Answers to Common Questions
View All FAQsHow much does air duct replacement cost for a typical home?
Air duct replacement cost for a typical home is not a flat price; it’s set after an in‑home assessment of duct size, layout, material, and access. The biggest cost driver is scope—full system replacement versus a few runs—followed by how hard the ducts are to reach. If your ducts are leaky but still sound, Aeroseal duct sealing (a patented from‑the‑inside process our team offers) can close leaks without tearing into walls or ceilings and may be more cost‑effective than replacement. In finished ceilings or tight crawlspaces, every joint and boot must be remade and sealed, which adds labor time. Our crew regularly performs duct replacements and Aeroseal sealing across the St. Louis area.
- Choose replacement when ducts are crushed, missing, severely rusted, or contaminated.
- Choose sealing when ducts are intact but losing air through leaks.
- Choose repair when damage is isolated to a short section. Schedule an on‑site evaluation to get an accurate quote and clear repair‑versus‑replace options. <br/>

Duct leaks are best sealed with Aeroseal duct sealing, a patented process that seals leaks from the inside of your ductwork to improve HVAC efficiency. Most energy loss comes from hidden gaps that let 20–30% (sometimes even up to 40%) of conditioned air escape. Aeroseal starts with a leakage assessment using software that shows how much your ducts are actually leaking, then uses controlled air pressure so sealing particles stick to the leak edges until they close. This inside-out method helps restore airflow to the rooms that need it and reduces dust pulled in by return-side leaks. Our team provides this indoor air quality–focused sealing service throughout the St. Louis area, including neighborhoods around Eureka.
Consider duct sealing if you notice:
- Rooms that run hot or cold compared to the rest of the home
- Dust collecting around registers or surfaces getting dusty fast
- Utility bills that seem high for normal system use
- An older home with comfort or dust complaints
Start with a professional leakage assessment so you fix the actual loss instead of covering symptoms.
