Put the current complaints into the proposal
If the old system left a warm bedroom or a sticky indoor feel, make those issues part of the assessment. Give the equipment history and any building changes since it was installed. The existing capacity is information, not a completed sizing calculation. A new system should be selected against the house it will serve now rather than an assumption that the old arrangement was correct.
Compare work, not just model names
Ask for the indoor and outdoor equipment, controls, installation labor, and supporting connections to be identified. Clarify whether duct modifications, electrical work, drainage, or removal of existing equipment are included. Different proposals may cover different jobs even when the equipment looks similar. Compare those boundaries alongside efficiency information and the stated warranty terms before deciding what represents the better fit for the property.
Cooling performance needs a commissioning plan
Discuss how the installer will verify airflow, operation, and the completed setup. For a Wilmington household, explain both temperature complaints and moisture concerns in the rooms people use. Ask what the proposed design changes and how the handover will address settings and routine care. A new cabinet alone does not establish that the distribution or building condition behind a previous complaint has been corrected.
Arrange the work around the house
Call about replacement options with the address, access route, and occupied-space constraints. Confirm preparation, scheduling, interruptions, price, and how changes to the agreed work are handled. Ask who receives any later service concern and what follow-up is included. The goal is a complete installation decision you can understand, with the old comfort complaint connected to the new scope and its final checks.
