Our Air Duct Cleaning Services in North Hills
Residential Duct Cleaning
North Hills homes were built for a different era of air quality. The single-family ranch tracts along Nordhoff Street and Plummer Street still run original sheet-metal trunk lines with fiberglass flex duct branches that have never been properly cleaned. Our residential service pulls debris from every reachable run using Rotobrush agitation and Nikro HEPA vacuum collection. We focus on the full system, not just the vents you can see.
Commercial Duct Cleaning
Small commercial buildings along the Roscoe-Sepulveda corridor - medical offices, retail suites, light industrial - face the same valley particulate load as homes, but with higher occupancy and more stringent air turnover requirements. We clean supply and return systems in commercial properties with minimal disruption to operations. Most commercial jobs in North Hills are scheduled early morning or Saturday to avoid business hours.
Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces. In North Hills, these lines often originate in attics that hit 140°F in July, baking accumulated debris into the duct walls. We clean every supply register and trunk line, paying special attention to the flex-to-metal connections that cracked during the 1994 earthquake and were never properly resealed.
Return Duct Cleaning
Return ducts pull air back to your HVAC unit for reconditioning. These run through wall cavities and underfloor spaces in North Hills’s slab and raised-foundation homes, making them the hardest to access and the most neglected. Our return duct cleaning service uses camera-guided tools to navigate these tight runs and extract the demolition dust and debris that settled there decades ago.
Full System Cleaning
This is our most thorough service for North Hills homes. We clean supply ducts, return ducts, trunk lines, plenums, and the HVAC cabinet itself as a single integrated system. Full system cleaning is what we recommend for any home with post-quake patchwork ductwork, because partial cleaning leaves debris that immediately recontaminates the cleaned sections. One honest price covers the complete job.
Video Inspection
Every full system cleaning includes video inspection before and after. We use a camera-equipped scope to document the condition of your duct interior, identify earthquake-damaged joints, and show you the results of our work. The video file is yours to keep. In North Hills, these inspections frequently reveal flex duct that was rerouted during 1994-1996 repairs but never cleaned - a finding that changes how homeowners understand their own air quality.

Trusted Brands We Service in North Hills
We clean and maintain duct systems connected to all major HVAC brands, and we carry replacement components from Abatement Technologies, Rotobrush, and Nikro for repairs that can’t wait. For air quality upgrades, we install Aprilaire and Honeywell filtration and sanitizing equipment sized to the specific load factors of San Fernando Valley homes. Our North Hills warehouse stocks flex duct in the diameters common to post-war tract construction, so replacement of damaged sections happens same-day rather than next-week. When a homeowner near Roscoe and Sepulveda needs a part, we don’t order it - we drive it.
Common Air Duct Cleaning Problems We See in North Hills Homes
- Earthquake-damaged duct joints circulating hidden debris. The 1994 Northridge earthquake epicenter sat roughly two miles from North Hills, and the structural shock cracked or fully disconnected duct connections in attics and underfloor cavities. Homes that received structural repairs afterward often had their ductwork overlooked, leaving systems that have silently circulated drywall dust and debris through loose joints for thirty years.
- Low-slope rooflines baking flex duct to failure. North Hills’s concentration of ranch-style homes with low-slope rooflines traps extreme heat in attics. Fiberglass flex duct that was patched rather than replaced after 1994 embrittles in these conditions, cracking at stress points and creating hidden debris accumulation zones that reduce airflow and force your HVAC to work harder.
- Valley-trapped particulates loading HVAC intakes. Sitting deep in the landlocked San Fernando Valley and ringed by mountain ranges, North Hills traps vehicle exhaust, construction dust, and wildfire smoke far more than coastal LA communities. HVAC intakes here load up with particulates at a measurably higher rate, accelerating debris buildup inside duct systems that were never designed for this air quality load.
- Compacted demolition dust from post-quake renovations. On a ranch-style home near Roscoe and Sepulveda, our crew used a Rotobrush to clean original sheet-metal trunk lines and found flex duct rerouted after the 1994 quake still packed with demolition drywall dust. The homeowner had assumed the system was updated; we cleared 30 years of particulate and provided a video inspection to document the hidden residue. This is not unusual in the 91343 ZIP.

FAQs - Air Duct Cleaning in North Hills
Yes - in our experience, very often. The 1994 Northridge earthquake damaged duct connections throughout North Hills, and many homes received structural repairs that never included duct cleaning or replacement. We’ve found demolition drywall dust from 1994-1996 renovations still packed inside flex duct runs that were simply rerouted and left. Our video inspection will show you exactly what’s in there. Call (855) 401-6006 to schedule - estimates are free.
Every 3-5 years for most North Hills homes, and every 2-3 years if you live near major thoroughfares like Sepulveda or Roscoe where vehicle exhaust concentration is highest. Wildfire seasons in the San Fernando Valley have grown longer and more intense, and that smoke loads your HVAC intake filters and ductwork faster than coastal climates. Homes with post-quake patchwork ductwork should start with a full system cleaning and video inspection to establish a baseline. Call (855) 401-6006 and we’ll recommend a schedule based on your specific home.
It can help significantly if your symptoms worsen when the HVAC runs. We frequently hear from North Hills homeowners that sneezing, congestion, and eye irritation spike within minutes of the system cycling - that’s a strong indicator your ducts are circulating particulate rather than just moving air. Our HEPA-contained cleaning removes the accumulated debris, and we can recommend Aprilaire or Honeywell filtration upgrades sized to your system. We don’t promise medical outcomes, but we do document the debris we remove. Call (855) 401-6006 for a free estimate.
Yes - these are precisely the homes we specialize in. The post-war ranch tracts near the epicenter, including large sections of the 91343 ZIP, contain original sheet-metal trunk lines and flex duct that have never been properly inspected since 1994. Our technicians carry the fittings and diameters common to this era of construction, and our camera equipment navigates the tight attic spaces typical of these homes. We’ve cleaned hundreds of them. Call (855) 401-6006 to add yours to that number.
We use professional-grade Rotobrush brush-and-vacuum systems for agitation and debris removal, Nikro HEPA-contained vacuums for collection, and Abatement Technologies camera equipment for inspection. These are the same brands serious HVAC contractors specify, not discount rental tools. For air quality upgrades, we install Aprilaire and Honeywell filtration and sanitizing systems. Every piece of equipment is maintained to manufacturer specification and operated by trained technicians. Call (855) 401-6006 with questions about our process.
