• ❓ Frequently Asked Questions

    How much energy do leaky ducts waste in Buena Park homes?

    Leaky ducts typically waste 20-30% of conditioned air before it reaches your living spaces, according to the U.S. Department of Energy. For a Buena Park home spending $200 monthly on heating and cooling, that represents $40-60 lost every month to duct leakage—money spent cooling your attic instead of your home.

    Can I seal duct leaks myself or should I hire a professional?

    While you can seal accessible duct connections using proper mastic sealant (not duct tape), most significant leaks occur in hidden areas behind walls, above ceilings, or in tight attic spaces. Professional duct sealing reaches all leak points and includes pressure testing to verify results. For comprehensive sealing, contact Shalom Heating & Air at (714) 886-2021.

    What causes ductwork to develop leaks over time?

    Duct leaks develop from several factors: deterioration of older duct materials like fiberglass, separation of connections due to vibration and temperature cycling, dried-out tape or mastic at joints, and physical damage from pests or roof work. Southern California's extreme attic temperatures accelerate material breakdown in older duct systems.

    How long does professional duct sealing last?

    Professional duct sealing using modern mastic sealants or aeroseal technology typically lasts 15-20 years when properly applied. The longevity depends on duct material quality, attic temperature extremes, and whether the underlying ductwork remains structurally sound. Quality sealing is a long-term investment that continues saving energy for decades.
