[A/S] AC question, humming, Armstrong
Greetings All:
My AC unit is an Armstrong "1971 31' Excella"
When plugged into a 15 amp circut (not trying to using the AC) there
is a hum from the unit. If its cool out the hum goes away but if its
warm we have the hum.
Is this anything to worry about? or is it just a 31 year old ac unit
Thanks
