No-heat calls: what we check first
Most no-heat calls resolve to a handful of causes: a tripped flame sensor or dirty igniter on a furnace, a failed thermocouple or low water pressure on a boiler, a clogged condensate trap on a high-efficiency unit backing up into the pressure switch, a seized circulator, or a control board that lost its mind after a power blip. We diagnose in a defined sequence and show you the failed component. On combustion equipment we also test for cracked heat exchangers and check draft and carbon monoxide, because a heating repair that ignores combustion safety isn't a repair.
