North Hills sits deep in the landlocked San Fernando Valley, where the Santa Susana and San Gabriel ranges trap vehicle exhaust, construction dust, and wildfire smoke at measurably higher concentrations than coastal LA. Your HVAC works harder here and loads up faster. The housing stock compounds the problem: thousands of 1950s-1970s ranch-style tract homes with original sheet-metal trunk lines and aging fiberglass flex duct, many patched rather than replaced after the 1994 Northridge earthquake. Our crews know these systems. We dispatch from our Los Angeles office and serve North Hills locally.

Why North Hills Homes Are Different

The epicenter of the 1994 Northridge earthquake sat roughly two miles from the heart of North Hills, subjecting post-war tract homes to severe structural shock. Duct connections in attics and underfloor cavities cracked or fully disconnected. Even 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 on these ranch homes bake attic ductwork in extreme heat, rarely accessed and rarely inspected. Summer temperatures along the Roscoe-Sepulveda corridor regularly surpass 100°F, driving air conditioners near-continuously for months and accelerating debris buildup. Technicians working the 91343 ZIP routinely pull attic panels and find flex duct rerouted or hastily patched during 1994-1996 renovations but never cleaned - compacted demolition drywall dust still present inside runs, invisible to homeowners who assumed their system was “updated.”

Air Duct Cleaning in North Hills

Our Air Duct Cleaning service handles the full system: supply and return trunk lines, branch ducts, and registers. Most full residential jobs in North Hills fall between $280 and $580, with a typical ranch-style home of 10-15 registers landing in the $340-$450 range. We inspect with a camera first, show you the footage, and lock the price before we start.

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.

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.

My 1950s North Hills home had ductwork patched after the 1994 earthquake. Could there still be drywall dust inside?

Yes - in our experience, very often. Contractors prioritized structural repairs; ductwork was rarely cleaned and often only patched where visibly broken. 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.

Dryer Vent Cleaning in North Hills

Dryer vent cleaning in North Hills typically runs $149-$289 for a standard single-family home and is usually completed in one visit. The combination of post-earthquake flex-duct patching and extreme summer heat causes vent connections to separate or collapse, trapping lint that previous repairs overlooked. Our Dryer Vent Cleaning starts with a camera inspection every time.

Dryer Vent Inspection & Cleaning

Every job begins with a camera run from your dryer’s back panel to the exterior cap. We document what we find, show you the footage, and only then recommend cleaning or repair. On a recent job near the Roscoe-Sepulveda corridor, our crew found an original fiberglass flex duct hastily patched after 1994; the patch had separated, and the vent was packed with drywall dust and lint. We cleared the entire run with Rotobrush equipment and installed a new galvanized vent cap with bird guard. Basic vent cleaning for accessible, single-story runs runs $149-$189, while multi-story or extended runs requiring additional access fall in the $189-$249 range.

How does North Hills’ heat affect dryer vent cleaning frequency?

North Hills homeowners should have dryer vents inspected every 12-18 months instead of the standard 2-year interval for coastal climates. Summer temperatures regularly surpass 100°F along the Roscoe-Sepulveda corridor, and attic temperatures can reach 140°F, accelerating fiberglass duct deterioration and causing separated joints to accumulate lint faster. Call (855) 401-6006 and we’ll put you on a schedule that makes sense.

HVAC Cleaning in North Hills

HVAC cleaning in North Hills typically runs $180-$650 depending on which components need attention, and most jobs are completed in a single visit. If your system hasn’t been opened since the 1994 earthquake repairs, the blower wheel and evaporator coil may be circulating decades of accumulated debris. Our HVAC Cleaning addresses the components that actually move and condition your air.

