When the heat goes out in Glenview, IL, the clock starts running, and the diagnosis depends entirely on what kind of system is doing the failing. On a gas furnace, the single most frequent culprit is a flame sensor coated in oxide: the burners light, the sensor cannot prove the flame, and the board shuts the gas down after the third attempt and locks out. Close behind come cracked hot surface igniters, stuck pressure switches, clogged condensate traps on high-efficiency models, and blower motors that have quietly worn out. Heat pumps fail differently: a weak defrost cycle leaves the outdoor coil armored in ice, a failed reversing valve strands the system in cooling, and a dead outdoor unit leaves the electric backup strips carrying the whole house at several times the operating cost.
