Avoid in Downtown Miami
- Hiring a duct cleaner who doesn't ask whether you have central air, PTAC, or fan-coil — they're going to bring the wrong equipment.
- Continuous fan mode in PTAC units — accelerates wear on the only fan in the unit.
- Letting building managers tell you they 'just cleaned the system' without asking what specifically — usually they cleaned the lobby intake, not your unit.
- Cheap dryer-vent service that doesn't trace the line to the building riser termination — common shortcut downtown.
