GradeMyQuote is a free, independent tool for U.S. homeowners comparing HVAC or plumbing contractor quotes. Upload 1–4 written quotes and get an A–F grade for each on price, scope, warranty, permit handling, and listed credentials, plus a side-by-side comparison that flags missing items and likely overcharges. Individual quotes are never shared with contractors.
