Annual maintenance is the most effective way to extend the life of your boiler — especially in Marin where hard water accelerates wear. We provide comprehensive service to keep your system running efficiently and prevent costly breakdowns.
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
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.
Essential for vintage radiant preservation
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.

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.
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.
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.
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.
Clean heat exchanger, flush system if needed, check all filters and strainers, and inspect all visible piping and components for signs of corrosion or wear.
Test all safety sensors and controls, inspect the pressure relief valve and expansion tank, check for gas leaks, verify proper venting, and confirm pump and circulator operation.
We provide a written service report documenting what we inspected, what we found, and any recommendations — so you have a record for warranty claims and resale.
