We inspect ductwork before recommending cleaning. If the ducts are already in good condition, we explain what we found instead of selling unnecessary work.
We've been doing duct work since 1992, and here's the truth: most Chicago homes don't need duct cleaning. We'd rather lose the sale then scam you. Free camera inspection shows you what's actually in your ducts—no scare tactics, no upsells.
Lets start with the truth. Here's when duct cleaning companies are lying to you:
Made up by duct cleaning companies. There's no EPA, ASHRAE, or NADCA guidline that says this. It's just marketing.
If you had mold issues in your ducts, youd smell it. Real mold requires moisture problems—if you don't have condensation or leaks, you don't have mold.
Usually it's a dirty filter or outdoor allergies. Check and replace the filter as needed before paying for duct cleaning.
Classic bait-and-switch. They show up, "find" mold/damage/extra vents, upsell to $$ +. Legitmate NADCA cleaning can't be done for $.
Visible Mold Growth
Inside ducts (rare, requires moisture problem)
Rodent/Insect Infestation
Droppings, nests, or dead pests in ducts
After Major Renovation
Drywall dust throughout system (6-12 months post-construction)
Excessive Dust Accumulation
1/4"+ layer visible when you look in registers
Never Cleaned, Pre-1980 Home
50+ years of dust (but inspect first)
"Honest answer: Most Chicago homes don't need duct cleaning. Wed rather lose the sale then scam you."
Bernies follows the NADCA standard. Here's our honest proccess:
We run a scope camera through your ducts and show you what's actually there. No guessing, no scare tactics. If your ducts look fine, we'll tell you to save your money.
Time: 15-30 minutes | Cost: FREE
We attach a high-powered vacuum at your furnace to create negative pressure thoughout the duct system. This pulls debris toward the collection unit (not into your house).
Scam companies skip this—they just blow compressed air, which stirs up dust but doesn't remove it.
We insert rotating brushes through each supply and return vent to physicaly dislodge debris from duct walls. This is NADCAs "source removal" requirement—the debris must be physicaly removed, not just stirred up.
Typical debris: Dust, pet hair, drywall dust from renovations, ocasional toys/socks kids dropped in vents.
We document what we removed. Youll see the debris we collected and before/after camera shots of your ducts. Transparancy builds trust.
Time required: 3-5 hours for typical Chicago bungalow
NADCA Certification: National Air Duct Cleaners Association sets the industry standard. Bernie's uses NADCA-certified equipment and processes—source removal, negative pressure, full system inspection.
Most Chicago homes need duct repair, not cleaning. Disconnected or damaged ducts waste 30-40% of your heated/cooled air. We see this all the time in Lincoln Square, Ravenswood, Irving Park - basically anywhere with older homes.
Problem: Boot joints separate in crawlspaces/attics—room gets no airflow
Symptoms: One room always too hot/cold, weak airflow from register
Common in: Chicago bungalows with basement ducts, homes where ducts werent properly secured
Repair cost: $–$$ per duct
Problem: Flex duct flattened by stored items, insulation, or poor installation
Symptoms: Reduced airflow, rooms don't heat/cool properly, furnace runs constantly
Fix: Replace crushed section with proper-sized rigid or flex duct
Repair cost: $–$$ per section
Problem: Cant balance airflow between floors—upstairs too hot in summer, downstairs cold in winter
Fix: Install manual or automatic dampers to control airflow to zones
Benefit: Even temperatures throughout house, lower energy bills
Install cost: $ per damper
Causes: Rodents, age, poor installation (sharp bends, no support)
Result: Conditioned air leaks into attic/crawlspace instead of your rooms—wastes 20-40% of heating/cooling
Fix: Replace damaged section with properly sized, insulated flex duct
Repair cost: $–$$ per section
Common in: Pre-1980 Chicago homes with original metal ductwork
Problem: Holes leak air, reduce efficiency, pull in dusty attic/basement air
Fix: Patch small holes with mastic/mesh, replace badly rusted sections
Repair cost: $–$$ (depends on access)
Chicago homes fact: Most ductwork runs through unfinished basements in bungalows—easy to inspect and repair. Two-flats often have shared ductwork that can spread odors between units (we can install isolation dampers).
