Job lines stand in Frame B. Frame B inspection-page lines: furnace repair $100-$600, minimum service fees $75-$200, labor $75-$150 per hour, after-hours emergency $140-$210 per hour. The frames price the same job differently -- an ignitor at $144-$479 in Frame A against $100-$250 in Frame B, a heat exchanger at $96-$1,437 in Frame A against $1,000-$3,000 in Frame B -- a frame difference, never averaged, never blended.
The neighbours named apart
Named apart, never a row here: furnace maintenance and tune-ups, a planned maintenance visit on its own page; heat pump repair, its own cluster; and mini-split repair, its own cluster -- this cluster prices furnace repair, the breakdown repair visit alone.
The local read
The local read: the frames above are national published frames; a written quote for one address, one problem line, and one part line is the only local figure.

Frequently asked questions
What does repair print at against replacement, as reported?
Repair prints at an average of $304 in Frame A, a $125 to $480 band in Frame B, and $100 to $600 on the Frame B inspection page. Replacement prints at $2,000 to $5,400 inside Frame B; Frame A prints no replacement line.
What does a heat exchanger print at on each ticket, as reported?
On the repair ticket, Frame A prints the heat exchanger part row at $96 to $1,437. Frame B prints heat exchanger replacement at $1,000 to $3,000 as a replacement-of-part row, apart from the $2,000 to $5,400 full-replacement ticket.
What does the repair ticket hold that replacement does not?
Part rows: ignitor at $144 to $479, flame sensor at $144 to $240, filter at $1 to $34 in Frame A; diagnostic at $90 to $100 in Frame B. The full-replacement ticket holds none of those rows.
Do the frames change on this guide?
No. Frame A averages $304 with a $123 to $505 range, Frame B prints repair at $125 to $480. The versus rows blend nothing, and frame differences stand named as frame differences.
Is furnace maintenance the same purchase as replacement here?
No. Furnace maintenance is a planned tune-up visit on its own page, named apart, and heat pump repair and mini-split repair stand in their own clusters. This guide prices the repair ticket against the replacement ticket apart.
