The answer to 'inspection making noise' is that there are several common causes for an HVAC system making noise during an inspection. This could be due to worn or loose components, debris buildup, or issues with the blower or compressor. Symptoms may include rattling, banging, or high-pitched squealing sounds.
In many cases, the solution may be as simple as cleaning or tightening components. However, more serious issues like a failing compressor or motor may require professional repair. It's important to address any unusual noises promptly to prevent further damage and ensure the system is operating safely and efficiently.
