Regular boiler maintenance is essential in San Francisco where high water pressure and aging pipes create constant wear. Our comprehensive service protects your system from SF's unique challenges and keeps your heating running reliably all season.
SF's water pressure — often 130+ PSI — stresses every component in your boiler system continuously. Without annual service, pressure relief valves can freeze in place and expansion tanks can waterlog, creating dangerous over-pressure conditions. We test and verify these components on every visit.
We verify water pressure on every maintenance call — most SF plumbers don't
SF's ongoing water main and infrastructure replacement projects send sediment into your plumbing regularly. This sediment can collect in your boiler's heat exchanger, reducing efficiency and causing damage. Annual flushing removes this buildup before it causes problems.

A well-maintained boiler in SF lasts 15-20 years. Without regular service, expect major repairs or full replacement within 8-10 years. Annual tune-ups catch small problems before they become expensive emergency calls.
Catch small problems before they become emergencies
We test water pressure, verify the PRV and expansion tank are working correctly, and test the T&P relief valve. In SF, this step is critical — high pressure accelerates failure of every safety component.
We inspect the heat exchanger for scale buildup and clean as needed. SF's water is moderately hard, and sediment from city infrastructure work adds additional debris to the system.
We test gas pressure, verify proper combustion with an analyzer, check for CO leaks, and inspect all gas connections and venting components for integrity.
We verify circulator pumps, zone valves, and all controls are functioning correctly. A failed zone valve is a common cause of uneven heating in SF Victorian homes with multiple zones.
Unlike most plumbers, we bring and use a pressure gauge on every service call. SF's high pressure is the silent killer of boiler components — and it can change overnight with no warning.
SF's Victorian and Edwardian homes have unique pipe layouts, old zone configurations, and sometimes original cast-iron radiators. We know how these systems work and how to service them correctly.
Every visit includes a written service report documenting what we inspected and found. This creates a maintenance record for warranty claims and adds value at resale.
