AlorAir Sentinel HD55P with Built-In Pump
Model Sentinel HD55P
SCORE7.0 / 10
The pump model for a basement or crawl space that drops below 41°F, rated from 33°F. AlorAir publishes no 65°F rating and no lift height, so size it smaller than its 55 pints and measure the drain run first.

Before you buy
- No ENERGY STAR listing and no 65°F capacity; its gravity sibling, the HD55S, is listed at 36.33 pints at 65°F.
- Three units share the HD55 name: the original HD55 (R410A), the HD55S (R32, ENERGY STAR, gravity drain) and the HD55P (built-in pump).
- 6-year limited for orders from Apr 14, 2026: 2 years full, then refrigeration parts only. A unit sent in for inspection ships at your cost after 6 months, there's no in-home service, and coverage requires purchase from AlorAir or an authorized dealer.
