Know the signs

Signs your boiler needs service.

Most mid-winter no-heat calls trace back to something a yearly visit would catch.

Cold radiators

Usually trapped air. If bleeding doesn’t fix it, the circulator or the balance of the system.

Losing pressure

A sealed system shouldn’t need water added. Look for a leak, the expansion tank or the relief valve.

Short cycling

Firing and shutting off again and again: an oversized boiler, a failing control, air or low flow.

Banging or whistling

Strange noises, leaks or rising fuel bills are worth a look before the next cold snap.

How it works

Inspect. Repair. Plan.

Book the inspection before the heating season.

  1. 01

    Inspect

    Combustion, safety controls, pressure and the circulator, checked.

  2. 02

    Repair

    Small fixes like a relief valve or expansion tank are made on the visit.

  3. 03

    Plan

    If the boiler is near the end, you get replacement options before it fails.

Questions

Boiler service, answered.

Answers from licensed plumbers. Still unsure? Call (509) 535-5946, 24 hours a day.

How much does a boiler inspection cost?
Gold Seal’s boiler inspection and minor maintenance special is $200. A minor diagnostic and inspection starts from $304, and a major one from $456.
How often should a boiler be serviced?
Once a year, before the heating season. A service visit checks combustion, cleans the burner, verifies the expansion tank and relief valve, inspects the circulator and low-water cutoff, and bleeds air from the system.
Why is my boiler losing pressure?
Water is leaving the system: a leak in the piping, a failing expansion tank or a relief valve letting go. A hydronic system is sealed, so needing to add water again and again is a symptom, not maintenance. Replacing an expansion tank during a visit starts from $379.
Should I replace my boiler with a furnace?
Usually not. Hydronic heat is quiet and even, and switching to forced air means adding ducts through a finished house. When a boiler fails, a modern high-efficiency boiler is normally the better path. We lay out both.
How long does a boiler last?
A boiler that’s looked after commonly lasts 15 to 30 years, longer than most forced-air furnaces. Yearly service decides where in that range yours lands.
