Nine months of heat a year
A furnace in Somerset County runs from September through May. That is most of the year asking the igniter, the blower motor and the heat exchanger to cycle on and off, day after day.

Step 1 of 3: Equipment
Long runtime means less margin
A part that is worn but still working can get through a mild winter unnoticed. Here, with storms hitting the county repeatedly over the past decade and the furnace carrying the house for nine months, a weak part gets found fast. A proper diagnosis catches what's actually failing instead of guessing.

Half the furnaces in Somerset County are heating a house built in 1964 or earlier.
A furnace that old, or close to it, may be nearing the end of its working life, and that changes whether a repair is worth paying for.
Oil runs $25.15 per million Btu, and this furnace runs September through May
A furnace that's struggling doesn't just run, it runs longer to make up for whatever's wrong. A clogged burner or a bad igniter means more cycling, and more cycling on oil adds up fast at these prices. If yours is short-cycling, or running longer than it used to just to hold the house at temperature, that's worth a service call now rather than waiting. Catching it early is usually a smaller repair than catching it once the system's been struggling for weeks.
Have it diagnosed before the next cold snap finds the weak part for you
A furnace carrying nine months of heat a year does not get much downtime to reveal a problem on its own terms. Get it looked at now, while it's one part acting up, not the whole system straining through a storm week.
Find a contractor
Ask what's left before you pay for what's broken
If a repair tech is already coming out for the diagnosis, ask them straight: how many years does this furnace have left. They can look at the heat exchanger and the overall condition and give you a real answer, not a guess. That answer is what decides whether this repair is worth paying for or whether the money is better put toward a replacement. A furnace near the end of its life can still be worth one more repair if the part is cheap and the rest of the system is sound. It is not worth it if the tech is telling you three more things are close behind it.
What you can check yourself
Make sure the thermostat is set to heat and the setting is above room temperature. Check the furnace switch, it looks like a light switch on or near the unit, and make sure nobody bumped it off. Look at the breaker for the furnace in the panel. Check the filter, if it's gray and packed with dust, swap it, a blocked filter can starve the system of airflow and shut it down on its own safety switch. If you have a standing pilot, see if it's lit, and follow the lighting instructions printed on the unit if it's out.
What to leave alone
Do not open the burner compartment or touch the heat exchanger. Do not try to relight an electronic ignition system, it should light on its own when it calls for heat, and if it isn't, that's a sign for a tech to chase down, not you. If you smell gas or oil fumes, don't flip switches or search for the source, get out and call it in. Repeated shutdowns after a reset usually mean a safety switch is doing its job and catching a real fault, not a fluke worth ignoring.
Most furnace failures start with one part that wears down and makes everything downstream work harder. A flame sensor coated with residue stops reading the flame and shuts the burner off, even though nothing else is wrong. An igniter weakens with age and either glows too dim to light the gas or cracks outright. The blower motor's bearings wear until the motor strains, overheats, and trips its own limit switch. On an oil furnace, the nozzle can clog or the oil filter can choke with sediment, and the burner starts surging or shutting down mid-cycle. None of these start as a full breakdown. They start as a longer cycle, a delayed start, a burner that kicks on rough, and they get worse the longer the part keeps limping along.
A diagnostic visit starts before any panel comes off. A tech will ask what the furnace was doing right before it quit, whether it was short-cycling, running rough, or just stopped, because that narrows things down fast. Then they'll check the easy stuff first: power to the unit, the thermostat call, the safety switches, before going near the burner or the heat exchanger. On a gas furnace they'll watch the ignition sequence, does the igniter glow and light the burner cleanly, does the flame sensor hold the flame once it's lit. On an oil furnace they're looking at the burner itself, the nozzle spray pattern, whether the flame is steady or surging. Once they find the failing part, a good tech checks what's around it too, since a strained blower motor or a dirty flame sensor is often a symptom of something else working harder than it should.
