What information should I get from the HVAC contractor?
An HVAC proposal should identify the selected indoor and outdoor equipment, auxiliary heat requirements and the boundary between HVAC and electrical work. An undefined electrical allowance can leave circuits, disconnects, permits or service changes unresolved.
- Each contractor should identify who owns each item and how the plans will be coordinated before you accept the estimate.
When should the electrician review my service capacity?
Service capacity should be reviewed before selecting a larger upgrade. For PSE homes, heat pumps and water heaters are part of the utility’s engineering intake.
- The review may support existing capacity, distribution changes, managed loads or a larger service; the right scope depends on the selected equipment and accepted design.
What should the electrical agreement spell out?
The electrical agreement should name permit responsibility, any service or panel changes, outage planning and restoration. Current program eligibility comes from the administrator, so confirm it before including an incentive in your budget.
- If equipment selection changes, the electrical scope may need reassessment.
How should changes in equipment be handled?
A different heat pump or auxiliary heater can change electrical requirements. Agree who will send updated specifications to the electrician and whether the electrical price or design needs revision before equipment substitution.
- Confirm which contractor resolves electrical corrections that affect the HVAC installation schedule.
- Keep the final equipment information with the electrical permit and closeout record so later work can use the installed configuration rather than an outdated sales proposal.
