Performed maintenance on ICP system installed in 2022 just prior to client moving into the condo. Upon arrival a foul smoke odor emitted from the ductwork was brought to my attention and the client had interest in his ductwork being replaced. The condo is on the first floor of a two story condo building with no attic access and ductwork is all ductboard which cannot be cleaned. The previous resident smoked tobacco inside creating the issue. Cleared drain line and replaced air filter. Applied deodorizer on indoor coils as a temporary solution. Electrical components and refrigerant levels good at this time. Replaced AAA batteries in thermostat. System running well upon departure.. Collected 49 with Visa. Job complete.,,
