Questions

What is the Mountman HY10MAC002's real BTU?
It's certified to DOE at 6,250 BTU/h SACC (seasonally adjusted cooling capacity), the rating DOE requires for portable ACs. A box figure labeled ASHRAE is usually higher for the same unit because it comes from a different test: SACC vs ASHRAE.
Is it single hose or dual hose?
It was tested as a single hose unit, per the DOE record.
How big a room does it cool?
About 250 sq ft. ENERGY STAR's sizing chart calls for 6,000 BTU/h in rooms up to 250 sq ft. A sunny room, a kitchen or a high ceiling needs more.
How much does the Mountman HY10MAC002 cost to run for 8 hours?
About $1.26 for 8 hours of cooling: roughly 868 W at 18.16¢/kWh, the US residential average for August 2026 (EIA).
Who makes the Mountman HY10MAC002?
DOE's database has no manufacturer field, so the record doesn't say. It does show 2 brands filing one basic model, HY10MAC002: Mountman and Uthfy.
