No heat during an Ohio cold snap is not a next-week problem. Neither is a burning smell from the vents, water spreading from the air handler, a breaker that trips every time the system starts, or a furnace that locks out repeatedly after three ignition attempts. Demand spikes hard on the first sustained freeze, when furnaces that sat idle through a humid summer fail on first firing, so waiting usually means waiting longer.
Before anyone arrives it is worth checking four things that resolve a surprising share of after-hours calls: thermostat batteries and mode, the furnace door safety switch seated properly, the condensate float switch, and whether the breaker or service switch has tripped. If there is a smell of gas or burning, shut the system off and ventilate. Pro HVAC connects households in Vaughnsville, OH with professionals covering nights and weekends. Call (321) 463-9811.
