No heat at 6 am, fixed by 9
“Temperature dropped to 41°F overnight, furnace wouldn't ignite. Called at 6:18 am — tech was at our place by 7:40. Diagnosed a failed pressure switch (proved it with a manometer test), had the OEM Honeywell SmartValve part on the truck, swapped it. Also found a partly-clogged condensate trap was kicking the secondary safety. Fully tested under load before he left. House was 70°F by 9:30.”
