When the air ducts leak, your wallet suffers. Flaws in the ductwork often waste 20 to 30% of heated/cooled air, contributing significantly to household energy costs. Plus, when conditioned air is lost, the entire HVAC system needs to run longer and work harder, increasing the risk of repairs and shortening service life. For professional duct sealing, turn to the knowledgeable and experienced specialists from Cape Cod Mechanical Systems LLC. Our results are unmatched.

Duct Sealing from Cape Cod Mechanical Systems LLC

Holes, cracks and separation at ductwork seams invite dust, pests, insects and other contaminants inside. Along with obstructing airflow, this debris negatively affects indoor air quality. Every time the heating or cooling system starts up, pollutants such as mold spores and bacteria can become airborne and spread throughout the home. Look no further than Cape Cod Mechanical Systems LLC for the many benefits of duct sealing in Cape Cod, Yarmouth, and surrounding areas.
