If you’re hearing a loud hissing noise coming from your AC unit, the problem could be related to a refrigerant line leak.

Refrigerant leaks can happen for a variety of reasons, and resolving the issue depends on the location and cause. For example, the issue could be:

  • the condenser coils leaking the refrigerant

If the loud noise coming from your AC is due to a refrigerant leak, it’s important to consult your HVAC professional because you could end up doing more damage if you ignore the problem or attempt to fix it on your own.

Why is my AC unit making a loud noise? The answer could be debris. If it sounds like there’s a lot of internal clattering, some type of debris could be lodged inside your AC unit.

If a bolt or screw came loose within your unit, it could have been blown into the wrong place. Your unit will need to be thoroughly inspected in this case to identify what type of debris is lodged inside your unit and how to safely remove it and fix any damage it caused.

Your HVAC technician can conduct a pressure test to identify if your ductwork was improperly installed.

A loud squeaking noise from your AC unit usually is because your fan belt has come loose. That could mean it simply needs to be repositioned, or it could have broken and need to be replaced.
