Birmingham Metro Duct Cleaning

AIR DUCT
CLEANING

Years of red clay dust, Alabama pollen, pet dander, and mold spores accumulate in your ductwork. You breathe it every time the system runs. We clean it thoroughly — not a drive-by blow-and-go, but actual contaminant removal.

Signs Your Ducts Need Cleaning

Dust Blowing from Vents

If you can see dust puffs coming from supply registers when the system starts, there's significant buildup in the duct system. This is the most obvious visible sign.

Musty or Stale Odors

Musty smells when the HVAC runs often indicate mold growth in the ductwork or air handler. Alabama's humidity creates favorable conditions for mold in HVAC systems, especially in homes with moisture intrusion history.

Allergy Symptoms Indoors

Symptoms that worsen when the HVAC runs — sneezing, congestion, eye irritation — can point to contaminated ductwork distributing allergens throughout the house.

Never Been Cleaned

If you've owned your home for more than 5-7 years and have never had the ducts cleaned, it's probably time. If you don't know the history of a purchased home, an inspection is warranted.

Recent Renovation Work

Construction dust from remodeling projects infiltrates duct systems and can coat surfaces throughout. If you've had significant renovation work, duct cleaning should follow.

Older Home with Original Ductwork

Many older Birmingham homes in Homewood, Mountain Brook, and Vestavia Hills have original ductwork with decades of accumulated debris. The interior of 40-year-old ductwork that's never been cleaned can be significantly contaminated.

Our Duct Cleaning Process

We use a negative pressure vacuum system combined with mechanical agitation to remove contaminants from duct surfaces. Here's what the process looks like:

1
Inspection First

We inspect accessible duct sections before cleaning to assess contamination type and level, duct material condition, and any areas that need special attention. This also identifies any duct damage or disconnections that should be repaired.

2
Negative Pressure Setup

We connect a high-powered vacuum to the main trunk line to create negative pressure throughout the system. This pulls loosened debris toward the vacuum rather than back into the living space.

3
Agitation and Removal

We use rotating brushes and compressed air tools to dislodge contaminants from duct walls, registers, and grilles. Each supply and return is addressed individually.

4
Air Handler and Coil Cleaning

The air handler cabinet, blower wheel, and accessible portions of the evaporator coil are cleaned as part of a complete duct cleaning. Contaminants in the air handler go right back into clean ducts if left unaddressed.

5
Final Inspection and Test

We run the system and verify airflow from all registers. We show you before-and-after photos of representative duct sections.

Duct Cleaning FAQ

How do I know if my ducts need cleaning?

Visible dust from vents, musty odors when the system runs, allergy symptoms that are worse indoors, or more than 5-7 years since the last cleaning are all good reasons to have an inspection. We'll look and give you an honest answer about whether cleaning will provide meaningful benefit.

Is duct cleaning worth the money?

For homes with significant contamination — older construction, pet dander, moisture history, visible mold — yes, absolutely. For relatively new homes with clean systems, the benefit is more modest. We'll tell you honestly where your home falls before you spend money.

How long does duct cleaning take?

Typically 3-5 hours for a single-story home, longer for two-story homes or complex layouts. We don't rush the job — the vacuum needs time to do its work.

Should I be home during duct cleaning?

Someone needs to let us in and be accessible if we have questions. You don't need to hover over us, but being home or having someone there is required.

Does duct cleaning improve energy efficiency?

Heavily contaminated ductwork does restrict airflow and can increase system run times. Cleaning removes that restriction. The efficiency improvement in most residential cases is modest but measurable.
