Compressor of the Ruud A/C outside unit is making unusal loud continuous noise. I open the case, its not the fan or fan motor, loud noise is coming from the compressor, and it is also heating up a lot. Please let me know what my options are. Thanks.

Heat pump is 10 years old. No vibration sound in A/C mode. Loud 60 cps vibration sound in house near compressor when compressor is on. Compressor is not making a lot of noise when I open up the outdoor unit and put my hand on it. All compressor rubber mounts are tight and not broken. Looked for vibrations in copper tubing in the basement from the outdoor wall to the indoor unit. It is vibrating but seems loudest by the compressor. How can I isolate the source of noise?


Hi,\015\012\015\012\015\012Overcharged ? that's a possibility but also the vibration could be originating inside the heat pump - either at the main contactor or at the reversing valve ,or like I mentioned simply vibrating against the wood where ... Air Conditioners

Loud noise after compressor shut off


... Air Conditioners

We have a 2000 Winnebago Adventurer with basement air, "true air". Yesterday our AC unit started making a loud buzzing noise about every 90 seconds. Like maybe the second compressor was trying to start up and couldn't. We turned the AC off for awhile, and when we started it up again the noise started immediately. It buzzes for maybe 10 seconds. What can we try ? Should we leave it turned off ? It is over 100 degrees here in Texas and we need help fast!!! Thank you. Pam

9/13/10- Our air conditioner makes a loud noise every time it goes on-enough to keep us awake at night. We have had your representatives in to look at it as well as the people who installed the system in 2006. There seems to be a conflict of opinions. One says I need a compressor, the other says I don't. They also suggested that I wait until the compressor dies to do something. In the meantime, no one has done anything or offered a solution for months now. If they keep me waiting long enough,

I have an Amana PTAC that was just installed two weeks ago. I am starting hear a moderately loud warbling sound when it is in operation but not all the time. It's loud enough to wake me up in the next room. Sounds like an unlevel washing machine. I turned the unit off then back on and it does it again. Other times it goes all day without making this noise. I'm sure it does this when I'm away and I never know. This is only when the heat is on. Could the AC compressor be kicking on? If so, that's

My central air conditioner is making a whistling noise in the inside unit when the compressor is running. It's not the blower because the noise stops after the outdoor unit shuts off. It's also not blowing any cold air and the piping is not getting cold. What could be the possible cause?
