Air Conditioner Making Noise After Shutting Down, The Reason

There can be several reasons responsible for your air conditioner making noise immediately after turning it off. The noise can be frightening. Determining the specific cause of this noise can be difficult, especially if you are not consulting a licensed and qualified air conditioning (AC) repair company like Reef Air Conditioning to diagnose your AC unit. However, there are quite a few general causes that can assist you to know if you need the services of a licensed and qualified AC repairer.

Air Conditioner and its Major Components

From our experience at Reef Air Conditioning, installing, repairing, and maintaining air conditioning systems; there is a need to understand the major components of an air conditioning unit, and how these components operate, before looking into the reasons for your air conditioner making noise every time it is turned off. Reef Air Conditioning provides exceptional air conditioning services that our customers can trust and rely on.

Below are some of the main components of your air conditioner unit that you can physically identify.

  • Air Filter: The Air filter helps to remove airborne particulates and contaminants such as dirt and dust, from the air supply to your home that could affect your health and comfort. It cleans the air that is circulated through the air conditioner system. The air filter should be replaced quarterly.
  • Air Blower and Handler: The air handler and blower operate jointly to take in air to the evaporator from inside of your home. This air intake is circulated all over the entire house.
  • Evaporator: The evaporator of an air conditioner receives the liquid refrigerant and converts the refrigerant into gas. This gas works to dehumidify and cool the indoor air. The evaporator is usually situated in an area of the air conditioning unit that is cold.
  • Condenser: The condenser is located in the area of the air conditioner that is hot. It complements the evaporator. The condenser condenses the gaseous and vaporized refrigerant and ejects heat to the outside of your home. This process converts the vaporized refrigerant back into a liquid refrigerant.
  • Compressor: The compressor is responsible for converting the gaseous refrigerant under high pressure back into the liquid refrigerant. The compressor works together with the condenser. It is situated in the hot area of your or conditioning unit.
  • Expansion Valve: The expansion valve is situated between the evaporator and the condenser. It regulates the quantity of liquid refrigerant that follows the evaporator.

These four main components of your air conditioning unit are critical to you understanding the reason for your air conditioner making noise. They help you to identify the reason for the whacking sounds that are heard when you turn off your AC unit.

Below are some of the reasons responsible for the loud sound you hear when your air conditioner is turned off. They can cause the malfunctioning of your AC main components discussed earlier and the loud noise heard from your AC unit components. The noise can originate from any of these major components.

Does the Noise Originate from Inside?

  • An air filter that is dirty, obstructive, or has a return duct that is tiny maybe knocking against the grille.
  • Some AC units have dampers that alter the quantity of airflow that circulated to various areas of the home. The knocking or slamming sound heard resulting in your air conditioner making noise might be as a result of the damper closed when the AC unit is turned off.
  • The ductwork that is contracting or expanding might also produce a slamming or knocking sound that can be responsible for your air conditioner making noise when the AC unit is powered off.
  • There might also be a problem with your AC unit’s air handler that is making the wheel of the blower hit against other components inside the AC unit.

Does the Noise originate from Outside?

  • The support spring of your compressor might have exhausted its lifespan. This will make the spring to be imbalanced, causing the refrigerant pump to slam against the compressor’s chassis.
  • There might be a need for the fan in the outdoor unit of your AC unit to be replaced or repaired. Loose components can result in your air conditioner making noise.
