The scope readings, priced apart by frame
| Scope | Frame A reading | Frame B reading |
|---|---|---|
| First-time installation, new circuit run in the job | $369-$914 installed ticket | in installed rows |
| Replacement on existing wiring | in installed ticket rows | $300-$600 powered fan installed |
| Removal only, no new fan in the job | no standalone row | no standalone row |
Each reading is one frame counting of one scope in one job, never blended into a visit total. The first-time scope carries the wiring run inside the job counting; the replacement scope reads on wiring already in place; the removal-only scope stands with no standalone published row in any frame here, and that absence is printed rather than filled with an invented figure.
The first-time rows, priced apart
| First-time row | Frame | 2026 reading |
|---|---|---|
| Installation ticket, first-time scope | Frame A | $369-$914 |
| Average ticket, first-time scope | Frame A | $625 average |
| Solar unit row, first-time scope | Frame C | $108-$489 unit alone |
First-time rows count a job with no fan in place before it: the ticket frame carries the full installed band, and the retail frame carries the unit alone before any installation line exists. The new circuit run is read inside the first-time ticket, never broken out as a blended adder on this page.
The replacement and removal rows, priced apart
| Scope row, as published | Frame | 2026 reading |
|---|---|---|
| Powered attic fan, installed, replacement scope | Frame B | $300-$600 |
| Electric type row, replacement scope | Frame A | $100-$450 |
| Solar type row, replacement scope | Frame A | $300-$1,000 |
| Removal only | either frame | no standalone row |
Replacement rows count a fan swapped on wiring already in place. Removal-only stands apart from both: no frame here prints a removal-only ticket, so the row is recorded as an absence, never priced from another scope. The frames count the same single-fan job differently -- an installed ticket at $369-$914 in Frame A against a powered fan installed at $300-$600 in Frame B against a solar unit row at $108-$489 in Frame C, a unit row with no installation in it. That difference is named as a frame difference on every page here, never averaged.
The neighbours named apart
Type readings price apart on the companion guide. Named apart, never a row here: the attic ventilation system ticket, a system field whose ridge, soffit, gable, and baffle rows live on the ventilation guide alone; the whole-house fan, a different appliance moving whole-house air; and the attic insulation, attic ladder, and attic conversion tickets, each in its own lane.
