Old A/C unit from 2002 no longer produces cold air. Prior to its inability to produce cold air, the unit couldn't keep the house cool during summer causing the unit to run all day non-stop. Unit outside also has a bad oscillating vibration creating a very loud noise inside. The house is a 1500+ sqft 2 story house. Single unit, with no splitter. One thermostat downstairs. I purchased the house March of 2017, there is no known information about prior service.
