HVAC and electrical on Mercer Island, WA.

Black Lotus serves all of Mercer Island from the North End and East Seattle to Mercerdale, the South End, Faben, and Calkins Point. Mercer Island's housing mix is dominated by mid-century homes built between 1955 and 1985, which means most installs include a panel upgrade.

The three of us, Chase Tasca, Parker Reed, and Charlie Lightsey, were all born and raised in Seattle. Each of us has over a decade in the HVAC trade. Combined, we've seen what Mercer island's housing stock actually does in a wet October and a cold January, and we install systems that work for it.

What Mercer Island homes specifically need

Mercer Island housing breaks roughly into three eras.

Each one calls for a different approach. The 1965 ranch isn't the same as the 2015 custom rebuild, and we don't pretend it is.

  1. 01

    1955-1975 mid-century originals.

    North End, East Seattle, parts of Mercerdale. Original 100A panels, often with the original gas furnace from a 1990s replacement. Heat pump install almost always includes panel upgrade and sometimes ductwork modifications. Full project $22,000 to $30,000 net.

  2. 02

    1975-2000 expansion era.

    South End, Lakeridge, parts of Faben. Typically 200A panels, more modern ductwork, gas furnaces from 2000-2010 now aging out. Most installs are 2-day retrofits, $16,000 to $20,000 net.

  3. 03

    Modern teardown-and-rebuilds.

    Scattered across the island, especially North End and waterfront. Custom modern homes with 400A service, multi-zone ductwork, and existing high-efficiency systems. Work here is maintenance, IAQ upgrades, EV charging arrays.

The Mercer Island math

Why Mercer Island heat pump installs pencil out.

Mercer Island's mid-century housing stock is right in the furnace-replacement window — most original-build homes are on their second furnace and facing the third. Heat pumps replace both the aging furnace and the increasingly-needed AC in one project.

The math:

  • PSE rebate $1,200 instant — Mercer Island is fully PSE
  • Federal IRA tax credit Up to $2,000
  • Operating cost savings $500 to $700/yr on typical Mercer Island home
  • Marine-grade equipment Specified on every install for salt-air longevity

For a 2,600 sq ft mid-century replacing a 2005 furnace, the 10-year net cost picture favors a heat pump by about $6,000 to $9,000 after rebates, credit, and operating savings — even with the panel upgrade most original homes need.

Salt air from the lake is a factor for outdoor unit longevity. We spec marine-grade fin coatings on all Mercer Island installs.
