What’s Included & What Affects Price
Every dehumidifier installation includes:
- Unit mounted in attic or utility room
- Ductwork tie-in to return air path
- Condensate drain line connection (to existing AC drain or dedicated)
- Electrical connection (dedicated 120V circuit if needed, +$199)
- Humidistat control (separate or integrated with thermostat)

Why Tampa homes need whole-home dehumidifiers:
- Summer humidity 80%+ — AC alone can’t pull below 55-60% unless running constantly
- Mold risk — anything above 55% indoor humidity = mold zone
- Dust mites — thrive above 55%, die below 50%
- Wood floors + furniture damage — Tampa humidity warps, rots over time
- Cooler-feeling air — dry 76°F feels better than humid 72°F, saves on bills
- Variable-speed AC limitations — even premium ACs struggle with coastal Tampa humidity
Factors that affect price:
- Home size + required pint capacity (70-pint, 90-pint, 130-pint)
- Attic access difficulty
- Dedicated electrical circuit needs
- Premium brand (Santa Fe, Ultra-Aire) vs standard (Aprilaire)
- Integration with smart thermostat (optional $599-$899 upgrade)
