← Mini-Split Install Bid Calculator
This calculator vs. a flat $2,800-a-head quote
“$2,800 a head” is not a price for a mini-split install — it is a price for one specific floor, head type, and line-set length, quietly applied to every head that calls in.
What a flat price per head is
A flat rate per head is the fastest way to quote a ductless install: multiply the head count by a number and read off a price. It is the number a homeowner holding a search-result special or a competitor's flyer will call and ask you to match, whatever their job actually needs.
The number behind it was set for one job — a first-floor wall-mount with a short line-set already covered by the equipment quote, an existing 240 V disconnect, and a gravity drain — and then reused for every install afterward, whether or not the next head looks anything like the one the rate was built on.
What this calculator is
This page keeps no account and sends nothing to a server. You enter head count and BTU size, head type, story height, total line-set feet against what the equipment quote already includes, and electrical and condensate extras, plus your own labor hours and material costs. It prices the story, the line-set, and every extra separately by kind, then returns the walk-away price and a bid price above your target margin — for this head, not a generic one.
| What a flat price per head does | What this calculator does instead |
|---|---|
| Charges the same $/head on a first-floor slab and a third-story ceiling cassette, even though indoor and line-set labor climb with every floor. | Prices story height as a separate factor on indoor and line-set labor, so a second- or third-story head costs more than the same head at grade. |
| Has no line for line-set feet beyond what the equipment quote already includes, regardless of whether the run is 15 ft or 50 ft. | Prices only the extra feet beyond the included length, by hours and material, so a long run costs more than a short one. |
| Charges the same rate for a standard wall mount as for a ceiling cassette or concealed ducted head, or for existing electrical as for a new 240 V circuit and a condensate pump. | Prices head type, electrical extras, and condensate separately, so a cassette with new electrical and a pump costs more than a wall mount on existing service. |
| Gives the estimator a number to quote, not a number to check a quote against. | Reports the walk-away price and the dollar gap against a flat per-head rate, so a shopped price can be scored against real cost before you commit to it. |
Two heads, the same floor-blind rate
Using this calculator's own shipped presets, at its own shipped shop rates ($42/hr installer wage, 30% burden, 15% overhead, a 22% target margin):
| Job | This calculator's price | The flat $3,902.33/head rate | Gap |
|---|---|---|---|
| Single-zone 12k wall-mount, first floor, 15 ft line-set fully included, existing electrical, gravity drain — the job the rate is set from | $3,902.33 bid price; $3,043.82 break-even cost | $3,902.33 (exactly $3,902.33/head — this rate is fit to this job) | No gap on the job the rate was built on. |
| Single-zone 18k wall-mount, second story, 35 ft line-set (20 ft beyond included), new 20-30A circuit, condensate pump | $6,140.00 bid price; $4,789.20 break-even cost | $3,902.33 | The rate quotes $886.86 below this job's own break-even cost — before a dollar of profit — and $2,237.66 below the calculator's own bid price. |
The $3,902.33/head rate is not invented, and it is not the marketing $2,800 figure either — it is this calculator's own price on the first-floor wall-mount preset, divided by that preset's own head count. It fits that one job by construction. Applied to the second-story head, it never sees the extra line-set, the new circuit, or the condensate pump at all. Run your own job's numbers in the calculator to see where it falls.
A flat per-head rate is not wrong because it is simple — it is wrong when it is applied outside the one head it was built for, and nothing about a flat number tells you when that has happened. This calculator does not know your local market; it replaces the arithmetic a flat rate skips.
Common questions
Why does a flat price per head get a mini-split install bid wrong?
Because the cost driver is story height, line-set feet beyond what the equipment quote already includes, head type, and electrical and condensate extras -- not a blended head count. Equipment cost scales with heads reasonably well, but a second-story head with extra line-set, a new 240 V circuit, and a condensate pump is doing far more labor than the same single head on a first-floor slab with a short included line-set and an existing disconnect, none of which shows up in the head count a flat rate is built from.
What does a flat price per head usually leave out entirely?
Line-set feet beyond the length the equipment quote already includes, story height (indoor and line-set labor climb with each floor), head type (a ceiling cassette or concealed ducted head costs more labor than a standard wall mount), a new or upgraded 240 V circuit, and a condensate pump where gravity drainage is not available. A first-floor wall-mount with a short included line-set is doing far less than a second-story head needing extra line-set, new electrical, and a pump -- and a per-head number has no line for any of it.
How big is the pricing gap in practice?
On this calculator's own shipped presets, at its own shipped shop rates: a single-zone 12k wall-mount on the first floor with 15 ft of included line-set prices at $3,902.33, or $3,902.33 a head. Applying that same rate to a single-zone 18k wall-mount on the second story with 35 ft of line-set (20 ft beyond the included length), a new 20-30A circuit, and a condensate pump quotes $3,902.33 for a job that actually breaks even at $4,789.20 -- $886.86 short before a dollar of profit, and $2,237.66 below the calculator's own $6,140.00 bid price.
Is a flat price per head ever the right way to quote?
For a narrow band of near-identical jobs -- first floor, standard wall mount, line-set within the included length, existing electrical, gravity drain -- a per-head rate can land close, and on this calculator's own easy preset it is exactly the rate that job supports, because it was set from that job. The risk is applying the same rate outside that band without noticing, because the rate does not know which head it was built on and neither does the estimator until story, line-set, head type, and electrical and condensate extras are actually spelled out.
Does this calculator know what materials or labor cost in my market?
No. It has no data on local material or labor rates. It takes head count and BTU size, head type, story height, line-set feet, and electrical and condensate extras, plus the labor hours, equipment costs, and wage you enter, and turns that into a price for this job -- the arithmetic a flat per-head rate skips, not a market survey.
