If your new air conditioning (AC) unit is excessively loud inside your house, there could be several reasons for this issue. Here’s a guide to help you troubleshoot and address the problem:

Why is My New AC so Loud Inside my House?

here are different reasons

Improper Installation

    • Ensure that the AC unit was installed correctly by a professional. Improper installation can lead to vibrations and noise.
    • Check if the unit is securely mounted on the wall or window and that there are no loose components.

Wrong Size of AC Unit

    • An AC unit that is too large for the space may cycle on and off frequently, causing noise. Conversely, a unit that is too small may run continuously, also leading to increased noise levels.
    • Confirm that the size of the AC unit matches the recommended capacity for your room.

Dirty or Clogged Air Filters

    • Dirty or clogged air filters can restrict airflow, making the AC work harder and produce more noise.
    • Regularly clean or replace air filters according to the manufacturer’s recommendations.

Loose or Damaged Parts

    • Inspect the AC unit for loose or damaged components, such as fan blades, motor mounts, or ductwork.
    • Tighten any loose screws or bolts, and replace any damaged parts.

Vibrations and Noise Transmission

    • Vibrations from the AC unit can transfer noise to the structure of your house. Consider using vibration isolators or noise-reducing pads to minimize this transmission.

Inadequate Insulation

    • Check the insulation around the unit and the walls. Proper insulation can help reduce noise transmission.
    • Consider adding insulation around the AC unit or in the walls if necessary.

Fan Issues

    • The fan motor or blades may be causing excessive noise. Check for any obstructions or debris in the fan assembly.
    • Lubricate the fan motor according to the manufacturer’s recommendations.

Ductwork Issues

    • Inspect the ductwork for any leaks, loose connections, or damage. Leaky ducts can contribute to noise inside the house.
    • Seal any gaps or leaks in the ductwork.

Manufacturer Support

    • If the noise issue persists, contact the manufacturer’s customer support or the installation technician for assistance. They may provide guidance or recommend a service visit to diagnose and resolve the problem.

If you are unable to identify or resolve the issue on your own, it’s advisable to seek professional help to ensure the proper functioning and quiet operation of your AC unit.
