Takes about a minute. No obligation.
Your boiler here runs long and steady, heat on from October through May. Overnight lows average 22°F in the dead of winter, which is a normal workload for a boiler built to handle a real winter. Nothing about Bedford County pushes it harder than that. So when one starts short cycling, loses pressure, or won't hold a pilot, the cause is usually something plain. A failing igniter. A stuck valve. Sediment built up in the tank. A circulator pump wearing out after years of running. The job is finding which one it actually is, not guessing from a list.
A boiler that won't hold pressure or won't light right doesn't fix itself by running longer.
Keep firing it in that state and the next failure is usually the heat exchanger or the circulator pump, not the part that started it.
Half the homes in Bedford County were built in 1971 or earlier. If your boiler came with a house that old, it's worth finding out how many years the unit itself has, since a past remodel or replacement could put it anywhere in its life. An old boiler can still heat the house fine while losing ground on the parts that keep it safe, like the heat exchanger or the circulator pump. A repair is worth doing when the unit has years left in it. It's a different conversation when the same breakdown keeps coming back. Ask whoever comes out to look at it how much life is left before you spend real money on a repair.
Before any repair gets priced, ask how many years the boiler has left. That answer decides whether this is worth fixing or worth replacing.

A boiler that's starting to fail usually makes itself heard first. Banging or kettling in the heat exchanger means sediment has built up and is trapping steam pockets. A low hum or whine from the circulator pump means its bearings are wearing out. Neither of these fixes itself, and both get louder and worse the longer they run.
The noise tells you where to look, not how bad it is. Kettling can mean a simple flush or it can mean the heat exchanger is already scaling up for good. A failing circulator pump might just need replacing, or it might have been straining against a clogged line for months. Whoever comes out needs to see it running to tell the difference.
Most boiler failures come down to a handful of parts, and they fail for ordinary reasons. The igniter or pilot assembly wears out from years of heating and cooling every time it fires. The circulator pump runs for months without a break, so its bearings or its motor are usually the first mechanical part to go. Low water pressure often traces back to a slow leak somewhere in the system, or a pressure relief valve that's no longer holding. Sediment settles in the bottom of the tank over time and starts to insulate the water from the heat, which is what causes kettling. A thermostat or control board can also fail outright and stop the boiler from firing at all, even though every mechanical part is fine. None of these are rare or strange. They're just what gives out first on a machine that runs for months at a stretch.
A diagnostic visit starts with questions, not tools. When did it start, what does it sound like, has the pressure gauge moved. Then the tech watches it run through a full cycle, because a boiler can look fine sitting cold and show the problem the moment it fires. They'll check water pressure at the gauge, look for scale or leaks at the fittings, and listen at the heat exchanger and the circulator pump for the noises that give away wear. A combustion check on a gas or oil unit tells them whether it's burning clean. Most of this gets answered without opening anything up. Only once they know which part is failing does it make sense to talk about what fixing it involves.
