Part readings, priced apart by frame
| Failed part row | Frame B reading | Frame A reading |
|---|---|---|
| Thermostat row | $150-$300 total | inside the $166-$799 overall band |
| Ignition and flame-sensing row | $200-$500 total, gas units | inside the $150-$750 natural gas band |
| Control board and electrical row | $300-$700 total | inside the $200-$1,200 electric band |
| Pressure switch row | no build-up row by that name | inside the $166-$799 overall band |
| Heat exchanger row | $600-$1,200 total | inside the $166-$799 overall band |
| Blower and venting row | no build-up row by that name | inside the $166-$799 overall band |
| Compressor row, heat-pump units | $800-$1,500 total | no by-type row by that name |
Each reading is one frame counting of one failed part. Rows absent in one frame are printed as absent, never filled from the other.
Thermostat, ignition, and control board rows, priced apart
| Row | Frame | 2026 reading |
|---|---|---|
| Thermostat row, 0.5-1 labor hour | Frame B | $50-$200 part, $150-$300 total |
| Ignition system row, gas units, 1-2 labor hours | Frame B | $100-$300 part, $200-$500 total |
| Control board row, 1-2 labor hours | Frame B | $200-$500 part, $300-$700 total |
The Frame B rows are repair-visit rows -- one failed part on one visit -- never an installation hub row.
The heat exchanger and compressor rows, priced apart
| Row | Frame | 2026 reading |
|---|---|---|
| Heat exchanger row, 2-3 labor hours | Frame B | $300-$800 part, $600-$1,200 total |
| Heat exchanger read | second trade read | $1,200-$2,000 |
| Compressor row, heat-pump units, 2-4 labor hours | Frame B | $400-$1,000 part, $800-$1,500 total |
| Diagnostic visit row | Frame B | $125-$195 |
| Repairs typically row | Frame B | $160-$802, average around $479 |
| Labor row, per hour | Frame A | $80-$120 |
| Solar repair band row | Frame A | $50-$400 |
| Parts row | Frame A | $20-$600 |
The heat exchanger stands counted two ways here. The frames count the same job on different bases -- flat by-type bands in Frame A (repairs overall at $166-$799, an average about $477) against a part-plus-labor build-up in Frame B (a thermostat at $150-$300 in total, a compressor at $800-$1,500 in total, repairs typically at $160-$802 with an average around $479). The heat exchanger line is counted two ways across the trade reads -- $600-$1,200 in the Frame B build-up against $1,200-$2,000 in a second trade read reported in a repair-vs-replace trade article -- named as frame differences on every page, never averaged.
The neighbours named apart
Type readings price apart on the companion guide. Named apart, never a row here: the standing pool heater replace vs repair guide (its own field -- this cluster carries no repair-vs-replacement guide of its own), the pool heater installation hub (a new heater going in, its own field), the built pool pump repair cluster (the pump circuit, not the heater), and whole-pool renovation tickets, each in its own lane.

Frequently asked questions
What does pool heater repair cost by part, as reported?
Frame B prices the thermostat at $150 to $300, the ignition repair at $200 to $500, and the control board at $300 to $700, each in total. Frame A prices the visit inside its $166 to $799 overall band, with solar repairs at $50 to $400.
What do the heat exchanger rows print at, as reported?
Frame B prints the heat exchanger at $600 to $1,200 in total. A second trade read prints $1,200 to $2,000 -- counted two ways.
What does the compressor row print at, as reported?
Frame B prints the compressor on heat-pump units at $800 to $1,500 in total. Frame A prints no row by that name.
What do the pressure switch and blower rows print at, as reported?
Neither frame prints a build-up row by those names: each stands inside the Frame A band at $166 to $799, printed as absent.
Is a part row the same purchase as a new heater on the installation hub?
No. Each row prices one failed part in one repair visit. The installation hub, the standing decision guide, and the pool pump repair cluster sit in their own lanes.
