Ask about same-day diagnostics, transparent upfront pricing, and whether they perform Manual J load calculations to ensure your system is properly sized. Inquire about parts and labor warranties, maintenance plans that keep manufacturer coverage intact, and high-efficiency options that may qualify for rebates or financing. If you need urgent help, confirm their after-hours emergency availability and typical response times.
