What Renton homes need
Renton’s homes span its whole story, from the old coal-town streets to the Boeing and Kenworth years. Its housing reflects each era: older homes in the Highlands and near downtown, mid-century houses in Kennydale and on Talbot Hill, larger subdivisions on Benson Hill, and newer apartments and townhomes around The Landing. That spread shows up in our work:
- Postwar and mid-century homes: original ductwork, aging gas furnaces, small electrical panels and galvanized or older supply pipe.
- 1980s to 2000s subdivisions: first-generation high-efficiency furnaces and heat pumps now at replacement age.
- Townhomes and condos: compact water heaters, ductless systems and tight equipment spaces.
Renton weather
Renton has warm, dry summers and gray, wet, cool winters. Heating carries most of the year, but hot spells are real: during the late-June 2021 heat dome, Sea-Tac, just west of Renton, broke its all-time record. A heat pump that heats all winter and cools on those days is the most common upgrade we quote here.
