Frequently asked questions
Why is my boiler not heating in Seattle?
The most common reasons a boiler stops heating in Seattle include a failed pilot light or ignition, a faulty thermostat, low water pressure, a stuck zone valve, a failed circulator pump, or a heat exchanger problem. Beacon Plumbing's licensed HVAC technicians diagnose boiler issues same-day and carry parts for the most common repairs, with most calls resolved in a single visit.
How long does a boiler last in Seattle?
A well-maintained gas boiler in a Seattle home or commercial building typically lasts 15-30 years. Annual maintenance, including a pressure check, heat exchanger inspection, and system flush, significantly extends the lifespan of the unit. Beacon Plumbing offers boiler maintenance service and replacement for all major brands serving Seattle residential and commercial customers.
What is the difference between a boiler and a furnace?
A furnace heats air and distributes it through ductwork, while a boiler heats water and distributes the heat through radiators, baseboard heaters, or radiant floor systems. Boilers are common in Seattle's older residential neighborhoods and commercial buildings and are generally known for even, comfortable heat distribution. Beacon Plumbing services and installs both systems across Seattle.
What Seattle customers are saying
Thousands of verified reviews from homeowners and businesses across the Puget Sound.
"Our boiler stopped producing heat on a Friday afternoon in February. Beacon arrived Saturday morning, diagnosed a failed circulator pump, and had the part with them. By noon we had heat back and the tech checked all the zone valves and bled the radiators while he was there. No trip charge and a fair price for a weekend call."
Ellen D. | First Hill, Seattle | No heat, failed circulator pump
"We have a 1970s boiler in our older Madrona home and Beacon has serviced it for three years running. They do a full inspection, flush the system, check the pressure relief valve, and always document what they find. Because of their preventive maintenance we caught a failing heat exchanger before it became an emergency."
Frank R. | Madrona, Seattle | Annual boiler service and flush
"I manage a 24-unit apartment building with a central boiler system. Beacon has handled two emergency repairs and our annual maintenance for the past two winters. They understand the urgency of getting heat restored to tenants and they are always upfront about what the repair will cost before they start. Dependable and professional."

A message from the owner
Built on hard work and a commitment to this community
Bill Cahill started Beacon Plumbing in 1995 with five trucks and a simple philosophy: hire great people, work hard, and treat every customer the way you would want to be treated. Thirty years later, that philosophy has not changed. What started as a small Seattle operation has grown into a team of 100 licensed, bonded, and insured technicians working around the clock to serve homeowners and businesses across the Puget Sound.
Bill believes deeply in giving back to the community that has supported Beacon's growth. Over the years, Beacon has sponsored the Miss Beacon Plumbing hydroplane at Seattle Seafair, supported Crime Stoppers of Puget Sound in the fight against human trafficking, donated musical instruments and a music teacher to St. George School, and partnered with Northwest Harvest, Ronald McDonald House, and Mamma's Hands. The Seahawks and Mariners logos on Beacon trucks are not just sponsorships - they are a reflection of Bill's pride in Seattle and the people who call it home.
When you call Beacon Plumbing, you are not calling a national franchise. You are calling a company that was built here, employs your neighbors, and is invested in this region for the long haul.
