Clear HVAC Costs

HVAC Quote Checker is a free online tool that helps homeowners evaluate contractor bids for HVAC replacement or installation. It takes a quote total, home size, and system type, then compares the price against a national planning model and checks whether the written scope covers key items like equipment model numbers, load calculation, permits, ductwork, startup testing, and warranty terms. The tool produces a sanity score and highlights questions to resolve with the contractor, rather than declaring a bid fair or unfair based on price alone. It also provides a 3-bid checklist, red flags to watch for, and system-specific guidance for central air, heat pumps, furnaces, and ductless mini splits. The checker is built around common HVAC replacement risks and is updated as of August 10, 2026.
