Why is there a hissing noise in my room?
Hissing may be due to an internal relief valve, a refrigerant leak, or normal operation of an expansion valve. Something as simple as a bad fan start capacitor might be at the root of hissing noises at a heat pump or air conditioner compressor. Hissing may also be traced to an air duct leak.

The compressor hissing or shrieking is a serious situation: it means the pressure inside the compressor is too high.

Why does my toilet have a hissing sound?
A: Sorry to hear about your cacophonous commode, but the hissing you hear is a relatively common problem. It’s related to your toilet’s inlet water valve, also called a “fill valve.” Over time, hard water deposits or bits of sediment can settle in the valve and partially block water flow into the tank.
