Unusual noise is one of the most obvious signs that your air source heat pump needs maintenance. Even though these systems usually run quietly, any unexpected whistling, rattling, or banging noises should cause concern. These sounds could indicate problems with the compressor or fan, loose parts, or refrigerant leaks. By taking quick care of these noises, minor problems can be avoided before they become more serious and require repairs.
