Precision HVAC & IAQ for Park Slope Family Townhomes​
​
Climate Control Designed for the Modern Park Slope Family Life in Park Slope revolves around the park, the schools, and the home. When your multi-story brownstone has "hot spots" on the top floor or poor air quality, it impacts your family's quality of life. Dezier Air provides "Human-Centric" HVAC solutions that prioritize quiet operation, air purity, and floor-by-floor comfort.​

​
Solving the "Park Slope Comfort Gap"
​
Many Park Slope brownstones suffer from the "Chimney Effect"—where heat rises rapidly through the central stairwell, leaving the garden level freezing while the top floor is sweltering. Dezier Air specializes in balancing these vertical homes. As a Mitsubishi Diamond Dealer, we don't just "install AC"; we engineer multi-zone solutions that ensure your nursery on the 4th floor is the same temperature as your kitchen on the garden level.

Frequently Asked Questions
​
What is the best HVAC system for a multi-story brownstone in Park Slope?​
​
For Park Slope families, a Multi-Zone Heat Pump system is the gold standard. It allows you to set different temperatures for each floor—ensuring bedrooms stay cool while living areas remain comfortable—without the massive energy waste of a single-zone system. Dezier Air specializes in "no-demo" installations that preserve your brownstone’s historic detail while providing modern, filtered air.
​
What are the most common HVAC issues in Park Slope brownstones?
The three most common issues are uneven heating between floors, dry air from aging steam systems, and high energy bills due to lack of insulation in historic masonry. Dezier Air solves these with multi-zone VRF technology and "Surgical HVAC" retrofits that add modern efficiency without needing to gut your historic plaster walls.
​
How can I improve air quality in my Brooklyn home?
In 2026, the gold standard for Brooklyn air quality is a combination of MERV-13 filtration and Active Carbon scrubbing to remove odors and VOCs. Dezier Air integrates these directly into your central system, providing a "hospital-grade" environment that is essential for homes near heavy traffic corridors like 4th Avenue.
