Installed planning range
Ready to calculate
National allowances are filled in. Calculate now or edit them to match your written scope.
Scope, itemized amounts and limits
Each low, typical and high total adds that column once. Endpoints are allowance sums, not statistical confidence limits. The guide high is not a price ceiling.
Tax, financing, incentives and unknown work are excluded.
Formula v2.1. Sources checked October 14, 2026. Method and corrections.
Paper method and limits
Add each low column once, then each typical column and each high column. An installed bundle already includes equipment and labor. Add only separately priced extras. Cooling already included adds no second amount. Keep unknown work outside the subtotal. Guide endpoints are not guaranteed prices.
National planning allowances and source limits
US dollars, checked October 14, 2026. These defaults include equipment and installation once. The typical column is a calculated allowance, not a measured national median. Each value is editable in the tool.
| Scenario | Low | Typical allowance | High guide endpoint | Efficiency and scope |
|---|---|---|---|---|
| Air-source heat pump installation | $6,000 | $16,500 | $25,000 | Exact efficiency not stated. Residential air-source installed envelope. HomeGuide includes air handler; exact Carrier indoor scope must be checked. Backup heat, new ducts and panel work remain unconfirmed. The guide upper endpoint is not a price ceiling. Sources: Carrier heat pump cost guide; HomeGuide heat pump cost guide |
Low and high span the cited guide ranges. Typical is the median of the range midpoints, rounded to a whole dollar. It is a planning amount, not a measured project median.
Related source records are not claimed to be independent surveys. This is not one controlled set of equal-scope jobs. Unknown capacity stays unknown. No size, weather or location price multiplier is used.
- Carrier heat pump cost guide. Published/revised: 2026 guide; exact revision date not shown. Checked: 2026-10-14. Heat pump installed $6,000-$25,000; premium/complex work can exceed this. Indoor and backup scope must be checked.
- HomeGuide heat pump cost guide. Published/revised: 2025-10-30. Checked: 2026-10-14. Air-source installed $10,000-$25,000+, including air handler. No arbitrary premium for a cold-climate label.
Published scopes differ. Upper endpoints marked “+” in a source are open-ended. Taxes, incentives, financing and unresolved site work are outside the subtotal. Read the method and correction history.

- Verdict: use the heat pump installation cost calculator for a defined subtotal
This heat pump installation cost calculator gives a planning range from editable national air-source allowances. You can get an estimate before receiving bids. The result keeps the installed base, separate extras and unknown site work apart. Ground-source and other unsupported scopes use their own guides rather than an automatic price here.
The default combines Carrier and HomeGuide installed air-source guide ranges, with an explicitly derived typical point. It is not an observed median price or an exact model quote. Backup, power, ducts and removal need their own stated scope. Count unit and labor once inside a bundle. Unknown capacity stays unknown. Site work stays unpriced until you have a stated amount.
Heat pump installation cost calculator: choose replacement scope
Choose replacement if an existing system is being changed. Choose New installation if the house is adding this unit. The base guide envelope does not receive a fixed first-install surcharge. Add only a stated scope difference.
The installation cost parent explains the unit boundary. For both units changing, use the matched heat pump and air handler guide. The indoor unit may already be in an installed guide range.
Capacity, efficiency and indoor unit
Capacity and rating fields are optional context. If you lack full model or load evidence, leave them blank. The result states unknown. Entering a capacity does not apply a hidden dollars-per-ton rule.
ACCA Manual J covers the load and Manual S covers selection. The price tool performs neither task. A price range cannot prove low-temperature heating fit.
| Field | Record to enter | What the tool does |
|---|---|---|
| Capacity | Stated load or full model figure | Prints the context without scaling price |
| Unit | Cooling tons, cooling BTU/h or heating output | Preserves the boundary |
| SEER2 | Full matched-system rating if known | Records it without a guessed premium |
| Reference | Guide basis or written model/quote | Names the price evidence |
| Indoor equipment | Stated in the scope record | Not automatically added twice |

For colder terms, retain heating output and backup evidence separately. The cold-climate guide explains those fields.
Backup and power work
The power/backup extra field requires a separate written amount if you price it. A heat kit included in the base adds no second charge. An unpriced need stays on the unknown list.
Do not substitute a gas-furnace backup amount for resistance heat without defining the system. The dual-fuel guide describes that separate boundary. If your written bundle covers a new full hybrid setup, name it as your own quote scope rather than the default air-source guide.
| Scope state | Use it when | Result |
|---|---|---|
| Unknown | Need or price not yet settled | Listed outside subtotal |
| Included/not required | Written base covers it or assessment says not needed | No added amount |
| Extra | Separately priced work outside base | Low/typical/high added once |

The tool gives no circuit, breaker or control wiring instructions. Actual unit and checked supply scope govern those tasks.
Duct, line-set, drainage and removal allowances
A retained network still needs a stated airflow scope. A new indoor cabinet is not proof that every duct remains suitable. Use a written repair or swap bid before entering an extra.
Record actual line-set and drainage work. Similar rated capacity does not prove the retained parts suit the new full model. The EPA transition page gives wider refrigerant context. Maker records govern the job.
Removal is counted only when it is outside the base. Name old units and any fuel components covered. An oil tank is not by itself included with cabinet haul-away. Access and surface repair also need explicit duties.
Heat pump installation cost calculator: budget breakdown
The output shows low-to-high installed allowances and a typical planning point. It lists each amount added and each unpriced scope. A smaller subtotal can mean more tasks remain open.
Taxes, loan costs, rebates and future energy savings are excluded. They need separate evidence and periods. Source high endpoints marked open-ended are not maximum possible prices.
| Result line | Meaning |
|---|---|
| Installed base | One equipment-plus-installation allowance |
| Separate equipment/labor | Used only after changing the layout and entering written amounts |
| Extras | Separately priced tasks outside base |
| Unknown list | Names of scope not yet priced |
| Typical | Derived or entered planning amount, not probability |

