New York City has more steam-heated buildings than any other city in the United States. Steam heat is efficient and reliable when the system is properly maintained — but it requires expertise that most modern plumbers don't have. One-pipe and two-pipe steam systems behave differently. Balancing steam distribution across a multifamily building requires knowledge of venting, pitch, trap sizing, and pressure settings that general plumbers simply don't develop.
Austin Plumbing has the steam heat experience that matters in NYC's pre-war building stock: boiler sizing for existing steam distribution systems, main vent selection and replacement, radiator steam trap replacement and balancing, pipe pitch corrections, and cycling and pressure adjustments that actually fix the problem. If you've been told your steam heat can't be fixed — a second opinion is worth the call.
