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.

AfterLennox Air Duct Cleaning in Fresno, CA | Hollis Air Duct Cleaning
We provide independent Lennox air duct cleaning, coil cleaning, and flex duct repair across Fresno. Most Lennox systems we open up here have one thing in common: the attic heat has been working on the duct liner since the day it was installed. If your Lennox system is blowing dust or has lost airflow, call Hollis Air Duct Cleaning at (361) 326-5060 and we’ll give you a written price before anything gets touched.
Fresno’s cooling season runs from May through October, which means your Lennox air handler is cycling valley air through those ducts for six solid months. Dust, pollen, wildfire-smoke residue, and the occasional construction-debris surprise all settle in the trunk lines and branch runs. Our techs know exactly where Lennox systems collect that material and how to remove it without tearing up the flex. We also handle Lennox sales & service questions if you’re weighing a repair against replacement.
Why Fresno Residents Choose Us for Lennox Service
Roy Castellanos, our owner, spent years in the mechanical trades across Los Angeles County before starting Hollis Air Duct Cleaning. He learned duct work through the sheet metal and air conditioning program at Los Angeles Trade-Technical College, and he built this company on one rule: leave the system cleaner than you found it, no upsells, no guesswork. That carries through every Lennox job we take on in Fresno.
We treat Lennox systems as their own animal. Their cabinet fittings are tight, their flex duct specs are specific, and their blower assemblies collect fine valley dust differently than other brands. Our techs stock OEM-spec gaskets, mastic, and UL-181-listed flex so repairs happen in one visit. We’re an independent Lennox service provider, not manufacturer-authorized, which means we answer to you and the work, not a corporate warranty department. Every job gets a written price before we start. Every job is covered by our 365-Day Done Right Promise.
Common Lennox Air Duct Cleaning Problems We Solve in Fresno
These are the issues we see most often when we open up Lennox systems in Fresno homes:
- Cooked flex duct liners. Lennox flexible duct in Fresno attics, especially in the R-4 through R-8 range, gets baked by 140-160°F attic temps all summer. The mylar facing cracks and delaminates, and fiberglass particles start blowing through the registers. You’ll see fine gray dust on furniture within hours of the system running.
- Dust-loaded blower wheels. Lennox air handlers with PSC or variable-speed blower wheels collect a dense coating of valley dust and wildfire-smoke residue on the fins. The wheel gets out of balance, airflow across the coil drops, and the system runs longer to hit the same setpoint. A cleaning often restores airflow without replacing anything.
- Blocked evaporator coils. Top-connection Lennox evaporator coils in cased enclosures trap PM2.5 that slips past standard 1-inch filters. The coil partially blocks, which mimics a refrigerant issue and drives up head pressure when Fresno hits 105°F. Cleaning the coil fixes what looks like an expensive repair.
- Leaky return trunks. Lennox high-efficiency furnaces with secondary heat exchangers recirculate fine dust from leaky return trunks. That dust accelerates soot buildup on the secondary coil and quietly degrades combustion efficiency. Sealing the return and cleaning the secondary fixes it.
- Disconnected or sagging flex runs. Attic heat softens the duct supports and tape on older Lennox installs. Runs sag, kink, or separate at the takeoffs, and conditioned air dumps into the attic instead of the living space. We find this constantly in Fresno’s 1980s-2000s stucco tracts.
Lennox Service in Fresno: What Local Conditions Mean for Your Equipment
Here’s the thing about Fresno that most generic duct cleaning pages won’t tell you. This city sits in the San Joaquin Valley, which routinely fails federal PM2.5 and ozone standards. Your Lennox system is pulling that particulate into the return, pushing it across the coil, and blowing it through the supply runs for half the year. No coastal California city has that combination. And when you add a six-month cooling run to the equation, the ducts never get a break long enough for the accumulated material to settle out. It just keeps recirculating.
