Lennox Air Duct Cleaning in Pasadena, CA | Hollis Air Duct Pasadena
We clean and seal Lennox ductwork across Pasadena, from Bungalow Heaven to the Arroyo Seco. Our crew works on Lennox Signature, Elite, and Merit systems every week, and we know the one thing that separates a good duct cleaning here from a wasted visit: Pasadena’s older homes were never built for modern Lennox air handlers. That mismatch shows up as dust, static pressure problems, and clogged coils. Call (626) 469-5477 for a written estimate before we touch anything.
We’re an independent Lennox service provider. That means we aren’t tethered to the manufacturer’s sales goals, and we don’t push parts you don’t need. Roy Castellanos, our owner, has been working on duct systems in Pasadena for over a decade. He learned the mechanical side of HVAC at Los Angeles Trade-Technical College, then spent years getting his hands dirty before building this crew. He’ll tell you straight what needs doing and what can wait. We also handle Lennox sales & service questions, but this page is about what happens inside your ducts.
Why Pasadena Residents Choose Us for Lennox Service
We show up inside the quoted window, price the job in writing before any work starts, and leave the site cleaner than we found it. Those aren’t adjectives. That’s the Garrison Code, the standard every Hollis technician follows. Background-checked, uniformed crew. Live person answers the phone at (626) 469-5477, day or night. No voicemail loop.
What that means for a Lennox owner in Pasadena: your system gets cleaned with Rotobrush rotary brush systems and Nikro negative-air machines, not hardware-store gear. When duct sealing is called for, we use commercial-grade mastic that matches or beats OEM spec. And before we recommend replacing a duct section, you’ll see video of exactly what we found inside. The duct work doesn’t lie, and neither do we.
Our 365-Day Done Right Promise covers every job in writing. If the work fails within a year, we come back at no charge, including a free second visit. That’s the standard we brought to Pasadena when we started serving this Pasadena service area, and it hasn’t moved.

Common Lennox Air Duct Cleaning Problems We Solve in Pasadena
- Clogged Lennox evaporator coils from Santa Ana dust. Fine particulate blows in off the foothills during wind season, and Pasadena’s dry Mediterranean climate means no rain to settle it. That dust cakes onto the coil, cutting cooling efficiency. We clean the coil as part of our duct service when it’s needed, no surprise upcharge.
- Leaking duct joints on high-static Lennox air handlers. Modern Lennox Signature and Elite blowers push more pressure than 1920s and 1930s ductwork was designed to handle. Joints that held fine for gravity heat start leaking once you add an air handler. We seal those leaks with mastic so the air you paid to condition actually reaches the room.
- Corroded Lennox heat exchanger surrounds in gravity-fed systems. Decades of Pasadena temperature swings, hot dry summers into cool damp winters, take a toll on galvanized steel. In older Craftsman homes, we often find the duct around the heat exchanger showing rust and pitting. We’ll show you before we recommend a fix.
- Torn flex duct pulling attic insulation into the Lennox blower. Unpermitted additions and quick remodels in Pasadena often left behind sagging, torn flex runs. Insulation and debris get sucked in and recirculated through your blower. We find them with video inspection and replace or seal as needed.
- Decades of dust in ducts sealed with 1920s cheesecloth and tar. This one is specific to Pasadena’s historic districts, and it’s not something a crew from outside the area will recognize. We know how to handle those old seals without wrecking the home’s original framing.
Lennox Service in Pasadena: What Local Conditions Mean for Your Equipment
In the Bungalow Heaven Landmark District, we regularly open ducts that were sealed with cheesecloth and tar back in the 1920s. That’s not a figure of speech. Homes around Mar Vista Avenue and the surrounding streets were built with a sealing method you simply don’t find in Glendale, Burbank, or anywhere else in the Valley. Those seals were never meant to hold the static pressure of a modern Lennox Elite air handler, and they eventually dry out, crack, and start leaking conditioned air into the crawlspace while pulling dust from there back into the house. The right fix isn’t to rip everything out. It’s careful removal of the old seal, a HEPA vacuum pass to capture decades of accumulated dust without throwing it into the living space, and a modern mastic seal that keeps the original duct where the historic character matters. A generic Lennox shop or a generic Pasadena handyman doesn’t know this. It’s why our video inspection matters before any work is priced.
Lennox Models & Products We Service in Pasadena
We work on the full Lennox residential line you’ll find in Pasadena homes: Signature Collection XC and XP series, Elite Series EL models, and Merit Series ML units. The ductwork doesn’t much care which series you have, but the air handler’s static pressure profile does. An XC25 on a 1940 duct run behaves differently than an ML14 on 1990s flex.
When a repair requires a component that must match exact Lennox spec, we order OEM. For duct sealing mastic, metal replacement sections, and insulation, we use commercial-grade aftermarket materials that equal or beat OEM performance for less money. We’ll tell you which is which and why. Our Pasadena stock keeps common mastic, sealants, and duct sections on hand so most jobs don’t wait on a shipment.

AfterLennox Service Pricing in Pasadena
Air Duct Cleaning in Pasadena runs roughly $390 to $690 for a typical single-family home, depending on the number of returns, the condition of the ducts, and whether we’re also cleaning the evaporator coil. Duct sealing typically adds $220 to $480 when it’s called for. Nobody should quote a per-vent price, and we don’t. You get one flat price per system in writing before we start, and that price does not move at the door. What affects cost here specifically: homes in the historic districts with cheesecloth-and-tar seals take longer because those seals require careful removal, not a hammer. Call (626) 469-5477 and we’ll give you an exact number after a look at your system. Estimates are free.

FAQs – Lennox Air Duct Cleaning in Pasadena
Santa Ana winds push fine dust and pollen into Pasadena homes from the foothills, and that dust settles inside your ducts faster than in coastal cities. For most Lennox owners here, every three to four years is realistic, versus the five to seven you sometimes hear quoted. If you’re near the Arroyo or any of the canyons, you’ll see more. Call (626) 469-5477 and we’ll tell you what your system actually shows.
Yes. We remove those old seals carefully, capture the dust with HEPA filtration, and replace the seal with modern mastic that holds up to a Lennox air handler’s pressure without disturbing the original framing or duct runs. We’ve done exactly this on Craftsman homes throughout Bungalow Heaven.
It can, especially if the coil hasn’t been cleaned in years. Santa Ana dust cakes onto the coil surface and insulates it, which reduces heat transfer. A clean coil runs cooler air at the same energy cost. We include coil inspection with our Dryer Vent Cleaning in Pasadena and recommend cleaning when it’s visibly fouled.
Usually worth keeping, with two checks. First, the static pressure of your new Lennox blower matters more than the duct’s age. Second, if the steel is rusted through at the seams or joints, sealing won’t hold. We video-inspect and give you a straight answer: seal if the metal is solid, replace only the sections that aren’t. No blanket recommendations.
They need a crew that knows both Lennox systems and Pasadena’s building stock. The dust here is fine and dry, and it behaves differently than humidity-laden dust. The ducts here are often original to early 20th century construction, and they need someone who knows when to preserve and when to replace. That’s the service we provide. Call (626) 469-5477 for a written estimate.