Calculation method and paper worksheet
Add each column separately. In bundle mode, base already includes unit and fitting work. In separate mode, add stated unit and install amounts. Then add each true extra in that column.
Low total is the sum of lows. Typical total is the sum of typical amounts. High total is the sum of highs. A known fixed quote can use the same amount in all three fields.
Typical must be within low and high. Reversed ranges stop the result and keep entries. No incomplete or invalid input produces a fake full total.
Read a bundle without inferring a dealer's margin
A full installed bid can be compared with another full installed bid. It does not need an invented split between unit and labor. The written scope is what makes the total useful.
Do not subtract an unrelated internet unit listing from the bundle and call the remainder labor. It may cover controls, materials, disposal and business costs. A different seller's unit price is not a breakdown of this bidder's package.
If the bid gives real separate amounts, switch to that layout. The old bundle amounts clear so they are not silently relabelled as unit-only prices. Enter the actual source and all required amounts.
Source and scope record
The national source block names the ranges and dates. It distinguishes Carrier's broad guide from HomeGuide's air-handler-included scope. The derived typical point remains labelled.
A check date states when the record was read. It does not guarantee a current offer at your address. There is no installer promise, ZIP gate or phone form attached to this estimate.
If your job has an unsupported unit or a source gap, use its dedicated guide and a written override. Ground-source loop work is not priced by the air-source preset. The geothermal guide retains that boundary.
Quote checklist and print view
Keep both full models, matched performance and load source. Record backup, controls, power, ducts and line-set scope. State removal, permits and restoration. Align those fields before comparing totals.
The print action keeps the inputs and result. Editing marks the old result stale. Recalculate before using a revised estimate. Reset restores national defaults and clears the old output.
Without JavaScript, the source table and fields remain visible. Use the column-sum formula on paper. List every unknown beside the subtotal so the printed amount cannot be mistaken for a full bid.
Read the printed subtotal with the unknown list
The low and high numbers answer the priced part of the job. The unknown list answers what evidence is still missing. Keep both on the printed worksheet. Open lines can matter more than the difference between two base allowances.
Suppose one bid marks all ducts included. Another lists unit and leaves duct work open. Their subtotals are not yet equal-scope prices. Ask for the missing boundary before calling the smaller amount the lower total for the same job.
Not every unknown will become an extra. Some may be included or not required after check. The tool keeps that decision open instead of choosing it from a blank amount.
Keep range endpoints tied to the same task
Low, typical and high should describe one coherent scope. Do not use a unit-only low and a full installed high without stating the difference. A range is useful when its ends refer to the same task.
The national default is broad and names its source differences. Your written override can be narrower once the job is known. Keep the source or model field with those new numbers.
For a fixed bid, enter equal endpoints and its stated typical amount. For an allowance range, use a supported typical point inside it. Do not narrow the figures merely to make the result look precise.
When a required task is not priced
If power, access or drainage work is required but unpriced, leave it unknown. Do not enter a token amount to bypass validation. The base subtotal can still show the missing task beside it.
A bidder may later include that work in the base or price it separately. Record which and count it once. Keep the prior worksheet so a change in total can be traced to actual added scope.
Check the units on every saved amount
Each price field is in US dollars for the stated task. A monthly fuel bill is not a one-time installed amount. A unit-only listing is not an installed bundle. Keep the scope and period beside each amount.
The low, typical and high figures can all be the same for a fixed quote. That does not make the quote a range from several jobs. It is one stated amount for one stated scope. The output should still keep its source.
If you later receive another bid, save its full model and scope too. Compare the same included work before changing the worksheet. A different total can reflect another task as well as another price.
The tool adds the numbers you enter. It cannot decide which bid has resolved a missing site line. Keep the unknown list visible while you gather that record.
FAQ
Can I calculate before receiving a quote?
Yes. The national base allowances are filled in, so you can get a planning subtotal without entering your own price. The output states source and unknown scope. Replace the defaults with equal-scope written amounts when available. The starting range does not promise a home-specific installed price or certify which unit suits the building.
Does the default add another air handler price?
No. The source record explains that HomeGuide's installed air-source range includes an air handler. The tool does not by itself add another indoor-unit allowance. If your own written scope separates those prices, enter the non-overlapping lines. Keep the actual indoor/outdoor match and backup kit so the component list agrees with the total.
Why is unknown electrical work outside the total?
The tool has no checked supply scope for your house. An unknown line is not free work and does not prove an upgrade is needed. Keep it open until the actual bid defines the need and price. The worksheet then adds a true extra once or marks it included, rather than guessing from rated tonnage.
Can I use this default for geothermal?
No. The automatic base is residential air-source context. A ground-source job needs loop, drilling and site records that the preset does not supply. Use the dedicated geothermal guide and a full written scope. Do not apply an invented loop multiplier or present an indoor-unit price as a full new ground-source install total.
