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.
Fast, Reliable HVAC Cleaning Across Evanston
HVAC cleaning in Evanston, IL typically runs between $390 and $780 for a full system when handled by a company that provides written pricing before work begins. For many homes here, especially those built before 1940, the real cost driver isn’t dirt volume alone. It’s the condition of the ductwork itself. CleanRun Air Duct Cleaning has worked in Evanston long enough to know which streets near the lake carry humidity problems and which century-old systems hide asbestos-containing materials behind the register grilles. If you want a price in writing before anyone touches a panel, call (806) 606-6902.
Why CleanRun Air Duct Cleaning Is Evanston’s Preferred HVAC Cleaning Company
CleanRun Air Duct Cleaning was founded in 2013 and has since served 52,000+ homes, every single one with a written price before work started and a documented photo record when the crew left. We’re independently owned and operated under the Haven Standard, which means a handful of non-negotiable clauses govern every Evanston job. Clause 1: written pricing before any work begins. Clause 3: verified, background-checked, uniformed crews. Clause 4: a documented photo record of every duct run, before and after, delivered to you as part of the standard job file.
Our Evanston customers tend to be thorough researchers. They’ve bought older homes at high prices and they want evidence that the work was actually done. That’s exactly what we provide. Tomas Reyes, who leads CleanRun, built the company around a simple premise: show the customer the inside of their ducts before asking them to believe anything. A 1920s plenum with a three-inch debris shelf at the first elbow doesn’t need a sales pitch. The camera shows it.
We field calls for Evanston jobs from our Chicago scheduling office, and crews serve Evanston locally, so we know the parking constraints near Davis Street, the narrow service alleys behind Ridge Avenue apartment buildings, and the older mechanical rooms common in the city’s historic districts.
Our HVAC Cleaning Services in Evanston

Our HVAC Cleaning team handles four core components of your system. Most Evanston jobs involve at least two of them, and many involve all four. Here’s what each one actually means, in plain terms.
Evaporator Coil Cleaning
The evaporator coil sits above your furnace or inside your air handler and gets cold when the AC runs. In Evanston’s humid lakefront air, that cold surface condenses moisture constantly through the cooling season. Dust sticks to the wet coil, then more dust sticks to that dust. We find coils east of Ridge Avenue with a felted gray mat thick enough to block airflow by 30 percent or more. We clean the coil with professional-grade equipment from brands like Rotobrush and Nikro, then photograph it before and after. In Evanston, a typical evaporator coil cleaning runs $180 to $340 depending on access.

Blower Cleaning
The blower wheel is the fan that pushes conditioned air through your ducts. When the wheel’s fins are caked with dust, the system moves less air and runs longer cycles, which adds wear and cost. In older Evanston homes with original furnace cabinets, access to the blower can be tight, which is why we quote the job after seeing the mechanical closet, not from a phone call. A blower cleaning in Evanston typically runs $120 to $220, and it’s often combined with coil cleaning on the same visit.

Condenser Cleaning
The condenser is the outdoor unit, and in Evanston it’s usually sitting in a tight side yard or behind a vintage garage on a brick pad. Cottonwood from lakefront parkways, maple pollen from the city’s mature tree canopy, and debris from storms off the lake all clog the fins. We remove the outer panels, clear the fins with low-pressure wash and coil-safe cleaner, and check the refrigerant line insulation. Condenser cleaning in Evanston runs $110 to $190.

Air Handler Cleaning
In many pre-1940 Evanston homes, the air handler is a modified gravity-furnace cabinet, not a standard modern unit. Interior surfaces collect dust, and the old cabinet relies on sealing that may have failed decades ago. We clean the interior surfaces with HEPA-filtered negative-pressure equipment from Abatement Technologies, then inspect the plenum connections. Air handler cleaning in Evanston typically runs $150 to $280, though the older and less standard the installation, the more we need to see before quoting.

