hoods, stainless fabrication, RTU curb adapters, tenant build-outs — is handled on our <a href="/services/commercial-sheet-metal-fabrication/" style="color:var(--lime-2);text-decoration:underline;">commercial sheet metal fabrication</a> page. Family-owned, licensed in Texas (TACLA00118528E) and New Mexico (#359536), BBB A+, and serving the borderland since 1992.
Duct symptoms and what they point to
Most homeowners call about comfort, not duct. These are the symptoms that usually turn out to be a duct problem.
| What you notice | Likely duct cause | Usual fix |
|---|---|---|
| One room never keeps up | Undersized, crushed or disconnected run to that room; no return path | Assess that run; resize or replace it. See our guide on one room being hotter than the rest. |
| Weak air at the far vents | Leaks along the run, or duct too small for the system's airflow | Seal the joints, or replace runs that are undersized for the equipment. |
| High bills with a healthy system | Conditioned air leaking into the attic before it reaches a room | Seal — often recovers capacity without touching the equipment. |
| Dust returns days after cleaning | Leaks pulling attic and wall-cavity dust into the return side | Seal the return side; check filter fit. |
| New system still doesn't cool right | Old duct cannot carry what the new equipment produces | Duct modification or new runs, fabricated to the system's actual airflow. |
| Rattling or booming when it starts | Loose connections or panels flexing under pressure | Reinforce and reseal; check for restricted returns. |
We assess before recommending, and quote any duct repairs free.
How we decide
| Duct condition | What we recommend |
|---|---|
| Sound metal, leaking at joints and connections | Seal. This is the cheapest real gain available in most El Paso homes. |
| Crushed, corroded or disconnected sections | Replace those runs — sealing damaged duct does not restore airflow. |
| Undersized for the equipment it now serves | Replace or resize. A well-sealed undersized run is still an undersized run. |
| Missing runs after a swamp-cooler conversion | Fabricate new runs in-house, sized for refrigerated air. |
Five steps
from measure to airflow.
Duct is measured, drawn, built and then verified — the last step is the one most companies skip.
We look at the runs, the returns and the symptoms — uneven rooms, weak vents, high bills — and measure rather than estimate.
Sound duct with leaking joints gets sealed. Crushed, corroded or undersized duct gets replaced. You get the reasoning, and a free estimate.
Rectangular, round, spiral, transitions and plenums built in Canutillo to your measurements — no waiting on an outside vendor.
Runs installed and sealed properly at every joint and connection, so the air you paid to cool reaches the room.
We check that the air is actually arriving where it should before we call the job done.

Ductwork & Sheet Metal — FAQ
Yes — custom sheet-metal fabrication is our specialty. We build duct on-premises in our Canutillo shop, so your system fits right the first time with no waiting on an outside vendor.
Yes. We clean, seal, and repair ductwork across El Paso and Las Cruces. Sealing leaks alone can recover a significant share of the cooled air a leaky system wastes — lowering your energy bill without replacing any equipment.
We inspect before recommending. Duct that is structurally sound but leaking at the joints is usually worth sealing. Duct that is crushed, corroded, disconnected, or simply too small for the system it serves needs replacing — sealing an undersized run only makes it a well-sealed undersized run. Call (915) 877-2284 and we'll assess it and quote any repairs free.
One room that never keeps up with the rest, weak airflow at the far vents, dust that returns within days of cleaning, high bills from a system that seems otherwise healthy, or a newly installed system that still doesn't cool properly. All of those point at the duct rather than the equipment.
It means tighter fit, faster turnaround, and no dependence on a third-party supplier's schedule or tolerances. An AC system is only as efficient as the ductwork behind it — duct built to your specific job delivers the rated comfort instead of leaking it into attic space.
Absolutely. In fact, it's one of our core strengths. Most swamp-cooler homes need duct modifications or new runs to support a refrigerated system, and because we fabricate the duct in-house, we can complete the whole conversion without waiting on a separate vendor.
Yes, but that work lives on its own page. Commercial kitchen exhaust hoods, stainless fabrication, spiral duct, RTU curb adapters and tenant build-outs are covered under commercial sheet metal fabrication — this page is about ductwork for homes.
