Why Boiler Maintenance is Critical in Marin
Fighting Hard Water Buildup
Marin’s water has a high mineral content. These minerals create scale buildup inside your boiler’s heat exchanger, forcing it to work harder, reducing efficiency, and eventually leading to cracking — a condition called kettling. Our annual maintenance includes cleaning and inspecting the heat exchanger.
Average boiler life drops from 20 years to 8 years without annual service in Marin
Protecting Eichler Systems
The old steel and copper pipes in Eichler homes are prone to corrosion and sediment buildup. Regular system flushing and maintenance are essential to preserve these vintage radiant systems and protect the modern, sensitive boilers connected to them.

Extend Equipment Life
A well-maintained boiler in Marin should last 15-20 years. Without annual service, expect major repairs or replacement within 8-10 years. The math is simple: a $300 annual tune-up prevents a $10,000 premature replacement.

Our Marin Boiler Maintenance Checklist
Heat Exchanger Inspection & Cleaning
We inspect and clean the heat exchanger for scale buildup caused by Marin’s hard water. This is the most critical step to prevent overheating and failure.
System Flush
We flush the heating loop if necessary to clear sediment and debris — especially important for Eichler homes with older steel piping still connected to the system.
Safety Controls & Gas Test
We test all safety sensors, pressure relief valves, and gas connections. For gas boilers, we check combustion efficiency and test for any CO or gas leaks.
Pump, Valve & Expansion Tank Check
We verify all pumps, zone valves, and expansion tanks are operating correctly. A failed expansion tank is a common cause of pressure relief valve failure.
What’s Included in Our Tune-Up
Marin Boiler Maintenance FAQs
How often should I have my boiler serviced in Marin?
Once a year, ideally in early fall before heating season. Marin’s hard water means annual service isn’t optional — it’s how you keep the boiler running and the warranty valid.
What does a boiler tune-up cost?
A standard annual service visit typically runs $200-400 depending on the system complexity and what’s needed. For Eichler homes requiring a full system flush, the cost is higher. Contact us for a specific quote.
Can you service any brand of boiler?
Yes. We service all major brands including Navien, Lochinvar, NTI, Triangle Tube, Weil-McLain, and the original systems found in older Marin homes.
My boiler is running fine — do I still need service?
Yes. Hard water scale builds up silently until the heat exchanger fails — often without warning. By the time you notice a problem, you may already need a replacement. Annual cleaning prevents this.
