    Common Heat Pump Repair Problems in Foster City

    Heat pump not heating

    A faulty reversing valve, low refrigerant, or defrost board issue can prevent heating. We'll restore warmth fast.

    Heat pump not cooling

    Reversing valve stuck, compressor issue, or refrigerant leak. We diagnose and fix all heat pump cooling failures.

    Heat pump running constantly

    Often indicates low refrigerant, a dirty filter, or undersized equipment. We'll optimize performance and efficiency.

    Ice buildup on outdoor unit

    A failing defrost cycle, low refrigerant, or airflow restriction can cause ice. We'll restore proper defrost operation.

    Heat pump making strange noises

    Clicking, grinding, or whooshing sounds may indicate valve, compressor, or fan issues. We'll identify the source.

    Auxiliary heat running too often

    If the heat pump can't keep up, auxiliary strips engage excessively. We'll diagnose why the primary system underperforms.
