Preserving Architectural Integrity & Precision Heating

Brownstones in Cobble Hill and Carroll Gardens require extraordinary care during HVAC modernization:

  • Narrow Cellar Access & Cast-Iron Replacements: Tight brownstone trapdoors and stairs require modular boiler delivery and near-boiler piping fabrication in place.
  • Steam & Hydronic Multi-Zone Balancing: Modernizing one-pipe steam and hot water loops with high-efficiency Taco circulator pumps, air separators, and expansion tanks.
  • Concealed Slim-Duct Mini-Splits: Running refrigerant line sets through closets and chimney chases to avoid altering historic plaster crown moldings and ceiling medallions.
  • Landmarks LPC Compliance: Non-visible rear yard or line-of-sight rooftop condenser setbacks that fully comply with LPC guidelines.
