Which size, with which air handler, and what indicative amount? The A5HP5 units run from 1.5 to 5 tons, on R-454B, with the A5AHV air handlers. ENERGY STAR lists the pairing on our product pages under its AHRI number for 2, 3.5 and 4 tons; for 1.5, 2.5 and 3 tons, it lists the same unit with an A5AHV, but under an AHRI number other than the one on our product pages.
