Heat Pump Installation in Mercer Island, WA
One system that heats and cools, runs on electricity, and pairs perfectly with solar. The modern standard for Pacific Northwest comfort.
Heat pump siting on Mercer Island depends heavily on where a home sits relative to the lake — a shoreline Point home near 18 feet of elevation has different moisture and grading considerations than a house up near the Rotary Park ridge at almost 400 feet, and we plan the outdoor unit placement and line routing around that block-by-block terrain change.

Heat Pump Installation in Mercer Island: what's different here
Elevation on the island runs from about 18 feet at the lakefront to almost 400 feet near the ridge, so equipment placement, condensate drainage and access change from block to block. Older Mercer Island homes in East Seattle and the North End can take a heat pump, but the ductwork, panel and insulation have to be checked first. We often pair a ducted heat pump with duct sealing, or use ductless heads where the ducts are too small.
