Top-Rated HVAC Repair in Sellersburg, IN 47172 - AASM Heating & Cooling

A building energy audit is a comprehensive assessment that identifies exactly where your home is losing conditioned air. In our Sellersburg area, a primary culprit is often leaky ductwork in attics or crawlspaces. Our audit uses tools like a blower door test to measure total home leakage and thermal imaging to visualize specific drafts and duct leaks. By locating and sealing these leaks, we can significantly improve airflow balance and reduce the strain on your HVAC system, leading to lower bills and more consistent comfort room-to-room.

Yes, a refrigerant leak is a common issue here that causes poor cooling and can damage your compressor. We start by checking system pressures and performance. To find the exact leak location, we use electronic leak detectors and, if needed, inject a fluorescent dye into the refrigerant line. This precise method allows us to pinpoint even small leaks at connections or within coils. Repairing the leak and restoring the correct refrigerant charge is crucial for efficiency, cooling power, and preventing costly component failure.

Once we map the leaks in your duct system using audit data, our sealing process is thorough. We use professional-grade mastic sealant or metal-backed tape (not standard duct tape) to permanently seal leaks at joints, connections, and seams. For accessible ducts in attics or basements, we seal from the outside. In some cases, we may recommend and install new sections of ductwork if damage is severe. Properly sealing ducts is one of the most effective ways to improve airflow to all your vents, enhance indoor air quality by preventing dust intake, and boost your system's overall efficiency.
