Living area
What you see in the basement
It's the right size.
For a 2,200 to 2,800 sq ft home with condensation on the walls or windows, you need to remove about 102 pints a day (spec sheet conditions). It removes 120: enough for the house, with some reserve for humid weeks in July.
Calculation: pints a day needed for the living area and the basement's condition, at the spec sheet's test conditions. Our estimator measures the humidity on site before ordering.
What it does, in numbers
$134
Electricity per year
8 h of running a day, May to October
Same calculation for every line: wattage × running hours × 184 days (May to October) × 11.142 ¢/kWh. The unit stops on its own once the target humidity is reached, so its running hours depend on your basement.
Capacities, efficiency and electrical data: manufacturer's spec sheet. Running wattage calculated: litres per day ÷ litres per kWh ÷ 24 h. Cost: Hydro-Québec Rate D, second tier (11.142 ¢/kWh), in effect since April 1, 2026.
What you should know about this one
Published, verifiable facts, not brochure claims.
WallA humidity control to plan for
It has no built-in humidistat. It runs from an external control sold separately, such as the HumidiPRO H6062A1000 or a Prestige IAQ or VisionPRO thermostat. Our estimator includes it in the quote.
400 cfmThe highest airflow of the TrueDRY line
The spec sheet gives 400 cfm with no ducts and 295 cfm at 0.4 in. of static pressure.
20.5 inThe DR90's footprint, 30 more pints
Same length (25.88 in.) and width (14.75 in.) as the DR90; only the height changes, 20.5 in. instead of 19.88. Yet it removes 30 more pints a day at 80 °F.
6 inIt can ventilate too
6 in. fresh-air inlet with a separate ventilation control. Resideo offers the EARD6 motorized damper and the SPRD10 10 in. backdraft damper as accessories.
120 → 63What it really removes in a basement
120 pints a day at 80 °F, 88 at 70 °F and 63 at 60 °F, always at 60% humidity: those are the numbers on the manufacturer's spec sheet. The cooler the air, the less it removes. Most sellers only show the first number.
2.9 LWhat it removes per kWh
Each kilowatt-hour removes 2.9 litres of water from the air. At Hydro-Québec's Rate D, that's about 3.8 ¢ per litre.
40–60%The humidity range to aim for
The range recommended by ASHRAE. Above 60%, a home becomes prone to mold and mildew.
1 °CIt works in a cold basement
Operating range of 1.1 to 57.2 °C per the spec sheet: it keeps working in spring and fall, when the basement is still cool and damp.
MERV 11The filter
Filter: MERV 11, 14 × 17.5 × 1.75 in. It protects the coil and captures part of the particles in the basement air.
5 yrsThe parts warranty
Manufacturer's limited warranty on parts.
What it needs on site
In a finished basement, we put it in the mechanical room and connect it with ducts to keep the noise away from living spaces. Our estimator checks the location, the drain and the duct route before ordering.

The Ultimate Guide to Honeywell's DR120A3000 Dehumidifier
At AirGreen, we pride ourselves on being the leading HVAC service provider in Montreal, Laval, Longueuil, North Shore, and South Shore. Our commitment to quality and innovation is evident in every product we endorse. Today, we're thrilled to introduce you to the Honeywell DR120A3000 Dehumidifier - a game-changer in home comfort.
Why Choose the Honeywell DR120A3000?
The modern home is a marvel of energy efficiency. However, this efficiency often comes at the cost of indoor air quality. With homes being built tighter than ever, there's limited natural exchange between indoor and outdoor air, leading to excessive humidity trapped inside. This is where the Honeywell DR120A3000 steps in.
Key Features:
-
High Capacity: With a dehumidifying capacity of 120 pints per day (that's a whopping 57 liters!), this unit is designed to handle the needs of larger homes up to 3500 sq. ft. in size.
-
Energy Efficiency: The DR120A3000 removes 2.9 liters of water per kWh per the spec sheet, which keeps its impact on your electricity bill in check.
-
Quiet Operation: Nobody likes a noisy appliance. With a sound level of less than or equal to 74 A unducted at 1 foot from the appliance, this dehumidifier ensures your home remains a peaceful haven.
-
Advanced Filtration: The MERV 11 rating means that the air in your home will not only be drier but also cleaner. Say goodbye to allergens and hello to fresh, clean air.
-
Easy Maintenance: The automatic draining feature means you won't have to constantly empty out water trays. Additionally, the air filter only needs to be changed once a year, making upkeep a breeze.
The Science Behind the System
The Honeywell DR120A3000 uses a combination of refrigeration and internal air circulation to cool the incoming air below its dew point. As the air cools, water condenses and drains off the coil, resulting in drier air being circulated back into your home. This process not only reduces humidity but also ensures that the air you breathe is fresh and clean.
Benefits of Whole Home Dehumidification
While portable, single-room dehumidifiers have their place, nothing beats the efficiency and effectiveness of a whole-home system. Here's why:
-
Comprehensive Coverage: Unlike portable units that only dehumidify the room they're in, a whole-home system ensures consistent humidity levels throughout your home.
-
Cost-Effective: Integrating the dehumidifier with your HVAC system can be more economical than running multiple single-room units.
-
Environmentally Friendly: The DR120A3000 uses the eco-friendly R-410A refrigerant and meets all EPA standards for refrigerants. Plus, with a 5-year warranty, you can rest easy knowing you've made a sound investment.
In Conclusion
When it comes to ensuring the comfort and health of your home, don't compromise. The Honeywell DR120A3000 Dehumidifier offers unparalleled performance, energy efficiency, and ease of use. At AirGreen, we're proud to offer this state-of-the-art solution to our valued customers in Montreal and the surrounding areas. Experience the difference today.
