Boiler Services in San Francisco

San Francisco's high water pressure, tight Victorian layouts, and strict DBI codes make boiler work uniquely challenging. We are SF's boiler specialists — from high-efficiency combi installations to annual maintenance on vintage radiant systems.

Why Boilers in SF Require Specialists

High Pressure Is Always the First Problem

SF's water pressure frequently exceeds 130 PSI — nearly double the 80 PSI maximum safe limit. Every boiler we install or service in SF starts with a water pressure test. Installing new equipment without managing this pressure means premature failure in 3-5 years instead of 15-20.

  • Pressure test on every service call — not just installations
  • PRV and expansion tank installed or verified as part of every boiler job
  • City infrastructure work can spike pressure overnight without notice
  • High pressure destroys heat exchangers and safety components silently

Safe: 65 PSI · Maximum safe: 80 PSI · Typical SF: 130–140 PSI

Victorian & Edwardian Space Constraints

SF's housing stock presents unique spatial and structural challenges. Victorian flats have mechanical rooms sized for a 1960s water heater. Multi-unit Edwardian buildings have boiler rooms with 6-foot ceilings and no rear access. We specialize in making the right equipment fit the right space.

  • Wall-mounted combi-boilers are ideal for tight Victorian utility closets
  • Condensing boilers can vent through PVC when traditional flue runs aren't possible
  • We've installed in mechanical rooms as small as 20 square feet
  • All units seismically strapped per SF DBI code requirements

Making the right equipment fit the correct space

Full DBI Permit Management

Every boiler installation and major repair in SF requires a DBI permit. We manage the entire process from application to final inspection, ensuring your work is documented and fully code-compliant — protecting your home and its resale value.

  • We file the permit, coordinate the inspection, and attend the final walk-through
  • You receive a copy of the approved permit for your records
  • Non-permitted work creates complications at resale and prevents future insurance claims
  • We know SF's inspectors and what they look for — no re-inspections
