We diagnose the specific cause through system testing and visual inspection, then provide targeted repairs such as refrigerant recharging, coil cleaning, or component replacement. For Novato homeowners, we also recommend regular maintenance to prevent efficiency drops, including checking refrigerant levels and cleaning outdoor units affected by local pollen and debris.

Our maintenance service includes comprehensive system checks: inspecting electrical connections, testing thermostat operation, cleaning coils and filters, lubricating moving parts, and checking refrigerant levels. For Novato homeowners, we pay special attention to blower motors and heat pump components prone to local wear. Regular maintenance helps prevent breakdowns, extends system life, and maintains energy efficiency—key for managing Marin County's temperature variations throughout the year.
