Air Conditioner makes Loud Hum when starts then goes away
I am a new home owner and I am starting to understand why my Dad got
frustrated all those years when something broke in the house. I have just bought a townhome here in Houston. The compressor units are mounted on the roof. When the AC starts, there is a loud humming noise (i assume it is the compressor starting up) for about 15 seconds and then it drowns out. It cools fine and works great other than the noise. My neighbor is complaining to me saying it creates to much noise. What causes this loud hum when it starts? I know that there is always going to be some kind of hum, when it starts, but this is out of the ordinary. Any suggestions or tips are appreciated. Thanks. Joseph |

Joseph Some compressors are just a little bit noisier than others, even among specimens of the same model. Or it could be vibration in the lines. It damps out as headpressure builds up. If so, something up there could be missing or broken. It even could be a problem with the installation, and can still be fixed, but will probably require opening the system, and that requires a pro... If it's an older townhome, maybe the neighbors got nowhere complaining to the previous owner, but now that you moved in... food for thought... -----BEGIN PGP SIGNATURE----- Version: PGP 7.1 iQA/AwUBQucevgIk7T39FC4ZEQKriwCfb1Aw2peTxVyX2jvzPzvYL/SWHi8AoPn5 Q3NBQbvpq6ZqF4EpSeq8hXcn =opaD -----END PGP SIGNATURE----- -- -john wide-open at throttle dot info |

I'm not sure what you mean. Drowns out what? AFAIK, "drowns out" must be followed by another noise. The first noise is louder than the second and drowns the second noise out so that the second noise can't be heard. Maybe you mean it fades out? It cools fine and works great other than the noise.

It happened to me when the idiot A/C guy over charged the system. Get a pro
to check it out. IF that is the case, eventually the compressor will die causing a much bigger repair bill. As far as I could tell the idiot did not compensate for ambient temperature when he filled the system during the last service call (it was a cold day). "J-Man" wrote in message ups.com...

The First loud hum fades out to a low hum.