AfterTrusted Brands We Service in Evanston
We work on systems built around Honeywell controls, Aprilaire filtration, and Guardsman air quality components, among others. What matters for Evanston customers is that we don’t ask you to replace a functioning brand-name component just to simplify the job. If a Honeywell humidifier or Aprilaire filter housing is in good shape, we clean and service it. If it’s beyond salvage, we document why with photos and give you a written recommendation. Parts for common configurations are stocked locally, so most Evanston HVAC cleaning jobs complete in a single visit without a parts run.
Common HVAC Cleaning Problems We See in Evanston Homes

- Asbestos-containing duct wrap halting the job. Homes built before 1940, particularly near Northwestern and along the lakefront districts east of Ridge Avenue, often have original duct runs wrapped in asbestos-containing tape or millboard. When our inspection finds it, cleaning stops. Legally, a licensed abatement contractor must remove the material before we can touch the ductwork.
- Lakefront humidity driving mold recurrence. East of Ridge Avenue, the near-continuous onshore airflow from Lake Michigan pushes humidity into basements and crawlspaces. Uninsulated sheet-metal ducts cool below dew point, condensation forms, and biological growth follows. A clean without addressing condensation means mold returns within months.
- Irregular-diameter gravity ductwork resisting standard tools. The “octopus” gravity systems common in Evanston’s 1890s-1930s homes have runs of wildly varying diameter. Standard agitation brushes can either miss debris in the wide sections or damage joints in the narrow ones. We assess each run individually and adjust tools accordingly.
- Degraded cloth-tape joints leaking conditioned air. Original early forced-air systems were sealed with cloth tape that has since dried and fallen away. That means the air you’re paying to heat or cool is leaking into wall cavities and attics. After cleaning, sealing these joints is often the single highest-value fix in an older Evanston home.
Pricing for HVAC Cleaning in Evanston, IL
Let’s be direct, because written pricing is the entire point of CleanRun. A whole-system HVAC cleaning in Evanston, covering evaporator coil, blower, condenser, and air handler, typically lands between $390 and $780. Evaporator coil cleaning alone runs $180 to $340. Blower cleaning runs $120 to $220. Air handler cleaning runs $150 to $280. Condenser cleaning runs $110 to $190. If our duct inspection uncovers asbestos-containing materials, the price changes, because abatement is a licensed, separate process that we legally cannot perform. If we find significant sealing failures, we’ll quote the sealing work as a separate line item in writing. You’ll never get a per-vent price from us, and we will never start work without a written number agreed to first. That’s Haven Standard Clause 1.

FAQs - HVAC Cleaning in Evanston

Duct cleaning stops mid-job in Evanston’s older homes because pre-1940 duct systems often contain asbestos in their original wraps, tape, or millboard, and state law requires a licensed abatement contractor to remove that material before any cleaning continues. We inspect before we clean, so we typically identify the issue before tools come off the truck. If you already have a competitor’s stop-work notice, bring it to us for a Free Second Opinion on any written estimate. Call (806) 606-6902.
Homes east of Ridge Avenue in Evanston sit in a lakefront microclimate with near-continuous onshore airflow from Lake Michigan, which keeps relative humidity measurably higher than in Wilmette or Skokie just a few miles west. That moisture condenses on uninsulated sheet-metal ducts and gives biological growth a foothold. If your ducts aren’t insulated and you’re east of Ridge, condensation is a structural issue, not a cleaning issue, and we’ll document it in your photo record.
An octopus gravity duct system is an early heating design, common in Evanston homes built between the 1890s and 1930s, where a central register sprouts multiple round ducts of varying diameter that rely on warm air rising rather than a fan pushing it through. It is harder to clean because standard agitation tools are sized for modern uniform ducts, and the irregular diameters mean a tool that fits one run can damage the next. We assess each run visually and adjust the equipment, photographing every section before and after.
Yes, we can clean ductwork with original cloth-tape sealing and irregular diameters, and that describes most of the older systems in Evanston. The cloth tape is usually degraded, and part of the job is documenting where it has failed. Cleaning removes the debris, but sealing the failed joints afterward is what keeps your conditioned air in the duct rather than leaking into wall cavities. We quote the sealing as a separate written line item after we see the condition of the runs.
You won’t know definitively without testing, but certain signs make asbestos presence likely: pre-1940 construction, original duct runs, white or gray fibrous wrap at joints, and millboard panels inside the plenum. In Evanston’s lakefront districts and the historic neighborhoods around Northwestern, these indicators are extremely common. We flag anything suspect during inspection and stop work until licensed abatement clears the run. That protects you legally and protects our crew.
If you have more questions about HVAC cleaning in Evanston, or if you want a written price before any work starts, call CleanRun Air Duct Cleaning at (806) 606-6902. We photograph every duct run, write every price before tools come out, and back every job with the 365-Day Done Right Promise, in writing.
