Levittown's gas homes — conversions on PECO mains and newer condensing units in expanded homes — fail at ignition, flame sensing, and condensate. Gas triage asks different questions than oil: error codes, ignition attempts, and what the condensate drain is doing in a freeze.

Gas boiler faults may involve ignition, controls or circulation. Note any fault code and do not bypass safety controls.
Gas lives in two places: conversions where oil tanks were pulled and a gas line was run, and expanded or rebuilt homes that went straight to a condensing unit. That split matters, because a converted atmospheric boiler and a modern condensing wall-hung unit have almost nothing in common diagnostically.
Conversions often keep the old distribution — cast-iron radiators or baseboard — paired with a new gas boiler, and those hybrids produce their own fault patterns: pressure behavior the old system never had, condensate the old system never made. The Levittown guide maps where gas and oil split across the sections.
The short list, by how often the phone rings.
What the boiler is telling you, translated.
Lockout after a few ignition clicks, no flame: an ignition-side fault — the control tried and failed to establish a flame. Note the error code and how many attempts it makes. Flame that lights then drops within seconds: flame sensing — the burner proved nothing, so the control cut the gas. Lockout on the coldest nights only: suspect the condensate drain; walk the drain line and look for an exterior run that could be frozen.
Pressure gauge climbing toward the relief setting or dropping toward zero: water-side, not ignition — check the boiler pressure guide and the expansion tank. If your unit is a condensing model with its own fault family, the national condensing boiler repair page goes deeper; gas-specific triage for everything here starts on the national gas boiler repair page.
Look, listen, and write it down — do not open the casing.
Call with the code, the attempt pattern, and whether condensate is involved — gas triage in Levittown is fastest when those three are known.
Straight answers before you call.
Cold snaps punish marginal ignition parts — a weak igniter or coated flame sensor that survived fall fails under sustained hard firing. On Levittown's converted gas units, extreme cold can also affect draft or freeze an exterior condensate drain on condensing models. A lockout that only happens in cold snaps is a part telling you it is done; replace it before the next one.
The classic flame-sensor failure: the burner lights, the control does not detect the flame, and it shuts the gas off as designed. On converted units it can also be a grounding or draft issue confusing the sensor. It is one of the most common gas service calls and usually a straightforward repair — but stop resetting it and get the sensor checked.
It changes what the tech looks for first — conversions reuse the old chimney, old piping, and sometimes old controls, so draft issues, an oversized flue, and legacy wiring are all in play. A converted unit is not the same machine as a boiler built for gas from day one. Mention the conversion when you call; it puts the tech on the right fault track.
Yes — leave the house and call the utility's emergency line from outside; in Levittown that is PECO. Do not reset the boiler, relight anything, or try to find the leak yourself. The repair line comes after the utility clears the property, to inspect the boiler and restart it safely.
If the conversion included a condensing boiler, that is the condensate drain — acidic water the unit extracts from the exhaust has to go somewhere. Exterior runs can freeze on the coldest nights and shut the boiler down. If yours ices over in January, the fix is rerouting the drain inside, not replacing the boiler.