No bait-and-switch. No "surprise fees" for "mold we found." Here's what it actually costs:
Camera Inspection:
FREE
We'll show you if cleaning is actually needed
Duct Cleaning (if needed):
$$
Typical home: 1,200-2,000 sq ft, 10-15 registers
Sanitizing (optional):
$
EPA-approved antimicrobial, only if mold/odors present
What we DON'T charge: "Surprise fees" for "extra vents" or "mold we found"
Most homes need 1-3 repairs. We quote before work starts—no surprises.
Average Cost for Typical Chicago Home

Duct cleaning for 1,500 sq ft bungalow with 12 registers
Chicago housing stock has specific ductwork challenges. Here's what we see from Portage Park to Jefferson Park, Albany Park to Edgewater:
Ducts often run through unfinished basements—easy to inspect and repair. Common issues: disconnected boot joints, crushed flex duct from storage, asbestos-wrapped trunk lines (pre-1950). We see a lot of these in North Center, Rogers Park, and West Ridge.
We can inspect your basement ducts during free camera inspection
Shared ductwork can spread odors between units (cooking smells, smoke). We can install isolation dampers to prevent cross-contamination while maintaing airflow. Common in Andersonville, Bridgeport, Logan Square and Humboldt Park.
Damper install: $ per zone
Contractors often don't protect registers during drywall work—fine dust thoughout system. This is one of the few times duct cleaning is actually necessary. Wait 6-12 months post-move-in for dust to settle.
Camera inspection shows if cleaning is needed
May have asbestos-wrapped ducts. DON'T disturb or clean these yourself—requires licensed abatement specialist. We can identify asbestos-wrapped ducts during inspection and refer you to specialists. Very common in Hyde Park, Pilsen, Wicker Park and Ukrainian Village.
Asbestos abatement required before duct cleaning
Realistic timeline based on 15+ years of Chicago HVAC experience:
Clean 6-12 months after construction dust settles. Contractors rarely protect registers—drywall dust gets eveywhere.
Cost: $$ typical
Maybe every 10-15 years IF you see visible dust accumulation (1/4"+ layer in registers). Most homes never need cleaning.
Free camera inspection shows if cleaning is needed
Doesnt change much. Pet hair gets trapped in your filter, not the ducts. Check and replace the filter before paying for duct cleaning.
Good filter > duct cleaning for pet allergies
Check and replace your filter before paying for duct cleaning. Most allergies are outdoor pollen or dirty filters, not duct dust.
Try monthly filter changes for 3 months first
"We're HVAC techs, not duct cleaning salespeople. If your ducts look fine in the camera, we'll tell you to save your money."
Honest answer: Most Chicago homes don't need duct cleaning every 3-5 years like cleaning companies claim. Unless you have visible mold, rodent infestation, major renovation dust, or 1/4"+ dust accumulation in registers, you probably don't need it. Wed rather lose the sale then scam you. We offer free camera inspections—we'll show you what's actually in your ducts.
Duct cleaning costs $$ for a typical Chicago home (1,200-2,000 sq ft, 10-15 registers) using NADCA-certified equipment. Camera inspection is FREE. We don't do bait-and-switch $ specials that turn into $$ + after they "find" problems. Transparant pricing, no surprise fees.
Probaly not. Most allergies are caused by outdoor pollen or a dirty filter (costs $ to replace monthly). Dust in ducts is minimal compared to what your filter catches. Before spending $$ on duct cleaning, try changing your filter monthly for a few months. We're HVAC techs, not duct cleaning salespeople.
Proper NADCA-certified duct cleaning takes 3-5 hours for a typical Chicago bungalow. Companys that promise "2 hours for your whole house" are cutting corners—probably just blowing compressed air without actually removing debris. Real duct cleaning requires negative pressure systems and rotary brushes at each register.
Duct cleaning removes dust and debris from inside ducts. Duct repair fixes physical damage—disconnected flex ducts, crushed sections, torn ductwork, rust holes. Honestly, duct REPAIR is more common and more usefull than cleaning. Disconnected ducts waste 30-40% of your heated/cooled air.
Yes. We offer FREE camera inspections—we'll scope your ducts and show you what's actually there. If cleaning is needed, we quote it on the spot. If your ducts look fine, we'll tell you to save your money. No pressure, no bait-and-switch.
Free camera inspection for homes in Lakeview, Lincoln Park, Bucktown, Old Town and across Chicago. No scare tactics, no upsells. If your ducts look fine, we'll tell you to save your money. That's the Bernies difference.
Camera inspection takes 15-30 minutes. We show you what's there before recommending anything.
