Prepare the information an electrical professional needs to assess a heat pump installation without assuming an empty breaker space means spare capacity.

Quick answer: An empty breaker position does not establish that your home has enough electrical capacity for a proposed heat pump. Ask the quoting contractor how the electrical assessment will be completed and who is responsible for it. The assessment should relate to the actual equipment and the home's existing loads.
You can help by organizing information. You do not need to remove a panel cover, inspect wiring or calculate a service upgrade yourself.
Provide the proposed heat pump equipment details and identify any backup electric heat being considered. Mention planned changes such as an EV charger, induction range or other large electrical load. A quote based only on today's appliances may not address changes you already intend to make.
Ask whether the electrical portion is a firm scope or an allowance pending assessment. If the HVAC quote assumes an existing circuit can be reused, request confirmation of that assumption before equipment is ordered.
Do not remove the dead front or reach into a panel. If labels are missing or unreadable, report that instead of trying to trace circuits yourself. Keep clear of damaged or wet electrical equipment.
The assessment may identify a straightforward circuit installation, other electrical work or a need to consider an alternative equipment or load-management approach. Whether a particular option is suitable must be established for the home and equipment; a generic online panel-size rule cannot settle it.
Request the reason for the recommendation and a written scope. Separate the equipment price from circuit work, panel or service changes, permits, utility coordination and repairs to finishes where applicable. This avoids comparing a complete proposal with an equipment-only price.
Ask what must be completed before the HVAC installation and who coordinates the sequence. If another contractor or the utility is involved, identify the contact and the outstanding decision. Do not assume the HVAC start date includes all external appointments automatically.
For a condo or townhouse, establish which electrical equipment you control and which requires building-management access. Written project coordination is useful even before the technical design is finalized.
Record the selected equipment, electrical work included, exclusions and responsibility for applicable permits. Technical Safety BC's contractor guidance can help you check the appropriate licence scope; the relevant authority and requirements still depend on the work and location.
At handover, ask for the completed electrical documentation that applies to the project and an explanation of the normal controls and isolation points. That explanation is for safe operation and service coordination, not an invitation to open electrical compartments.
