Avg pickup ~38 sec — Tap to callHeavy fog mornings drive Hughson furnaces hard, and a system that short-cycles wears out fast. Nine times out of ten the cause is a dirty flame sensor, a clogged filter, or oversized equipment that satisfies the thermostat too quickly.
Older Hughson homes with original 1970s ductwork lose 20–30% of their heat to the crawlspace before it ever reaches a register. Sealing and insulating those runs is the single highest-value fix we recommend out here.
Whole-house attic fans were a great idea in 1985, but most homeowners forget they're sucking conditioned air out the attic when the A/C is running. We routinely button these up or convert them to controlled ventilation.
