How long does a boiler last?

Most residential boilers last 15 to 30 years, depending on the boiler type, water quality, and how consistently the system is maintained. Cast iron boilers often outlast newer high-efficiency models, which have more complex components. Annual maintenance helps a boiler reach the upper end of its expected life.

Why is my boiler losing pressure?

A boiler usually loses pressure because of a water leak in the system, a faulty pressure relief valve, or a failing expansion tank. Bleeding radiators can also lower pressure temporarily. If you must repressurize the boiler often, schedule a repair so a technician can locate the source before the boiler or nearby surfaces are damaged.

What are the signs my boiler needs repair?

Signs a boiler needs repair include no heat or uneven heat, banging or gurgling noises, water leaks around the unit, frequent pressure drops, and a pilot light that keeps going out. A yellow or flickering flame on a gas boiler can point to a combustion problem. Prompt repair helps prevent water damage and protects the boiler's heat exchanger.

Should I replace my boiler with a different heating system?

Replacing a boiler with the same type of system is often the simplest choice because the piping and radiators are already in place. Switching to a furnace or heat pump may make sense if you also want central air conditioning, since those systems share ductwork. During a free estimate, we can compare installation needs and operating costs for each option.

What Our Boiler Technicians Do

Boiler service starts with an inspection of the burner, ignition system, pressure relief valve, expansion tank, circulator pump, and controls. The technician checks system pressure and water temperature, looks for leaks at fittings and the heat exchanger, and confirms the flue is venting properly. For repairs, you receive a by-the-job price before any parts are replaced. Common fixes include replacing circulator pumps, igniters, thermocouples, pressure valves, and zone valves, and bleeding trapped air from radiators or baseboard heaters. When a boiler is too old or damaged to repair economically, we evaluate your heating load and existing piping to recommend a replacement. Every visit to your Alamo Heights home ends with a full test cycle and a review of the work.
