What South San Francisco housing means for HVAC service
Fog and wind are common much of the year. Most homes date from the 1940s to the 1960s.
Many homes have no air conditioning because summers are cool. Many mid-century homes have ducts in a crawl space or attic that were never sealed, and leaks there waste a lot of heated or cooled air. SFO is just south of the city.
Inland heat waves push older AC units past their limits, and wildfire smoke days make better filtration a common request. Genentech was founded here, and the city calls itself the birthplace of biotechnology.

Common questions
My thermostat is blank. Is the system broken?
Not always. Dead batteries, a tripped breaker or a blown fuse at the unit can blank the screen. Check those first.
What does a strange smell from my vents mean?
A dusty smell at the first heat of the season is common. A burning electrical smell or a rotten egg smell is not. Shut the system off and call, and leave if you smell gas.
Do I need my ducts cleaned?
Not on a fixed schedule. It can help after renovation dust, a pest problem or visible mold, but regular filter changes do most of the work.
