Expert HVAC installation services for Brooklyn homes and businesses
HVAC installation in Brooklyn ensures year-round comfort — from ductless mini-split systems and central air conditioning to heating upgrades, ventilation improvements, and complete mechanical system replacements. Lion Construction Management coordinates licensed HVAC contractors for system design, equipment selection, ductwork, refrigerant lines, controls, and commissioning. Whether you're adding AC to a home that's never had it, replacing an aging boiler, or installing multi-zone ductless splits, we manage the entire process — including any required structural modifications, electrical upgrades, and permit inspections.
Brooklyn renovation permitting varies significantly by neighborhood and building type. Brownstone and townhouse renovations in landmarked districts like Brooklyn Heights, Park Slope, and Fort Greene require Landmarks Preservation Commission approval for any exterior work and sometimes interior structural changes. Attached row houses share party walls with neighbors, which introduces structural considerations and party-wall agreements for any work that touches shared walls. Brooklyn co-ops and condos have their own alteration agreement processes, though typically less onerous than Manhattan. Lion Construction Management has filed hundreds of Brooklyn DOB permits and LPC applications — we know the neighborhood-specific requirements before work begins.

Equipment is installed, ductwork or line sets are run, thermostats are wired, and the system is charged and commissioned.
System is tested across all modes, airflow is balanced, and you receive operation training and maintenance guidance.
Mechanical systems in Brooklyn buildings — especially brownstones and pre-war townhouses — often involve modernizing century-old infrastructure. Galvanized steel supply pipes, cast-iron waste stacks, knob-and-tube wiring, and oil-fired boilers are common. Lion Construction Management coordinates licensed contractors to assess existing conditions, design upgrades, file DOB permits, and execute the work. In brownstones, plumbing and electrical runs are typically exposed in the cellar and concealed on upper floors — our project managers plan access points and patch strategies to minimize wall damage. Expect an initial survey of existing conditions, a phased plan that keeps your home habitable during work, and inspections at each stage before walls are closed up.
It depends on your building type. Ductless mini-splits are ideal for Brooklyn brownstones, converted lofts, row houses, new-construction condos, and multi-family homes that lack existing ductwork — they provide efficient heating and cooling without major construction. Homes with existing ductwork benefit from central air upgrades. We assess your space and recommend the best solution.
A single-zone ductless mini-split in Brooklyn costs $4,000–$7,000 installed. Multi-zone systems (3–5 zones) range from $12,000–$25,000. Central air installation in a home with existing ductwork runs $8,000–$18,000. We provide detailed proposals after a load calculation and site assessment.
Yes. HVAC installations in Brooklyn require DOB permits, and many buildings have additional requirements for condenser placement, line set routing, and noise compliance. Many Brooklyn neighborhoods are in historic districts, which may require Landmarks Preservation Commission (LPC) review in addition to DOB permits. We handle all permitting and coordination.
Yes — that's exactly what ductless mini-split systems are designed for. They require only a small hole in the wall for the refrigerant line set, making them perfect for Brooklyn's brownstones, converted lofts, row houses, new-construction condos, and multi-family homes where adding traditional ductwork isn't feasible.
