Gap Air Conditioning - El Paso's Trusted HVAC Services

Common signs include your AC blowing warm or lukewarm air, ice forming on the refrigerant lines or evaporator coil, a noticeable hissing or bubbling sound from the unit, and a sudden spike in your energy bill as the system works harder to cool. In El Paso's heat, even a small leak can significantly reduce cooling capacity. If you notice these signs, it's best to call for a professional diagnosis and repair to prevent further damage and restore efficiency.

Leaking ducts force your HVAC system to work much harder to push air through your home, leading to uneven temperatures from room to room, weak airflow from vents, and excessive dust. Most importantly, you're paying to condition air that escapes into your attic or crawlspace instead of your living areas. In El Paso, where we rely heavily on cooling, sealing these leaks is one of the most effective ways to improve comfort and lower your monthly energy costs.

Our professional duct sealing starts with a thorough inspection using specialized tools to locate all leaks, often in hard-to-reach connections at joints and bends. We then seal these leaks with durable mastic sealant or metal-backed tape—not standard household tape, which fails quickly. For accessible ducts in attics or crawlspaces, we may also apply an aerosol-based sealant. This comprehensive approach ensures your duct system is airtight, maximizing airflow to every room and improving your system's overall efficiency and lifespan.
