What Sherman Oaks's climate does to a system over time
The central San Fernando Valley holds heat late, with afternoons that stay hot well past sunset and push equipment into long summer run times. Valley air also traps haze and particulates against the hills, so filtration and a properly sized return are worth including with any change out. That's the exact reason every heating maintenance call opens with the same triage: heat load, dust buildup, and total run time, all checked against what Sherman Oaks and the central San Fernando Valley throws at equipment day to day.
