Start with system age and repair history
Write down the approximate equipment age, recent repair history, recurring issues, and whether comfort problems are isolated or whole-home issues.
This information helps frame the conversation, but the repair-versus-replacement decision should be based on a professional assessment and written estimate.
Ask about sizing and scope
Replacement planning should consider more than the outdoor unit. Duct condition, indoor equipment, thermostat controls, insulation, and system sizing may affect comfort and performance.
Ask whether the estimate includes equipment model details, labor scope, permits when relevant, warranty terms, and any required electrical or duct-related work.
Confirm provider coverage and basics
Before scheduling an estimate, confirm the provider serves the ZIP code, handles the requested HVAC work, and can explain license, insurance, diagnostic fee, and written estimate details.

Review official sources for incentives
If replacement equipment is connected to a rebate or incentive, verify the official program rules before purchase. Eligibility can depend on model numbers, efficiency ratings, installation details, and timing.
Do not rely on verbal rebate assumptions alone. Save official program pages, proposal details, invoices, and application confirmations.
