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.

AfterAir Duct Cleaning in Lisle, IL
HVAC cleaning in Lisle typically runs $320-$580 for a full system, and most jobs are scheduled within a week during peak season. We dispatch crews from our Chicago office to Lisle daily, equipped with Rotobrush and Nikro systems to handle the 1970s-80s ductwork common in DuPage County’s I-88 corridor subdivisions. Call (331) 236-5490 for a written estimate before any work starts.
Why Lisle Homes Are Different
Lisle’s housing stock is overwhelmingly ranch and two-story Colonial homes built between the mid-1970s and late 1980s, when DuPage County expanded along the I-88 corridor. These homes carry 40-50-year-old stamped-metal or early flex-duct systems that were never designed for today’s continuous-operation furnaces and central air. Furnaces have been swapped out once or twice, but the duct runs behind walls and in basements rarely get inspected or resealed during those replacements.
The Morton Arboretum’s 1,700-acre canopy makes Lisle unique. Its multi-species pollen loads and late-May cottonwood seed dispersal blanket neighborhoods along Maple Avenue, Warrenville Road, and the streets off 4100 Route 53. Return-air vents in these homes pull that material straight into ductwork, and standard filter schedules cannot keep up. June service calls in western Lisle near the Arboretum almost always reveal return-duct interiors packed with cottony poplar seed material, even with recent filter changes.
Climate compounds the problem. December through February, continuous furnace operation blows air across decades-old unsealed joints, redistributing settled debris. Summers bring muggy conditions with dew points in the upper 60s°F, creating condensation inside degraded flex-duct insulation that fosters mold growth.
Our Main Lisle Services
These are the three services Lisle homeowners call about most, each with its own detailed page:
Air Duct Cleaning in Lisle
We clean the full duct network, from return plenum (the sheet-metal box that collects air before it reaches the furnace) to every supply register, using negative-pressure extraction that pulls debris toward the vacuum rather than pushing it into your home. In Lisle, we regularly find Arboretum-related biological material layered with construction-era dust in the original stamped-metal trunk lines. Every run is photographed before and after.

Dryer Vent Cleaning in Lisle
Dryer vent blockages are a leading cause of house fires, and Lisle’s mature trees contribute lint-trapping debris at exterior terminations. We remove buildup from the appliance connection through the roof or wall cap, then verify airflow with a meter. The job concludes with before-and-after photos of the vent interior.

Duct Repair & Sealing in Lisle
Forty-year-old duct joints in Lisle homes have dried tape, separated seams, and rusted hangers that leak conditioned air into attics and crawl spaces. We seal accessible joints with mastic and mechanical fasteners, then pressure-test the system to verify results. Repair scope is photographed and written into the job record.

BeforeAfterHVAC Cleaning in Lisle
HVAC cleaning in Lisle addresses the components your ductwork connects to: the evaporator coil, blower assembly, condenser, air handler, and heat exchanger. These units collect the same Arboretum pollen and cottonwood seed that clogs ducts, plus the dust that bypasses aging filters in 1970s-80s systems. Without periodic cleaning, that buildup restricts airflow, forces longer run times, and recirculates debris every time the system cycles. Our crews use Rotobrush and Nikro equipment to clean each component without disassembling what does not need service. HVAC Cleaning covers our full methodology for homeowners researching before they call.
Evaporator Coil Cleaning
Signs you need it
Ice forming on refrigerant lines, weak airflow from vents, or cooling that cannot keep up during Lisle’s humid July afternoons.
What it costs in Lisle
Evaporator coil cleaning typically runs $180-$340 depending on accessibility and buildup severity.
How we do it
We apply foaming cleaner that breaks down biological growth and dust, then rinse with low-pressure water capture so nothing drains into the furnace below.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven heating between rooms, or a motor that runs hot to the touch.
What it costs in Lisle
Blower assembly cleaning ranges from $160-$290 based on motor type and housing complexity.
How we do it
The blower wheel and housing are removed, brushed and vacuumed, then rebalanced before reinstall to prevent future bearing wear.
What HVAC Cleaning Costs in Lisle
| Item | Typical range in Lisle |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower assembly cleaning | $160-$290 |
| Full HVAC system cleaning (coil + blower + housing) | $320-$580 |
How do I know my HVAC components are actually dirty?
We photograph every component before touching it, and you receive those images as part of the standard job record. If the evaporator coil shows clean aluminum fins, we will tell you cleaning is not needed rather than charge for unnecessary work.
Can HVAC cleaning fix my high summer electric bills?
It can help if restricted airflow is forcing longer run times, but we will inspect first and report whether duct leakage or insulation gaps are the larger factor. Call (331) 236-5490 for a written assessment.
Air Quality & Sanitizing in Lisle
Air quality and sanitizing in Lisle targets the biological load that Arboretum pollen and humid summers introduce into 40-year-old duct systems. Condensation inside degraded flex-duct insulation creates conditions for mold growth that standard duct cleaning alone cannot address. We apply EPA-registered treatments and install physical barriers where appropriate, with every step documented in the photo record you receive. Air Quality & Sanitizing details our full protocol.
Mold Treatment
Signs you need it
Musty odor when the system first cycles, visible spotting on vent registers, or aggravated allergies that worsen when home.
What it costs in Lisle
Mold treatment for accessible duct runs ranges from $280-$450 depending on linear footage and treatment depth required.
How we do it
We apply an EPA-registered biocide to affected surfaces, allow proper dwell time, then extract residue with negative-pressure equipment and photograph verification.
UV Light Installation
Signs you need it
Recurring mold despite cleaning, or a system located in Lisle’s damp basement or crawl space where humidity stays elevated.
What it costs in Lisle
UV-C lamp installation runs $340-$520 including the fixture, bulb, and electrical connection to the air handler.
How we do it
A Honeywell or Aprilaire UV fixture is mounted inside the supply plenum to irradiate passing air and coil surfaces continuously, with annual bulb replacement scheduled.
What Air Quality & Sanitizing Costs in Lisle
| Item | Typical range in Lisle |
|---|---|
| Mold treatment (duct runs) | $280-$450 |
| UV-C lamp installation | $340-$520 |
| Combined air quality package (treatment + UV) | $520-$820 |
Is UV light actually effective, or just an upsell?
UV-C works when properly positioned in the air stream and maintained with annual bulb changes; it does not replace filtration or cleaning. We install only where the geometry allows adequate exposure time, and we will decline the job if your system layout cannot support effective placement.
Will mold treatment damage my old flex ducts?
We adjust application pressure and dwell time for 1970s-80s flex-duct material, and we photograph the interior first to identify degraded sections that should be repaired before any treatment proceeds. Call (331) 236-5490 for a written scope.
Brands We Service in Lisle

- Devon A."The dryer vent was almost completely blocked with lint. They showed me the photograph and I understood immediately why the dryer had been running twice."
- Lucia M.
