The repair visit split, stated head-on first

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.
Part bands: the pump, tank, valve, and control rows
| Part row, Frame A | Reading | Frame A note |
|---|---|---|
| Radiator valve | $180-$330 | valve row |
| Transformer | $180-$500 | control row |
| Zone valve | $200-$500 | valve row |
| Fan | $200-$500 | part row |
| Expansion tank | $200-$550 | tank row; the oil row prints $250-$530 apart |
| Flue | $300-$700 | part row |
| Circulating pump | $300-$1,000 | pump row |
| Gas valve | $300-$1,100 | valve row |
| Coil | $500-$1,000 | part row |
The pump rows stand apart: a circulating pump at $300-$1,000 in Frame A against a circulator pump at $350-$900 in Frame B, two readings of one named part. The tank, valve, and control rows stand apart the same way inside each frame, never merged into one band.
The same parts counted the other way: Frame B
| Part row, Frame B | Reading | Frame B note |
|---|---|---|
| Circulator pump | $350-$900 | pump row |
| Expansion tank | $200-$600 | tank row |
| Pressure relief valve | $150-$400 | valve row |
| Igniter or flame sensor | $150-$400 | control row |
| Thermostat | $150-$500 | control row |
| Zone valve | $200-$500 per zone | valve row |
| Air vent / automatic bleeder | $125-$350 | part row |
| Aquastat or control board | $300-$900 | control row |
| Heat exchanger | $1,200-$3,000+ | part row; no Frame A part-row counterpart |
Further rows as printed: Frame B prints a leak diagnosis line at $250-$750 and a system flush line at $200-$600, each apart.
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, differentiated
The standing furnace repair page prices the forced-air heating visit, a different job, and the standing heat pump repair page prices a heat pump visit; neither prices a part row here.
