Avoid in Miami Beach
- Buying a window unit instead of servicing your central system — Beach building rules often prohibit visible window units.
- Booking duct cleaning the day before guests check in — give the unit 24 hours to fully dry before turnover.
- Skipping coil cleaning because 'the tech said it looked fine' — visual inspection misses biofilm.
- Letting STR cleaning crews change filters — they almost always install the wrong MERV.
