Hello all,
I recently noticed that the a/c condensing unit at my townhouse makes a noise, intermittently, as it's running. The noise itself is hard to describe, but I'd say it's similar to the hum of a transformer, but a bit more pronounced, if that makes sense. Anyway, the noise will show itself, last about 5 - 10 seconds and fade away, only to reappear within seconds to a minute or so again later. This happens throughout the cooling cycle. I put my meter on it, and it steadily draws 6.5 amps, whether it's making this noise or running quietly. This unit is 13 years old and appears to be functioning properly otherwise. The specs on the compressor are 14.1 RLA and is rated for 208 - 230v. However, at the time of testing, the supplied voltage was 245v. I'm not sure if this is a dire situation or I can let it be. I just want to address this in an effort to both quiet it down and increase it's life expectancy. I did change the cap, but it didn't do the trick. Thanks!
