“As a construction guy, please please PLEASE check the attic. People buy houses and never check the actual AC. If you go up there and smell a burnt smell, or see big silvery tubes that look crumpled, those are issues. I do HVAC. A burnt smell in the attic means both a compressor issue (caused by never changing the filter) and the silvery tubes are called flex, which acts as ductwork. If they look bent, don’t buy.”
