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.
Lennox Air Duct Cleaning in Chicago, IL | CleanRun Air Duct Cleaning Chicago
We provide independent Lennox service across Chicago, and the one thing that makes our Lennox work here different is this: we’ve cleaned ductwork behind radiator-era retrofits in Bridgeport bungalows and greystone two-flats where the original duct installer never imagined a variable-speed blower would be drawing air through a closet chase built in 1923. Our crews carry OEM-compatible Lennox parts and the inspection tools to document what we find before we quote a written price. Call (708) 683-3974 for a free estimate.
Why Chicago Residents Choose Us for Lennox Service
Tomas Reyes, our owner, grew up in Queens and learned the trade at Apex Technical School in Long Island City. He’s spent the better part of two decades working through furnaces, air handlers, and return plenums across the Midwest. In Chicago, that means he’s personally run jobs in older two-flats near Logan Square where the original galvanized ductwork still carries sheet-metal screws from the Eisenhower era.
We know Lennox equipment because we’ve serviced it in the actual conditions it faces here. The long heating season from October through April, the Lake Michigan humidity cycles, the retrofit ductwork crammed into spaces never engineered for airflow - we’ve documented all of it. Our Lennox sales & service page covers our full equipment knowledge; this page is about what Chicago does to that equipment.
We’re an independent company. Not authorized by Lennox, not sponsored, not endorsed. We use OEM Lennox parts when they’re available and cost-effective, and for discontinued Merit or older Elite components we match quality aftermarket equivalents that meet original specs. Every job starts with a written price before any work begins, per Haven Standard Clause 1. Every duct run is photographed before and after. The 365-Day Done Right Promise is backed in writing, not just stated in marketing copy.
Tomas’s rule on every job: “Show the photo first. Talk second.” If there’s nothing to show the customer, there’s nothing to charge them for.
Common Lennox Air Duct Cleaning Problems We Solve in Chicago

- Variable-speed blower motor module failure in Merit and Elite air handlers. Chicago’s long heating season and humid summers keep these modules running at partial load for months. The electronics cook in basement closets with poor airflow, especially in bungalows where the closet was a coal bin conversion. We inspect the module housing, clean the heat sink fins, and check for voltage irregularities that accelerate capacitor degradation.
- Interior liner delamination in flexible duct runs. Lennox insulated flex duct used to connect hard duct to registers in bungalow retrofits sheds fiberglass into the airstream. That debris coats the blower wheel, evaporator coil, and secondary heat exchanger. Our video inspection catches this before cleaning starts, and we document the liner condition so owners see why the blower wheel needs separate cleaning.
- Mold growth in cased coils. Lake Michigan humidity cycles moisture through ductwork all summer. Lennox cased coils in older Merit and Elite systems become prime mold habitat when condensate pans can’t drain fully during shoulder seasons. We clean the coil housing, treat the pan, and photograph the drainage path to verify it’s clear.
- Secondary heat exchanger corrosion in high-efficiency furnaces. This accelerates when return ducts are undersized and leaky - standard in greystones and two-flats where original return chases were never sized for modern CFM. We measure static pressure across the heat exchanger and seal return leaks with mastic before cleaning, so the furnace isn’t fighting itself.
- Asbestos-containing duct wrap or mastic in pre-1980 retrofits. Our technicians assess for hazardous materials before any cleaning begins. If we find crumbling wrap on a supply trunk, we pause, have it tested, and proceed only after clearance. This is non-negotiable in Chicago’s bungalow belt.

