NELSON'S HEATING & AIR | Reliable HVAC Services in Marble Falls, TX

Common signs in our area include short cycling (frequent on/off cycles), inability to maintain a consistent temperature, excessive humidity indoors, and unusually high energy bills. An oversized system cools or heats too quickly without properly dehumidifying, while an undersized one runs constantly and struggles. We perform a Manual J load calculation to determine the precise size your home needs.

Poor airflow in Marble Falls homes is often due to clogged air filters, blocked or leaky ductwork, a failing blower motor, or closed dampers. Restricted airflow forces your system to work harder, reducing comfort and efficiency. We conduct a comprehensive airflow analysis, inspecting and cleaning ducts, sealing leaks, and ensuring all components are functioning correctly to restore optimal airflow throughout your home.

Absolutely. Many airflow problems are resolved through duct sealing, balancing, or component repair. For sizing issues, if your system is only slightly off, we can often optimize its performance with controls and zoning. However, if the unit is severely mismatched, a replacement may be the most efficient long-term solution. We provide honest, upfront assessments and prioritize repairs when they make sense for your comfort and budget.
