Why is air duct cleaning so expensive?

Professional duct cleaning requires truck-mounted equipment costing $50,000+, NADCA-certified technicians, 2-4 hours of labor, and liability insurance. Companies charging under $100 are using inferior equipment and cutting corners.

Is cheap air duct cleaning worth it?

No. Companies offering $49-$99 whole-house specials typically use portable shop vacuums instead of truck-mounted equipment, clean only what's visible, and then upsell unnecessary services. You get what you pay for.

Q: How much does air duct cleaning cost?

Air duct cleaning costs $199-$499 for most residential homes in Central Texas. The national average is $300-$500. Prices depend on home size, number of vents, HVAC systems, level of contamination, and whether add-on services like sanitization are included.

Planning to get your air ducts cleaned? Here's a transparent, no-BS breakdown of what you should expect to pay — and how to avoid overpaying (or underpaying for a scam).

Cost by Home Size

Small Home

Under 1,500 sq ft • 6-10 vents

$199–$299

Average Home

1,500–2,500 sq ft • 10-18 vents

$299–$399

Large Home

2,500–4,000 sq ft • 18-25 vents

$399–$499

Commercial

Offices & retail • 25+ vents

$500–$1,200+

What Affects the Price?

Number of vents/registers — the primary pricing factor
Number of HVAC systems — multi-system homes cost more
Level of contamination — heavy mold or pest debris requires extra work
Accessibility — attic ductwork or crawl spaces add complexity
Add-on services — sanitization (+$75-$150), dryer vent cleaning (+$100-$175)

Per-Vent vs. Flat-Rate Pricing

Some companies charge per vent ($25–$45 per vent) while others offer flat-rate pricing. Both can be fair — the key is understanding what's included. At Bastrop Air Duct Cleaners, we offer transparent flat-rate pricing that includes all supply vents, return vents, the main trunk line, and a basic sanitization treatment.

⚠️ Price Red Flags

Under $100 for the whole house — always a bait-and-switch
"Per room" pricing — vague and designed to upsell
No upfront quote — insist on a written estimate before work begins
Quoting without seeing your system — legitimate companies need to assess your home

What Should Be Included?

Cleaning of all supply and return ducts

Main trunk line cleaning

HVAC system inspection

Before-and-after visual documentation

Basic sanitization/deodorization

Is It Worth the Investment?

For a service that improves your air quality, reduces allergens, extends your HVAC system's lifespan, and can lower energy bills by up to 25-40% (according to the DOE), $200-$400 every 3-5 years is one of the best home maintenance investments you can make. Compare that to a new HVAC system at $5,000-$15,000 — prevention is always cheaper than replacement.
