Condo is in Florida. The building is 32 years old. 8 Units in a 2story building. Mine is on the 2nd floor. Brand new HVAC system including ducts-2018.
Attic insulation was fine according to a home inspector in 2018, but some "bare" spots were remediated in 2019 through weatherization assistance program. Humidity is maintained 50-60. Temp is set 74-77F.
No leaks, no visible mold anywhere. Walls are clean and painted in 2017 before selling. No old furniture. No carpet. Large windows, plenty of day light. Mix of cathedral ceiling and normal ceiling in bedrooms. Washer and Dryer are on Lanai (outside). No pets.
I live there year around. I am very sensitive to odors. When I walk in from outside, the old house odor is clearly felt. It is not very strong, but I sense it.
Any ideas on where it may be coming from?
