Sound Recordings of A/C & Heat Pump System Noises
Sound & video recordings of air conditioning & heat pump compressor noises are provided & discussed here.
This noise and the reader's video were originally reported in the FAQs at HVAC NOISE Group 5
where we discuss
SCREAMING HVAC EQUIPMENT or whistling or shrieking A/C compressor/condenser unit sounds - warning about high pitched sound from the compressor/condenser unit !
Possible causes of this screaming noise: we, like Jeremy, think this may be a bad blower bearing
Watch out: turn off a screaming air conditioner or heat pump. The cause could also be dangerously high refrigerant pressures.
Some techs think screaming sounds may be a refrigerant leak but in my experience if there's a refrigerant leak lound enough for you to hear it it will be a hissing sound, and also it won't last long since your system is going to lose all of its refrigerant (and stop working) in minutes.
