Our Take on Beacon Plumbing, Heating, Electrical & Mechanical

Beacon earns its place with round-the-clock availability, no after-hours fee and more than 3,400 reviews. It is a plumbing-first company, though, so treat it as the emergency call and go to an HVAC specialist for a new system.

About Beacon Plumbing, Heating, Electrical & Mechanical

Beacon Plumbing, Heating, Electrical & Mechanical was founded in 1995 by Bill Cahill, who started with five trucks. Its Seattle location is on 7th Avenue South, near the International District, and it has 3,498 Google reviews at a 4.6 average as of September 23, 2026. Beacon also serves Bellevue, Everett, Tacoma and other parts of the region.

Plumbing is Beacon's main business, and it is worth being clear about that. Almost all of the recent Google reviews we read were for plumbing: water heaters, leaks, sinks and supply lines. The company's Google listing also covers HVAC contracting, heating, furnace repair, air conditioning repair and mechanical work, and its Seattle page says it handles HVAC service, but it gives few details about the heating equipment it installs. We placed it on this list because of its 24/7 availability and very large, well-rated review base, not because it is a heat pump specialist.

The availability is the real strength. Beacon says it answers 24 hours a day, seven days a week, including holidays, and does not add a fee for after-hours emergency calls. One reviewer said three other companies that advertised 24/7 service could not come until Tuesday after a Sunday morning water heater leak, while Beacon had a technician there within a couple of hours. Reviewers name Josh, Matt, Jon, Jeremy and Giovanni for clear explanations and clean, fast work.

Beacon backs parts and labor with a one-year guarantee and describes itself as licensed, bonded and insured. Its website does not print a Washington contractor license number, so ask for it and check it on the L&I lookup. It does not list financing or a maintenance membership on its Seattle page. We could not find usable job photos on its Google profile, and its logo could not be pulled for this profile.

Beacon suits Seattle homeowners who need someone at the door quickly for a furnace or water heater problem at night, on a weekend or on a holiday. For a planned heat pump or furnace replacement, a dedicated HVAC contractor higher on this list is the better first call. Ask whether a heating specialist, rather than a plumber, will be sent.

Beacon Plumbing, Heating, Electrical & Mechanical FAQs

  • Does Beacon charge extra for after-hours HVAC calls?

    No. Beacon says it answers 24 hours a day, seven days a week, including holidays, and does not add a fee for after-hours emergency calls.

  • Is Beacon Plumbing an HVAC company?

    Beacon is mainly a plumbing company, but its Seattle location lists heating, furnace repair, air conditioning repair and mechanical services. Ask for a heating technician when you call.

  • What guarantee does Beacon offer?

    Beacon advertises a one-year guarantee on parts and labor. Ask for the terms in writing, along with its Washington contractor license number.

  • Is Beacon Plumbing, Heating, Electrical & Mechanical licensed and insured?

    We have no credential records on file for this company yet. Ask for the certificate directly from the insurer before booking work.

  • What areas does Beacon Plumbing, Heating, Electrical & Mechanical serve?

    Seattle. Coverage is as the business describes it, cross-checked against where its recent documented work is. Confirm your address before scheduling, particularly at the edge of a service area.

  • Does Beacon Plumbing, Heating, Electrical & Mechanical offer emergency service?

    Yes, the company lists emergency availability. Response time depends on demand, and after a storm every company in the market is stretched.

  • What warranty do they offer?

    1-year guarantee on parts and labor.. There are usually two warranties on a job: the manufacturer covers materials, the contractor covers workmanship. Get both in writing and check whether the workmanship coverage transfers if you sell.

  • How was this profile built?

    Credentials come from issuing authorities, ratings from the company's Google Business Profile with the date we read them, and the editorial take from our own review of estimates, warranty documents and public feedback. Anything the business told us is labelled as reported.

  • Can a business pay to improve its profile?

    A business can subscribe to manage its own listing details, and it can buy a labelled sponsored placement. Neither changes a ranking position or the editorial assessment on this page.
