The honest truth about duct cleaning

The HVAC industry has an ugly underbelly of "$69 whole-house duct cleaning" advertising that's really a bait-and-switch — once on-site, the technician finds "necessary additional services" that bring the actual bill to $1,500-$3,000. Or worse, they vacuum a few registers, leave the rest untouched, and call it done. The EPA explicitly warns about these scams.

Here's our position: most homes don't need duct cleaning. When they do, it's a real service that takes 4-6 hours and costs $595-$1,295 done properly. We'll do the in-home assessment first, give you an honest opinion on whether your system actually needs it, and if not, point you at what does need attention instead.

When you DO need duct cleaning

• Visible mold inside ducts — verified by inspection through register openings or borescope, not by smell alone
• Construction or renovation debris — drywall dust, sawdust, insulation fibers in the duct system after a recent project
• Rodent infestation evidence — droppings at registers, scratching sounds, urine smell traced to ducts
• Insect infestation — visible nests or droppings in registers
• Significant pet hair/dust buildup at supply registers (handful or more of debris when register is removed)
• Persistent musty smell traced to ductwork (not the coil — that's a UV light job)
• Post-fire or smoke damage
• Recent water damage event that may have reached ductwork

When you DON'T need duct cleaning

• "It's been a few years since the last cleaning" — not a reason on its own
• Allergies/asthma in the household (usually doesn't help)
• Higher-than-expected dust buildup on furniture — filter issue, not duct issue
• Just bought a new house and want a "fresh start" — usually unnecessary unless prior owner had heavy pets or smoking
• Following a flu season — viruses don't survive long enough in ducts to matter
• Sales pitch from a competitor citing "deep contamination" without visible evidence

Our process (when warranted)

1. Pre-cleaning assessment — visual inspection through registers and access points, borescope into trunk lines if needed. Photo documentation of conditions.
2. Cover all registers to maintain negative pressure isolation
3. Connect HEPA-filtered negative-pressure equipment to the trunk line or return drop — high-CFM vacuum that pulls debris while preventing contamination of living space
4. Agitate inside ducts systematically — rotating brushes for rigid ducts, air whips for flex ducts, working from far-end registers back toward the air handler
5. Clean the blower compartment — squirrel cage blower, motor housing, internal air handler surfaces
6. Coil cleaning — evaporator coil (the wet side, where most biological growth happens) brushed and treated with EPA-registered cleaner appropriate for HVAC use
7. Sanitization of accessible surfaces with EPA-registered antimicrobial — only on the metal duct surfaces, never sprayed into the airflow
8. Filter replacement — fresh filter installed (we bring the right size)
9. System test and verification
10. Post-cleaning photos showing the same locations from the pre-assessment

NADCA (National Air Duct Cleaners Association) defines the standards for proper duct cleaning. We follow the NADCA process even though we're not a NADCA-member shop — the process is the right way to do the work regardless of trade association affiliation.

Pricing transparency

Add-ons quoted separately if applicable: dryer vent cleaning ($95), bathroom exhaust ducts ($125), kitchen range hood duct ($145).

What we DON'T do

• "$69 whole-house" pricing followed by upsells
• Aerosol sealants ("Aeroseal" is a legitimate separate service we offer; we don't apply random sealants as part of cleaning)
• Selling air purifiers or UV lamps as part of the cleaning visit (separate consultation)
• Pressure-washing ductwork (creates moisture problems)
• Toxic chemical fogging (EPA does not endorse this for residential HVAC)

Better alternatives to consider first

Before duct cleaning, consider whether these address your actual concern:

• Filter upgrade. 1" MERV-4 → 4" MERV-11 media filter ($395-$695). Stops new buildup at the source.
• UV-C lamp at the coil. Kills mold and biofilm where they grow ($395-$795).
• Whole-house dehumidifier. Removes the moisture that enables mold growth in the first place ($1,895-$2,695).
• Duct sealing (Aeroseal). If the problem is air leakage rather than dirt — different service entirely.

Most Lebanon homes that "feel like" they need duct cleaning are actually better served by one of these upgrades.
