8 - 12. COD. Spoke to Lilia. SPC 137. They just moved in a little over a month ago, AC seemed to be working fine, but past 2 days they put thermostat to 60/62 and it was still really hot, not blowing cold air. She stood over vent yesterday and not blowing much. Doesn't know age but thinks it's under 10 years old. Quoted her $158 for the diagnostic.
