Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

Air Duct Repair in Loma Linda
Air Duct Repair in Loma Linda means fixing the leaks, separations, and corrosion that let conditioned air escape into attics and crawl spaces, and it’s especially common in the mid-century ranch homes that dominate this city’s older neighborhoods. Because much of Loma Linda’s core housing is mid-century ranch stock with original galvanized steel ductwork from the 1950s – 70s, cleaning here is as much about not damaging brittle, snag-prone metal as it is about debris removal. Old galvanized runs need gentler agitation tools and lower-contact methods than the flexible ducting going into newer builds near the university. A typical Air Duct Repair in Loma Linda runs $400 – $900 depending on accessibility and the extent of separation or corrosion.
Sealing Leaky Galvanized Runs
Original steel ducts in Loma Linda’s ranch-era homes often separate at the seams after decades of thermal expansion. We apply duct sealing mastic, a thick, fiber-reinforced compound that bridges gaps without the toxic off-gassing of older tape adhesives. The result is sealed airflow and no chemical smell pushed through your vents.
Corrosion Patching in Humid Crawl Spaces
Even in Loma Linda’s dry climate, occasional plumbing leaks or ground moisture in crawl spaces can rust out the bottom of galvanized trunk lines. We cut out corroded sections and splice in new galvanized or flexible ducting, then seal the joints properly. The repair is photographed before and after for your records.
Ductwork Cleaning in Loma Linda
Ductwork Cleaning in Loma Linda removes the accumulated dust, pollen, wildfire ash, and debris that circulates through your HVAC system and back into your living space. Because Loma Linda sits in the Inland Empire with hot, dry summers and Santa Ana wind events that drive dust and wildfire smoke into homes, duct cleaning here is critical for allergy and asthma relief. The area also experiences occasional high winds that can infiltrate outdoor debris through HVAC systems. A typical residential Ductwork Cleaning in Loma Linda runs $350 – $650 for a full system, with commercial systems starting around $800.
Negative-Air Method with HEPA Filtration
We connect a Nikro negative-air machine to your duct system, creating suction that pulls loosened debris toward the vacuum while preventing it from escaping into your home. A HEPA filter captures particles down to 0.3 microns, which matters in Loma Linda when fine wildfire ash has coated your return ducts after a Santa Ana event.
Rotary Brush Agitation for Light Debris
For newer flexible ducting near the university, we use Rotobrush rotary brush systems that scrub the duct walls without the aggressive contact that would tear brittle galvanized steel. The brush head is sized to the duct diameter, and the technician controls speed and pressure manually.
Trusted Brands We Service in Loma Linda
We stock filters and components from Honeywell, Aprilaire, and Abatement Technologies for Loma Linda customers, which means faster turnaround when your system needs a MERV upgrade or media replacement after a heavy cleaning. Our crews carry common sizes on the van, and we can source less common dimensions within a day or two. We don’t make you wait for parts that should be standard inventory.
Common Air Duct Cleaning Problems We See in Loma Linda Homes
- Wildfire ash loading after Santa Ana events. After major Santa Ana wind events, technicians often find fine dust and ash from nearby wildfire zones coating the inside of return ducts in homes near the 10 freeway corridor, requiring specialized HEPA vacuuming that standard cleanings miss.
- Brittle galvanized steel in ranch-era homes. Much of Loma Linda’s housing consists of mid-century ranch-style homes built in the 1950s-70s, many with original galvanized steel ductwork that can accumulate decades of dust and require careful cleaning to avoid damage.
- Wood smoke infiltration from outbuilding stoves. Rural properties around Loma Linda with wood heat in detached shops or outbuildings often see smoke and ash migrate into the main house duct system through shared air handlers or poor isolation.
- Accelerated dust cycles on unpaved-road properties. Assuming a standard seasonal cleaning is enough on unpaved-road and open-land properties is a mistake. Rural Loma Linda lots load ducts with dust and pollen far faster than a suburban tract home, so the interval has to be shorter.

FAQs About Air Duct Cleaning in Loma Linda
Every 3 – 5 years for typical suburban homes, but every 2 – 3 years for rural Loma Linda properties on unpaved roads or with wood heat. The dust and pollen loading from open land, plus wood ash from outbuilding stoves, fills ducts faster than a filtered suburban tract. Call (361) 326-5060 and we’ll assess your specific property.
We show you before-and-after photos of your own ducts, taken with our video inspection camera. Loma Linda’s high concentration of medical professionals, many from Loma Linda University Health, means we regularly get asked for documentation of debris removal, and we provide it as standard practice on every job. No photos, no proof.
Honest full-system cleaning in Loma Linda costs $350 – $650 because it takes 3 – 4 hours with proper equipment and a two-person crew. The $99 offers typically cover one or two vents, then upsell aggressively once the technician is inside. We give one flat price per system in writing before work starts. That price does not move at the door.
Yes, and we recommend it. Treating an outbuilding, shop, or detached structure as “out of scope” leaves a lint pathway and ash load that keeps re-entering the house. We price detached structures separately and include them in the written estimate.
The 365-Day Done Right Promise covers it. If our work fails within a year, Hollis returns and makes it right at no charge, including a free second visit. The guarantee is backed in writing on every job, not negotiated after the fact.
