Aerosealing ductwork is an advanced duct‑sealing service that uses a specialized aerosol mist to find and seal leaks from the inside of your HVAC ducts, improving system efficiency and reducing air loss without tearing into walls. By closing gaps and cracks that waste heated or cooled air, it can lower energy bills, enhance comfort with more even temperatures, improve indoor air quality by keeping out dust and allergens, and reduce strain on your HVAC system for longer equipment life — all through a fast, non‑invasive process offered by High Efficiency Energy Solutions.
