Problem readings, priced apart by frame
| Problem row, Frame A | Reading | Frame A note |
|---|---|---|
| Leak around boiler unit | $140-$750 | leaking row as printed |
| Strange noises from boiler | $1,000-$2,000 | noise row, carried on the heat exchanger line as printed |
| Unreliable heat | $200-$600 | no-heat row, carried on the power flush line as printed |
| Turns off unexpectedly | $250-$1,000 | problem row as printed |
| Won't turn on | $75-$1,800 | no-heat row as printed |
| No water pressure | around $200-$1,000 | pressure row as printed |
Each problem row here is priced only where a frame itemizes it, as printed. Frame B prints no by-problem table as printed: its problem-side lines stand as a leak diagnosis and minor repair line at $250-$750 and a system flush / water treatment line at $200-$600, named as service lines, never as problem rows. No no-heat row and no noise row is itemized in Frame B as printed; the absence stands as printed, never filled from Frame A.

Problem against problem, frame against frame
A leaking row reads at $140-$750 in Frame A against a noise row at $1,000-$2,000 carried on its heat exchanger line, while the no-heat rows read off the unreliable heat line at $200-$600 and the won't-turn-on line at $75-$1,800 -- readings of one visit, priced apart by problem and stated only where a frame itemizes the row. The frames price the same visit apart -- Frame A prints a circulating pump at $300-$1,000 while Frame B prints a circulator pump at $350-$900 for the same named part, an expansion tank at $200-$550 against $200-$600, and Frame B prints a heat exchanger line at $1,200-$3,000+ with no Frame A part-row counterpart -- a frame difference, never averaged, never blended.
The neighbours named apart
Named apart, never a row here: boiler installation and boiler replacement, a new unit as a different job; furnace repair, the forced-air heating visit; heat-pump repair, a heat pump visit; water-heater repair, a water heater visit; tankless installation and tankless descaling, their own lanes; HVAC replacement, a new system; the HVAC replace-vs-repair guide, its own read; and the appliance-repair umbrella hub, the generalist visit -- this cluster prices boiler repair, the boiler repair visit alone.

Is a heating visit priced on this guide?
No. Furnace repair is a standing forced-air heating page named apart and never rebuilt here, and boiler installation and replacement, heat-pump repair, water-heater repair, tankless installation and descaling, HVAC replacement, the HVAC replace-vs-repair guide, and the appliance-repair umbrella hub stand in their own lanes. This guide prices boiler repair by problem.
