Seattle's marine climate keeps most summers mild, but the past few years have brought sharp heat waves pushing 90-plus degrees for several days straight. Many Seattle homes, especially older bungalows and mid-century ranches built before central air was standard, have attics and duct runs never designed for sustained cooling loads. That mismatch strains undersized systems and shortens equipment life faster than in drier climates.
Local knowledge
What's different about air conditioning services in Seattle
We run service calls in Seattle every week — the same patterns come up again and again.
Seattle City Light powers most homes here, and older electrical panels in pre-1960s bungalows often need a load check before adding a central AC condenser or heat pump.
Roughly two-thirds of Seattle's housing stock predates 1980, meaning original ductwork was sized for heating only and often restricts airflow once cooling equipment gets added.
Recent heat events, including the June 2021 heat dome that pushed Seattle past 100 degrees, showed how quickly aging AC units and ductless mini-splits can fail during multi-day highs they weren't built to handle continuously.

Straight answers
Air Conditioning Services in Seattle — FAQ
Do older Seattle homes need special work to add air conditioning?
Homes in neighborhoods like Ballard, Wallingford, and Capitol Hill, mostly built before 1980, often lack the return air space that central air systems need. That's why many homeowners in these areas choose ductless mini-splits instead of retrofitting old ductwork.
How fast can heat waves damage an AC unit in Seattle?
Seattle summers are short, but occasional heat domes, like the one in June 2021, can push a unit that normally runs a few hours a day into near-continuous operation for 72 hours or more, straining compressors that weren't designed for that load.
Does Seattle City Light or PSE affect my AC installation?
Seattle City Light supplies electricity to most Seattle properties while PSE typically handles natural gas in the city. Before installing a larger condenser or heat pump, we check your panel capacity, since older 100-amp services common in prewar homes sometimes need an upgrade first.
Do you service areas outside Seattle proper?
Yes, we cover Bellevue, Redmond, Kirkland, Sammamish, and Issaquah in addition to Seattle, with the same $149 starting service call and scheduling handled from our Seattle-based office.
