Manhattan Plumber, Heating & HVAC

Licensed Master Plumber Serving All of Manhattan

Karl's Plumbing Heating & Cooling has been the trusted name for plumbing, heating, and HVAC services in Manhattan since 1935. Now in our fourth generation of family ownership, our Licensed Master Plumbers — Brian Karl (NYC DOB License #921) and Chris Deifel (NYC DOB License #2060) — bring decades of hands-on experience to every Manhattan project. Whether you need an emergency plumber for a burst pipe in a pre-war co-op or a complete boiler replacement in a Midtown commercial building, we have the expertise and licensing to get the job done right.

Manhattan's building stock presents unique plumbing challenges that general contractors simply can't handle. Pre-war co-ops with original cast iron risers, high-rise buildings with complex water distribution systems, historic brownstones with steam heating — these all require a Licensed Master Plumber who understands NYC building codes and DOB permit requirements. Karl's handles all paperwork, permits, and DOB filings so you don't have to.

Manhattan Neighborhoods We Serve

Downtown Manhattan: Financial District, Tribeca, SoHo, NoHo, Chinatown, Little Italy, the Lower East Side, the East Village, the West Village, and Greenwich Village. Downtown Manhattan's mix of converted loft buildings, historic row houses, and modern high-rises means diverse plumbing systems — from century-old cast iron to modern copper and PEX.

Midtown Manhattan: Midtown East, Midtown West, Hell's Kitchen, Murray Hill, Kips Bay, Gramercy Park, Flatiron, Chelsea, and the Garment District. Midtown's dense commercial and residential mix keeps our team busy with everything from office building boiler service to apartment plumbing repairs.

Uptown Manhattan: Upper East Side, Upper West Side, Harlem, East Harlem, Washington Heights, Inwood, Morningside Heights, and Hamilton Heights. Uptown has some of Manhattan's oldest residential buildings, and many still rely on original steam heating systems and cast iron drain lines that benefit from experienced maintenance.
