Fast, Local HVAC Service in Park Slope
Park Slope homes are unique — many are historic brownstones and co‑ops with steam or hydronic heat, limited ductwork, and varying electrical capacity. We specialize in non‑invasive solutions that fit older buildings, including high‑efficiency boilers, ductless mini‑splits for room‑by‑room comfort, and heat pumps that can both heat and cool with excellent energy efficiency. Whether you live near Prospect Park West, 5th Avenue, or the North/Center/South Slope, we’re nearby and ready to help.

Boiler Service & Installation
Steam and hot‑water boilers are common in Park Slope brownstones. We provide annual service, radiator balancing, circulator and expansion tank repair, and modern boiler upgrades.
