Duct Services in Charleston, SC
Your ductwork is the hidden network that delivers heated and cooled air throughout your home or business. When ducts are clogged, leaking, or damaged, they not only reduce comfort but also increase energy costs and impact indoor air quality. At Dependable Heating and Air, we provide comprehensive duct services in Charleston, SC, including cleaning, sealing, repair, and full duct replacement. Our goal is to keep your HVAC system operating efficiently while ensuring clean, consistent airflow in every room.
Why Ductwork Matters for Comfort and Efficiency
Ducts play a vital role in moving conditioned air, but over time, they can develop problems that affect both performance and health.
Charleston’s humid climate makes ductwork especially vulnerable to mold growth, dust buildup, and leaks. Leaky ducts allow air to escape into attics or crawl spaces, forcing your HVAC system to work harder and increasing utility bills. Dirty or damaged ducts also circulate pollutants such as dust, pet dander, and mold spores, reducing indoor air quality.
Professional duct services restore efficiency, improve airflow, and protect your indoor environment.
Duct Cleaning in Charleston, SC
Dust, debris, and allergens accumulate inside ducts over time, especially in homes near the coast where salt and moisture contribute to buildup. Our duct cleaning service removes contaminants that can affect both system performance and indoor air quality.

We use specialized equipment to clean ducts thoroughly, restoring unrestricted airflow and helping reduce allergy and asthma triggers. Regular duct cleaning also minimizes strain on your HVAC system, extending the life of your equipment.
Duct Sealing Services
Leaky ducts are one of the most common hidden problems in HVAC systems. Studies show that leaky ductwork can waste up to 30% of conditioned air, driving up energy costs.