AfterLennox Service in Chicago: What Local Conditions Mean for Your Equipment
Chicago’s roughly 80,000 Chicago-style bungalows were built with steam or hot-water radiator heat and later retrofitted with forced-air HVAC in the postwar decades. The ductwork was crammed into spaces never engineered for it. In Archer Heights, Marquette Park, and Bridgeport, we regularly encounter Lennox systems connected to runs routed through closet chases, low attic kneewall spaces, and basement drop ceilings that were never meant to carry air.
These non-standard configurations take far longer to clean than purpose-built forced-air homes in newer Sun Belt cities. The debris is compacted over 50-plus years. The access panels are sometimes nailed shut with trim from three renovations ago. And the duct wrap - that brittle, fiber-reinforced mastic from the 1950s or 1960s - can contain asbestos that must be assessed before a vacuum hose goes anywhere near it.
For Lennox owners, this matters because your variable-speed blower is trying to maintain constant CFM through ductwork with effective leakage area that would make a new-construction HVAC engineer wince. The module works harder, runs hotter, and fails sooner. Your cased coil sits in humid air that never fully drains because the condensate line was routed through a basement drop ceiling with no proper trap. We clean the system, but we also document the structural problems so you understand why the equipment behaves the way it does.
Our Chicago service area covers the full metro, but the bungalow belt is where our Lennox expertise gets tested hardest.
Lennox Models & Products We Service in Chicago

We service the full current and recently discontinued Lennox residential lineup. Merit Series: ML14XC1, ML13KC1, EL296V, EL280. Elite Series: EL16XC1, EL18XCV, SL280V, EL296V. Dave Lennox Signature Collection: SL25XPV, SL28XCV, SLP98V. Complete Heat systems: HM30, HM30V, HM30VP with matching air handlers.
Our parts approach is straightforward. OEM Lennox components when they’re available and the repair makes economic sense. For discontinued Merit blower modules or obsolete Elite control boards, we source aftermarket equivalents from manufacturers whose specs we verify independently. We tell owners plainly when a repair estimate crosses half the value of a 15-year-old system. Our Chicago warehouse stocks common Merit and Elite blower assemblies, ignition modules, and condensate pans for faster turnaround than ordering direct from Lennox.
Our equipment roster includes Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman - brands you can look up before we arrive.
Lennox Service Pricing in Chicago
Our Air Duct Cleaning in Chicago for full-system Lennox service typically runs $450-$750 for a single-family home, depending on duct run count, accessibility, and whether the system needs coil or blower wheel cleaning as separate tasks. Two-flats and three-flats with separate Lennox systems per unit start around $380 per system and scale with floor count. Video inspection is included in every estimate. Evaporator coil cleaning adds $180-$280 when accessible without refrigerant recovery.
What drives cost: non-standard retrofit ductwork takes longer to access and clean; asbestos assessment adds a testing fee we disclose upfront; and systems with severe liner delamination need blower wheel removal and separate cleaning. We deliver a written price before any work starts, every time, under Haven Standard Clause 1. No per-vent pricing. No coupon bait. Call (708) 683-3974 for an exact quote - estimates are free.

FAQs - Lennox Air Duct Cleaning in Chicago
We assess the wrap condition before touching anything. If the mastic or tape is intact and non-friable, we can often clean around it with negative-pressure extraction and sealed access points. If it’s crumbling, we pause and have it tested. We will not disturb asbestos-containing material. Call (708) 683-3974 and we’ll schedule an inspection.
Lake Michigan humidity keeps the cased coil and condensate pan wet through shoulder seasons when the system cycles less frequently. Stagnant water grows microbial film that the blower distributes on first startup. We clean the coil housing, treat the pan, and verify drainage - but we also check whether the return duct is pulling humid basement air past the coil when the system is off, which is common in retrofit closet installations.
Yes. We service HM30, HM30V, and HM30VP systems with matching air handlers. Parts availability is limited for the hydronic components, but the air-side ductwork cleans the same way. We document the system condition and advise when the air handler itself needs attention versus when duct cleaning alone will improve performance.
The original building was never designed for forced air. Return chases are often undersized, supply runs fight each other for static pressure, and access points may require cutting into finished surfaces we then seal properly. We measure system static pressure before and after cleaning to verify the Lennox blower isn’t overworking. The job takes longer than a comparable single-family installation. Call (708) 683-3974 for a written estimate specific to your building.
No. Routine maintenance including duct cleaning does not void Lennox equipment warranties. We are an independent service provider, not affiliated with Lennox, and we document our work so you have a record if warranty questions arise. Our 365-Day Done Right Promise covers our workmanship separately.
