2 ton Ruud condenser with Copeland Scroll compressor. House is nice and cool and humidity runs between 35-40%. It had no problem keeping the house at 72 when we had a 95 degree day.
Compressor is noisy and makes a humming type noise that comes and goes but mostly its there. Im concerned because my Scroll compressor is noisier than both my neighbors old reciprocating compressors. I can hear it quite loud in the bathroom where I could barely hear the fan air on the 18 year old Ruud unit it replaced.
Any ideas??? Ive had 2 brain dead techs look at it and find nothing wrong.
could it be due to very slight kinks in lineset?
over or under charge?
could .059 orifice had been damaged during brazing?
could brazing without nitrogen have been a factor?
any suggestions on competent techs in Chesapeake Virginia area?
