Why Is My A/C So Loud?

June 3, 2024 | Blog

Living in New Orleans, Kenner, Jefferson, Metairie, and Chalmette means relying heavily on your air conditioning system to stay cool and comfortable. If your air conditioning system is making loud or unusual noises, it’s essential to identify the cause and address it promptly. Surgi’s Heating, Cooling, Electrical, & Plumbing is here to help you understand why your A/C might be loud and what you can do about it.

1. Loose or Broken Parts

Rattling or banging noises could indicate loose or broken parts within the unit, such as screws, bolts, or fan blades. Ignoring these sounds can lead to more significant damage. Contact Surgi’s Heating, Cooling, Electrical, & Plumbing at (504) 215-7421 for a professional inspection and repair.

Expert Tip: Regularly check and tighten any accessible screws and bolts on your A/C unit to prevent parts from becoming loose.

2. Refrigerant Leaks

A hissing or bubbling sound may signal a refrigerant leak. Low refrigerant levels can impair your system’s performance and cause additional problems. It’s crucial to have a professional check for leaks and recharge the refrigerant as needed.

Expert Tip: Have your refrigerant levels checked annually to ensure optimal performance and early leak detection.

3. Fan or Motor Issues

Grinding or squealing noises often indicate problems with the fan or motor, such as worn-out bearings or belts. These components are vital for your system’s operation, and prompt repairs can prevent a complete breakdown.

Expert Tip: Lubricate the motor bearings regularly and replace worn-out belts to keep the fan and motor running smoothly.

4. Ductwork Problems

Whistling or buzzing sounds can result from issues within your ductwork, such as leaks, blockages, or poorly sealed joints. Efficient airflow is essential for optimal cooling, so it’s important to address ductwork problems quickly.

Expert Tip: Inspect your ductwork for visible leaks or damage and seal them with duct tape or mastic sealant to improve airflow and efficiency.

5. Debris in the Unit

Leaves, twigs, and other debris can find their way into your outdoor unit, causing strange noises and reducing efficiency. Regular cleaning and maintenance can keep your unit free of debris and running smoothly.

Expert Tip: Clear the area around your outdoor unit regularly and consider installing a cover to protect it from debris.

Very professional!

The technician, Rene, was very thorough and informative. He called before he was arriving to let me know when he would be there. It was in the window of time Surgis gave me. I will definitely use them for regular maintenance and future HVAC needs. Very professional!
