The problem readings, priced apart by frame
| Problem reading | Frame B reading | Frame C reading |
|---|---|---|
| Compressor | $800-$2,000+ problem band | $1,500-$2,800 part band |
| Leak | $300-$800 leak repair | $300-$1,000 leak row |
| Drain line | $75-$200 drain row | in part rows |
Each reading is one frame's counting of one problem inside one ductless repair visit, and per-problem rows are never blended into an installation row.
The problem rows, priced apart
| Problem row | Frame B reading | Frame C reading |
|---|---|---|
| Capacitor | $150-$350 capacitor row | $150-$400 capacitor row |
| Sensor and thermistor | $150-$400 sensor row | $100-$400 sensor row |
| Control board | $400-$900 board row | $300-$800 board row |
| Fan motor | $250-$650 motor row | $300-$700 motor row |
| Refrigerant recharge | $200-$500 recharge row | in part rows |
Frame B prints its problem rows; Frame C prints its part rows beside it, and a row with no line in one frame stands as in that frame, never filled from the other.
The visit lines, priced apart
| Visit line, as published | Frame | 2026 reading |
|---|---|---|
| Ductless mini-split | Frame A | $350-$1,200 |
| Diagnostic | Frame B | $75-$150 |
| Coil cleaning | Frame B | $100-$250 |
| Cleaning | Frame C | $100-$650 |
| Compressor | Frame C | $1,500-$2,800 |
The visit lines count a problem reading inside the repair visit alone: a new system going in is the installation hub's own field, named apart. The frames count the same compressor differently -- Frame B reads the compressor at $800-$2,000+ as a problem band, while Frame C reads the compressor at $1,500-$2,800 as a part band, and the drain line stands at $75-$200 in Frame B with no Frame A line of its own. Those differences are named as frame differences on every page here, never averaged.
The totals behind the rows, and the neighbours named apart
Behind the rows: Frame B typical at $150-$650 for a mini-split and $200-$1,200 for a multi-split, Frame A ductless at $350-$1,200 standing apart. The repair ticket against the replacement ticket prices apart on the companion guide. Named apart, never a row here: the ductless mini-split installation hub, its own field as an installation field pricing a new system going in; central-air systems, a separate class on their own guides; window and portable units, separate classes; and whole-system replacement, a new system purchase read on the repair-vs-replacement guide under each frame separately and by system form.

Frequently asked questions
What does mini-split repair cost by problem, as reported?
Frame B prints drain line at $75 to $200, capacitor at $150 to $350, control board at $400 to $900, and compressor at $800 to $2,000+. Frame C prints leak at $300 to $1,000 and compressor at $1,500 to $2,800. Frame A prints ductless at $350 to $1,200. A frame difference, never averaged.
What do the board rows print at, as reported?
Frame B prints the control board at $400 to $900 as its own problem row. Frame C prints its board at $300 to $800 as a part row, the two board readings standing apart in their own frames.
What does the refrigerant line print at, as reported?
Frame B prints leak repair at $300 to $800 and recharge at $200 to $500 as two standing lines. Frame A prints leak seal or valve replacement at $150 to $500 and recharge at $150 to $500, the readings standing apart by frame.
What does the visit total print at behind the rows, as reported?
Frame B prints a mini-split typical band at $150 to $650 beside its problem rows, and a diagnostic line at $75 to $150. Frame A prints its ductless row at $350 to $1,200 in place of one total, apart.
Is a problem row the same purchase as a new ductless installation or a whole-system replacement?
No. Each row prices one problem in one repair visit, priced by problem, off an $800 to $2,000+ compressor row in Frame B and a $1,500 to $2,800 compressor row in Frame C. The installation hub, central-air systems, window and portable units, and whole-system replacement sit in their own lanes, named apart.
