Why is My AC Making Strange Noises?

Buzzing, hissing, or banging: discover what your unit's noises mean and when to call a technician.

Hissing or Whistling

These usually indicate a refrigerant gas leak or high pressure in the compressor. It's a serious issue requiring immediate attention.

Electrical Buzzing

A loud buzz from the outdoor unit often means the capacitor or fan motor is failing. If you hear this, turn off the unit and request air conditioning repair in Mijas to prevent major compressor damage.
