Boilers are less common than furnaces, but the homes that have them depend on them heavily
Older Peninsula homes with radiant heat rely on boilers
While most newer homes on the Peninsula use forced-air furnaces, many older homes in San Mateo, Burlingame, Hillsborough, and San Francisco still have hydronic (hot water) or steam boiler systems. These systems provide comfortable, even heat and can last for decades, but they do need periodic maintenance and occasional repair. Finding a plumber who actually works on boilers can be a challenge, which is why many Peninsula homeowners turn to us.
We diagnose and repair boiler issues that other companies pass on
We diagnose and repair common boiler and hydronic heating problems to keep your system running safely and efficiently. From heat loss and pressure issues to leaking components, we handle the key parts that affect performance.
Regular maintenance extends boiler life and prevents mid-winter breakdowns
Boilers are built to last, but they still need annual attention. A maintenance visit catches small issues before they leave you without heat on the coldest night of the year.
What to expect before, during, and after a boiler service
Before
Our technician inspects the boiler, checks pressure and temperature readings, and identifies the issue. We explain the problem and provide upfront pricing.
During
We complete the repair, whether it involves replacing a circulator pump, fixing a zone valve, addressing a pressure issue, or resolving an air lock. For maintenance visits, we work through the full checklist.
After
We test the entire system, confirm heat is reaching all zones, and verify pressure and temperature are within the correct range. We share recommendations for ongoing care.
6 Signs Your Boiler Needs Professional Service
No Heat or Uneven Heating
If your radiators or baseboards are cold or some rooms are not heating properly, the boiler, circulator pump, or zone valves may need attention.
Unusual Noises
Banging, clanking, gurgling, or whistling sounds from the boiler or radiators often indicate trapped air, low water levels, or sediment buildup.
Leaking Water
Any moisture around the boiler, pipes, or radiators should be addressed promptly to prevent water damage and system pressure loss.
Pressure Gauge Reading Too High or Too Low
Boiler pressure should stay within a specific range. Readings outside that range can indicate an expansion tank problem, a fill valve issue, or a leak.
Radiators That Need Constant Bleeding
If you are frequently bleeding air from your radiators to restore heat, there may be an underlying system issue that needs professional diagnosis.
It Has Been Over a Year Since Your Last Service
Annual boiler maintenance is the best way to prevent mid-winter breakdowns and extend the life of your system.
