Honeywell Energy Star A120D 120 Pint Whole House Dehumidifier

Engineered for reliability, the Honeywell Energy Star A120D 120 Pint Whole House Dehumidifier delivers continuous humidity control in your home. By integrating dehumidification and fresh-air ventilation into one streamlined package, it helps you safeguard against problems from excess moisture like mold, mildew or musty odors, and maintain optimal indoor comfort year-round.

This high-capacity system connects to new or existing ductwork, quietly drawing moist air from every room and returning drier, conditioned air through a tri-directional outlet. Its robust internal sensors, field-serviceable components, and Energy Star–qualified performance give you an efficient, reliable solution.

Key Features and Benefits of Honeywell Energy Star 120 Pint Dehumidifier

• High Capacity Moisture Removal: Pulls up to 120 pints of excess moisutre from the air every day so you can tackle heavy to maintain your perfect 0 to 95 percent relative humidity (RH) range.
• Simple Controls: The onboard digital controller provides a simple hub to view dehumidifier status and alerts, track operational history, and adjust ventilation and target humidity range. Place the onboard controller anywhere on the dehumidifier with its tethered and magnetic mounting options.
• Built-In Ventilation: The rotary compressor automatically turns on or off to bring in a measured amount of outside air to dilute indoor pollutants while dehumidifying, reducing the need for a separate ventilator and simplifying system design. It is capable of bringing an airflow up to 370 CFM at 0.0-inch WC without any dampers.
• Tri-Directional Outlet: Choose left, right, or vertical discharge to fit tight mechanical rooms, ceiling cavities, or basement installs without extra duct transitions using 10-inch round inlet and outlet ducting and 6-inch round vent inlet ducting.
• Intuitive Sensors: Monitor temperature, relative humidity, airflow, pressure, water leakage, and more in real time, ensuring consistent performance even when ambient conditions fluctuate.
• 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.
• Standard Filtration: A standard 20 x 14 x 1-inch MERV 8 filter captures dust and debris before they reach internal coils, extending equipment life.
• Operating Temperatures: Its 20-gauge galvanized steel powder-coated cabinet, sealed electronics, and a high-efficiency rotary compressor stand up  to temperature swings from 34 degrees F up to 130 degrees F.
• Energy Star Certified: Operating at 2.41 liters per kilowatt hour at 73 degrees F, 60 percent relative humidity, and 0.2-inch WC, the A120D whole-house dehumidifier meets strict efficiency guidelines so you can efficiently maintain dryness.

Service-Ready Design

With replaceable components, the Honeywell A120D is equipped to make maintenance and servicing easy with tool-less access panels, front-mounted diagnostics, and modular wiring harnesses. This allows technicians to isolate issues quickly, and swap only the failed part to return the system to service in a single visit.
