Airport, Industry and Post-War Ductwork
Van Nuys carries an ambient particulate load that is industrial rather than natural, and it comes from three sources that no other neighbourhood we serve has stacked together in the same way. Van Nuys Airport sits in the middle of the residential grid and is one of the busiest general aviation airports in the world, with circuit and departure patterns passing directly over houses on every side. Piston aircraft in particular emit at low altitude right over residential roofs.
The Sherman Way industrial corridor runs east-west through the neighbourhood with light manufacturing, metalworking, autobody and distribution operations along it. And Interstate 405 and US 101 bracket the area, adding traffic particulate on both flanks. The combined result is a fine, dry, mineral and combustion-heavy dust load that is quite distinct from the pollen-driven loading we find in Los Feliz or the organic canyon debris in Studio City.
That matters because of how fine dry particulate behaves in a duct. It does not settle near the register the way heavier organic debris does; it stays in suspension, travels the full length of the run, and reaches the evaporator coil. On a Van Nuys system the typical finding is a uniform grey film throughout the ductwork and a coil that is more loaded than the ducts are — which is precisely the pattern a cheap duct-only clean fails to address.
The housing then makes it harder to reach. Van Nuys was built fast between 1945 and 1960 for volume, and the ducting reflects that: a central air handler, long attic trunk lines run as directly as the framing allowed, and ceiling or high-wall registers. Wide ducts with slow-moving air, in an attic that hits well over a hundred degrees in summer, carrying seventy-five years of accumulation. Call (818) 536-7759.
What a Full HVAC Cleaning Includes in Van Nuys
There is a real difference between duct cleaning and HVAC system cleaning, and the difference is where most of the airflow is actually being lost. This is what the full-system service covers.
Supply and Return Ducts, Cleaned the Full Run
Every supply branch and every return is cleaned end to end with rotating brush and air-whip tools sized to the duct, not just vacuumed at the register. The difference matters: vacuuming a register pulls the dust you can see and leaves the loading further down the run, which then migrates back out within weeks. Return ducts are usually the dirtier side and the more often skipped, because they are harder to reach. We clean both sides and photograph each trunk line before and after so you can see the state it was actually in.
Evaporator Coil and Air Handler
This is the part most duct-cleaning quotes leave out, and it is frequently where the real restriction is. The evaporator coil sits in the air handler and its fins are closely spaced by design, so it acts as a filter whether you want it to or not. A fouled coil cuts airflow across the whole system, raises running cost, and in humid conditions becomes a damp surface where biological growth establishes. Cleaning it properly means accessing the cabinet and treating the coil, not spraying through a register and hoping.
Blower Wheel, Housing and Cabinet
The blower wheel is a squirrel-cage fan, and dust builds up on the leading edge of each blade. As it accumulates the blade profile changes, the fan moves less air for the same power draw, and the imbalance eventually tells on the motor bearings. A heavily loaded blower wheel is one of the most common reasons a system that was adequate now struggles, and cleaning it restores airflow immediately and measurably. The housing and the interior of the cabinet are cleaned at the same time, because leaving them loaded just re-contaminates the wheel.
Registers, Grilles and Boots
Every supply register and return grille is removed, washed and refitted, and the boot — the sheet metal box behind the register where the duct meets the room — is cleaned out. Boots collect the heaviest debris in the whole system because they are the low point of each run and because anything dropped through a floor register ends up there. We find a remarkable amount in them. Refitting a clean register to a loaded boot is one of the clearest signs of a system that was cleaned for appearance rather than function.
Honest Pricing on a Straightforward System
Van Nuys houses are consistent, which makes this one of the easier places for us to quote accurately and one of the harder places for anyone to justify an inflated price. A standard single-zone post-war tract house is a $299 full-system job in the large majority of cases, and we will tell you on the phone if we think yours is likely to be different and why. The $89 whole-house duct cleaning advertisements you see are not a real price for this work; they are a door-opener, and the number goes up substantially once the technician is inside.
What genuinely does change the price here is the air handler location and the number of zones. An air handler in a tight attic with poor access takes longer than one in a hallway closet. A house that has had a second system added for a converted garage or an addition is two systems and we price it as such. Neither of those is a surprise we spring on you — tell us what you have when you call and the quote will hold.
The one thing we find in Van Nuys more than elsewhere is rodent activity in attic ductwork. Open attics, older construction and a lot of adjacent commercial and industrial space make for rodent pressure, and droppings and nesting material in a supply duct is a genuine health matter rather than a cleanliness one. Where we find it we photograph it, clean and then sanitize with an EPA-registered treatment from $99, and we tell you where the entry point is so it can be closed rather than recurring.
Signs Your Van Nuys HVAC System Needs Cleaning
Most of these are gradual, which is why they get normalised. If two or more apply, the system is almost certainly carrying enough loading to be costing you in airflow.
Our Process — NADCA ACR Standard
The NADCA ACR standard is what separates a system that has been cleaned from one that has been disturbed. Every job follows these five stages.
System assessment and duct inspection
We identify the system type, locate every trunk and branch, and camera-inspect inside the ductwork before touching anything. You see what is in there first, which also establishes the scope honestly rather than after the fact.
Negative pressure containment
A HEPA-filtered negative air machine is connected to the trunk line so the whole system is held under negative pressure during cleaning. This is the part that distinguishes NADCA-standard work: dislodged debris goes into the machine rather than into the rooms.
Mechanical agitation of every run
Rotating brushes and compressed-air whips sized to each duct dislodge the adhered loading that a vacuum alone will not lift. Supply and return, every branch, the full length of the run.
Air handler, coil and blower
The cabinet is opened, the blower wheel and housing cleaned, and the evaporator coil treated. This is where airflow is most often being lost and it is done as part of the full-system service.
Registers, verification and photos
Registers and grilles washed and refitted, boots cleared, then airflow verified at each register and the before-and-after photo set handed over. The filter is replaced if you have one on site.
