H&L Heating Supply

Brooklyn winters demand reliable heat. H&L Heating Supply keeps the borough’s boilers and radiators running from a storefront on Coney Island Avenue—1100 to be exact, just past the intersection with Avenue J. The shop specializes in parts and equipment for residential and small commercial systems, stocking everything from circulator pumps to zone valves and thermostatic controls.

Homeowners and contractors alike stop by when baseboard units sputter or furnaces refuse to ignite. The selection covers both modern high-efficiency models and older cast-iron components that still power many Brooklyn brownstones. No appointment needed; walk-ins can usually find what they need same-day, especially for common repairs like pressure-reducing valves or expansion tanks.

Midwood’s mix of pre-war walk-ups and newer condos means the neighborhood’s heating needs vary widely. A quick call to (718) 859-2424 can confirm whether a particular part is on the shelf before making the trip. Staff can also help troubleshoot compatibility for systems that have been patched together over decades.

Directions to the storefront are straightforward via the map here. If the radiator’s hissing louder than the Q train, this is where to start.
