Air Ducts Need a Good Cleaning

Dirty air ducts can lower your home’s air quality, worsen allergies and asthma, and reduce your HVAC system’s efficiency. Here are the top signs that indicate it’s time for a professional duct cleaning service.

Dusty Vents

You start to notice an accumulation of dust and debris coming out of your floor or wall vents. Over time, dust and other particles build up inside your ductwork and eventually work their way into your living areas through the vents. Regularly cleaning dust bunnies out of vents only treats the symptom, not the cause.Dust or debris visible in vents.

Musty Odors

When your HVAC system turns on, you notice an unpleasant moldy or musty odor. This indicates that dust, debris, skin cells, pet dander and microbes have built up inside the ducts and are creating a breeding ground for mold and bacteria.

Allergy and Asthma Flare-Ups

If you or members of your family suffer from allergies or asthma, duct cleaning can help eliminate common triggers trapped in your ventilation system. Dust and microbes inside ducts are released into your home’s air and can worsen symptoms over time.

Poor Airflow and Distribution

Restricted ductwork reduces the efficiency of your HVAC system and leads to uneven heat and AC temperatures throughout your home. Air can’t properly circulate through clogged ducts.

Higher Energy Bills

Dirty ductwork requires your HVAC system to work harder to force air through, increasing energy usage and utility costs. Regular cleaning improves airflow and system efficiency.

After Renovations or Repairs


Anytime ducts are opened for work, particles are disturbed that then lodge inside the system. It’s wise to have ducts thoroughly cleaned afterward to remove residual dust and debris.

Duct Age

Over 10 to 15 years, contaminants naturally accumulate inside ducts through regular use. The older your ductwork, the more likely it needs a deep clean.
