Every way a Vandalia home stays warm.
Why does the furnace blow cool air when it first starts?
Because the burners light before the blower does, on purpose. The furnace gives the heat exchanger thirty seconds or so to warm up before it moves air across it, so the first air out of the vents is whatever was sitting in the ducts. If the cool air lasts longer than a minute or two, or the blower runs without the burners ever lighting, that is different: it usually means the furnace tried to fire and a safety stopped it, and it will keep retrying until it locks out.
Why does my furnace turn on and off every few minutes?
Short cycling. The furnace reaches its limit, shuts down, cools, and starts again, which burns more gas than running a full cycle would and wears the ignition components out early. The usual causes are a clogged filter starving the return, a flame sensor that needs cleaning, an oversized furnace that heats the thermostat faster than it heats the house, or a flue problem tripping the safety. The first is free to rule out yourself. If a new filter does not settle it within a day, the rest want a technician, because two of them are safety devices doing their job.
The heat is out and it is the middle of the night. What now?
Check three things before you call, because one of them fixes it more often than people expect. The furnace switch, which looks like a light switch on or near the unit and gets knocked off. The breaker. And the filter, if it has been in longer than you can remember. If none of those does it, call. The line is answered at any hour, and a house losing heat in an Ohio January is not a call worth putting off until morning, both for the house and for the pipes in it.
One room never gets warm. Is the furnace the problem?
Usually not. A furnace that satisfies the thermostat is doing what it was asked, and the room that stays cold is almost always a duct problem: a run that is too long or too small, a damper closed years ago and forgotten, a crushed flex duct in a joist bay, or a return that cannot pull enough air back for the supply to push. Adding return capacity fixes more of these houses than replacing the furnace does, and it costs a fraction of what a new system does. Ask for the airflow to be measured before anyone quotes you equipment.
