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 Deerfield, IL | CleanRun Air Duct Cleaning Northbrook
We provide independent Lennox service throughout Deerfield, not as an authorized dealer but as a crew that cleans and repairs these systems every week. The one thing that makes our Lennox work here different is this: Deerfield homes were built during an era of heavy renovation, and we’ve learned to trace the duct damage that kitchen gut-jobs and additions leave behind in Lennox blower wheels, return plenums, and coil cabinets. Call Deerfield service area at (224) 351-9772 for a written estimate before any work starts.
Why Deerfield Residents Choose Us for Lennox Service
Tomas Reyes, our owner, grew up in the Bronx and built his technical foundation at Apex Technical School in Queens before spending the better part of two decades working inside residential HVAC duct systems across northeastern Illinois. He and our crew have logged steady work throughout the area, including homes near older Deerfield neighborhoods where the ductwork hasn’t seen a brush since the original construction, which is why homeowners call us for our Air Duct Cleaning in Deerfield. Tomas still shows customers a camera photo of what’s inside the plenum before quoting a single dollar figure. The camera doesn’t negotiate - it just shows you what’s there.
We know Lennox equipment specifically, not generically. We’ve cleaned enough Lennox EL296V variable-speed furnaces and SL280V Signature systems in Deerfield split-levels to recognize the exact cabinet configurations, coil access angles, and blower deck designs that show up in this market. We stock OEM-equivalent blower modules, limit switches, and coil panels for fast turnaround, and we work under the H.A.V.E.N. Standard with background-checked, uniformed technicians. Every job gets a written price before work begins, Haven Standard Clause 1, and a Documented Photo Record of every duct run when we leave. That’s been our practice since 2013.
Common Lennox Air Duct Cleaning Problems We Solve in Deerfield
- High-limit faults on EL296V and SL280V furnaces after kitchen renovations. Lennox variable-speed blower motors pull hard when return static pressure climbs. In Deerfield, where kitchen gut-renovations from the 1990s and 2000s packed drywall dust into return plenums, that restricted airflow overheats the motor module and trips the limit switch. We clean the return, pull the blower wheel, and verify the fault clears.
- Mold and mildew at cabinet seams in Skokie River humidity. Deerfield’s location near the Skokie River corridor keeps basement mechanical rooms damp well into spring. Lennox painted or powder-coated cabinet doors hide rust and mold at the seams. A filter change won’t reach the interior metal. We inspect with a borescope and clean with negative-pressure extraction.
- Compressor overwork from debris-clogged evaporator coils. Lennox evaporator coils in upflow and horizontal applications collect construction debris on the downstream face. In Deerfield homes with flex-duct runs disconnected during additions, airflow drops and the compressor runs hot all summer. We clean the coil face and reconnect or seal the duct runs.
- Stress cracks in older G-series heat exchangers. Late-1970s Deerfield builds still run Lennox G-series furnaces. Restricted return air from a clogged blower wheel and dirty secondary heat exchanger creates heat stress. We clean the full assembly and tell you plainly if the heat exchanger is beyond safe operation.
- White dust at registers from disconnected flex runs. Deerfield’s high rate of upscale additions left flex-duct runs disconnected behind finished basement ceilings. The Lennox system pressurizes the crawl space or wall cavity instead of the bedroom, and construction debris recirculates. Our video inspection finds the break; we reconnect with mastic and metal connectors rated for Lennox temperature swings.
BeforeAfterLennox Service in Deerfield: What Local Conditions Mean for Your Equipment
Deerfield’s mid-century split-levels and colonials along the Skokie River corridor often have return-air plenums still holding drywall dust from 1990s and 2000s kitchen gut-renovations, and that trapped particulate is the first thing our camera hits when we inspect a Lennox system in these homes. The homeowner upgraded the countertops, the cabinets, the flooring - everything visible - but the original sheet-metal returns absorbed and held all the particulate, and nobody cleaned it out. That dust layer becomes a permanent restriction. The Lennox variable-speed motor compensates by drawing more amperage. The high-limit switch trips on the hottest days. The homeowner calls an HVAC tech who replaces the switch twice without ever looking upstream at the ductwork. We’ve seen this exact sequence in Deerfield homes near Wilmot Road, near the older ranch sections south of Lake Cook Road, and throughout the split-level neighborhoods east of the Skokie River. The climate here doesn’t help: elevated spring humidity means that same drywall dust holds moisture against the metal, accelerating surface corrosion inside the plenum. Our approach is to run the camera first, show the homeowner what the renovation left behind, quote a written price for the cleaning and any reconnection work, and deliver before-and-after photos of every duct run. No per-vent pricing, no coupon bait, no surprise line items on the invoice.

Lennox Service Pricing in Deerfield

FAQs - Lennox Air Duct Cleaning in Deerfield
Yes. A return plenum packed with drywall dust from renovation work restricts airflow across the heat exchanger. The Lennox variable-speed blower motor draws harder, the heat exchanger runs hotter, and the limit switch trips as designed. We’ve cleared this exact fault in dozens of Deerfield homes by cleaning the return and blower wheel, not by replacing the switch a third time. Call (224) 351-9772 for an inspection and written estimate.
We use OEM-equivalent parts from quality aftermarket suppliers for blower modules, limit switches, and coil panels. For duct components - flex runs, mastic, and metal connectors - we use commercial-grade materials rated for Lennox temperature swings. We are an independent service provider, not manufacturer-authorized, and we don’t claim warranty endorsement. We do claim parts that fit, function, and hold up.
Deerfield’s Skokie River humidity keeps basement mechanical rooms damp into late spring. Older Lennox sheet-metal ductwork, especially in homes built 1958 to 1985, develops mildew at cabinet seams and inside unsealed return plenums. The blower pulls that odor through the system every cycle. A filter change won’t reach it. We inspect with a borescope and clean with negative-pressure extraction, photographing the before and after inside every run.
Yes. Deerfield split-levels often have long horizontal return runs through finished basements. We access through existing register openings and strategic panel cuts, then restore and seal. Our video inspection shows you exactly what we’re working with before we quote. The camera doesn’t negotiate - it just shows you what’s there. Call (224) 351-9772 to schedule.
It can be either, and often both. Restricted airflow from a debris-clogged evaporator coil or disconnected flex duct downstream causes the coil temperature to drop below freezing. In Deerfield, where additions left flex runs disconnected behind finished ceilings, we’ve found coils iced solid while refrigerant pressures read normal. We clean the coil face, verify duct continuity with the camera, and tell you if the refrigerant side needs separate attention. Call (224) 351-9772 for a written diagnosis.
