Takes about a minute. No obligation.
A furnace in Fayette County runs about eight months a year, with overnight lows averaging 22°F in December, January and February. That is a long, steady workload, not an extreme one. It wears parts out the normal way, over normal time.
Nothing about Uniontown puts a harder strain on a furnace than it sees anywhere else. When one acts up here, it is usually the same igniter, flame sensor or blower motor issue a tech sees all the time. Finding which one it is, and fixing that part, is the job.

Furnaces in Fayette County start running in October, right after September's mild stretch.
The first cold snap finds whatever part was already weak, so early October is when failures show up.
Natural gas ran $13.12 per million Btu in Pennsylvania in 2024. A furnace that short cycles or runs longer than it used to is costing more every month it sits unfixed. That does not mean anything is wrong with the gas line or the meter. It means a part is failing and making the furnace work harder to do the same job. The fix is the same one a tech would make anywhere else in the state.
Half the furnaces in Fayette County are running in houses built in 1959 or earlier. If yours is one of them, a repair might only buy a short stretch of time. Before paying for the part, ask the tech straight out how many years they'd expect to get out of this furnace.
Find a contractorBefore anyone comes out, there are a few things worth checking. Look at the thermostat first. Make sure it's set to heat, not just fan, and that the set temperature is actually above room temperature. Check the batteries if it uses them. Next, look at the furnace itself for a light. Most have a small window showing a flashing light, and that flash pattern points to a specific fault if you look it up against the panel inside the furnace door. Check the air filter. A filter packed with dust chokes airflow, and some furnaces will shut themselves down rather than run with no air moving across the heat exchanger. Check that the switch on or near the furnace, the one that looks like a light switch, hasn't been bumped off. Also check any switch near the furnace that looks like it belongs to a shop vac, because that's sometimes the furnace's own power switch. If the furnace uses a condensate line, look for a kink or a clog there too, since a blocked line will shut the whole system down on purpose. None of this tells you what part has failed. It just rules out the things that aren't actually broken.
A hot surface igniter is a thin strip that heats up to light the gas, and it gets more brittle every time it cycles. Eventually it cracks or stops glowing hot enough, and the furnace won't light at all. It's a wear part, not a sign of anything else wrong.
The flame sensor tells the control board the burner actually lit. A thin coat of oxidation on the rod can block that signal, so the furnace fires for a few seconds and shuts off, over and over. It looks like a serious fault but it's often just a rod that needs cleaning.

Repair makes sense when one part has failed and the heat exchanger is sound.
Replacement makes sense when the heat exchanger is cracked or the furnace keeps needing parts.
Age matters more than the symptom when you're deciding whether to fix a furnace or replace it. A control board or a blower motor can be swapped on almost any furnace and it runs like normal again. A cracked heat exchanger is a different conversation, because that's the part that keeps carbon monoxide out of the air you breathe, and once it's cracked the furnace needs to be replaced, not patched. The other thing worth asking is how many repairs this same furnace has needed. One failed igniter is normal wear. A furnace that's had the igniter, then the flame sensor, then the blower motor, all within a couple years, is telling you the rest of its parts are wearing out together, not separately. At that point a repair fixes what broke this week, not what's about to break next.
