Why DOE Ratings Matter for Montreal Basements
At Climate Solutions, serving the Greater Montreal area since 2013, we often get questions about the Department of Energy’s revised 2019 testing protocol for dehumidifiers. With our city’s damp basements and humid summers, understanding these adjustments can help you choose the right unit and optimize energy-efficient HVAC performance.
Evolution of DOE Testing Procedures
Back in 2012, the DOE evaluated dehumidifiers in a chamber set to roughly 27°C (80°F) at 60% relative humidity. After a full day of nonstop operation, manufacturers reported water removal as a pint rating—thus giving rise to the familiar 30-, 50-, and 70-pint categories.
Fast forward to 2019: the DOE opted for a more realistic scenario by lowering the test temperature to about 18°C (65°F) while keeping humidity at 60%. Climate Solutions’ latest dehumidifier models passed both tests, showing similar moisture removal but improved energy efficiency thanks to upgraded compressors.
Practical Takeaways for Homeowners
If your old “70-pint” machine performed under the former standard, it likely removes closer to 50 pints in cooler conditions typical of Montreal basements. When you purchase our new 50-pint model, you’ll still get high output in warmer, more humid spaces—plus savings on your Hydro-Québec bill.
Tip: Position your dehumidifier away from walls to improve airflow. For continuous drainage, use a gravity line or built-in pump. And remember, maintaining indoor humidity around 50% helps prevent mold growth during our cold winters.
Frequently Asked Questions
1. Why does a smaller pint number cost more?
It isn’t physically smaller—only the test conditions changed. Newer units are optimized for cooler, real-world settings, so pricing reflects upgraded, energy-saving components.
2. Do I still need a “70-pint” unit?
Even our 50-pint model can outperform older 70-pint machines if your space runs warmer or more humid than 18°C/65% RH. We tailor HVAC maintenance Montréal packages to ensure you get the right capacity.
3. Should I discard my old dehumidifier?
Not necessarily. If it’s in good working order, you can continue using it. But for optimal energy-efficient HVAC Montréal performance, upgrading could lower your operating costs.
