Honeywell Energy Star A90D 90 Pint Whole House Dehumidifier

The reliable Honeywell Energy Star A90D 90 Pint Whole House Dehumidifier is a professional-grade solution designed for long-term moisture control to keep large residences comfortably dry. Purpose-built for ducted or stand-alone applications, it integrates seamlessly with existing HVAC systems to help you maintain balanced humidity throughout every conditioned room.

Behind its compact cabinet is Honeywell’s latest air-management technology, refined through rigorous life-cycle testing, that delivers reliable moisture control with minimal energy draw. With its smart onboard sensors, tri-directional outlet for versatile placement, and replaceable components, the A90D is built to deliver consistent performance.

Key Features and Benefits of Honeywell 90 Pint Whole-House Dehumidifier

• Simple Controls: The onboard digital controller can be placed anywhere on the dehumidifier, with its tethered and magnetic mounting options, helping you to view dehumidifier status and alerts, track operational history, and adjust ventilation and target humidity range.
• High Capacity: Removes up to 90 pints per day in spaces up to 5,000 square feet.
• Energy Star Certification: The A90D operates at 2.49 liters per kilowatt-hour, lowering operating costs through optimized refrigeration and airflow, saving energy season after season.
• Tri-Directional Outlet: Offers left, right, or vertical discharge options, letting you run ductwork in tight spaces. Install 10-inch round ducting on the inlet and outlet and 6-inch round ducting to the vent inlet for proper installation.
• Integrated Smart Sensors: Continuously track temperature, relative humidity, differential pressure, and potential water leaks in real time, giving you data-driven insight for preventive maintenance.
• Easily Serviceable Design: The modular wiring design allows for easy replacements of core parts, including the motor, blower wheel, and control board, instead of replacing the entire cabinet to reduce downtime and long-term service expenses.
• Built-In Ventilation: Supplies up to 370 CFM of fresh air to help meet local building codes without adding a separate ventilator.
• Standard MERV 8 Filter: The standard 14 x 20 x 1-inch filter captures common airborne particles, preventing them from reentering your home's air.
• Operating Temperatures: Its 20-gauge galvanized steel powder-coated cabinet, sealed electronics, and a high-efficiency rotary compressor stand up to  temperature swings down to 34 degrees F and up to 130 degrees F.
• Water Leak Detection: The L-series water leak detector cable works as an auxiliary detector to notify and automatically shut off the dehumidifier when a leak is detected.

Engineered To Last

From the powder-coated steel shell to the corrosion-resistant internal coil, every component is built for longevity in real-world conditions. Honeywell’s exhaustive life-cycle testing of 150,000 hours of runtime simulates decades of use and verifies that airflow, dehumidification rate, and calibration remain steady over time. Combined with tool-free access panels and intuitive wiring blocks, these safeguards translate into faster installations and reduced maintenance budgets.