In a 1990s stucco subdivision near Bullard and West in north Fresno, we cleaned a Lennox SL280V furnace and matching air handler where the homeowner kept finding gray dust on the furniture within hours of the system kicking on. Video inspection showed the mylar liner on two supply flex runs had cracked and was shedding into the airstream. We replaced the damaged sections with OEM-spec R-8 flex, mastic-sealed the takeoffs, and cleaned the blower wheel. The dust complaints stopped immediately. That’s the Fresno failure mode that techs in cooler markets rarely see. our Dryer Vent Cleaning in Fresno - plus clean ducts, straight answers - that’s the whole job.
Lennox Models & Products We Service in Fresno
We work on the full Lennox residential lineup. The Merit Series, including the 14ACX and ML14XC1 air conditioners with matching indoor coils, shows up all over Fresno’s post-WWII tract homes. The Elite Series, like the EL16XC1 and XC21 variable-speed systems, sits in a lot of the 1980s-2000s stucco subdivisions north and northeast of downtown. The Dave Lennox Signature Collection, including the SL28XCV and SL280V furnaces and air handlers, is common in newer construction. We also clean and service Lennox Healthy Climate media cabinets and filtration accessories paired with these systems.
On the parts side, we use OEM-spec flexible duct, mastic, and gaskets for Lennox repairs because the factory tolerances on their cabinet fittings are tight. When an aftermarket UL-181-listed component offers better heat resistance in a Fresno attic, we’ll explain why and use it instead. We stock the common sizes locally so most Lennox jobs wrap up in one visit.
Lennox Service Pricing in Fresno
Lennox air duct cleaning in Fresno typically runs $350 to $600 for a full system, depending on the number of supply runs, the number of returns, and how much material has built up. Flex duct repair or replacement usually adds $150 to $300 per section depending on the run length and access. Evaporator coil cleaning typically runs $200 to $400 as a standalone service or less when paired with a full duct cleaning. These are whole-system prices: one flat number, written down, before we touch anything. No per-vent pricing, no surprises at the door.
The variables that move the price are the number of registers, the age and condition of the flex, and whether the blower wheel and coil need a deep clean while we’re in there. Every estimate includes a video inspection of the duct interior so you can see what we found and why we’re recommending what we’re recommending. For an exact quote on your Lennox system, call (361) 326-5060. Estimates are free.

FAQs – Lennox Air Duct Cleaning in Fresno
Yes. Fresno attics routinely hit 140-160°F in July and August, which cooks the mylar lining on Lennox flexible duct until it cracks, delaminates, and starts shedding fiberglass into the airstream. Coastal cities with milder attic temperatures rarely see this failure mode. In Fresno, it’s one of the most common things we find. Call (361) 326-5060 for a free video inspection of your duct interior.
Yes, with a caveat. Cleaning the coil removes the particulate that’s already trapped there, which restores airflow and lets the system do its job. But keeping future PM2.5 out requires better filtration. A Lennox Healthy Climate media cabinet with a MERV 11 or higher filter will capture far more valley particulate than a standard 1-inch filter. We can clean the coil and explain your filtration options in the same visit. Call (361) 326-5060 for a written quote.
If the air handler is 18 years old and the duct system is already failing, we’ll tell you straight: sealing and cleaning may be throwing money at a unit that’s near end of life. Lennox air handlers can run past 15 years, but once the blower motor, coil, and ducts all need work, replacement often costs less in the long run. We’ll show you the numbers both ways and let you decide. No pressure either direction.
In Fresno, every 3 to 5 years for most homes, and more often if you live near an orchard, a construction zone, or a busy road. The valley particulate load and the six-month cooling run mean your ducts accumulate material faster than systems in milder climates. If you can’t remember the last cleaning, it’s overdue. Call (361) 326-5060 and we’ll inspect first so you only pay for what the ducts actually need.
We use OEM-spec flexible duct, mastic, and gaskets sized to Lennox’s factory tolerances. Lennox doesn’t manufacture all of its own duct components, so the aftermarket equivalents we use are UL-181-listed and often offer better heat resistance for Fresno attics. We’ll show you exactly what we’re installing and why before any repair happens.
