Pricing Guide
What’s the Average Cost of Air Duct Cleaning?
For a standard single-family home, professional air duct cleaning typically runs between $300 and $600. Here’s a cleaner breakdown by home size:
These are fair-market Chicago rates as of 2026. Prices can shift based on your neighborhood, the age of your ductwork, and what the company finds inside. AL Home Services covers all Chicago neighborhoods — see our Chicago air duct cleaning page for local pricing and same-day availability.
Price Factors
What Factors Change the Price?
Not every home is the same, and honest companies will adjust their quotes based on a few real variables.
1. Number of Vents and Returns
Most pricing starts with a per-vent model — typically $25 to $45 per supply vent, plus additional cost for return air vents. A bungalow with 15 vents will cost noticeably less than a three-flat with 40+.
2. Mold or Microbial Growth
Humidity, especially in older homes with basement ductwork, creates the perfect environment for mold. If your technician finds microbial growth, mold treatment and sanitization adds $200–$600 depending on severity. According to the EPA’s indoor air quality guidelines, mold in ductwork should always be professionally treated — not masked.
3. Duct Material and Accessibility
Flexible ducts (common in older housing stock) can be trickier to clean than sheet metal. If your ducts run through tight crawl spaces or are partially inaccessible, expect a small upcharge.
4. System Add-Ons
Some homeowners add dryer vent cleaning at the same appointment — that typically runs $100–$175 and is genuinely worth doing, since clogged dryer vents are a leading cause of house fires.
5. HVAC Component Cleaning
Coil cleaning, blower cleaning, and UV light installation are sometimes bundled in. Ask your provider what’s included before booking.
Warning
The $49 Scam — How to Spot It
This one is worth its own section because it’s rampant in the area.
You’ve probably seen ads or door hangers promising whole-house air duct cleaning for $49 or $79. These are almost always bait-and-switch operations. A technician shows up, does a cursory inspection, and then quotes you $800–$1,500 in “necessary add-ons.” If you decline, they leave without doing meaningful work.
The National Air Duct Cleaners Association (NADCA) has put out clear warnings about this practice. Legitimate cleaning of a medium-sized home simply cannot be done profitably for under $200 — the equipment, labor, and time don’t allow for it.
Red flags to watch for:
- No physical address or local presence
- No mention of NADCA certification or HEPA equipment
- Pressure to decide on the spot
- No itemized quote before work begins
What’s Included
What Does a Legitimate Air Duct Cleaning Include?
When you hire a reputable company like AL Home Services, here’s what a proper cleaning should cover:
Full Inspection
Complete ductwork inspection before any work begins
HEPA Vacuuming
HEPA-grade vacuuming of all supply and return vents
Debris Removal
Agitation tools to dislodge stuck debris from duct walls
Sanitization
Sanitization treatment if needed (separate from basic cleaning)
Documentation
Before-and-after documentation so you can see the difference
System Check
Final system check to confirm airflow is restored
NADCA’s ACR standard recommends cleaning every 3 to 5 years under normal conditions — more frequently if you have pets, allergies, or recent renovation work.
Value Analysis
Is It Worth the Cost?
Yes — and here’s the practical reason why.
Chicago homes run heating systems hard from October through April. That’s six-plus months of the same air cycling through your ducts. The Department of Energy estimates that 25–40% of heating energy is wasted due to dirty or leaky HVAC systems. Clean ducts improve airflow, reduce strain on your furnace, and can meaningfully lower your monthly utility bill.
If anyone in your home has asthma, seasonal allergies, or respiratory issues, the American Lung Association specifically recommends regular HVAC and duct maintenance as part of managing indoor air quality.
The math is straightforward: a $350–$500 cleaning every few years, versus potential medical costs, HVAC repairs, or energy waste. It pays for itself.
