It started two weeks ago at night I heard the sudden buzzing sound from outside and got scared and turned off outside unit. The noise went away. After 10 to 15 minutes I turned it back on and I haven't heard this noise for two weeks.
Tonight, it did again. Instead of turning off, I went out to see. It seemed the air from condensor is not hot. I guess it means a/c is not running (?). I turned off again and the noise went away. obviously fan is running.
It's long holiday and I want to know if that's something I need to be really worried. I didn't get a tune up this year since my indoor coil was replace in Sepetember and didn't think I needed a tune up.
Is it somehing I should really worry and compressor going bad?
what's the really symptoms of a compressor going bad. I noticed my next a/c is making a simliar noise tonight but less noisy. I didn't dare to go to my next door's and check it out.
It's 3 ton split unit in Dallas, Texas. it's bryant and 10 years old. It was just the coil replaced last year. Condensor is 10 years old.
