Storms come through often
Westmoreland County saw 546 severe weather events between 2015 and 2024, including 441 cases of damaging wind, 59 hail events and 14 tornadoes. That is a lot of chances for something outside to take a hit.

Step 1 of 3: Equipment
Power doesn't always hold
15% of Pennsylvania households went at least a full day without power in 2024. A boiler needs electricity to run its igniter and controls, even though it burns gas, so a long outage means no heat no matter how sound the unit is.
Half the homes in Westmoreland County went up in 1964 or earlier.
A boiler that old is closer to its last winter than its first.
Heat starts up in October, and a weak part fails right when it has to work
If your boiler is original to a house built in 1964 or earlier, ask the technician for more than a price on the part that failed. Ask how many years are left in it. A cracked heat exchanger or a cycling pattern that keeps getting worse is a sign the repair is just a bridge to a replacement, not a fix that holds. For a boiler installed more recently, that same repair is a different call, since there's no clock running out behind it. Get the honest answer on what's left before paying for the fix.
If a storm got to it, get it checked before the cold does
Power coming back on doesn't mean the boiler came through clean. If it sat through hail or wind, get a technician to look at the vent, the flue connection and the controls before trusting it to carry you through winter.

Watch for cold rooms and odd noises
A boiler losing its grip usually shows up as rooms that stay cold no matter how high the thermostat is set, or a kettling and banging sound coming from inside the unit. Water leaking at the base, a pilot or igniter that won't hold, and short cycling where it fires and shuts off again and again are all signs the boiler is struggling to do its job.
Some of these signs can't wait
A knocking sound, a burning smell, or soot around the unit means stop using it and get a technician out, not schedule one for next week. Most other signs, like weak heat or a noisy start, still mean the boiler is working harder than it should. Left alone, that strain tends to end in a bigger failure instead of fixing itself.
A boiler that keeps running with a fault doesn't stay at that same level of trouble. A cracked heat exchanger lets exhaust gases mix with the air the system should be keeping separate, and every hour it fires makes that crack worse, not better. A pump struggling against a clog or a bad bearing will keep drawing power and keep straining until it seizes. Low water pressure that gets ignored can let a boiler run dry in spots, and metal that overheats that way warps in ways a technician can't bend back. Soot building up on a burner or a heat exchanger insulates the metal from the water around it, so the boiler works harder to push out the same heat, and that extra strain lands on the same parts that were already struggling. The problem that's cheap to fix this week is rarely the one still waiting next week.
A diagnostic visit starts with questions. What does the boiler do, when does it do it, and what does it sound like right before. Then the technician checks water pressure on the gauge, looks for leaks around the pump and valves, and opens the panel to look at the burner and heat exchanger. Combustion gets tested with a meter, since a flame that looks fine to the eye can still be burning wrong. The flue and vent connections get checked for a clean path outside, because a blocked vent turns the boiler dangerous in a way a cold room never does. Controls and safety switches get tested last, since a part that passes every other check can still fail there and shut the whole system down.
