Furnace Blowing Cold Air? Here's What's Wrong — what South Salt Lake homeowners should know

Local note for South Salt Lake: at 4,266 ft elevation, HVAC equipment loses roughly 17% of nameplate capacity. Issues that would be minor at sea level can become symptoms here — we factor elevation into every diagnostic.
Most likely causes in South Salt Lake
Thermostat fan set to ON instead of AUTO
The blower runs continuously regardless of whether the burner is firing. Between heat cycles, you feel cool air at the vents. Switch fan to AUTO.
Most commonFurnace in lockout from failed ignition
Tried 2–3 times to ignite, gave up, locked out for 60 minutes. Blower may run; burner is off. See /problems/furnace-not-igniting.
CommonDirty flame sensor
Burner lights briefly then goes out within 5 seconds. Blower keeps running through the post-purge cycle then shuts off. Repeats next cycle.
CommonPilot light out (older standing-pilot furnaces only)
Pre-2000 furnaces with a constantly-burning pilot. If the pilot blows out (drafty install, dirty thermocouple), the gas valve closes.
