The service
What boiler, radiator & hydronic heat service is, what a visit covers and where the line is.
The short answer
Hydronic heat warms a home by sending hot water, or steam, from a boiler through pipes to radiators, baseboard convectors or tubing in the floor. Boiler, Radiator & Hydronic Heat Service in San Bruno is booked through pros who cover its 1 ZIP codes, in neighborhoods such as Belle Air, Crestmoor, and Rollingwood. In San Bruno, the dry season from late spring to fall is the easiest time for outside work, and the fall calendar fills before the first big rain. Boilers burn fuel under pressure, so the work is licensed-trade work done by pros who hold the license.
If boiler, radiator & hydronic heat service is an emergency

- You smell gas, oil or exhaust near the boiler, or the carbon monoxide alarm sounds
- Water is leaking from the boiler, a pipe or a relief valve
- The pressure gauge is above the red line, or steam escapes
- There is soot, scorch marks or a flame rolling out of the boiler
- The house has no heat and temperatures are below freezing

License and permits for boiler, radiator & hydronic heat service
Boilers burn gas or oil, run under pressure and vent exhaust gases, so repairs, part replacement and combustion adjustment are licensed-trade work done by pros who hold the license. Bleeding a radiator or checking the pressure gauge are simple tasks you can do yourself.
Replacing a boiler, changing a gas or oil line, or altering the flue commonly requires a permit and an inspection. Small repairs of like-for-like parts often do not, and your pro tells you which applies.
Check the license on the pro profile before you book. After a replacement or gas work, ask to see the permit and the final inspection record, and keep the combustion test results with the boiler paperwork.

Before you book boiler, radiator & hydronic heat service
Quick things that save a trip. Tick them off as you go; none of it is required to book.
Photograph the boiler and its gauge
Take pictures of the boiler, the data label, the pressure and temperature gauge and any display or error code. They tell the pro the type, age and fuel before the visit.
Write down which radiators or zones are cold
List which rooms heat and which do not, and whether the cold ones are upstairs or at the end of a loop. The pattern helps the pro tell air from a failed valve or a blocked pipe.
Note the pressure reading
Read the pressure gauge when the system is cold and again when it is hot. A reading that rises too high or falls to zero overnight is a valuable clue.
Test your carbon monoxide alarm
Boilers produce carbon monoxide when they burn badly. Make sure there is a working alarm near the boiler room and near bedrooms before any service work begins.
Clear the boiler room
Move boxes and stored items away from the boiler and keep paints and chemicals out of the room. Pros need space to work and the burner needs air.
Keep the service records
Gather past invoices, the manual and any combustion test results. A history of repairs helps a pro decide between fixing and replacing.
