Attic too hot in summer — San Francisco, California
An attic that reaches 140–160°F in summer can radiate heat into living spaces, overwork your AC, and shorten roof shingle life. Poor ventilation is the primary cause — soffit vents may be blocked by insulation, ridge vents may be missing, or the attic may lack sufficient exhaust capacity. An HVAC technician or roofer can evaluate ventilation, add powered or passive vents, and improve insulation to reduce heat transfer.

The cool, foggy maritime climate means central AC is rare and rarely needed, so HVAC work centers on heating efficiency, ventilation, and increasingly heat-pump retrofits driven by Title 24 energy rules. Older homes often have undersized or outdated heating systems requiring careful upgrades.
