Send the complete HVAC equipment schedule before requesting a firm electrical quote. “We are installing a heat pump” leaves out details that can change the circuits, route and overall scope.
Which equipment details are needed?
Provide the exact outdoor-unit and indoor-unit model numbers, manufacturer electrical specifications and installation instructions. Include any air handler, supplementary electric heater or other powered equipment in the proposal. An equipment brochure showing heating output alone may not contain the electrical information needed.
Why mention backup heating?
The electrical scope depends on the complete system, not just the outdoor unit. Ask the HVAC contractor to identify the backup-heating arrangement and whether existing heating equipment will remain. Avoid comparing quotes based on different equipment schedules.
What photos help?
Send the panel exterior, proposed outdoor-unit location, indoor-equipment location and visible route between them. Note finished ceilings, crawlspaces or other access restrictions. Take photos only from safe, accessible positions; do not remove covers. Use our quote photo checklist.
Does a heat pump always require 200 amps?
No. A particular service size should not be assumed from the equipment name. Your electrician needs to assess the home and the proposed loads. Mention a planned EV charger, induction range or suite at the same time so separate projects do not overlook one another.
Who does the electrical work?
Ask the HVAC contractor whether electrical installation is included, subcontracted or arranged separately. Identify who supplies and installs each electrical component, who obtains the relevant permit, and who coordinates the connection date. Also clarify who handles controls and final system commissioning.
What if the HVAC model changes?
Send the revised specifications to the electrician before equipment is ordered or wiring work begins. Ask whether the price, circuit arrangement or schedule changes. Keep one final equipment list shared between both trades.
