| Our take | The original R410A HD55, sold as a 113-pint unit, with no 65°F rating on record. Buy the HD55S instead, which has one. | A ductable 70-pint unit with 200 CFM for a sealed crawl space or basement that stays above the mid-50s. It stops dehumidifying below 50°F inlet air, and AprilAire publishes only an 80°F rating to judge it by. |

| Watch out for | Three units share the HD55 name: the original HD55 (R410A), the HD55S (R32, ENERGY STAR, gravity drain) and the HD55P (built-in pump). Not in the ENERGY STAR certified data. | AprilAire publishes only the legacy 80°F rating; there's no 65°F or 73°F figure and the E070 isn't on ENERGY STAR's list, so don't line its 70 up against current-test ratings. The warranty is void if defects result from not installing per AprilAire's instructions, and AprilAire recommends a professional install; labor is never covered. E070 Pro is an Amazon listing name, not an AprilAire model. Used units from private sellers or auction sites aren't covered. |