Evaporator Coil & Blower Cleaning

The evaporator coil does the actual work of cooling your home. In North Hills, where summer temperatures push past 100°F, that coil runs near-continuously for months. A dirty coil can’t transfer heat efficiently, so your system runs longer and still leaves rooms warm. Most evaporator coil cleanings run $180-$320. The blower motor and wheel push conditioned air through every room; when blades load up with dust, airflow drops and the motor strains. A typical blower cleaning costs $200-$350. In homes with original sheet-metal trunk lines, blower contamination is often worse because loose duct connections upstream allow unfiltered attic air to enter the return side.

My North Hills home was built in the 1950s - do I need HVAC cleaning even if I replaced the furnace?

Yes. The furnace is just one component; your ductwork, evaporator coil, and blower may be original or patched with post-quake flex duct that has never been cleaned. On a ranch-style property near Roscoe and Sepulveda, we opened a crawlspace to find original trunk lines paired with flex duct rerouted in 1995 - the homeowner had assumed the system was fine, but we extracted compacted drywall dust from the 1994 repairs still circulating inside.

Duct Repair & Sealing in North Hills

Duct repair and sealing in North Hills typically costs $280-$650 for most residential jobs, with larger acreage properties running $450-$900. Our crew carries enough flex duct, metal trunk material, and mastic sealant to complete most repairs in a single visit. If your ranch-style home is losing airflow, pulling dust from the attic, or running the AC nonstop, the problem is often leaky joints from 1994-era damage. Our Duct Repair & Sealing fixes what others missed.

Duct Sealing & Flex Duct Repair

Leaky duct joints in North Hills’s 1950s-1970s ranch homes waste 20-30% of conditioned air into attics and crawl spaces. We regularly find trunk lines never properly sealed after the ’94 quake, with gaps wide enough to slide a hand through. We seal with mastic compound and reinforced mesh, not tape that dries and fails under attic heat. A typical duct sealing job runs $280-$450 for a single system. Flex duct repair or replacement per run falls in the $320-$580 range. On acreage properties, detached workshops create special problems: heavy-duty garage door springs and opener brackets often shift against overhead flex runs, splitting the outer liner.

Does your crew bring enough material for one-trip service to large-lot North Hills properties?

Yes. Our trucks carry 25-foot rolls of flex duct, sheet metal trunk sections, mastic compound, insulation, and connection hardware sized for residential systems. For acreage properties off Parthenia and Plummer with detached workshops, we confirm the scope by phone and load extra material specifically for that job. Most large-lot repairs finish in one extended visit. Call (855) 401-6006 to schedule, and we’ll confirm your property details so nothing’s wasted.

Air Quality & Sanitizing in North Hills

If you’re noticing persistent dust on your North Hills registers, musty odors when the AC kicks on, or worsening allergies inside your own home, professional air quality and sanitizing services typically run $250-$650 for duct cleaning with sanitizing, and most jobs are completed in a single afternoon. Our Air Quality & Sanitizing targets what’s living in your system, not just what’s visible.

Mold Treatment & Bacteria Sanitizing

North Hills’s combination of aging fiberglass flex duct and extreme attic heat creates conditions for mold colonization. When low-slope rooflines trap summer temperatures above 140°F, then cool rapidly when AC cycles on, condensation forms inside duct runs - especially at unsealed joints from 1994-era repairs. A typical mold treatment runs $400-$900 depending on contamination extent. Bacteria sanitizing addresses organic buildup: skin cells, pet dander, pollen, and leftover demolition debris from 1994 quake repairs that provides a substrate for bacterial growth. Most bacteria sanitizing jobs fall between $300-$600 when paired with duct cleaning. We apply hospital-grade sanitizer through the full duct network with before-and-after camera documentation.

Does the 1994 Northridge earthquake affect my home’s air quality today?

Yes, if your home was repaired after the 1994 quake and the ductwork was not cleaned, you may still have demolition drywall dust cycling through your system. Our technicians often see a fine gray dust residue on the inside of supply registers, especially in homes built before 1975. We can inspect with a camera to confirm if legacy drywall dust is present. Call (855) 401-6006 - estimates are free.
