While an air conditioner is cycling, it makes a variety of noises. These sounds are part of normal mechanical processes involved in the movement of air and condensation of moisture. Understanding which noises are typical of an air conditioner's normal operations and which sounds are a cause for concern could alert you to a problem before the system has a complete breakdown.
Typical Air Conditioner SoundsCentral air conditioning systems contain a motor, fan, electronic controls, pressurized liquid that gets converted into gas and a drain pan that collects water. Depending on where the air conditioning is situated, it might seem noisy. If the outdoor unit is placed right next to a window or a wall with little or no insulation, most of the system's noise will be audible from inside the house. Normal sounds that you might hear during cycling of the air conditioning system include:
- A click or tick when the system starts a cycle.
- Whirring of the motor and fan as the system runs.
- Whooshing of air as it comes through the air ducts.
- Occasional popping from the air ducts, which is caused by the expansion and contraction of the sheet metal.
- Clicks or a thump as the system shuts down.
Abnormal Air Conditioner NoisesOnly a professional AC repair specialist can determine the cause of abnormal air conditioner noises. Abnormal system sounds include:
What To Do When an Air Conditioner Is Too NoisyIf an air conditioner suddenly makes more noise than usual, arrange for an air conditioner maintenance to troubleshoot and diagnose any problems. The HVAC technician will listen to several system cycles from inside and outside the house to determine if the noises are normal and within the expected range of loudness. The technician will repair any problems. After repairs are made, the unit may return to a more acceptable noise level. If there are no problems with the system, the noises it makes could just be the result of manufacturing constraints combined with the unit's location and the materials from which your house is built.
