Anyone here familiar with Amana ARHF30U01A condensing unit?
1. Mine is at least 13 yrs old maybe 15. Never been serviced (owners man. says fan motor should be oiled). Is this known as a long lasting unit or have I been lucky. It's matched with another brand of air handler twice as old. Still cooling fine though not efficiently. Is it living on borrowed time. Maybe some of you have worked with this.
2. Do compressor failures give warning symptoms or do they just cool one day and die the next ?
