If you live in Florida — especially Southwest Florida — your air conditioner alone cannot control indoor humidity. Here's why a whole-house dehumidifier is essential, which models to consider, and where to buy one.
Why Your AC Isn't Enough
Air conditioners remove some moisture as a byproduct of cooling, but they're not designed as dehumidifiers. In Florida's subtropical climate, indoor humidity often stays above 60–65% even with the AC running constantly. The EPA recommends keeping indoor humidity between 30–50% to prevent mold, mildew, dust mites, and structural damage.

How Much Does a Whole-House Dehumidifier Cost?
At Furnace Direct, whole-house dehumidifiers start around $2,179 for the Aprilaire E070 and go up to $3,292 for the E130. These are factory-direct prices — typically competitive with or below Amazon and Sylvane pricing, with the added benefit of expert HVAC sizing guidance included.
Installation
Whole-house dehumidifiers can be installed as standalone units (in a basement, crawl space, or utility closet) or ducted into your existing HVAC system. Most homeowners can install a standalone unit themselves with basic tools. Ducted installations should be done by an HVAC professional.
