The answer to 'installation making noise' is that there are several common causes, including loose components, worn bearings, or a problem with the air ducts. Symptoms may include rattling, banging, or whistling noises coming from the HVAC system. Solutions can range from simple tightening or lubrication to more complex duct work or component replacements.
If the noise is mild and intermittent, some basic troubleshooting and DIY fixes may be possible. However, if the noise is persistent, loud, or accompanied by other issues like poor airflow or strange smells, it's best to call in a professional HVAC technician to diagnose and repair the problem. Attempting complex repairs without the proper training and equipment can often make the issue worse or even create safety hazards.
