Call to schedule a diagnostic visit and ask for upfront, itemized pricing; sharing your system’s brand/model and any error codes or photos can speed up the quote. If you’re planning a replacement, ask about energy-efficient options, manufacturer warranties, available financing, and whether they perform a Manual J load calculation to size your system correctly. For peace of mind year-round, request a seasonal tune-up plan and confirm their availability for after-hours or emergency service so you’re covered when you need it most.
