THE ESTIMATING ANSWER
For one dwelling heat-pump system, start with a defined scope and measurement basis. Record conditioned zones, equipment locations, distribution condition, line route and power requirements. Keep equipment, controls, connection materials and commissioning separate. Price the listed tasks separately and state the condition that would require a revision: Inadequate distribution or supply capacity changes the equipment and ancillary scope.
This guide uses a fictional project in Hamilton, Ontario: One dwelling heat-pump system. Its matching estimate and PDF give each scope decision a visible CAD cost line. Use the document to understand the structure; verify the actual building, product schedule, labour and supplier inputs before preparing a client quote.
1. Define the measured job
Install one selected central heat-pump system with a defined indoor and outdoor equipment arrangement after a qualified load and site assessment. Record conditioned zones, equipment locations, distribution condition, line route and power requirements. Record the measurements and existing condition in the estimate before turning quantities into line items. The scope should make clear why this is a separate project from a broader renovation or maintenance quote.
Measurement basis: Record conditioned zones, equipment locations, distribution condition, line route and power requirements.
2. Build a product and labour schedule
Keep equipment, controls, connection materials and commissioning separate. This example has 7 distinct lines, including load and site assessment allowance, outdoor unit allowance, indoor unit allowance. Use actual supplier prices and labour inputs for a customer job; the displayed amounts are fictional document inputs.
Selections to confirm: Keep equipment, controls, connection materials and commissioning separate.
3. Sequence the work and handoffs
A qualified designer must size the system; coordinate electrical and mechanical handoffs before installation. Show which task depends on access, a selected product or another trade. If that dependency is still open, label the price preliminary and identify the information needed before a firm quote.
Work sequence: A qualified designer must size the system; coordinate electrical and mechanical handoffs before installation.
4. Set a change boundary
Inadequate distribution or supply capacity changes the equipment and ancillary scope. The example excludes whole-building insulation retrofit, duct replacement or service upgrade. Record the discovery, agree the revised work and update the estimate before adding it to the job.
If the job changes: Inadequate distribution or supply capacity changes the equipment and ancillary scope.
Review the Canadian job address
Inspect the existing substrate, access and product selections at the property. Check any local trade or municipal requirements that apply and record unresolved conditions before preparing the final client document.
Count the actual units, site visits and selected products separately. A count in this example is a document input, not a substitute for inspecting the real property. The example amounts are fictional CAD document inputs, not current rates for Hamilton, Ontario or another community. A site visit and current supplier information are needed to replace them.
Work through the itemized calculation
Check each extension of quantity and rate in the paired PDF. Two lines from this project are:
- Outdoor unit allowance: 1 each × C$5,565.00 = C$5,565.00.
- Indoor unit allowance: 1 each × C$3,845.00 = C$3,845.00.
Adding all 7 rounded line amounts gives C$18,585.00. The PDF shows 0% tax and the same total before any markup. The sample shows 0% tax only to make the arithmetic visible. Determine any applicable GST, HST or PST and markup for the actual work before sharing a quote.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Load and site assessment allowance | 1 job | C$610.00 | C$610.00 |
| Outdoor unit allowance | 1 each | C$5,565.00 | C$5,565.00 |
| Indoor unit allowance | 1 each | C$3,845.00 | C$3,845.00 |
| Line and fitting allowance | 1 job | C$1,125.00 | C$1,125.00 |
| Equipment installation labour | 32 hours | C$150.00 | C$4,800.00 |
| Controls and electrical connection allowance | 1 job | C$1,725.00 | C$1,725.00 |
| Commissioning and handoff | 1 job | C$915.00 | C$915.00 |
| Illustrative subtotal | C$18,585.00 | ||
Scope and pricing boundaries
Install one selected central heat-pump system with a defined indoor and outdoor equipment arrangement after a qualified load and site assessment.
Outside this example: No whole-building insulation retrofit, duct replacement or service upgrade.
Keep the product allowance, installation work and any unresolved condition visible as separate decisions. If access or the selected product changes, update the affected quantity or rate and explain the revision before the client relies on the estimate.
Before you send the estimate
- Record conditioned zones, equipment locations, distribution condition, line route and power requirements.
- Keep equipment, controls, connection materials and commissioning separate.
- A qualified designer must size the system; coordinate electrical and mechanical handoffs before installation.
- Inadequate distribution or supply capacity changes the equipment and ancillary scope.
Check the business, client, property, dates, line extensions and notes. The central heat pump installation PDF example shows one way to present them. Its short PDF note lists the brief's scope exclusions; the fuller project limits above should guide your own scope.
