Brooklyn's neighborhoods are as diverse as its building stock. From the landmark brownstones of Park Slope and Bed-Stuy to new construction towers in Downtown Brooklyn and Williamsburg, every block has different HVAC needs.
We serve residential and commercial clients across all of Brooklyn. Brownstone owners call us for boiler service and ductless cooling. New condo developers bring us in for full mechanical design. Restaurant owners in neighborhoods like Bushwick and Williamsburg rely on us for kitchen ventilation.

Common HVAC Challenges in Brooklyn
Brownstone Heating Systems
Brooklyn brownstones typically have old boilers — many original cast iron units from the early 1900s. These need regular maintenance, and when it's time to replace, a high-efficiency condensing boiler can cut fuel bills significantly.
Adding AC Without Ductwork
Most brownstones and older apartments have no ductwork. Mini-splits are the standard solution — wall-mounted heads in each room, connected to one outdoor condenser.
Radiator Balancing
Uneven heat is the #1 complaint in older Brooklyn buildings. Some rooms are 85 degrees while others barely get warm. Proper balancing of steam traps, air vents, and zone valves fixes this.
New Construction Mechanical
Brooklyn's development boom means new buildings need full HVAC design from scratch — load calculations, equipment selection, ductwork layout, and code-compliant installation.

Brooklyn HVAC — Frequently Asked Questions
Can I add central air to my Brooklyn brownstone if it has no ductwork?
Most brownstones and prewar Brooklyn apartments were never built with ductwork, so full central air usually isn't practical without major construction. Ductless mini-splits are the standard solution — wall-mounted heads in each room connected to one outdoor condenser, with no need to open up walls and ceilings for duct runs.
Some radiators in my prewar Brooklyn apartment are scorching while others stay cold — can you fix that?
Yes. Uneven heat is the number-one complaint in older Brooklyn buildings. In steam systems it's usually failed steam traps or clogged air vents; in hot-water systems it's often air locks or a stuck zone valve. Balancing the system — rather than cranking the boiler — is what actually evens out the temperature room to room.
Can I install a mini-split on a landmarked or historic-district Brooklyn building?
Usually, but placement matters. In landmarked districts and many co-ops, the outdoor condenser typically needs to sit where it isn't visible from the street, and some buildings require board or LPC-aware approval. We plan the line routing and condenser location to respect those constraints while keeping the system serviceable.
My Brooklyn brownstone still has the original cast-iron boiler — should I repair or replace it?
Cast-iron boilers can run 30–50 years, so age alone isn't a reason to replace. If it's a single failed component, repair usually makes sense. If it's over 20 years old, needs repeated repairs, or has a cracked section, a high-efficiency condensing boiler can cut fuel bills significantly. We give an honest repair-vs-replace assessment rather than defaulting to replacement.
Do you handle HVAC for new-construction condos and gut renovations in Brooklyn?
Yes. For new construction and full gut jobs we design the mechanical system from scratch — load calculations, equipment selection, ductwork or mini-split layout, and code-compliant installation — rather than trying to force an off-the-shelf system into the space.
