Pilot Light and Ignition Repair in San Francisco, CA

Older boilers run a standing pilot with a thermocouple, which makes the small voltage the gas valve needs to stay open. A pilot that lights and then goes out when you let go of the knob is usually a weak thermocouple.

Newer boilers use a hot surface igniter or spark ignition, followed by a flame sensor that proves the burner lit. A sensor coated in oxide reads too low and the control shuts the gas off after a few seconds. You see the burner light, then die, then try again until the boiler locks out.

Reliable Boiler Service connects San Francisco, CA homeowners with technicians who test these parts with a meter rather than swapping them at random: thermocouple millivolts, flame signal microamps, igniter resistance, gas pressure at the valve.

Smell gas? Leave the house and call your gas utility from outside first.

Pilot Light And Ignition Repair FAQs

Frequently asked questions about Pilot Light and Ignition Repair

Questions we hear most often about Pilot Light and Ignition Repair in San Francisco, CA.

Talk to a real person
Do condensing boilers work with old cast iron radiators?
They can, but they only condense when return water comes back cool. Outdoor reset control and properly sized radiators make the difference.
How often should a boiler be serviced?
Once a year, ideally before the heating season. Steam boilers with a float type low-water cutoff also need regular blowdown through the winter.
What does a lockout code on my boiler mean?
The boiler tried to light several times and failed, so it shut itself off for safety. Note the code before resetting, since it narrows the cause down to ignition, flame sensing, venting or water pressure.
Are there rebates for high-efficiency boilers?
Many gas utilities and state energy programs offer rebates on qualifying condensing boilers. Terms change often, so check your utility's current program before you buy.
How do I know if my boiler is the right size?
A room-by-room heat loss calculation is the only real answer. Boilers that short cycle on mild days are often oversized for the house.
