Hi - we have a typical home AC system - ours is a Ruud - the model number on the outside unit is UAKA- 037JAZ. It's been very hot here in Texas - over
100 all day long, but the system is working OK and cooling the house - plenty of cool air coming out of all the vents - the AC runs a lot these days, but it always has when it's very hot outside since we've lived here - I guess that's because it's an older unit (1996) and not as efficient as some of the newer units. The filter has always been changed regularly.For several months now, I'm hearing a loud buzzing noise from the outside unit when it's running - the fan spins OK and there's hot air coming off of the unit - the noise is nothing that keeps us awake at night, but certainly noiser than my neighbor's units - they were replaced within the past few years and they're newer.
Is this kind of noise typical of the older units?? If not, what am I likely to hear is the main problem from the AC repair guy if the unit goes out and I need to make a repair call?
I had something on the outside unity replaced a few years ago - I think it was the start capacitor.
Thanks!
