Landmarks Preservation Commission (LPC) HVAC Standards

As New York City’s first designated historic district, Brooklyn Heights enforces strict preservation rules governing all exterior mechanical equipment:

  • Street Facade Protection: Absolute prohibition of refrigerant line-hides or mechanical equipment on visible street-facing facades.
  • Rooftop Sightline Setbacks: Rooftop heat pump condensers must be mathematically positioned behind front parapets so they are invisible from the street curb.
  • Acoustic Decibel Thresholds: Dense lot lines require ultra-quiet variable-speed inverter compressors operating below 52 dB(A) with vibration damping mounts.
Townhouse Riser Routing: We utilize inactive masonry chimneys and internal utility chases to run line sets from cellar to top-floor suites with zero exterior impact.

Whisper-Quiet Steam Balancing & Cellar Vault Engineering

Historic Brooklyn Heights townhouses frequently suffer from noisy, overheating one-pipe and two-pipe steam heating systems. Our specialized technicians restore quiet balance:

  • Vapor-Cycle Pressure Calibration: Converting aggressive 5-7 PSI boiler settings down to gentle, whisper-quiet 0.5 to 1.5 PSI vapor pressures that eliminate violent radiator hammering.
  • Cellar Vault Equipment Mounting: Installing high-capacity condensers in private rear lightwells or sunken cellar vaults using vibration isolation pads.
  • Main Line Fast-Vent Balancing: Installing commercial Gorton main air vents to ensure steam reaches top-floor master bedrooms at the exact same moment as the parlor floor.
Brooklyn Heights Client Testimonial:

“Living in an LPC historic district, we were dreading the heating overhaul. Air Rescue handled the steam boiler balancing and vaporstat adjustment. For the first time in 15 years, our radiators don’t hiss or bang.”
