Recognize any of these? New ducts could be the upgrade you’re missing.
Poorly designed or damaged ducts can't push air to upper floors. Replacement balances the pressure.
Take a flashlight to your attic. If you spot holes, disconnected joints, or crushed sections, your air is leaking out.
Leaky ducts waste up to 30% of your conditioned air. Your HVAC works overtime while your home never feels quite right.
Replace rodent-damaged ducts to eliminate droppings and biohazards from your air supply.
Old ducts trap dust, pollen, and mold for decades, then blow them into your home every time the system runs.
Existing ducts don't fit your addition. New branches add comfort without robbing airflow.
Duct replacement isn’t just swapping out old flex for new. We use heavy-duty, insulated duct board and R-8 flex with reinforced inner cores materials that resist crushing and prevent condensation. Every joint gets mastic sealant, not just duct tape that dries out in a year. We hand-seal each register boot to the floor or wall so conditioned air goes into the room, not the joist bay. Then we pressurize the system and test for leaks with a manometer. If it loses more than 5% of pressure, we find the leak and seal it again.
Jurupa Valley homes come in every shape — single‑story ranches, two‑story boxes, old farmhouses with additions. We calculate exactly how much air each room needs based on square footage, window placement, and insulation levels. Undersized ducts choke your system, making it run longer and die sooner. Oversized ducts waste energy and leave air sitting stagnant. We get the math right so every register delivers the right amount of air at the right speed.
Duct replacement gets dusty, but you won’t see any of it. We lay down drop cloths, seal off registers while we work, and use negative air machines to catch debris before it spreads through your home. We also coordinate with your AC technician if your system needs to be re‑matched to the new duct layout. When we’re finished, we haul away every piece of old ductwork, patch any access holes we cut, and walk you through the improvements you’ll notice immediately.

Most homeowners don’t think about ductwork until something feels wrong. But hiring the wrong crew can make uneven temps and high bills even worse. We do duct work right, designed properly, sealed tight, and tested before we leave.
We don't guess from the driveway. We crawl every corner of your attic or crawlspace, photograph damaged sections, and show you exactly what needs replacing before we quote a single dollar.
Ductwork problems look different in a home versus a retail space or office. We handle both from tight attics in Jurupa Valley houses to exposed duct runs in small businesses.
Our quote covers demolition, new ducts, sealing, insulation, haul‑away, and cleanup. If we find an unexpected issue like a structural block, we stop and call you before adding any charge.
We don't just hope airflow improves. We measure pressure at every register, check for leaks with a digital test, and show you before/after numbers so you see the proof with your own eyes.

They’re a small family-owned business that clearly takes pride in doing things the right way. They’ve come out to my place three different times for repairs and maintenance, and every time they were respectful, explained what they were doing, and followed through exactly on what they promised.

I highly recommend Armando and his crew if you need reliable HVAC service.Posted on Jennifer GerrityTrustindex verifies that the original source of the review is Google.

How We Turn Duct Replacement into a Smooth Process
Before touching anything, we test your current airflow at every register and measure static pressure in your ducts. Those numbers tell us exactly where the problems are hiding.
You get a simple duct layout diagram, a written materials list, and a start time that fits your schedule. No hidden prep just clear the work zone. Everything else is on us.
After sealing and insulating new ducts, we run system for 20 minutes and retest register. Then we clean every scrap of old ductwork and leave your home as we found it.
Cleaning removes dust and debris but won’t fix torn sections, crushed flex duct, or disconnected joints. If you see visible damage, feel air leaking when you touch the duct, or notice your energy bills creeping up despite regular maintenance, replacement is the better long-term solution. We can inspect and tell you for sure during a free estimate.
Most single‑story homes take one full day about six to eight hours from setup to cleanup. Two‑story houses or homes with complex attic layouts might need a second morning. We give you a clear timeline before we start so you can plan your day around the work.
Absolutely. Leaky ducts can waste 20 to 30 percent of your conditioned air before it ever reaches your rooms. After replacement, your system runs shorter cycles and doesn’t have to work as hard. Most Jurupa Valley customers see a noticeable drop within their first two billing cycles.
We use R‑8 insulated flex duct as our standard it’s energy efficient and flexible enough to fit tight spaces. For homes with crawlspace moisture issues, we recommend rigid sheet metal with external insulation. We’ll show you samples and explain the pros and cons of each option before you decide.
Usually not. Most ductwork runs through attics, basements, or crawlspaces, so we access everything from above or below. On rare occasions when a duct is buried inside a hard‑to‑reach wall cavity, we’ll discuss the least invasive option first. We always patch and paint any small access holes we do create.
Yes , and that’s one of the first things customers notice. Old fiberglass ducts shed tiny particles into the airstream, and leaky ducts pull dust from your attic into your living space. New, sealed ducts stop both problems. You’ll likely dust half as often after replacement.
Yes — every neighborhood including Pedley, Rubidoux, Mira Loma, Glen Avon, and Indian Hills. If you have a Jurupa Valley address, we’ll come out, inspect your ductwork for free, and give you a detailed replacement quote with no obligation to move forward.
Call us or fill out the form on this page. We’ll ask a few quick questions your home’s age, what kind of heating and cooling system you have, and any comfort issues you’re dealing with. Then we’ll schedule a time to crawl through your attic, take measurements, and give you a written quote.
New ductwork means even temperatures, lower energy bills, less dust, and a healthier home. We make the process clean, honest, and surprisingly simple.
