How Can I Seal a Leaking Air Duct to Improve HVAC Efficiency?
The most effective way to seal a leaking air duct is to have a technician inspect and seal it during a full-system duct service. Our team opens ductwork for thorough access and follows manufacturer instructions, which helps restore airflow and reduce energy use. Seasonal cleanings also remove dust, allergens, and odors that can mimic leak symptoms and restrict flow. Schedule service before each season in Peru, Logansport, or Wabash. Free estimates and a one-year parts and labor warranty apply.
- Request leak inspection during seasonal duct cleaning.
- Ensure ducts are opened rather than only vacuumed through vents.
